Characteristics of Weld Seam of ERW Steel Pipe

The biggest difference between straight seam high frequency electric resistance welded pipe (ERW Pipe) and seamless steel tube is that ERW has a weld, which is also the key to the quality of ERW steel pipe.Difference in ERW and SAWL - Guangdong Lizz Steel Pipe High frequency resistance welding steel pipe( ERW steel pipe) because of its welding and submerged arc welding in the welding process, ERW process does not add any welding materials, welding without heat melting state of weld metal, just after the recrystallization process, the formation of the weld and base material chemical composition straight seam welded steel pipe welding steel pipe and tubeDifferenciating between straight seam and electric straight seam welded steel pipe welding steel pipe and tubeJan 28, 2019Straight seam steel pipe is a steel pipe whose weld is parallel to the longitudinal direction of the steel pipe. Usually divided into metric electric welded steel pipe, welded thin-walled pipe, transformer cooling oil pipe and so on.
