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, prefabri-
cated polyolefin tapes 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). This standard establishes the minimum requirements for tape
coating systems used on the exterior of steel water pipelines in the potable-water
supply industry. Continuous monitoring of all application procedures for the tape
coating systems shall be performed by the constructor.
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 difficultconditions, such as those encountered in rocky areas and in construction of
underwater lines, casing pipe, and river crossings outside thc scope of ANSI/AWWA C214.
