GAS PIPING HANDBOOK


PREFACE

This Book is dedicated to the memory of Paul Bernauer.

Louisville Gas and Electric Company (LG&E) provides retail gas and electric service in a defined service territory in and around the Metro Louisville, Kentucky area. The Commercial & Industrial Customer Gas Piping Handbook is intended to address natural gas service issues for Commercial and Industrial customers within the prescribed service territory. This Document is intended to supplement the Customer Gas Piping Handbook. A separate document, “Electric Service Handbook”, details the requirements for electric service. Customer Gas Piping Handbooks The Customer Gas Piping Handbooks (both Commercial and Residential) prescribe LG&E’s standards with respect to gas service and meter installations pursuant to the rules and regulations of the Kentucky Public Service Commission (KPSC). All piping used for gas service lines and meter installations must be installed in accordance with the specifications provided by LG&E and will be subject to inspection and testing by LG&E. In the event that special circumstances prevent compliance with the service line specifications prescribed within this handbook, LG&E will give proper consideration to alternative methods, provided that applicable regulations are not violated and that safety and reliability are not jeopardized. The Customer has the responsibility of notifying LG&E of any changes to the piping, appliances, or building structure that may affect safety or gas system performance. This Commercial and Industrial Customer Gas Piping Handbook includes standards pertaining to the Commercial and Industrial Customers’ service, meter loop and house line piping, in the interest of uniform and safe operations. The standards for piping are generally applicable for replacement or relocation of existing facilities. The Commercial and Industrial Customer Gas Piping Handbook is applicable to customers with a total connected natural gas load of 500,000 BTUH or greater. LG&E reserves the right to modify the requirements found in this handbook or any of its service policies, procedures and/or standards at any time. It is the responsibility of the Customer to ensure that any reference document is the version currently approved for use by LG&E. It is also the responsibility of the Customer to notify LG&E of any changes to natural gas facilities that may affect safety or natural gas system performance. By publishing this handbook, LG&E does not assume liability or responsibility for house piping, appliance installation, or appliance operation. LG&E maintains the right to refuse to supply gas to piping or appliances that are installed or operated in a potentially unsafe manner. In addition, LG&E is not responsible for continuing inspection or surveillance of Customers’ house piping, appliances, or appliance operation.

EXCAVATION SAFETY Call before you dig – It is the Law The Underground Facility Damage Prevention Act (KRS 367.901-367.917) was enacted by the Kentucky legislature in 1994. This law requires all persons excavating in the state of Kentucky to have underground facilities located prior to starting excavations. Violators of this law may be subject to fines and/or criminal prosecution. Kentucky 811 is the answer to the continuing problem of damage to underground facilities. Kentucky 811 provides a communication link between excavators and operators of underground utilities. Kentucky 811 is a non-profit organization made up of owners and operators of underground facilities in the Commonwealth of Kentucky.

Please call Kentucky 811 at least two business days and not more than ten business days prior to your planned excavation with the information listed below. There is no cost to the caller! • Identity of contractor or excavator: name,

address, etc. • Dig site location: County, nearest city,

inside/outside city limits, street name or highway name, address number, the nearest cross street intersection or other description if address is not available.

• Digging information: Type of work, depth of dig,

location within property or right-of-way, method of excavation.

• Estimated date and time of excavation. In turn, Kentucky 811 will contact its member companies for you to have the underground facilities located in the vicinity of your planned excavation. In addition, they will advise you as to what utilities will be notified, and will provide you with a request number for your reference and documentation.

Both LG&E and Customer-owned natural gas facilities must be planned, designed, built, maintained, and operated in a manner that minimizes the risk of injury and property damage during construction and throughout the life of the facility. Natural Gas Safety It is important that users know how to safely use natural gas and care for natural gas appliances. One of the first steps to prevent accidents is to ensure that natural gas appliances and equipment have been properly installed, adjusted, vented and inspected. Appliances should be installed, serviced and repaired by professionals. Other safety precautions that should be taken include the following: • Follow manufacturers’ instructions for the installation, operation and maintenance of gas equipment and

appliances. • Since burning natural gas produces a high radiant heat, keep flammable materials (e.g., cloth, paper, paints,

and solvents) away from appliances. • Provide proper ventilation in areas around furnaces, water heaters, dryers, ranges, etc. • Have routine maintenance performed on appliances to keep them clean and in proper working order. • Ensure that all vents and chimneys are free from blockage. • Clean or change filters on furnaces and dryers regularly. • Maintain the gas lines that are located inside and outside the house to prevent leaks. The gas service lines

buried from the property line to the house and all house line piping within the house are the responsibility of the property owner. LG&E will periodically survey all outside piping for leaks and will advise you if any maintenance is required on your portion of the service line. LG&E will also inform you of any corrosion that is discovered on any outside piping that is exposed to the weather and advise you to paint the affected area.

• Contact Kentucky 811 to determine the location of utility-owned service lines (including LG&E’s natural gas

lines) before you begin any yard excavation; dial 811. This is a free service. • Do not operate any electrical switches, equipment or appliances or use open flames if you smell a natural gas

odor. Leaking natural gas can ignite.


What to Do If You Smell Natural Gas • If you smell gas and cannot find the source(s), immediately go to a location where no natural gas odor exists,

such as a neighbor’s house, and call LG&E Natural Gas Trouble at (502) 589-5511 (outside Louisville at (800) 331-7370). A spark from using a telephone or cellular telephone inside the house could ignite the gas.

• If the odor is faint, get everyone outside and leave doors and windows open to ventilate the area. A faint odor

of gas may mean that a pilot light has gone out and should be re-lit. • If the odor is strong, evacuate the building immediately. • Never use a telephone or cellular telephone, switch a light on or off, or light a match if you smell natural gas. • Never look for a natural gas leak with a lighted flame or match. • Do not try to re-light a gas furnace, water heater, or range.


