AWWA C225-20 Fused Polyolefin Coatings for Steel Water Pipe
SKU: 43225-2020
This standard describes the materials and application of fused polyolefin coating systems for buried service. This system is applied in pipe coating plants, both portable and fixed, using coating techniques and equipment as recommended by the manufacturer. Typically, these prefabricated, polyolefin coatings are applied as a three-layer system consisting of (1) a liquid adhesive layer, (2) a corrosion-protection inner layer, and (3) a mechanical-protection outer layer.
