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) 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. Major revisions to this edition of the standard are too numerous to list here and can be found in the Foreword section of the standard.
