AWWA C909-09 Molecularly Oriented Polyvinyl Chloride (PVCO) Pressure Pipe, 4 In. Through 24 In. (100 mm Through 600 mm) for Water, Wastewater, and Reclaimed Water Service (PDF)
SKU: STC_0071572-PDF
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 (OD) conform to those established for CI-equivalent ODs (CIOD). Pressure classes range from 165 psi to 305 psi (1,140 kPa to 2,100 kPa) in sizes 4 in. through 24 in. (100 mm through 600 mm).
Description
The major revisions to this edition include the following: the factor of safety was revised from 2.5 to 2.0; the built-in surge allowance was eliminated; the pressure classes were revised from 100, 150, and 200 psi (690, 950, and 1,380 kPa) to 165, 235, and 305 psi (1,140, 1,620, and 2,100 kPa), respectively; treatment of surge pressures was expanded to include occasional (emergency) surge and recurring (cyclic) surge; and, wastewater and reclaimed water were added to the standard's scope.
