Pvc schedule 40 pipe fittings.
Polyvinyl chloride pvc schedule 40 pressure fittings are used for potable water chilled water irrigation golf course construction and pool spa applications.
The pressure ratings given are for water non shock 73 f.
As the temperature of the pvc increases the pressure that the pvc can withstand will decrease.
Be aware that schedule 40 pvc pipe does have a lower pressure rating therefore using schedule 40 parts on a primarily schedule 80 pipe system is not recommended.
Australian standards generally cover more than one size range with different outside diameters.
This system is intended for pressure applications where the operating temperature will not exceed 140 f.
Australian standards for pvc pressure pipes cover composition dimensions performance and marking requirements for pipes fittings and joints.
Pvc pressure pipe standards.
Schedule 40 and schedule 80 pvc pipe and fittings have identical od outer diameters and can be used interchangeably if needed.
Pvc conduit isn t approved to use in plumbing applications because it isn t pressure tested making the chances of leaking higher.
