Welded carbon steel pipe is a pipe made by forming and welding coils or straight seam steel strips, which is both economical and applicable. It has high production efficiency and low cost, and is suitable for non-extreme working conditions such as low-pressure fluid transportation (such as water and gas), building structures, and general mechanical engineering. According to the welding process, it can be divided into straight seam welded pipe (ERW/LSAW) and spiral welded pipe (SSAW) to meet different specifications.

Electric Welded (ERW) Round Steel Tube is made of hot rolled coils through forming, high frequency resistance welding and other processes. Its weld is formed by melting the steel strip base material, and its mechanical strength is better than that of ordinary welded pipes. It has high production efficiency, low cost, high dimensional accuracy and uniform wall thickness. It is widely used in the fields of oil and natural gas transportation, building structures, and liquid transportation such as tap water and agricultural irrigation. It is an economical and practical pipe choice.
