AWWA Comment Period on ANSI/AWWA C209 -Tape Coatings for Steel Water Pipe and Fittings


AWWA solicits public comments on all proposed new AWWA Standards, and on all proposed revisions, reaffirmations, or withdrawals of existing AWWA Standards. The referenced standards project is being considered for approval and the publication of this notice begins the 45-day public comment period for AWWA and ANSI. An electronic public review copy of the proposed standard can be obtained for review during the comment period by emailing Comments must be submitted in writing to the AWWA contact listed below no later than the last day of the comment period specified herein. Such comments shall be specific to the section(s) of the standard under review and include sufficient detail so as to enable the reader to understand the commenter's position, concerns and suggested alternative language, if appropriate. 

AWWA Comment Period closes on 6/24/19.

The review copy will be edited for publication and may also be revised as appropriate based on any comments received during the public comment period. Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes. 

Final publication of the standard may take several months. When it is available, a notice will be published in the official notice section of Journal - American Water Works Association. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal - American Water Works Association. 

This standard describes protective coatings that consist of liquid adhesives and tapes and their applications to steel water pipe and fittings to be used for underground and underwater pipelines. Tape coatings conforming to this standard may be field- or shop-applied, without the use of heat (i.e. not hot applied coatings),to uncoated pipe and fittings or as a joint coating to pipe and fittings protected with organic coatings, such as those described in ANSI1/AWWA C203, ANSI/AWWA C210, ANSI/AWWA C213, ANSI/AWWA C214, ANSI/AWWA C215, and ANSI/AWWA C216, ANSI/AWWA C222, ANSI/AWWA C224, ANSI/AWWA C225 and ANSI/AWWA C229. These liquid adhesives and tapes can be used for repair of ANSI/AWWA C214 machine-applied coatings in accordance with the tape manufacturer’s recommendations. These liquid adhesives and tapes are not intended for use with either exposed steel joints or sections of steel pipe where coating of cement mortar or concrete have been applied directly onto the bare steel pipe. 

1.1.1 Maximum temperatures. AWWA pipe coating standards are written for and based on the service temperature of potable water. Cold-applied tape coatings have performed at higher temperatures. Consult the coating manufacturer for conditions and limitations. 

1.1.2 Conditions not included in this standard. This standard does not include the additional materials and procedures that may be required for difficult conditions, such as those encountered in some submarine pipelines, casing pipe, river crossings, and pipelines in exceptionally rocky areas. Also, it is not intended to describe conditions of extended exposure aboveground after application. When extended periods of aboveground exposure are contemplated, the tape manufacturer should be consulted for specific recommendations. 

Major revisions made to the standard in this edition include the following: 

  1. The title of the standard was revised and the term cold applied tape removed since it is covered in the scope. 
  2. Throughout the document the term fabricated cold applied tape was replaced with tape since the scope notes that hot applied tape is not covered in C209. 
  3. Sec. 1.1 Scope was revised to better reflect the intended scope of the standard. 
  4. Sec. 2 References was updated. 
  5. The definition for applicator was added to Sec. 3. 
  6. Sec. 4.1 Equipment was moved to be consistent with other AWWA steel pipe coating standards. 
  7. Sec. 4.2 Materials and Workmanship was revised and sections on safety and personnel were added to be consistent with other AWWA steel pipe coating standards. 
  8. In Sec. 4.3.1 the sentence regarding complying with pollution control requirements was deleted. 
  9. Sec. 4.3.2 was revised to cover the inner tape and the reference to Type 1 and Type 2 tape was removed since the tape can now use either type with the same requirements. 
  10. Sec. Form, Sec. Dimensions and Sec. Thickness were deleted since the information provided was general and tapes can be supplied in various widths and roll lengths. 
  11. A new Sec. 4.3.3 on outer wrap tape was added. 
  12. Table 1 was revised to cover Prequalification Requirements for Inner Wrap Tape, and a minimum tape thickness was added. 
  13. A new Table 2 was added for Prequalification Requirements of Outer Wrap Tape (if required), and includes requirements for adhesion to inner wrap and width deviation. 
  14. A new Table 3 was added for Prequalification Requirements of the Total Coating System and includes requirements for adhesion to primed steel and cathodic protection. 
  15. Sec. 4.4 Surface preparation, was revised in an effort to begin to establish consistent language between similar AWWA steel pipe coating and lining standards where. 
  16. In Sec. 4.4.3 Methods of cleaning, the minimum required cleanliness for dry blast cleaning was changed from SSPC-SP 6 to SSPC-SP 7 and SSPC-SP 2 was added as a new minimum required cleanliness for tool cleaning. 
  17. In Sec. 4.5.1 Priming, the reference to emission regulations was removed. 
  18. In Sec. 4.5.3 Coating and wrapping, the overlap was reduced from 3 in. to 2 in. 
  19. In Sec. 5.2.4 Water vapor transmission, the test method was updated to be consistent with other AWWA steel pipe coating standards. 
  20. Sec. through Sec. were deleted from Sec. 5.5.2 Electrical continuity inspection, since this language was taken directly from NACE SP0274 which is refenced in Sec. 5.5.2 and will send the reader to the original document. 
  21. Sec. Frequency of testing was updated with more current language. 
  22. Sec. 6.2.2 Shipping, handling and storage was updated to be consistent with other AWWA steel pipe coating standards. 
  23. Sec. 6.3 Affidavit of Compliance was modified to include an affidavit for workmanship. Similar language has been added to other AWWA steel pipe coating and lining standards.
