Jul 31, 2020 · The biggest difference between straight seam high frequency electric resistance welded pipe (referred to as ERW) and seamless steel pipe is that ERW has a weld, which is also the key to the quality of ERW steel pipe. Modern ERW steel pipe production technology and equipment, due to years of unremitting efforts internationally, especially in the United States, has made the seamlessness of ERW steel pipes China Straight Seam Steel Pipe, Straight Seam Steel Pipe ASTM A53 Carbon ERW Welded Steel Pipe, API 5L 0.5-8 Inch Sch40 Straight Seam Steel Pipe and Tube for Oil and Gas FOB Price:US $ 1100-2200 / Ton Min. Order:1 Ton
Difference in ERW and SAWL. Straight seam welded steel pipe, according to welding process can be divided into high frequency resistance welding and submerged arc welding, longitudinal submerged arc welded is short for SAWL, high-frequency straight seam resistance welding is short for ERW. ERW Tube Mill Steel Pipe Manufacturing Machine - HNGK ERWERW Tube Mill Steel Pipe Manufacturing Machine. Straight seam welded pipe mill also is called ERW mill. The plate in certain width after slitting line and stripping is unfolded and leveled. Then, they are sent into forming machine. Used the roller, the plate is bent into pipe state. The edge of the steel plate is melted by making use of the GEIT Pipe Welding Equipment FactoryGEI-219 straight seam welded steel pipe mill machine. GEI-32 ERW tube mill machine. High frequency welding ERW pipe welding machine. ERW tube mill line. ERW steel pipe/tube making machine for round, square and rectangle pipes/tubes. GEI-630 ERW steel tube mill. GEI-89 steel tube mill. SSAW pipe