Definitions Appliance (Gas Appliance) – Any device that utilizes natural gas as a fuel or raw material to produce light, heat, power, refrigeration, or air conditioning. Approved Gas Valve – A natural gas valve that meets or exceeds the minimum requirements of applicable federal, state, and local codes and regulations. Branched Service Line – A company service line that branches off from an adjacent company service to serve a total of two (2) customer service lines that are on adjacent or adjoining properties BTU – British Thermal Unit. A measure of heat energy. One BTU is the quantity of heat that will raise the temperature of one pound of distilled water by one degree Fahrenheit (1oF) at 70 degrees Fahrenheit (70oF). BTUH Input Rating – The heat energy input, in terms of BTU per hour, required to properly operate a gas-burning appliance. The amount of natural gas needed to operate the appliance is determined by the BTU input rating. One standard cubic foot of natural gas will produce slightly over 1,000 BTUs in normal efficient combustion. Cathodically Protected Piping – Underground coated steel piping that has cathodic protection applied to retard corrosion. The cathodic protection can be provided by the use of galvanic anodes, such as magnesium anodes. Company – When used herein, refers to Louisville Gas and Electric Company (LG&E), a wholly owned subsidiary of E.ON U.S. Company’s Service Connection – Piping from LG&E's gas main to a point within one foot of the Customer's property line or easement line, adjacent to the main, for the purpose of supplying gas to the Customer's service line. Corrosion Prevention – Measures taken to prevent corrosion and prolong the life of buried metallic piping, and aboveground piping exposed to weather or a corrosive environment. CSST – Corrugated Stainless Steel Tubing. Gas house piping systems incorporating corrugated stainless steel tubing and custom designed fittings are for use above ground only. In order to be acceptable under code requirements, each installer must be certified as trained by the agent(s) or

manufacturer(s) of system(s) being used and must be trained on all installation requirements of that manufacturer. CTS – Copper Tube Size. The size convention used to describe the size of polyethylene gas piping in terms of standard copper tubing. The actual outside diameter of CTS-sized tubing is one-eighth inch (0.125") larger than the nominal CTS. Customer Contribution – The amount of money that the Customer must contribute to obtain natural gas service. A Customer contribution may be required when a pipeline must be either extended or tapped to provide service to the Customer. Customer Service Line – Piping installed by the Customer from LG&E's company service connection (usually at the property line) to the inlet side of the gas meter. The customer is responsible for maintenance of this line. Houseline – Piping installed by the Customer from the outlet of the gas meter to all appliance and equipment connections. This definition includes piping installed underground or aboveground beyond the outlet of the meter. The customer is responsible for maintenance of the houseline piping. FT Customer – Firm Transport Customer; a customer who purchases gas from a gas company (other than LG&E) and uses LG&E facilities to transport the gas to the customer’s service. Restrictions apply; contact a customer account representative for more information. IPS – Iron Pipe Size. The size convention used to describe the size of polyethylene gas pipe in terms of nominal steel pipe of the same outside diameter. Listed – Material and equipment certified to meet the quality and performance standards specified by a nationally recognized testing laboratory or quality assurance organization.


Low, Elevated, Medium, And High Pressure – LG&E's classifications of operating pressures in the gas mains throughout its gas system are as follows:

a. Low Pressure – The system operating pressure is essentially the same as the pressure delivered to each Customer’s meter and house line (i.e., 0.25 PSIG (seven inches Water Column (7” W.C.)). b. Elevated Pressure – LG&E’s elevated pressure systems operate at 2.0 PSIG at their sources of gas supply. A pressure regulator is required ahead of each Customer’s meter to maintain a constant standard delivery pressure of 0.25 PSIG (i.e., 4 ounces per square inch or 7 inches Water Column). c. Medium Pressure – LG&E’s medium pressure systems operate at pressures higher than 2.0 PSIG up to 60 PSIG. LG&E has several medium pressure systems operating at different pressures. A pressure regulator is required ahead of each Customer’s meter to maintain a constant delivery pressure that is normally the standard 0.25 PSIG. Higher delivery pressure can be delivered to the Customer if necessary, limited by the characteristics and operating restraints for the particular medium pressure system. d. High Pressure – LG&E’s designation for high pressure includes any gas transmission system or distribution system that is subject to operation at over 60 PSIG. Pressure regulation equipment is typically required both at the property line and ahead of each Customer’s meter to maintain a constant delivery pressure that may be the standard 0.25 PSIG or higher if necessary.

Main – Gas system piping located in a public highway, street, alley or private easement that is used to distribute gas. Meter Loop – Piping provided by the Customer to accommodate the installation of the gas meter(s). PSIG – Pounds per Square Inch Gauge. A standard unit of measurement for describing the pressure of a gas or a liquid. SDR – Standard Dimensional Ratio. A numerical term used to describe the wall thickness of polyethylene pipe. SDR is derived by dividing the actual outside diameter of the pipe by the wall

thickness and is an indication of the strength of the pipe.

Service Head Adapter – A transition fitting that adapts polyethylene gas pipe to steel pipe, in a manner in which the polyethylene pipe is shielded against damage from physical force and solar radiation, with all pressure containing metallic components located above ground. Standard Delivery Pressure – The gas pressure normally delivered to residential and small commercial Customers, which is approximately four ounces (4 oz) per square inch, seven inches (7”) of Water Column, or 0.25 PSIG. Tamperproof Gas Valve – A gas valve in which the core cannot be easily removed, either accidentally or intentionally, with ordinary hand tools. Tamperproof valves include a stem locking mechanism. Total Connected Load – The total heat input in BTUH for all gas burning appliances and equipment installed. W.C. – Water column pressure. A standard unit of measurement for describing the pressure that is expressed in terms of a water depth exerting an equivalent force. Typical gas pressure delivered to Customer's house piping 7" W.C., which is approximately 0.25 PSIG. The loss in gas pressure that results from gas flowing through a piping system is generally expressed in inches of W.C. drop.

8.7.D. Easements/rights-of-way are not required for customers with existing meters unless the

service is being relocated and site conditions dictate the need for additional easements. 8.8. Install Customer Service Line (if applicable)

8.8.A. Plan your work.

• Planning is vital for obtaining a successful natural gas project (e.g., service, installation, or repair). It includes, but is not limited to, reading and following appropriate sections of the LG&E Handbook, obtaining all necessary permits, deeds and/or easements, and acquiring necessary materials and equipment. If you have questions concerning your project, contact a LG&E Account Representative.

• NOTE:

1. Commercial Customers will need to install Customer provided facilities

(e.g., service line, meter loop and house line piping). 2. If the existing Customer service line, meter loop or house line piping is not

adequate because of the installation of a new high BTUH rating appliance (e.g., generators, swimming pool heaters, etc.), the Customer will need to install the appropriate facility.

3. Customers are responsible for any necessary maintenance of these

Customer metering facilities. Including but not limited to painting, land maintenance, and regular valve greasing.

8.8.B. Avoid damaging the tracer wire.

• Care must be taken to avoid damage to the tracing wire during placement and

compaction of backfill. • Tracing wire must be intact, or be repaired before service will be connected.

8.8.C. Provide a two foot by four foot (2’ x 4’ x main depth) excavation hole at the property

line for new or replacement service lines. • Customers are required to excavate a 2’ x 4’ hole for new or replacement service

lines. • The excavation depth should extend 1 foot below the depth of the LG&E gas main.

