In recent years, the development trend of stainless steel welded pipes has been relatively good. Regardless of the scale, quality, and production technology, there have been relatively large advances, and in particular its demand areas have also gradually expanded. In addition, as the stainless steel welded pipe process becomes more and more mature, it can gradually replace the stainless steel seamless pipe in many applications, such as: heat exchanger equipment, medium and low pressure boiler tubes and so on.

Stainless Steel Welded Pipe Production Features:

light production equipment, low investment, construction speed, welding method is simple, a wide range of product specifications, high dimensional accuracy, small wall thickness deviation, smooth surface, high rate of finished products. In the case of mass production, the cost of the welded pipe is 20% lower than that of the seamless pipe. In recent years, the “welding-cold rolling” process of producing stainless steel tubes used in the country has been cold-rolled (pulled out) after cold-rolled coils have been slit and shaped according to specifications, and then welded into tubes by multiple gun argon arc welders. The performance indicators of the weld can be basically the same as the parent metal, and the product quality is obviously improved. Therefore, the advantages of using stainless steel welded tubes instead of stainless steel seamless tubes have become increasingly apparent.
