ERW steel pipe is rolled by Cold-formed steel strip or coil and then resistance welding along the seam where the edges meet, without the need for additional welding material. Due to lack of weld metal, the pipe is with Smooth internal surface which can improve flow rates for liquid transportation. ERW steel pipe can be produced as per ASTM/ASME or EN standard. Different standard have the difference out diameter and thickness
