JIS G3445 carbon steel mechanical pipe is suitable for machinery, automobiles, bicycles, furniture, appliances and other mechanical parts.

A335 Grade P2 Pipe is a low alloy carbon steel (Cr-Mo) that is self quench in air, where the welding adquire high hardnees and residual stress not recomended to put it directly in services that demand critical conditions.

ASTM A671 GR.CC60 steel pipe is a kind of pipe used for high-pressure purposes. It is mainly manufactured by electrofusion welding process and belongs to a grade in the ASTM A671 standard.

Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to form a bond. The longitudinal ERW seam does not require filler metal.
