AWWA C222-2008 钢制水管和配件的内部和外部用聚氨酯涂层

This standard sets minimum requirements for shop- and field-applied polyure- thane interior linings and exterior coatings used in the water supply industry. These coatings are used for steel water pipe, special sections, welded joints, connections, or fittings for steel water pipelines installed underground or underwater operating under normal conditions. 1.1.1 Coating andliningsysterns. Unless otherwise specified by the pur- chaser, the lining and coating systems shall consist of an ASTM D16 Type V thermoset, aromatic polyurethane plastic polymer that is the reaction product of diphenylmethane diisocyanate (MDI) resin and polyol resin or polyamine resin or a mixture of polyol and polyamine resins. Typically, these systems are solvent free or almost solvent free (less than 10 percent solvent by volume). They are fast setting (cure to handle in less than 30 min) and are applied in one coat direct to steel. However, there are a wide variety of polyurethane technologies available on the market that may contain up to 10 percent solvent or are slower setting that also meet the requirements of this standard. 1.1.2 Conditions not described in this standard. The coating systems described in this standard are not intended for use on pipe that will be bent after the lining or coating system has been applied. 1.1.3 Maximum temperature. AWWA steel pipe coating standards are writ- ten for and based on the service temperature of potable water. Consult the coating manufacturer for conditions and limitations. Polyurethane coating is suitable for water and wastewater pipelines operating at temperatures up to a maximum of 150℉ (66℃).
