Application scope of welded steel pipe

　　Welded steel pipe, also known as welded steel pipe, is a steel pipe made of steel plate or strip after rolling and welding. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are many, the equipment cost is less, but the general strength is lower than seamless steel pipe. Since the 1930s, with the rapid development of continuous rolling production of high-quality strip steel and the progress of welding and inspection technology, the quality of welding seam has been continuously improved, the varieties and specifications of welded steel pipe have been increasing, and the seamless steel pipe has been replaced in more and more fields. Welded steel pipe is divided into straight welded steel pipe and spiral welded steel pipe according to the form of weld.

　　Welded steel pipe products are widely used in boilers, automobiles, ships, construction of light structural steel doors and windows, furniture, all kinds of agricultural machinery, scaffolding, wire threading pipe, high-rise shelves, containers and so on. Can meet customer requirements, special specifications of welded pipe can be processed according to user requirements