LG&E distribution mains are typically 24-36 inches below grade.


8.8.D. Use a clamp on the service riser.

• The service riser must be securely supported using split ring clamps or substantial

mounting brackets in accordance with the applicable meter loop drawing. • Polyethylene pipe or flexible riser casing will not adequately support the meter setting.

8.9. Install Meter loop

8.9.A. Do not use full face gaskets or semi-metallic spiral wound gaskets on the meter

loop. • It is the experience of LG&E SR&O that full face gaskets are prone to leakage and are

more difficult to replace than standard ring gaskets. 8.9.B. Make sure that the meter loop is installed at a proper height (not too low or too

high) (i.e., service head adapter below grade).

• The meter loop shall be installed such that the bottom of service head adapter is either at a minimum of six inches (6”) or a maximum of twelve inches (12”) above grade.

8.10. Contact the Commercial Load Designer for Service Line and Meter Loop Visual Inspection

8.10.A. After installing the meter loop and prior to testing the house line piping, contact the

commercial service designer for service line and meter loop inspection. 8.10.B. The Commercial Gas Inspection Request Form, found in section: Supplemental

Information, should be faxed to the Commercial Service Designer. 8.10.C. LG&E will visually inspect the Customer service line and meter loop to ensure compliance

with applicable material and installation specifications. 8.10.D. After the visual inspection is completed and has PASSED the inspection, a hang tag

indicating the service has been inspected will be left at the meter loop.

8.11. Install and Pressure Test the House Line Piping

8.11.A. Make sure that the house line piping is ready.

• To qualify for natural gas service, the house line piping system must be extended to an operable natural gas burning appliance(s) or to a plugged valve(s) at the proposed appliance(s) locations.

• Gas service will not be established by LG&E unless all gas outlets are secured or

connected. 8.11.B. Pressure test the house line piping.

• House line piping should be pressure tested to detect leaks prior to contacting LG&E

for service connection. The Customer or Customer Representative should pressure test the meter loop and house lines to ensure there is not a leak.

• The pressure test is to be left on the houseline and meter loop until LG&E SR&O has

completed all LG&E inspections. • Strainers and Blow Down (Purge) Piping are to be tested with the meter and service

line.


• Install Piping Paddle Blinds or “Skillets”

1. Prior to pressure test, install pipe paddle blinds, also called “skillets,”

upstream and downstream of regulators. 2. Be sure to use skillets that are ASME rated equal to or greater than the

pressures that will be experienced during the test. 3. The skillets are supplied by the Gas Piping Contractor and should remain

installed until LG&E SR&O has tested the house lines. Skillets should not be installed at the inlet and outlet of the meter. On Low Pressure (4 oz, 0.25 psig, 7 in wc) services that will not have a regulator, skillets should be installed downstream of the service valve.

4. The Gas Piping Contractor is responsible for removing the “skillets” after

LG&E SR&O testing has been completed.

• Pressurize the system 1. Low Pressure House Lines (4 oz, 0.25 psig, 7 in wc) are to be tested at a

minimum of 3 PSI. 2. House Lines operating at pressures greater than Low Pressure, must be

tested at a minimum of 1.5 times the house line operating pressure.

8.12. Contact the Operations Service Center to Connect the Service

8.12.A. Contact Louisville & Bardstown Service Area, Muldraugh Service Area, or the Magnolia

Service Area Operations Center to connect the service (reference section: Important Telephone Numbers for contact information).

8.12.B. To qualify for connection of the Customer service to LG&E’s company service, the

following items must be completed: • A request for service must be established through the Business Service Centers. • To have the Customer service connected to LG&E’s company service, a written

request should be faxed to the appropriate LG&E Operations Center.

1. The form for the request is included in Section: Supplemental Information. 2. Note: Installers or Customers will be required to provide the Customer

account number for each address. 3. All Customer-provided facilities must be installed.

8.12.C. Allow adequate time for LG&E to construct/install facilities. • The Customer should allow a reasonable time subsequent to the Customer's service

application to enable the Company to construct or install the facilities required for such service. This construction time requirement may vary significantly depending on the type of facilities required for service.


8.12.D. Allow adequate time for LG&E to get utility locates.

• In accordance with the Excavation Safety section, LG&E is required to provide prior

notification for planned excavation work.

• Thus, if LG&E needs to excavate to provide gas service, it will need to wait at least two full business days until other utility companies have located and mark their buried utilities with color-coded paint, flags or stakes.

8.12.E. Commercial Customer service lines will typically be left off at the street, but will

have gas in the line.

• ONLY LG&E is authorized to turn on/activate gas service through the commercial rotary or diaphragm gas meter.

8.13. Install and “Activate” Fire Suppression Systems

8.13.A. Fire suppression systems must be installed and actively protecting the Customer

facility/building prior to gas meter activation.

8.14. Contact LG&E SR&O for Commercial Meter Installation, Testing & Turn On 8.14.A. Only LG&E is authorized to turn on the gas meter. Customers and Customer

Representatives who activate service through meters will be held responsible for damages.

8.14.B. Contact SR&O for Commercial meter tests and installation after the service has been tested and connected by the Operations Service Center.

• SR&O requires 2 business days advance notice to have the rotary meter activated. • Failure to confirm a scheduled date with SR&O, or failure to complete preparations

prior to the scheduled turn on date will result in a delay until the next available scheduled turn on date.

8.15. Be present for the activation of gas service.

8.15.A. To activate natural gas service for new service connection, service replacement, house

line repair, etc., LG&E needs access to all gas appliances.

• It is imperative that the Customer be present to grant access to the premises. • For Commercial and Industrial customers, a Customer Representative capable of

lighting/relighting the equipment should be available. Customers are encouraged to solicit manufacturer factory representatives for inspection of special or proprietary equipment; LG&E will not be responsible for damages due to improperly installed equipment.

• Remove all protective end coverings from the equipment on the day of the scheduled

installation. • The excavation at the meter loop should be backfilled following the service test or

covered with street plates/walking boards to allow LG&E safe working access to the meter loop.

• If the regulators have control lines, the final connection from the house line to the

regulator is to be made following the house line pressure test.


• The house line system must be extended to an operable natural gas burning appliance(s) or to a plugged valve(s) at the proposed appliance(s) locations.

• For a service line supplying gas to multiple meters, the inlet side to all proposed meter

loops must be completed and the house line from at least one meter must be connected to an operable appliance or to plugged valves at the proposed appliance locations.

8.15.B. After a request for meter turn-on has been made, LG&E will perform the following:

1. LG&E will witness the meter loop pressure tests. LG&E will visually inspect the house line piping, to the extent accessible, for safe installation.

