AWWA C209

Abstract

This standard describes protective exterior coatings that consist of coldapplied liquid adhesives and prefabricated tapes and their applications to special sections, connections, and fittings to be used for underground and underwater steel water pipelines protected with organic coatings, such as those described in ANSI*/AWWA C203, ANSI/AWWA C210, ANSI/AWWA C213, ANSI/AWWA C214, ANSI/AWWA C215, and ANSI/AWWA C216. 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 coatings of cement mortar or concrete have been applied directly onto the bare steel pipe. Tape coatings conforming to this standard may be field- or shop-applied. <br><em>Maximum temperatures</em>. 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. <br><em>Conditions not included in this standard</em>. 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
