(AdvancedSteelBook)DEVELOPMENT OF HIGH STRENGTH LINE PIPE FOR ARCTIC APPLICATIONS

摘要

The design of pipelines to transmit natural gas from the Mackenzie Delta and the Alaska NorthSlope to Alberta will place stringent new requirements on material performance. The necessity oftransmitting large volumes of gas over long distances provides the impetus to increase operating pressures.In turn, the higher pressures require higher strength steels and/or greater wall thickness. As well, Arcticconstruction in which the pipeline must traverse areas of continuous or discontinuous permafrostnecessitates the use of low operating temperatures and strain-based designs. This presentation willhighlight initial development of X80 and X100 line pipe for Arctic applications.
