Machine-Applied Polyolefin Tape Coatings for Steel Water Pipe

Standard Details

This standard describes the materials and application of prefabricated polyolefin 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, tape coatings are applied as a three-layer system consisting of (1) liquid adhesive, (2) corrosion-preventive tape (inner layer), and (3) mechanical-protective tape (outer layer). It establishes the minimum requirements for tape coating systems used on the exterior of steel water pipes. Continuous monitoring of application procedures for the tape coating systems shall be performed by the applicator. 1.1.1 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. 1.1.2 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.
