Developement of stainless welded tube
In recent years, the development trend of stainless steel welded pipe has been better. No matter in scale, quality, production technology has made great progress, especially its demand field has gradually expanded. In addition, with the stainless steel welding tube process more and more mature, in many applications can gradually replace stainless steel seamless tube, such as: heat exchanger equipment, low pressure boiler tube, etc.
Stainless Steel Welded Pipe Production Features
Light production equipment, low investment, fast construction speed, simple welding method, wide range of product specifications, high dimensional accuracy, small wall thickness deviation, smooth surface, high yield. In the case of mass production, welded tubes cost 20% less than seamless tubes. In recent years, the weld-cold rolling process of domestic stainless steel pipe is to open the cold rolling coil according to specifications, and then cold rolling (pull out) after shaping, and then welded into the pipe by multi-gun argon arc welding machine. The performance of the weld is basically the same as that of the base metal, and the product quality is obviously improved. Therefore, the advantages of using stainless steel welded pipe instead of stainless steel seamless pipe are more and more obvious.
