DWV Pipe and Fittings
Product Dimensions

DWV Pipe

Pipes are supplied in effective lengths of 6 metres or 3 metres. Total pipe length = Effective Length + Insertion Depth.
 
Pipes are supplied with either rubber ring or solvent weld jointing systems, in classes SN6 and SN10 (DN100) and SN4 and SN8 (= > DN150).   Pipes = < DN80 are not defined by stiffness but by minimum wall thickness.
 
Pipes are specified in terms of stiffness classes measured in a standard test. The new classes are not exactly the same as the earlier classification scheme (Class SH and Class SEH) but are similar.
 
Class SN4 and Class SN6 are considered to be suitable for plumbing and domestic use, effectively replacing Class SH.
 
Class SN8 and Class SN10 are suitable for general municipal drainage, deeper burial and similar applications where higher pipe stiffness is required to minimise deflection of the installed pipes due to the load imposed by the back fill or surcharge or to poor installation practice. These pipes have effectively replaced Class SEH pipes.
