AWWA C214-14

This standard covers 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: liquid adhesive; corrosion-preventive tape (inner layer); and 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 done by the constructor. All AWWA pipe coating standards are intended for potable-water service. Therefore, the maximum service temperature of this coating is based on the maximum service temperature of potable water. These coating systems will perform at higher temperatures.

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.
