scope:
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 ANSI*/AWWA C203, ANSI/AWWA C210, ANSI/AWWA C213, ANSI/AWWA C214, ANSI/AWWA C215, 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 has been applied directly onto the bare steel pipe.
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.
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.
Purpose
The purpose of this standard is to provide the minimum performance requirements for tape coatings, including material, application, inspection, testing, marking, and packaging requirements.