2. If the connection to the existing house piping system is made prior to

LG&E’s inspection and witness of pressure test of the new installation, the entire house line piping system shall be subject to a pressure test prior to reactivation.

3. LG&E will visually check appliances that are in place for apparent proper

installation to the extent practicable. To check appliances, LG&E will need access to the premises.

4. If the inspections performed by LG&E are satisfactory, the Customer’s

service line will be connected to the Company’s service line and the meter will be placed.

5. Gas will not be turned on to a house piping system believed to be unsafe,

cannot be properly tested, or is leaking.

extension and/or enhancement of one or more existing gas systems. 18.1.B. LG&E Account Representatives / Customer Coordinators must be contacted as soon as

possible with loading information to initiate review by LG&E design personnel. 18.1.C. For commercial and industrial loads, the Gas Commercial Service Designer should be

contacted for service line sizing recommendation, and meter loop design information.

• The Gas Commercial Service Designer will recommend a service line size and path based on the information that he/she is given by the Customer. It is the responsibility of the Customer to ensure the Commercial Service Designer has the correct information by completing and submitting the Commercial & Industrial Gas Load Data Sheet.

1. Each gas service line must be of sufficient size to meet the maximum

usage demand. This demand should be determined by adding the BTUH input of all connected appliances or equipment subject to simultaneous operation.

2. The service line size required is dependent upon the operating pressure of

the system to which it is connected, the length, as well as the maximum usage demand.

3. Some allowance should be made for future installation of additional

appliances.


18.2. Sizing

18.2.A. For reference, the service line size may be determined from the service line capacity charts

in Tables 18.1, 18.2, and 18.3. Many commercial and industrial loads will exceed the capacity listed in these charts.

to allow sufficient room for meter loop maintenance.


GAS METER LOOP SIZE, CAPACITY & PRESSURE 33. Meter Capacity

33.1. General

33.1.A. To assure proper operation, each gas meter must be the proper size and type for the

maximum gas demand and required pressure. The maximum gas demand is determined by adding the BTU input ratings of all gas burning devices that may possibly be operated simultaneously.

33.1.B. Furnaces, space heaters, water heaters, boilers, pool heaters, fireplace logs, gas lights,

gas clothes dryers and gas generators should be included at their maximum input ratings.

33.1.C. Domestic kitchen ranges and outside grills may be considered to be 30,000 and 20,000 BTUH respectively as they rarely are operated at full capacity for extended periods with other appliances.

33.1.D. The Gas Commercial Service Designer will select a meter and meter loop that will satisfy

the load demands that the Customer submits on the Commercial & Industrial Gas Load Data Sheet found in section: Supplemental Information.

33.2. Diverse Load Requiring Multiple Meters

33.2.A. Certain types of commercial and industrial loads may require multiple meters for the same

building, serving the same Customer.

• At the discretion of LG&E, customers with variable loads, such as process and heating that differ by an order of magnitude, may be required to install a meter manifold for multiple meters.

34. Meter Loop Delivery Temperature

34.1. General 34.1.A. The gas delivery temperature shall be assumed to be 60 degrees Fahrenheit. 34.1.B. The company reserves the right, for billing purposes, to correct as necessary the actual

temperature in the case of large volume customers. 35. Meter Loop Delivery Pressures

35.1. General

35.1.A. Only LG&E representatives are authorized to make adjustments on the meter loop

pressure regulation equipment. 35.1.B. Unauthorized adjustment of meter loop regulation equipment may result in civil or criminal

action against the Customer, or a discontinuation of service. 35.2. Standard Delivery Pressure

35.2.A. Standard delivery pressure for commercial and residential services is 0.25 PSIG (4 oz. per

sq. inch or 7 inches Water Column) to the Meter.


35.3. Delivery Pressure Higher than Standard Delivery Pressure – “High Pressure Delivery”

35.3.A. The Commercial Load Designer must review and approve all requests for “high pressure

(higher than standard pressure) delivery”. 35.3.B. If necessary (i.e. due to equipment fuel gas requirements, process loads, or other design

requirements), LG&E may have higher delivery pressures available. 35.3.C. Higher than standard delivery pressures or “high pressure” deliveries are limited by the

characteristics and operating restraints for the particular medium pressure main to the Customer meter.

35.3.D. Commercial customers must demonstrate an operational need for “higher than standard

pressure” delivery; delivery pressure higher than the standard will not be supplied to the Customer to compensate for inadequately sized houseline piping.

35.3.E. Customers with higher delivery pressures will be billed with a correction factor to account

for the actual gas used during the billing period. Special requirements may exist for “higher than standard pressure” deliveries.

35.3.F. Reference the House Line section of this handbook for details on materials and joining

pipe at higher than standard delivery pressure. 35.3.G. The following delivery pressures may be available (note discussion above):

• 2 PSIG, 2.5 PSIG, 5 PSIG, 10 PSIG, 15 PSIG • Consult Gas Commercial Load Designer for pressure availability above 4 oz.


GAS METER LOOP MATERIAL, JOINING, SUPPORT, & PROTECTION 36. Meter Loop Assemblies

36.1. Meter Loop Assembly Fabrication

36.1.A. General

• Each meter loop must be designed and installed to limit stresses on the connecting piping, meter, and regulator.

• Customer house line piping is not permitted to be connected on the service line side of

the meter.

36.1.B. Configuration

• Meter loops should be fabricated such that the meter inlet piping is on the left, as the meter is read, and the outlet piping (house line) is on the right.

36.1.C. Multiple Meters

• Multiple meters shall be fed by a common meter manifold. • Meter inlet piping shall not be constructed from the bypass piping of an existing meter. • Multiple meter installations serving residential and small commercial Customers using

standard meters (175 and 250 CFH meters) are required to be constructed with prefabricated meter loop assemblies to the greatest extent practical. See Drawing No. GCS 30-20-206, Typical Multiple Meter Installation Prefabricated Meter Loops, for a multiple meter installation using prefabricated meter loop assemblies.

• The house line side of each meter loop in a multiple meter setting must be permanently

tagged with the identity of the unit or equipment served by that meter. • Meter manifolds serving multiple commercial meters must have a master meter valve.

36.1.D. Prefabricated Meter Loop Assemblies

• Prefabricated meter loop assemblies are required for service to Customers utilizing

standard meters up to 250 CFH nominal capacity (i.e., at 0.5” W.C. differential) whenever total demand and character of demand permit.

