The Cheyenne Plains Gas Pipeline project is the first major pipeline in the U.S. to be constructed with X-80 grade pipe, and it used flux cored wire welding. The 36-in. pipeline runs a 380-mile span from the Cheyenne hub just south of Cheyenne, Wyo., to Greensburg, Kans., and transports 560 million ft3 of natural gas per day. Construction began in July 2004, and it was declared in service on January 31, 2005. Lincoln's Pipeliner® G80M gas shielded flux cored wire was selected by the evaluation team at U.S. Pipeline, Inc., as the consumable for semiautomatic fill and cap pass welding. Welding with the flux cored wire was used by U.S. Pipeline-contracted pipeline welders to join the extended pipe sections previously prepared by automated mainline welding operations. Semiautomatic welding was also used for pipe tie-in operations at connection points and road crossings.
