TP304 welded stainless steel pipe
Stainless steel welded pipe is usually made of stainless steel plate or steel strip after crimping and forming by the machine set and die.
304 stainless steel welded pipe has the advantages of simple production process, high production efficiency, more varieties and specifications, and less equipment funds, but its compressive strength is generally lower than that of stainless steel seamless pipe.
In recent years, with the rapid development of high-quality stainless steel strip continuous rolling production and the progress of stainless steel welding and inspection technology, the quality of welding seam is constantly improved, and the varieties and specifications of welded stainless steel pipe are increasing day by day, and stainless steel seamless steel pipe is replaced in more and more fields, especially in heat exchange standby pipe, decorative pipe, medium and low pressure fluid pipe, etc.
