ForewordThis foreword is for information only and is not a part of ANSI*/AWWA C223.

I. Introduction.I.A. Background. Fabricated tapping sleeves are used to provide outlets on

piping systems. They are made by several producers, and though details differ, all tapping sleeves provide similar features. They provide a means of attaching a tapping valve and tapping machine and a means of sealing onto or around the existing pipe.

I.B. History. The first edition was approved by the Board of Directors on June 16, 2002. The second edition was approved on June 24, 2007. This edition was approved on June 9, 2013.

I.C. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct and indirect drinking water additives. Other members of the original consortium included the American Water Works Association Research Foundation (AwwaRF, now Water Research Foundation) and the Conference of State Health and Environmental Managers (COSHEM). The American Water Works Association (AWWA) and the Association of State Drinking Water Administrators (ASDWA) joined later.

In the United States, authority to regulate products for use in, or in contact with, drinking water rests with individual states.† Local agencies may choose to impose requirements more stringent than those required by the state. To evaluate the health effects of products and drinking water additives from such products, state and local agencies may use various references, including

1. An advisory program formerly administered by USEPA, Office of Drinking Water, discontinued on Apr. 7, 1990.

2. Specific policies of the state or local agency.3. Two standards developed under the direction of NSF,‡ NSF/ANSI 60,

Drinking Water Treatment Chemicals—Health Effects, and NSF/ANSI 61, Drinking Water System Components—Health Effects.

* American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036.† Persons outside the United States should contact the appropriate authority having jurisdiction.‡ NSF International, 789 N. Dixboro Road, Ann Arbor, MI 48105.


x

4. Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex,* and other standards considered appropriate by the state or local agency.

Various certification organizations may be involved in certifying products in accor-dance with NSF/ANSI 61. Individual states or local agencies have authority to accept or accredit certification organizations within their jurisdiction. Accreditation of certi-fication organizations may vary from jurisdiction to jurisdiction.

Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 61 does not stipulate a maximum allowable level (MAL) of a contaminant for substances not regulated by a USEPA final maximum contaminant level (MCL). The MALs of an unspecified list of “unregulated contaminants” are based on toxicity testing guidelines (noncarcinogens) and risk characterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on the certifier.

ANSI/AWWA C223 does not address additives requirements. Users of this stan-dard should consult the appropriate state or local agency having jurisdiction in order to

1. Determine additives requirements, including applicable standards.2. Determine the status of certifications by parties offering to certify products

for contact with, or treatment of, drinking water.3. Determine current information on product certification.

II. Special Issues. This standard has no applicable information for this section.

III. Use of This Standard. It is the responsibility of the user of an AWWA standard to determine that the products described in that standard are suitable for use in the particular application being considered.

III.A. Purchaser Options and Alternatives. The following information should be provided by the purchaser.

1. Standard used—that is, ANSI/AWWA C223, Fabricated Steel and Stainless-Steel Tapping Sleeves, of latest revision.

2. Whether compliance with NSF/ANSI 61, Drinking Water System Components—Health Effects, is required.

3. Quantity.4. Type of pipe(s), including specification to which it is made, or specification

and tolerance of outside diameter.

* Both publications available from National Academy of Sciences, 500 Fifth Street, NW, Washington, DC 20001.

5. Nominal pipe size(s).6. Wall thickness or class of pipe.7. Type of service (i.e., line content, aboveground or belowground, etc.)8. Rated pressure, transient pressure, and test pressure.9. Operating temperature range.10. Flange specification, including dimensions for accommodating tapping

valve fit-up.11. Tapping sleeve and tapping-sleeve flange material.12. Documentation requirements.13. Requirements for test connections and postinstallation pressure testing.14. Outlet size and type (Flanged, MJ adaptor, etc.).15. Actual outside diameter (OD) of pipe, including any coatings and pipe

length available for installation of tapping sleeve (Section 3).16. Details of other federal, state or provincial, and local requirements (Sec. 4.2.1).17. Special requirements, such as coatings, gasket material, and bolting (Sec. 4.3.1).18. Inspection by the purchaser (Sec. 5.1.2).

