Polyethylene (PE) pipes and fittings are used extensively in distributing natural gas and water safely, reliably and economically, and enjoy an excellent performance track record. PE offers the pipe industry:
Pipeline leakage, breakage and other critical issues can create multiple environmental problems, cost utilities millions in lost revenue and delay important services to customers. There is no doubt that reliability is key – and that includes starting with the right pipeline distribution system manufactured with the right ingredients.
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…
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.
Ever since Union Gas in Caney, KS successfully inserted a 4-inch polyethylene pipeline into a corroded 6-inch steel pipeline in 1959, polyethylene pipes have steadily become the material of choice for the North American gas distribution market.
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.