For single meter installations reference the following drawings for piping details of standard house meters using prefabricated meter assemblies:

1. GCS 30-20-201, 1” Prefabricated meter Loop, 2. GCS 30-30-201, Low Pressure Meterset Assembly, 3. GCS 30-30-202, Medium Pressure Meterset Assembly 1 NPS x 20 LT

with Regulator, 4. GCS 30-30-203, Elevated Pressure Meterset Assembly 1 NPS x 20 LT

with Regulator, • For maximum gas demand of over 300,000 BTUH served from a low pressure (i.e.,

0.25 psig) system, or where a bypass operation must be performed (such as for


maintenance to a meter or pressure regulator) without interruption of normal operation, the prefabricated meter loop should not be used; field fabricated meter loops should be used instead.

36.1.E. Field Fabricated Meter Loop Assemblies

• Use of welded service manifolds is encouraged to reduce the number of threaded pipe

connections. Threaded pipe connections are prone to leaks over time. • Meter loop piping serving rotary meters is required to be joined by welds. Line size valve

and regulator connections should be flanged. • For maximum gas demand of over 300,000 BTUH served from a low pressure (i.e.,

0.25 psig) system though a one inch (1”) meter, a prefabricated meter loop shall be used if external bypass is not required. If an external bypass is required, a meter loop may be fabricated from standard pipe and fittings per Drawing No. GCS 30-20-204, 1” Meter Loop Field Fabricated.

• For any application in which an external bypass is required, and for any application

requiring a meter of 375 CFH or more nominal capacity, the meter loop assembly will need to be fabricated using standard pipe and fittings. See Drawings Nos. GCS 30-20-301, 1” Meter Loop with By-pass, and GCS 30-20-302, 1½ Meter Loop with By-pass.

• Drawings will be referenced and/or furnished by the Gas Commercial Load Designer

for rotary meter installations and other field fabricated meter piping configurations when applicable.

• Meter loops for meters of 375 CFH or larger capacity in a multiple meter setting will

need to be fabricated using standard pipe and fittings. See Drawing No. GCS 30–20-001 for meter piping details for a typical multiple meter installation using standard fittings.

• The Company will furnish custom drawings when necessary for multiple meter

installations. 36.2. Meter Loop Gaskets

36.2.A. Do not use full face gaskets or semi-metallic spiral wound gaskets on the meter

loop. • It is the experience of LG&E SR&O that full face gaskets are prone to leakage and are

more difficult to replace than standard ring gaskets.

36.2.B. Gaskets must be non-asbestos, and listed for natural gas service • Gaskets consisting of a fiber blend with a nitrile rubber binder are commonly used on

commercial meter loops.

1. Other gasket materials are permissible, but must be approved by LG&E prior to installation.

36.3. Meter Loop Welding

36.3.A. Where welded meter loops are required, the loops must conform with the following:

• Welded meter loops must be welded by a qualified welder using qualified welding

procedures in accordance with the requirements of API Standard 1104, ASME Boiler and Pressure Vessel Code Section IX, or 49 CFR Part 192 Appendix C.


36.4. Meter Loop Assemblies Material Specifications

36.4.A. Only steel pipe and steel or malleable iron fittings shall be used for meter loop construction. 36.4.B. Street elbows and close nipples are prohibited for construction of meter loops. 36.4.C. Bushings shall not be used for size reduction on meter loop or service riser piping; however,

they may be used for reduction of two or more sizes for test connections or gauge points. 36.4.D. Unions may be used if located downstream of the master valve or manifold valve. 36.4.E. Threaded pipe must be at least schedule 40 wall thickness.

• All threads on pipe and fittings holding gas pressure must be standard taper in

accordance with specification ANSI/ASME B1.20.1, Standard for Pipe Threads, General Purpose.

approval by LG&E.


36.5. Meter Loop Valve Requirements

36.5.A. Master Valve Requirements

• Master valves are required for installations with two or more meters.

1. If all meters are served from a single manifold, one valve shall be

provided ahead of that manifold, preferably at the top of the service riser. See Drawing GCS 30-10-002, Master Valve Requirements for Multiple Meter Installations, Figures A & B.

• Master valves for two or more manifolds.

1. If meters are served from more than one manifold, a master valve is

required for each manifold. See Drawing GCS 30-10-002, Master Valve Requirements for Multiple Meter Installations, Figure C.

36.5.B. Bypass Valve Requirements

• Bypass valves are required on meter loops one and a half inches (1-1/2”) and

larger, and on some field fabricated one inch (1”) meter loops, in order to prevent major inconvenience or interruption of commercial process which would result from the shutting off of gas for meter change operations.

1. Generally, any meter loop that has a meter with a capacity of 425,000

BTU/H or greater at one half inch (½”) water differential will have a bypass. See Drawings No. GCS 30-20-301, 1” Meter Loop with By-pass, and GCS 30-20-302, 1½” Meter Loop with By-pass.

36.5.C. Inlet Side (or Service Side) of Meter Loop

1. Customers with certain pressure requirements. 2. Customers using LP (Propane) as a backup or alternate fuel.

• The Customer is responsible for installation and maintenance of the check valve.

36.6. Meter Loop Supports

36.6.A. The house line or outlet side of the meter loop must be rigidly supported using split ring or

equivalent clamps if vertical or horizontal piping exceeds eight inches (8”) before entering the building.

36.6.B. All free standing supports must be constructed of steel beams or steel piping. 36.6.C. All supports should be insulated from pipe with non-conductive material such as fiberglass

sleeves or rubber shields. 36.6.D. When supplying gas to a corrugated stainless steel tubing (CSST) house piping

system, the transition must be made at an approved termination fitting securely anchored to the outside wall.

• A plastic sleeve must surround the tubing if passing through concrete or masonry. • A split ring clamp, or equivalent, will be required if the pipe thread size and mounting

configuration of the termination fitting is not sufficient to rigidly support the meter. See Drawing No. GCS 30-20-002, CSST House Piping.

36.7. Atmospheric Corrosion Protection - Painting

36.7.A. General

• Meter loop piping installed outdoors or in other locations that are subject to atmospheric corrosion must be properly coated or otherwise protected from atmospheric corrosion. A good quality paint intended for exterior use on metal, applied to a properly prepared surface, may be used.

36.7.B. Valve Painting

• LG&E recommends painting meter inlet master valve(s) the color red to assist

emergency services in identification of master valve. • The remaining isolation valves should be painted a non-red color, preferably a non-

reflective gray.

37. Electrical Bonding/Grounding of Gas Pipe

37.1. General 37.1.A. Electrical bonding or ground of natural gas service piping endangers the safety of the

Customer, the Public, and the Company. 37.1.B. Electrical bonding to the service, service riser, and/or meter(s) is prohibited.


