Determining Design Life Of Assemblies Of Polyethylene Pipe

Improvements in long-term performance of polyethylene (PE) piping compounds have created interest in the use of higher operating pressures for gas distribution piping systems. In Canada, this has culminated in the approval of PE 100 pipe with an operating pressure of 145 pounds per square inch gage (psig) for SDR 11 pipe, and the approval of PE 2708 PLUS and PE 4710 PLUS compounds that qualify for a 0.45 design factor for gas applications.
