Welded pipes are also called welded steel pipes, which are basically made of steel plates or strips that have been welded after being crimped. The production process of welded steel pipe is simple, the production efficiency is high, there are many varieties and specifications, and the equipment cost is small, but the general strength is lower than that of seamless steel pipe. With the rapid development of high-quality strip continuous rolling production and the improvement of welding and inspection technology, the quality of welds has been continuously improved, and the variety and specifications of welded steel pipes have been increasing. Welded steel pipe is divided into straight seam welded pipe and spiral welded pipe according to the form of weld.

classification

Welded pipes are classified according to purpose: they are divided into general welded pipes, galvanized welded pipes, oxygen blown welded pipes, wire sleeves, metric welded pipes, idler pipes, deep well pump pipes, automotive pipes, transformer pipes, electric welding thin-walled pipes, electric welding Shaped pipe and spiral welded pipe.