III.B. Purchaser’s Proof Test. The purchaser may specify individual hydrostatic proof testing. If individual hydrostatic proof testing is required, the assembled fabricated tapping sleeve shall be shop tested at a maximum of 1.5 times the rated pressure. The test shall be considered successful if no leakage is detected during 1 hr of sustained pressure at this level.

III.C. Modification to Standard. Any modification of the provisions, definitions, or terminology in this standard must be provided by the purchaser.

IV. Major Revisions. Major changes made to the standard in this revision include the following:

1. Added definitions for MJ adaptor, potable water, reclaimed water, and waste-water (Section 3)

2. Updated the definitions for rated pressure and transient pressure for consis-tency (Section 3)

3. Added a minimum yield strength for bolts (Sec. 4.2.5)4. Added a reference to AWWA C228 in Sec. 4.2.3.2 and Sec. 4.3.2.

diameter by the specified tolerances and coating thickness. Whenever possible, it is recommended that a field measurement of the existing pipe be taken using a circumferential pi tape. For larger tapping sleeves, with large-diameter tapping outlets, it is sometimes advisable to provide the manufacturers with a pattern (tem-plate) that replicates the pipe surface at the area of the tap.

2. Bridging plate/armor: A means of retaining mat-style gaskets between the sections of the fabricated tapping sleeve.

3. Constructor: The party that provides the work and materials for place-ment or installation.

4. CJP: Complete joint penetration.5. Fabricated tapping sleeve: An assembly used to provide outlet(s) on an

existing pipe. See Figure 1.6. Gasket(s): An elastomeric material that provides the pressure seal(s) of

the fabricated tapping sleeve.7. Lay length: The length of the tapping sleeve as measured from the cen-

terline of the existing pipe to the face of the tapping flange.8. Manufacturer: The party that manufactures, fabricates, or produces the

materials or products.

18. Transient pressure: The purchaser-determined, short-duration maxi-mum pressure increase induced upon a system resulting from a rapid change in flow velocity. Transient pressure as defined herein represents the total pressure level achieved during the transient event and is not an incremental pressure increase above the working pressure.

19. Wastewater: A combination of the liquid and water-carried waste from residences, commercial buildings, industrial plants, and institutions, together with any groundwater, surface water, and stormwater that may be present.

SECTION 4: REQUIREMENTS

Sec. 4.1 PermeationThe selection of materials is critical for potable water, wastewater, and

reclaimed water service and distribution piping in locations where there is likeli-hood the pipe will be exposed to significant concentrations of pollutants composed of low-molecular-weight petroleum products or organic solvents or their vapors.



Documented research has shown that pipe materials (such as polyethylene and polyvinyl chloride) and elastomers, such as those used in jointing gaskets and pack-ing glands, are subject to permeation by low-molecular-weight organic solvents or petroleum products. If a potable water, wastewater, or reclaimed water pipe must pass through such a contaminated area or an area subject to contamination, con-sult with the manufacturer regarding permeation of pipe walls, jointing materials, and so on, before selecting materials for use in that area.

Sec. 4.2 Materials of Construction4.2.1 Materials. Materials shall comply with the requirements of the Safe

Drinking Water Act and other federal regulations for potable water, wastewater, and reclaimed water systems as applicable.

4.2.2 Fabricated tapping sleeve bodies. Steel fabricated tapping sleeves shall be made from material that meets or exceeds the requirements of ANSI/AWWA C200. Stainless-steel fabricated tapping sleeves shall be made from mate-rial that meets or exceeds the requirements of ANSI/AWWA C220.

4.2.3 Connections. Flanged outlets are provided on fabricated tapping sleeves. If specified by the purchaser, mechanical joint outlet connections may be provided.

