3.0 GENERAL REQUIREMENTS3.1 Design Considerations

3.1.1 Unless otherwise noted in the specifications, all pressures and temperatures

referred to shall be considered Design Conditions. Design Conditions shall be as defined

in Doc. No....

3.1.2 Piping component wall thicknesses are based on pressure design thickness,

taking into account the specified corrosion allowance and any permitted manufacturer

under tolerance. Piping component wall thickness does not include additional thickness

that may be required to compensate for design considerations such as thermal loads

due to restraints, live loads, hydraulic shock, loads on underground pipe, or loads or

forces from other sources. Additional loads will need to be considered in the design of

piping systems.

3.1.3 Unless otherwise indicated in the specifications, piping components are specified

to be adequate for the full flange rating of the pressure class.

3.2 Line Class Notes

3.2.1 Each pipe specification contains specific numbered notes (in parenthesis) that

pertain to one individual component or to a group of components, as well as a list of

additional requirements that pertain to the entire specification.

Page 5: ENGINEERING STANDARD- Standard Piping Material Specification

3.2.2 Line class notes are provided in page 4 of this Standard. The information

contained in these notes shall be read and adhered to ensure compliance with the line

class specification.

3.3 Item Descriptions

3.3.1 The item descriptions on the individual line class are abbreviated, and may be

used for purchasing the item with the exception of Valves. Abbreviations are contained

in page 4 of this Standard.

3.2.2 The complete purchase description for Valves is contained in the Valve

specifications, and shall be followed to ensure compliance with the pipe specifications.

4.0 SPECIFIC REQUIREMENTS4.1 Pipe

4.1.1 Welded pipe shall not be substituted for seamless pipe. Seamless pipe may be

substituted for welded pipe in all services, sizes and materials.

4.1.2 Where "CALC" is specified for piping material wall thickness, the wall thickness

shall be calculated in accordance with the applicable ASME B31 Code.

4.1.3 Stainless steel, electric fusion welded (EFW) pipe (ASTM A 358) may be

substituted for ASTM A 312 EFW pipe for sizes 14 in. NPS and above.

4.1.4 Carbon steel seamless pipe, ASTM A 106B, may be substituted for ASTM A 53B,

Type S, and seamless pipe in all sizes.

4.1.5 Where joint factors are specified for pipe, these factors shall be taken as

minimum values. Use of pipe with joint factors in excess of these values is acceptable. If

pipe manufactured with a higher joint factor than listed on the specification is used, the

minimum joint factor listed on the specification shall be used when calculating wall

thicknesses of the pipe.

4.1.6 Double Submerged Arc Welded (DSAW) pipe shall be used for all EFW stainless

steel pipes. If DSAW pipe is not available, EFW pipe with a single butt joint having a joint

factor of 0.80 shall be used for 8 in. NPS and smaller.

4.2 Fittings

4.2.1 Welded fittings shall not be substituted for seamless fittings. Seamless fittings

may be substituted for welded fittings in all services, sizes and materials.

4.2.2 Dimensions of all fittings shall be in accordance with the industry standard

referenced on the individual specification.

4.2.3 Buttweld fittings shall have a wall thickness to match the wall thickness of the

adjoining pipe. Fittings of commercially available wall thickness shall be used even

though the fitting may have a slightly larger wall thickness than the adjoining pipe. The

ends of the fitting shall be taper bored if the thickness of the fittings exceeds that of the

pipe by more than 1/16 in. (1.6 mm). Taper boring shall not result in an infringement on

the minimum wall thickness.

Page 6: ENGINEERING STANDARD- Standard Piping Material Specification

4.2.4 Long radius elbows are required for all buttweld elbows. Short radius elbows shall

only be used with "Client" approval.

4.2.5 Use of Lokring® Fittings

LOKRING® fittings are generally recognized in the industry as a robust pressure

containing device that can be easily and quickly installed without a hot work permit.