37.1.C. Using gas service piping or meter loop, as a grounding or current carrying conductor is prohibited.

38. Meter Protection

B1.20.1. • Pipe joint compound or tape shall be applied to the male threads only. • All thread nipples (straight non-tapered threads) shall not be used. • Close nipples (tapered threads not separated by a shoulder) and malleable iron

bushings are not recommended. If used, malleable iron bushings should be limited to low stress applications with a reduction of two or more nominal pipe sizes.

49.3.B. Joining

• Steel pipe and fittings may be joined by welding, threading, or bolted flanges (subject

to the requirements below). Compression fittings using gasket materials which are subject to failure when exposed to heat from a fire shall not be used on inside locations.

• Welded joints should be made using established procedures and welders qualified

under specification API 1104, Standard for Welding Pipelines and Related Facilities; AWS B2.1, Standard for Welding Procedure and Performance Qualification; or the ASME Boiler and Pressure Code, Section IX.


49.3.C. Prohibited Locations

• Underground

1. Steel pipe may not be buried beneath buildings, or be in contact with the

ground beneath buildings, unless fully encased in a gas tight conduit. The Gas Operations Center in your area must be consulted for specific requirements.

49.4. Polyethylene (Plastic) House Line Pipe

49.4.A. Specifications

• Polyethylene pipe must comply with ASTM D-2513. The same material grades that

are acceptable for service line installations are acceptable for house line piping. Polyethylene gas pipe may be used only outside of buildings and beneath the ground.

• An insulated copper tracing wire shall be installed adjacent to the polyethylene pipe

with the ends terminating above ground at each end. Contact between the tracing wire and the polyethylene pipe should be avoided.

49.4.B. Joining

• Joints may be made in polyethylene plastic using approved mechanical fittings or heat

fusion. • Properly trained and qualified installers should follow qualified written joining

procedures. • All transitions to steel pipe must be outside. Transitions may be made using service

head adapters or anodeless risers in the same manner and type as used for service risers, or transition to mill coated and cathodically protected house lines may be made directly below ground. Refer to Drawing No. GCS 80-20-302, Polyethylene to Steel Transition for Underground House Line.

49.4.C. Prohibited Locations

• Polyethylene (plastic) pipe shall not extend into a building or be installed inside to

serve appliances; polyethylene (plastic) pipe shall only be installed outside for an underground house line application.

• Polyethylene (plastic) pipe may not be buried beneath buildings, or be in contact with

the ground beneath buildings, unless fully encased in a gas tight sleeve of protected steel pipe vented to the outside of the building. The Gas Operations Center in your area must be consulted for specific requirements.

49.5. Corrugated Stainless Steel Tubing (CSST) System House Line Pipe

49.5.A. General

• It is the responsibility of the customer and/or customer representatives to ensure that

CSST systems are installed according to the manufacturer’s instructions and comply with all applicable codes.


49.5.B. Specifications • Corrugated stainless steel tubing (CSST) systems must be tested, listed, and installed

in accordance with ANSI LC-1/CSA 6.26, Fuel Gas Piping Systems Using Corrugated Stainless Steel Tubing.

• CSST may be used for installation of new house line systems or for addition to

existing systems. 49.5.C. Joining

• Only qualified installers, trained by authorized agents for the respective brands of

CSST system, are allowed to install CSST piping systems. 49.5.D. Connections

• Connection of the CSST to the meter outlet piping must be made using a suitable

transition fitting supported by the outside building wall, such that the tubing is not exposed. See Drawing No. GCS 30-20-002, CSST House Piping, for a typical installation.

49.5.E. Labeling

• The corrugated stainless steel tubing (i.e., Wardflex, Titeflex, GasTite, TracPipe, etc.)

used on fuel gas manifolds shall be tagged and/or labeled in a fashion by plumbers so that the appliance served by the tubing is permanently and clearly marked.

49.5.F. Grounding

• NFPA 54 states that each above ground portion of a gas piping system that is likely to

become energized shall be electrically continuous and bonded to an effective ground fault current path. Gas house line piping shall be considered to be bonded when there is a continuous metal connection to appliances that are connected to the equipment grounding conductor of the circuit supplying that appliance.

• The NEC allows the appliance grounding provision to serve as the pipe grounding

provision so a separate bond wire is not generally required. However, nothing prohibits additional bonding especially if this is requirement of the CSST manufacturer.

• If additional grounding of the CSST houseline piping system is required, LG&E

recommends installing an approved grounding clamp and a bond wire from the grounding strip in the electrical panel to the nearest section of each continuous section of CSST piping. The bond wire should be sized in accordance with Table 250.66 of the NEC. The grounding connection would have to be made by a qualified electrical contractor and would be subject to an electrical permit and inspection.

• LG&E does not recommend grounding the CSST piping to a separate ground rod. This

would establish a separate independent building ground and would violate the requirements of the NEC. There is a concern about separate grounding systems and the potential to injure someone in contact with two separate grounding systems during a fault, lightning strike, etc.

49.5.G. Prohibited Locations

• CSST may not extend into the fireboxes of fireplaces designed to burn solid fuel.

CSST or fittings may not be installed in any manner or locations where they will be subjected to heat from solid fuel fires.


49.6. Copper Tubing House Line Pipe

49.6.A. Specification

• Copper tubing shall comply with standard Type K or L of ASTM B 88, Specifications

for Seamless Copper Water Tube, or ASTM B280, Specification for Seamless Copper Tube for Air Conditioning and Refrigeration Field Service.

49.6.B. Joining

• Joints in copper tubing shall be made with fittings approved by the manufacturer for

natural gas service or shall be brazed using materials with higher than 1,000 degrees Fahrenheit (1,000oF) melting point.

49.6.C. Connections

• The transition to copper from the steel or CSST must be made outside. The transition

to copper must be preceded by a valve located outside. 49.6.D. Prohibited Locations

• Copper tubing shall only be installed outside for an underground house line

application (e.g., to serve gas grills, gas lights, or other outside natural gas appliances).

• Copper tubing shall not be installed inside to serve appliances. • Copper tubing shall not be used as a service line.

50. House Line Support

50.1. General

50.1.A. Gas house line piping must be adequately supported to prevent stress on fittings, appliance

connections or meter connections; and to prevent excessive vibration or movement. 50.1.B. The maximum distances between supports are as follows:

• ½ inch pipe shall not exceed 6 feet, • ¾ inch or 1 inch pipe shall not exceed 8 feet. • 1-1/4 inch or larger pipe

1. When oriented vertically, at least one support for each floor level 2. When oriented horizontally, the distance between supports shall not exceed

10 feet. 50.2. CSST Support

50.2.A. All provisions for supporting and protecting CSST must be followed in accordance with

manufacturers’ written procedures.


