JFE Steel has developed an advanced electric resistance welding (ERW) linepipe "Mighty SeamTM." This new process controls the morphology and distribution of oxides generated during welding, and checks for flaws along an entire length of wolds on a real-time basis. "Mighty SeamTM" offers cost savings to extra low temperature services for which mainly seamless pipes or UOE pipes have been used until now.
