AWWA C909-22 Molecularly Oriented Polyvinyl Chloride (PVCO) Pressure Pipe, 4 In. (100 mm) and Larger
SKU: 43909-2022
The purpose of this standard is to provide purchasers, manufacturers, and suppliers with the minimum requirements for wet-barrel fire hydrants for fire-protection service, including materials, design, inspection, testing, marking, and shipping requirements.
Description
This standard pertains to molecularly oriented polyvinyl chloride (PVCO) pressure pipe that is manufactured from starting stock pipe made from ASTM D1784 cell class 12454 material. The starting stock materials are then oriented through circumferential expansion to provide a hydrostatic design basis (HDB) of 7,100 psi (49.0 MPa). The pipe is primarily intended for use in transporting potable water, wastewater, and reclaimed water in buried installations. Pipe outside diameters (ODs) conforms to those established for ductile-iron (DI)-equivalent ODs (DIODs). Pressure classes range from 165 psi to 305 psi (1,140 kPa to 2,100 kPa) in sizes 4 in. (100 mm) and larger.
