| Abstract: | Low and inconsistent impact energy of the weld seam is regarded as a major technological prob-lem relating to manufacturing of ERW linepipe. Addressing the problem of inconsistent impact energy of the hi-grade L450MB ERW pipe,the Steel Tube Plant,Baogang Co.,Baoshan Iron & Steel Co.,Ltd. has produced by trial the L450MB ERW linepipe which is up to the impact toughness of weld seam as specified in applicable stan-dard by adopting a technical solution involving such actions as reducing the welding speed and adjusting the heat treatment process. |
