ASTM A53 ERW Steel Pipe

ASTM A53 Electric Resistance Welded (ERW) Steel Pipe is manufactured by rolling steel strip into a cylindrical shape and electrically welding the longitudinal seam. The weld is heat-treated after welding to eliminate untempered martensite, while weld flash is removed from both the internal and external surfaces to provide a smooth finish and improved performance. Manufactured in accordance with ASTM A53, ERW steel pipe is a high-quality carbon steel pipe with accurate dimensional tolerances and a lightweight construction. It is widely used for conveying oil, gas, steam, water and air under low to medium pressure, and is also suitable for general mechanical and structural applications.
