Welded stainless steel pipe                   
Generally referred to as welded pipe, welded stainless steel pipe is a steel pipe made by crimping and welding stainless steel strips.                     
The strength of welded stainless steel pipe is lower than that of seamless stainless steel pipe,                      
but with the rapid development of production and the advancement of welding and inspection technology,                  
The improved quality of the weld seam makes it possible to replace seamless stainless steel pipes in many fields.                     
                       
Application:                   
Welded pipes are widely used in water supply engineering, petrochemical industry, chemical industry, electric power industry and so on.
