Stainless Steel welded pipe

Product description

Stainless steel welded pipe, referred to as welded pipe, is a steel pipe made by welding steel or steel strip after curling and forming by a unit and a die. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are many, and the equipment investment is small, but the general strength is lower than that of Seamless steel pipe. Since the 1930s, with the rapid development of high-quality strip steel continuous rolling production and the advancement of welding and inspection technology, the quality of welds has been continuously improved, and the varieties and specifications of welded steel pipes have increased day by day, and have replaced seamless steel pipes in more and more fields, especially in heat exchange equipment pipes, decorative pipes, medium and low pressure fluid pipes, etc.
