AWWA C205-07 Cement-Mortar Protective Lining and Coating for Steel Water Pipe 4 In. (100 mm) and Larger--Shop Applied (PDF)

This standard describes the material, application, and curing of shop-applied cement-mortar protective linings and coatings for steel water pipe and fittings and field jointing of cement-mortar-lined-and-coated steel water pipe and fittings. The inside of the pipe shall receive a cement-mortar lining applied by centrifugally spinning or by a method known to provide equivalent results. The application of cement-mortar linings to miters, angles, bends, reducers, and other special sections, the shape of which precludes application by the spinning process, shall be accomplished by mechanical placement, pneumatic placement, or hand application and finished to produce a smooth, dense surface. The outside of the pipe and specials shall receive a reinforced cement-mortar coating applied by mechanical placement, pneumatic placement, or a method known to provide equivalent results. For field application of cement-mortar lining, refer to ANSI/AWWA C602, Standard for Cement-Mortar Lining of Water Pipelines in Place-4 In. (100 mm) and Larger. For the fabrication criteria for welded steel pipe, refer to ANSI/AWWA C200, Steel Water Pipe-6 In. (150 mm) and Larger. For design considerations either for welded steel pipe or for cement-mortar linings and cement-mortar coatings, refer to AWWA Manual M11, Steel Pipe-A Guide for Design and Installation.
