Characterization of Tensile and Fracture Properties of X52 Steel Pipes and Their Girth Welds
DownloadSpring 2015
Enbridge vintage Norman Wells Pipeline made of X52 steels has transported crude oil from Norman Wells, Northwest Territories (NWT) to Zama, Alberta since 1985. It is the first fully buried pipeline that traverses permafrost regions in Canada, and is often subjected to adverse geotechnical...

Novel XFEM Variable Strain Damage Model for Predicting Fracture in Small-scale SENT and Full-scale Pipeline Fracture Tests
DownloadFall 2021
Of all the common integrity threats of steel pipelines, cracking is the most dangerous and potentially resulting in the immediate loss of pressure containment capacity. Industry pipeline operators should ensure that the tensile train capacity (TSC) of welded pipeline exceeds the longitudinal...
