ANSI/AWWA C224-2006 PDF

Scope: This standard describes polyamide (Nylon-II-based) coating systems for interior and exterior of steel pipe, connections, fittings, and special sections that are used in water-handling equipment that is installed aboveground, belowground, or underwater. Polyamide coating systems are thermoplastic and are ordinarily applied in a shop or manufacturing facility. 1.1.1 M/n/mum pipe diameter. The minimum pipe diameter for application of the polyamide coating system to the interior of a pipe shall be the diameter that permits effective inspection and repair. For joints of pipe, this minimum diameter is ordinarily 24 in. (600mm). For pipe diameters less than 24 in. (600 mm), the coating manufacturer shall be consulted regarding methods of inspection and repair. 1.1.2 Maximum temperature. AWWA pipe coating standards arc written for and based on the service temperature of potable water. The maximum temperature at which a polyamide coating system can be used shall be specified by the manufacturer.
