Black carbon round steel pipe, 2.5 inch schedule 40 black iron pipe, st37 pipe

ERW welding round pipesalso are called as Electric Resistance Welded Pipes.This type of steel pipes and tubes are widely used in various fields such as engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.

While manufacturing ERW steel pipes, there are some strictly standard: high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel. High performance ERW steel pipes and tubing possess high strength corrosion resistance, high deformability, high strength and high toughness.

 • ERW welding steel pipe is available with square ends or beveled for welding, threaded and coupled and victaulic grooved.

 • Surface finish are available in black or bare, or with protective coatings.
