Plastic Pipe – Where Past Is Prelude

December 2014, Vol. 241, No. 12

Although plastic pipe has been actively used in the natural gas industry since the late 1950s, it is still considered by some to be the “the new kid on the block.” Perhaps one of the key reasons for this reputation is the fact that the plastics industry continues to push the envelope in creating higher performance materials that inspire new compositions and installation techniques. And the main benefactors are gas utilities, exploration and production companies and ultimately their customers.

Determining Design Life Of Assemblies Of Polyethylene Pipe

December 2014, Vol. 241, No. 12

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.
