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 North Slope to Alberta will place stringent new requirements on material performance. The necessity of transmitting 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, Arctic construction in which the pipeline must traverse areas of continuous or discontinuous permafrost necessitates the use of low operating temperatures and strain-based designs. This presentation will highlight initial development of X80 and X100 line pipe for Arctic applications.
