5.5 Expansion Allowance When test pressure is applied, polyethylene or crosslinked polyethylene pipe will expand slightly due to elasticity and Poisson effects. To compensate for expansion, make-up water is added during the initial expansion phase. The amount of make-up water (expansion allowance) will vary because expansion is not linear.Air Testing HDPE forcemain - Water treatment hdpe water pipe pressure testingSep 16, 2005Your HDPE pipe supplier should have a test procedure, it will almost certainly require a pressure greater than 7psi and wil be hydrostatic. The difficulty with HDPE is that it expands as you apply the pressure test, thereby appearing as if there is a leak.DESIGN AND SELECTION OF PLASTIC PRESSURE PIPE Potable water pressure pipes are made from many different materials. The most commonly used pipe materials for municipal water systems are polyvinyl chloride (PVC), ductile iron (DI), high density polyethylene (HDPE), steel (ST) and concrete pressure pipe (CPP).

DESIGN AND SELECTION OF PLASTIC PRESSURE PIPE

Potable water pressure pipes are made from many different materials. The most commonly used pipe materials for municipal water systems are polyvinyl chloride (PVC), ductile iron (DI), high density polyethylene (HDPE), steel (ST) and concrete pressure pipe (CPP). Selecting the right pipe material and the right class of that material, requires anDISINFECTION, PRESSURE TESTING AND Pressure test The test pressure for any MDPE/HPPE pipes should be 1.5 times the pressure rating of the pipe. For example, if the pipe the customer has laid is rated at 8 bar, the test pressure should be 12 bar. If the pipe is rated at 10 bar the test pressure will need to be 15 bar. This applies to both water mains and service pipes. The pressure test must be in accordance with the Water Research Council test Engineering Recommended Technical Testing Data hdpe water pipe pressure testingHDPE Pipe Pressure Testing Outside The Trench If specified by the engineer, pressure testing may be conducted prior to pipe installation. After the pipe has been joined, fill it with water, carefully bleed off any trapped air. Subject the pipe to a hydrostatic test pressure that is 1.5 times the system design pressure for a maximum of 3 hours.