51. House Line Piping Protection

51.1. Piping Through Concrete, Asphalt or Masonry

51.1.A. When the house line passes through a concrete or masonry wall, a nonmetallic sleeve must

be provided. In addition, the spaces between the pipe, sleeve, and masonry must be sealed to prevent entry of water or gas into the building. See Drawing No. GCS 20-20-006, Gas Pipe Sleeving Through Concrete or Masonry.

51.1.B. Pipe passing through masonry walls, floors, or ceilings should be encased in a sleeve of

plastic pipe. Underground piping, where installed through the outer foundation or basement wall of a building shall be encased in a protective pipe, sealed to prevent entry of gas or water.

51.2. Protection from Physical Damage

51.2.A. Means shall be provided to prevent excessive stressing of the piping where there is heavy

vehicular traffic or soil conditions are unstable and settling of piping or foundation walls could occur.

51.2.B. Any above grade copper tubing must be protected against physical damage. 51.2.C. Steel pipe installed outside and aboveground must be protected against damage from

anticipated forces.

51.2.D. CSST must be protected according to manufacturer recommendations and standard industry practices.

51.3. Corrosion Control

51.3.A. Steel

• Steel pipe buried beneath the ground must be effectively coated and cathodically

protected to prevent corrosion. Fittings and blemishes in the coating must be wrapped with a protective tape or mastic intended for this purpose. The underground portion must be electrically insulated from non-protected piping using dielectric couplings, dielectric unions, or flanges.

• Steel pipe installed outside and aboveground must be painted or otherwise coated to

prevent atmospheric corrosion. 51.3.B. Copper

• If any part of the copper tubing is buried underground, a dielectric fitting must be used

to electrically isolate the copper tubing from the steel or CSST house line piping. If the transition to steel is made underground, the steel pipe must be coated, cathodically protected, and electrically insulated from the house line piping.

• For underground copper tubing installations, the vertical portion, from approximately

six inches (6”) below grade to the transition fitting above grade, must be encased in a steel pipe or sunlight resistant plastic pipe securely mounted to the building wall. The space between the copper tube and protective sleeve shall be filled with expanding foam, or otherwise sealed at the top, to prevent entry and accumulation of rain water. Insulation must be used, if necessary, to prevent a steel casing pipe from electrically shorting the dielectric transition fitting.


HOUSE LINE INSPECTIONS, PRESSURE TESTING, & MAINTENANCE

52. House Line Pressure Test

52.1. General

52.1.A. Prior to requesting natural gas service, house line piping systems must be pressure tested

to detect the existence of leaks. 52.1.B. Each leg of piping that terminates at an appliance must have an appliance isolation valve. 52.1.C. Provisions must be made for the Company to install the Company’s pressure gauge to

verify the test pressure and conditions. 52.1.D. For the appropriate test pressure and test duration, contact the Gas Operations Center in

your area.

52.1.E. House line regulators (on systems with “high pressure” or higher than standard delivery pressures) should be isolated and bypassed during the pressure test.

52.1.F. Reference drawing GCS-40-00-01 Gas Regulator Installation Detail for Houseline Gas

Regulators Used to Serve Gas Equipment.

52.2. Installation of Paddle Blinds or “Skillets” 52.2.A. Skillets must be installed prior to a houseline pressure test. 52.2.B. Skillets are supplied by the Customer and must remain installed until the houseline

pressure test has been witnessed by LG&E. 52.2.C. After LG&E has passed the houseline pressure test, the Customer is responsible for

removing the skillets. 52.2.D. Locations:

• Skillets must be installed at the inlet and outlet of meter loop regulators. • Do not install skillets on either side of the rotary meter.

52.3. Test Pressure

52.3.A. House lines with a standard delivery pressure (7 in wc, 4 oz) must be tested at 3 PSIG. 52.3.B. House lines with a delivery pressure higher than standard delivery must be tested at 1.5

times the delivery pressure.

52.4. Duration

52.4.A. As a general rule of thumb, house lines should be tested 30 minutes for every 500 cubic

feet of pipe volume in the system.


• Contact LG&E for test pressures and duration for house piping volumes greater than 500 cubic feet.

52.4.B. House piping with a connected load of 10 MSCFH or greater shall be tested for a

minimum of 30 minutes.

52.5. Test Failures 52.5.A. Natural gas service will not be turned on to a house piping system believed to be unsafe

or leaking.

52.6. Repairs

52.6.A. Additions, repair, modification and other changes in the house piping system must be tested.

53. House Line Inspections

53.1. General

53.1.A. It is the ultimate responsibility of the building inspector, fire marshall, and/or other

jurisdictional authority to inspect house line piping installations for code compliance. 53.1.B. LG&E reserves the right to refuse to activate service to any house line that LG&E

representatives deemed unsafe, or that does not comply with the guidelines set forth in this handbook.


CORROSION PREVENTION 54. Corrosion Prevention - General Corrosion Protection Requirements

54.1. Protection for Aboveground Steel Piping

54.1.A. All aboveground steel piping, such as service riser or meter loop piping, installed outdoors

or indoors in damp locations shall be protected from atmospheric corrosion as required by state and federal pipeline safety regulations.

54.2. Protection for Underground Steel Piping

54.2.A. All underground (i.e., buried) steel piping, such as service lines, shall be mill coated and

cathodically protected as required by state and federal pipeline safety regulations. Similarly, building codes also require underground steel house lines to be coated and cathodically protected.

55. Corrosion Prevention - Coating Requirements

55.1. Specifications 55.1.A. Coating for Aboveground Applications

• A good quality paint intended for exterior use on metal is an acceptable aboveground coating.

• A rust inhibiting primer should be applied to the bare metal.

55.1.B. Coatings for Underground Applications

• Pipe 1. All steel pipe used for underground applications shall be purchased with

mill applied Fusion Bonded Epoxy (FBE) coating. Fusion Bonded Epoxy (FBE) is the only approved mill applied coating for steel piping in underground applications.

• Joints and Defects

1. At pipe joints and where defects in the pipe coating exist, the underground coatings on steel piping must be one of the approved coatings listed below. For other underground coatings, the coating must be approved by LG&E prior to its installation.

• Poly-Butyl Tape

1. The tape must have a total thickness of at least 25 mils that shall consist of a 20 mil tar based mastic or synthetic elastomer coating backed by a polyethylene film. It is applicable between the temperatures of -20°F and +130°F.

