ASTM A53, API 5L, EN 10219 ERW steel pipe, also known as Electric Resistance Welding pipe (abbreviated as ERW), is used for transporting oil, gas, and other liquid or gaseous substances, meeting various high- and low-pressure requirements. Since hot-rolled coil is used as the raw material, the wall thickness of ERW steel pipe can be uniformly controlled within ±0.2mm.
