Product Description
Stainless steel welded pipe.
Stainless steel welded pipe commonly used steel or steel strip through the unit and mold coil molding after welding made of steel
pipe. Welded steel pipe production process is simple, high production efficiency, more varieties and specifications, less
equipment investment, but the general strength is lower than seamless steel pipe.
With the rapid development of high-quality strip steel continuous rolling production and the progress of welding and inspection
technology, the quality of weld seam is constantly improved, the varieties and specifications of welding steel pipe are
increasing, and in more and more fields, especially in the heat exchange equipment with pipe, decorative pipe, medium and low
pressure fluid pipe instead of seamless steel pipe.