• Wax Tape (i.e., Plastic-fiber felt, saturated with a blend of petrolatum waxes, plasticizers

and corrosion inhibitors, forming a tape wrapper).


55.2. Pipe Surface Preparation and Coating Installation

55.2.A. Aboveground Piping

• Clean the piping surface of all dirt, oil, grease, moisture and other foreign matter. Oil

and grease should be cleaned using a cleaning solvent. • Remove all paint that is not tightly adhered. • Remove rust and loose mill scale. Power tool cleaning is recommended. However,

hand tool cleaning (i.e., wire brushing) is acceptable. Use a cleaning solvent as required to ensure a clean piping surface.

• Paint the piping surface with an acceptable aboveground coating. • The proper protective clothing, gloves and mask should be worn during the surface

preparation and coating installation process.

55.3. Underground Piping at Joints and for Defects in Coatings

55.3.A. Poly-Butyl Tape

• For defects in the coating, remove all damaged coating to a point where it is firmly bonded to the pipe.

• Clean the piping surface (i.e., the welded joints and the defects in the coating) of all dirt,

oil, grease, moisture and other foreign matter. Oil and grease should be cleaned using a cleaning solvent.

• Remove all rust, paint, and loose mill scale. Power tool cleaning is recommended.

However, hand tool cleaning (i.e., wire brushing) is acceptable. Use a cleaning solvent as required to ensure a clean piping surface.

• File or grind smooth all sharp edges or burns to prevent protrusion through the Poly-

Butyl tape.

• Apply a thin uniform coating of primer to the clean piping surface and to the mill coated piping surfaces within the area to be wrapped. The primer used shall be compatible with the coating. The piping surface must be moisture free prior to the priming procedure and remain moisture free throughout application of the Poly-Butyl tape.

• Allow primed piping surface to dry to a “tacky” stage before application of the Poly-Butyl

tape.

• Apply the Poly-Butyl tape over the weld joint or defect area by using a cigarette wrap. A cigarette wrap consists of using pre-cut strips of Poly-Butyl tape equal in length to the circumference of the pipe plus a minimum of four inches (4”).

• Apply the Poly-Butyl tape over the entire area (including the weld joint) to be wrapped

by spirally wrapping the Poly-Butyl tape around the pipe using a continuous 50% overlap of tape. The Poly-Butyl tape should be applied under tension. However, the last turn should be applied without tension. The tension in wrapping should be enough to obtain conformability to the surface being coated. The Poly-Butyl tape should then be cut on the downside of the turn and pressed into position.

• For questions or additional guidance involving the surface preparation and/or the

installation of Poly-Butyl tape, contact the Gas Operations Center in your area.


55.3.B. Wax Tape

• For defects in the coating, remove all damaged coating to a point where it is firmly bonded to the pipe.

• Clean the piping surface (i.e., the welded joints and the defects in the coating) of all dirt,

oil, grease, moisture and other foreign matter. Oil and grease should be cleaned using a cleaning solvent.

• Remove all rust, paint, and loose mill scale. Power tool cleaning is recommended.

However, hand tool cleaning (i.e., wire brushing) is acceptable. Use a cleaning solvent as required to ensure a clean piping surface.

• File or grind smooth all sharp edges or burns to prevent protrusion through the

underground coating. • Apply a thin uniform coating of primer to the clean piping surface and to the mill coated

piping surfaces within the area to be wrapped. The primer used shall be compatible with the coating. While it is preferred that the piping surface be moisture free prior to the priming procedure, a damp or wet surface is tolerable when applying wax primer and tape. Where moisture is present, rub and press primer into the piping surface, displacing the moisture and ensuring that the primer adheres to the piping surface.

• Apply the wax tape by spirally wrapping the wax tape around the pipe using a 25%

overlap (e.g., using a four inch (4”) inch wax tape, a one inch (1”) overlap is required). Press the wax tape into place making sure that no air pockets exist and that the wax tape is in contact with the piping surface. Press and smooth out the lap seams to ensure that the laps are sealed.

• For questions or additional guidance involving the surface preparation and/or the

installation of wax tape, contact the Gas Operations Center in your area.

55.3.C. Epoxy Coating

• Contact the Commercial Load Designer for epoxy specifications. 55.4. Coating Placement

55.4.A. Underground mill applied coating shall extend, at a minimum, six inches (6”) above grade on

any steel piping that enters or leaves the ground. 55.5. Coating Damage Prevention

55.5.A. Care should be exercised in the handling of coated pipe. 55.5.B. The bottom of the ditch must be free of rocks or foreign objects that may damage the

coating. In addition, backfill shall be free of rocks or debris that may damage the coating. For more detail on backfill and trench bottom conditions, refer to Section 3.10.2 a. – Backfill and Trench Bottom Requirements.

56. Corrosion Prevention - Electrical Isolation

56.1. General

56.1.A. In order for cathodic protection to be effective, all protected pipe must be electrically

separated from any electrically grounded metallic structure or piping.


56.1.B. Dielectric couplings, dielectric unions, or dielectric flanges may be used at each point where the protected piping extends out of or into the ground.

57. Corrosion Prevention - Anodes

57.1. General

57.1.A. Cathodic protection can normally be provided to the coated and electrically isolated

underground steel piping by means of a magnesium anode. 57.1.B. Magnesium anodes have an insulated lead wire that must be electrically attached to the

protected piping by thermite welding, brazing, or with an approved mechanical grounding clamp.

57.1.C. The connection to the piping must be coated with approved mastic or with tape and primer

in the same manner as a joint or defect in the coating. 57.2. Anode Spacing

57.2.A. For maximum effectiveness, one five pound (5 lbs) standard potential magnesium anode

should be used for each 50 foot (50’) section of underground steel piping. 57.2.B. To the extent practical, the anodes should be evenly spaced over the length of the piping

being protected. 57.3. Anode Installation

57.3.A. Anodes should be installed vertically at least three feet (3’) away from the piping with the top

of the anode even with or lower than the elevation of the buried piping. See Drawing No. GCS 50-20-801, Vertical Installation Anode and Test Station, for recommended anode installation method.


SPECIAL NOTICES 58. Notice Regarding the Installation of Gas Fired Electric Generators

58.1. General 58.1.A. In many cases, the installation of gas fired generators on an existing residential houseline

will require a delivery pressure increase to higher than standard delivery pressure. Not all gas systems will be able to support an increase in customer delivery pressure (reference definitions of Low and Elevated Pressure Systems).

58.1.B. Customers should contact the Commercial Load Designer to determine if the system can

support the generator load.

58.2. Installation Requirements

58.2.A. Reference manufacturer’s recommendations for installing house line regulators.