4.2.3.1 Tapping flanges for steel tapping sleeves. Tapping flanges for steel fabricated tapping sleeves shall meet the requirements of ANSI/AWWA C207. Flange class shall be specified by the purchaser.

4.2.3.2 Tapping flanges for stainless-steel tapping sleeves. Tapping flanges for stainless-steel fabricated tapping sleeves shall meet the material require-ments of ASTM A240, ASTM A351/A351M, or ASTM A182. Dimensions shall be in accordance with ANSI/AWWA C207 or ANSI/AWWA C228. Flange class shall be specified by the purchaser. Other materials as specified by the purchaser may be used.

4.2.3.3 Mechanical joint outlet connections. Mechanical joint outlet connections shall be compatible with ANSI/AWWA C111/A21.11 or as specified by the purchaser. Provision for thrust restraint and angular deflection shall be con-sidered when using a mechanical joint outlet connection.

4.2.3.4 Other flanges. Other flange standards agreed on between the pur-chaser and manufacturer may be used.

4.2.4 Gaskets.4.2.4.1 Composition and physical requirements. Gaskets shall be molded

or extruded natural or synthetic rubber free of porous areas and visible defects.


8 AWWA C223-13

Reclaimed rubber shall not be used. Unless otherwise specified, gaskets shall be suitable for water service to 150°F (65°C).

4.2.4.2 Gaskets for the body of tapping sleeves. Gaskets for the body of the tapping sleeve shall meet the requirements of ASTM D2000 and have, as a mini-mum, physical properties sufficient to satisfy the design requirements of Sec. 4.3.3. Gaskets needed for the body of the tapping sleeve shall have a minimum durometer of 50 and minimum tensile strength of 800 psi. Gaskets for flange connections shall conform to ANSI/AWWA C207.

4.2.4.3 Special service requirements. Where service conditions differ from those described in Sec. 1.1, special gasket material may be required. The pur-chaser shall specify these service conditions.

4.2.5 Bolting. Similar materials shall be used for bolts, nuts, and washers (when used) to minimize the possibility of galvanic corrosion. Advice from a quali-fied corrosion engineer is recommended.

Bolts for connecting sections of the fabricated tapping sleeve shall have a minimum yield strength of 30,000 psi and meet or exceed the requirements of ASTM A307 or ASTM F568M for carbon steel or ASTM F593 or ASTM F738M for stainless steel. Nuts shall meet or exceed the requirements of ASTM A563 or ASTM A563M for carbon steel or ASTM F594 or ASTM F836M for stainless steel. Stainless-steel bolts and nuts may gall, leading to improper gasket compres-sion and leakage. When stainless-steel bolting is used, application of an antiseize compound is recommended.

4.2.6 Test connections. A test connection shall be provided unless other-wise specified by the purchaser.

Sec. 4.3 Design4.3.1 General. The sections of the fabricated tapping sleeve shall be con-

nected together on the pipe by threaded fasteners. Tightening the fasteners com-presses a gasket(s) between the fabricated tapping sleeve and pipe, thereby affecting a seal. This assembly allows the main to be tapped through the outlet, with or without interruption of service.

If required by the manufacturer, the purchaser shall provide design informa-tion, including actual pipe OD, type of pipe, wall thickness, rated pressure, type of outlet connection required, and any other special requirements.

4.3.2 Body thickness, flange gaskets, and flange class and drilling. Body thickness for steel fabricated tapping sleeves shall meet or exceed the requirements



of ANSI/AWWA C200. Body thickness for stainless-steel fabricated tapping sleeves shall meet or exceed the requirements of ANSI/AWWA C220.

Flange class, drilling dimensions, and flange gaskets shall conform to the requirements of ANSI/AWWA C207, ANSI/AWWA C228, or other applicable standard except that the inside diameter (ID) shall conform to the requirements of MSS SP-60 or as specified by the purchaser.

4.3.3 Fasteners. The size, type, and number of fasteners shall be sufficient to exert a uniform force required to develop a gasket pressure that will affect a seal to the pressure requirements.