These features can be highly attractive when considering the installation cost. However,

there is limited experience within "Client" on the overall long term performance for

these fittings, so the potential for long term reliability and maintenance issues must be

considered, such as inspection limitations and the potential for crevice corrosion, water

freeze damage and stress corrosion cracking due to the inherent crevice between

components and the high sealing stresses. For these reasons LOKRING fittings are

considered an acceptable alternative for use in pipe specifications provided all the

limitations described below have been met:

1. Must be approved for the intended service by the local jurisdiction or governing

body for pressure equipment. (Note: ASME B31 proof testing requirements have

been satisfied.)

2. The fittings are used in Category D (as defined in Doc. No...) or utility services as

follows:

Air, Water, Nitrogen (Outdoor Service Only) and Low pressure steam and

condensate service with a maximum design pressure of 200 PSIG.

3. The applicable pipe specification allows the use of Socket Weld construction for

the services described in item 2 above.

4. Installation shall be only for Carbon Steel piping systems up to 500°F (260°C) and

Stainless Steel piping systems up to 120°F (49°C).

5. Sizes up to and including 3 in. NPS.

6. Manufacturer trained and certified personnel must perform the installation

utilizing manufacturer approved tool kits and installation procedures. Consult

LOKRING® for guidance: www.lokring.com.

7. These fittings shall not be installed in piping systems which historically have

shown susceptibility to crevice corrosion.

8. No installations shall be made in service applications with high pulsation or

vibration forces.

9. No installation in any piping systems that require post weld heat treatment.

10.Fittings shall be grit blasted and painted in accordance to Doc. No....

11.Fittings operating below 300°F (149°C) shall be sealed with a temperature

resistant silicone caulking to prevent the ingress of water.

12.After installation, perform 100% visual inspection to verify the NOGO gage

markings are indicating proper installation (marking partially covered), the fitting

Page 7: ENGINEERING STANDARD- Standard Piping Material Specification

body protrudes from underneath the swage ring, and remaining gaps are

acceptable per the LOKRING® installation procedure.

4.3 Flanges

4.3.1 Dimensions and surface finishes of all flanges shall be in accordance with the

industry standard referenced on the individual specification.

4.3.2 Buttweld flanges shall have a wall thickness to match the wall thickness of the

adjoining pipe. Flanges of commercially available wall thickness shall be used even

though the flange may have a slightly larger wall thickness than the adjoining pipe. The

end of the flange shall be tapering bored if the thickness of the flange exceeds that of

the pipe by more than 1/16 in. (1.6 mm). Taper boring shall not result in an

infringement on the minimum wall thickness.

4.3.3 Orifice flanges shall be Class 300 minimum. Orifice flanges shall be ordered in

pairs and shall have Socketweld taps. Class 150 utility services, specifications PLC... and

PLC..., may use threaded orifice taps.

flange with a full-face gasket shall be used. Full-face gasket material shall be

compatible with process stream and shall be in accordance with Doc. No...

requirements.

4.3.5 When mating to cast steel flat-face flanges is required; a raised-face flange shall

be used. The gasket shall be of a type and material that meets the requirements of the

piping specification.

4.3.6 Flanges installed in acid/caustic service (as defined in Doc. No...) or other

hazardous material shall be protected with a flange safety shield when a potential for

exposure to personnel and/or equipment exists.

4.4 Branch Connections

4.4.1 ASME B16.9 welding tees shall be used when branch connections are size on size.

Reducing tees shall be used when the branch run is one nominal size less than the

header run.

4.4.2 Except where indicated on the individual line classes, integrally reinforced branch

connections shall be used for branch runs NPS 8 and smaller.

4.4.3 Full area replacement shall be used for branch connections above NPS 8. The

reinforcing pad thickness shall equal the header thickness, and the reinforcing pad

width shall equal 1/2 the outside diameter of the branch. The material of the reinforcing
