Tape Coatings for Steel Water Pipe
|Publication Date:||19 January 2014|
This standard describes the materials and application of tape
coating systems in coating plants at fixed sites using coating
techniques and equipment as recommended by the tape coating
manufacturer. For normal construction considerations, prefabricated
polyolefin tapes are applied as a three-layer system consisting of
(1) liquid adhesive, (2) corrosion-preventive
Maximum temperatures. AWWA pipe coating standards are written for and based on the service temperature of potable water. These coating systems have performed at higher temperatures. Consult the coating manufacturer for conditions and limitations.
Conditions not described in this standard. This standard does not describe the additional materials and procedures that may be required for difficult conditions, such as those encountered in rocky areas or where soil conditions are known to be severe and in construction of underwater lines, casing pipe, and river crossings outside the scope of ANSI/AWWA C214. The manufacturer should be consulted for specific recommendations when these conditions exist.
The purpose of this standard is to provide the minimum performance requirements for tape coating systems for the exterior of steel water pipelines, including system components, application, inspection, testing, and marking and packaging requirements.
