![]() Series 1 is a metric size range and Series 2 is compatible with the outside diameter of Australian cast and ductile iron pipes. The following Australian Standards specify requirements for PVC pressure pipes AS/NZS 1477 – PVC pipes and fittings for pressure applicationsĪS/NZS 1477 covers two size ranges of PVC-U pipes. Pipes are supplied with an integral socket for either solvent cement or rubber ring 1 jointing or as plain-ended pipes for jointing with couplings. The standard effective length of PVC pipes is 6m although other lengths, up to 12m, may also be available. ![]() ![]() Special purpose colours for specific applications may also be used, such as purple for recycled water.įor a given diameter series and nominal size, the mean outside diameter is specified and the wall thickness increases with increasing pressure rating. These are identified in the marking on the pipe and sometimes by colour. Australian Standards generally cover more than one size range with different outside diameters. Pipes are designated by their nominal size (DN) and their nominal pressure rating or class at 20☌ (PN). Australian Standards for PVC pressure pipes cover composition, dimensions, performance and marking requirements for pipes, fittings and joints.
