AWWA C219-11

This standard covers bolted, sleeve-type couplings, reducing or transition couplings, and flanged coupling adapters used to join plain-end steel and ductile-iron pipe. They may be manufactured from carbon steel, stainless steel, ductile iron, or malleable iron, and are intended for use in systems conveying water. This standard covers nominal pipe sizes from ? in. (12.5 mm) through 144 in. (3,600 mm). The purpose of this standard is to provide the minimum requirements for bolted, sleeve-type couplings for plain-end pipe, including requirements for materials, design, testing and inspection, installation, and shipping.
