Stainless Steel Welded Pipe

Stainless steel welded pipe commonly made from steel or steel strip after crimp units and dies made of welded steel pipe.Welded steel pipe production technology is simple, high production efficiency, varieties, specifications, less equipment investment, but the general strength is lower than the seamless steel tube.Since the 1930 s, with the rapid development of high quality strip steel rolling production and the progress of welding and inspection technology, constantly improve the weld quality, increasing varieties of welded steel pipe specifications, and in the field of more and more especially in heat exchange equipment with low pressure fluid in pipe, decorative, pipe instead of seamless steel tube.
