Canadian Standard Revised To Incorporate Higher Performance Plastic Pipe

December 2010 Vol. 237 No. 12

Revisions have been approved to the Canadian standard dealing with the use of plastic pipe in oil and gas pipeline systems. The standard is CSA Z662-11 “Oil and Gas Pipeline Systems.” The revisions to be published next year include:

  • Added rapid crack propagation (RCP) required value of a full-scale critical pressure greater than 1.5 times the maximum operating pressure for polyethylene (PE) materials…

Advanced Research Under Way On PE Pipe For Natural Gas

October 2010 Vol. 237 No. 10

Modern polyethylene (PE) pipe’s capabilities and characteristics have improved greatly since first installations more than 40 years ago. Interest in PE pipe has expanded widely throughout the gas distribution industry. NYSEARCH/Northeast Gas Association is conducting research that is revealing the strengths and durability of modern PE pipe with notable results. Incorporating these revelations into industry standards could result in benefits on many levels.

Rapid Crack Propagation Increasingly Important In Gas Applications: A Status Report

December 2008 Vol. 235 No. 12

Polyethylene (PE) is the primary material used for gas pipe applications. Because of its flexibility, ease of joining and long-term durability, along with lower installed cost and lack of corrosion, gas companies want to install PE pipe instead of steel pipe in larger diameters and higher pressures. As a result, rapid crack propagation (RCP) is becoming a more important property of PE materials.
