Standard Methods for the Examination of Water and Wastewater
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 tape (inner layer), and (3) mechanicalprotective tape (outer layer). This standard establishes the minimum requirements for tape coating systems used on the exterior of steel water pipe in the potable-water supply industry. Continuous monitoring of all application procedures for the tape coating systems shall be performed by the constructor.

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.
