What is the difference between stainless steel seamless steel pipe and precision stainless steel pipe?

Stainless steel pipes include welded pipes and seamless pipes, but most people think of seamless pipes when talking about stainless steel pipes. They think stainless steel pipes are seamless. In fact, stainless steel pipes also have welded pipes. Next, we will talk about the difference between stainless steel seamless steel pipes and stainless steel pipes.

Seamless tube is made of round tube ingot by cold rolling, cold drawing or hot extrusion production process. Because the seamless steel pipe is processed with round steel ingot, the precision of the steel pipe is low, the wall thickness is not uniform, the internal and external surface brightness is low, the sizing cost is high, and after multiple heating, the internal and external surface of the steel pipe is easy to produce black spots, which is not easy to remove.

In addition, the steel composition used for seamless pipe production only meets the basic requirements, and various unstable factors occur during the welding process, making it difficult to firmly weld and weld through. Seamless pipes also have metal delamination and residual stress. The price of seamless pipe is higher than that of welded pipe.

The stainless steel pipe is welded by the steel strip after the machine and the mold are crimped. In addition, the welded pipe avoids multiple heating treatments during the processing process, making the production process more environmentally friendly and safe. Thanks to the use of processed stainless steel strips as raw materials, the tubes produced have high precision, uniform wall thickness, high surface brightness inside and outside the tubes, and can be adjusted arbitrarily according to customer needs.
