X80 Pipe Calls for CC/CV Welders

摘要

Cheyenne Plains Gas Pipeline recently constructed a $425 million natural gas line from Cheyenne, Wyo., to Greensburg, Kan., using 385 miles of X80 steel pipe, a material never before used for pipelines in the United States. Welds on the high-yield steel are prone to hydrogen cracking. The most productive solution for tie-in welds called for a combination of stick and flux-cored wire welding, and that put Miller's PRO 300 CC/CV welding generators in the hands of many pipeline welders for the first time.
