Industry Overview

Galvanized steel pipe features a protective zinc coating that helps prevent corrosion

LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), also called SAWL pipe.

Electric resistance welding (ERW) is a welding process where metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. Electric resistance welding is widely used, for example, in manufacture of steel pipe.

Straight seam steel pipe is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. The production process of straight seam steel pipe is simple, with high production efficiency, low cost and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes.

Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight.

Cold-rolled seamless steel pipes are often of small diameter, and hot-rolled seamless steel pipes are often of large diameter.
