HDPE Pipe Expansion & Contraction As a rule of thu an HDPE pipe exhibits 0.2mm of expansion or contraction per meter of pipe length, per degree Celcius change. Therefore a 5m length of pipe will shrink 1mm per degree Celcius drop in temperature. Bear in mind that HDPE pipes are often laid in full sunlight where the surface of the pipe can

Equivalent Lengths of Pipe Fittings and - Katmar Software

Pipe (fluid conveyance) - Wikipedia

For pipe sizes less than NPS 14 inch (DN 350), both methods give a nominal value for the OD that is rounded off and is not the same as the actual OD. For example, NPS 2 inch and DN 50 are the same pipe, but the actual OD is 2.375 inches or 60.33 millimetres. The only way to obtain the actual OD is to look it up in a reference table.
