Cross-Weld Creep-Rupture Testing for Seam Weld Life longitudinal seam welding pipe

Longitudinal seam-welded hot-reheat steam piping operating in the creep regime is a continuing life-management challenge for many older fossil-fired power plants. In response to catastrophic seam-welded piping failures in the 1980s, the Electric Power Research Institute (EPRI) developed a comprehensive inspection protocol to insure continued safe operation of these piping systems [1]. The longitudinal seam welding pipeDifference between helical welded pipes and longitudinal longitudinal seam welding pipeAs the name shows, longitudinal pipe has a straight welding seam on the pipe surface. Different from the longitudinal pipe, the welding seam of which is vertical to the axial line of the pipe, helical welded pipe is rolled and welded according to certain helical angles.
