Rubber-Gasket Joints for Ductile- Iron Pressure Pipe and Fittings

Standard Details

This standard describes rubber-gasket joints of the following types for ductile-iron pressure pipe and ductile-iron and gray-iron fittings, valves, hydrants, and other appurtenances for potable water, raw water, nonaggressive wastewater, and reclaimed water supply service.

Mechanical Joint — The mechanical joint is designed for pipe in sizes 3 in. through 24 in. (80 mm through 600 mm), and fittings in sizes 3 in. through 64 in. (80 mm through 1600 mm).

Push-On Joint — The push-on joint is designed for pipe and fittings in sizes 3 in. through 64 in. (80 mm through 1,600 mm).

Flanged Joint — The flanged joint is designed for pipe and fittings in sizes 3 in. through 64 in. (80 mm through 1,600 mm).

Modifications to Push-On and Mechanical Joints — Modifications to the designs shown in this standard, including but not limited to segmented or special glands and split sleeves, are permissible as long as the design meets the performance requirements stated in Sec. 4.7.

This standard can be referenced in purchase documents for rubber-gasket joints for ductile-iron pressure pipe and ductile-iron and gray-iron fittings. The stipulations of this standard apply when this document has been referenced and only to rubber-gasket joints for ductile-iron pressure pipe and ductile-iron and gray-iron fittings. For applications involving potentially aggressive waters and wastewaters, consult the pipe manufacturer for suitable elastomers.
