Stainless steel welded pipes have gradually replaced seamless pipes and become the new favorite of industrial heat exchangers. In industry, stainless steel welded pipes are widely used, such as heat exchange pipes in heat exchangers, which require stainless steel welded pipes to achieve heat exchange function. Of course, some heat exchange tubes on the market still use stainless steel seamless tubes. But most of them use stainless steel welded pipes. Why?
1. Improvement of welding technology
Stainless steel welded pipes have been widely used in heat exchange, and their technology, quality and scale have also been greatly improved. As far as welding technology is concerned, the welding technology used has always been argon arc welding, plasma welding, combined welding and other welding methods to ensure the quality of stainless steel welded pipes. The improvement of stainless steel welded pipe welding technology also means that it can completely replace stainless steel seamless pipe for heat exchangers, boilers and superheaters.
2. Low cost and high efficiency
The production process of stainless steel seamless pipe is to heat the stainless steel strip (round tube blank) at high temperature in a furnace, and then punch holes with a punching machine. The whole process is expensive. The production cost of stainless steel welded pipe is relatively low, and the manufacturing efficiency is high. The welding process is easier to control the precision than the seamless pipe, the surface is smoother, and the construction speed is faster. Under the premise of mass production, the cost of stainless steel welded pipe is 20% lower than that of seamless pipe. And after welding, the quality of the joint is basically the same as that of wood. Therefore, stainless steel welded pipes can completely replace seamless pipes in industrial production.
At present, the domestic demand for stainless steel welded pipes is increasing year by year. Choosing stainless steel welded pipes can not only save costs, but also ensure quality.
