Jinding stainless steel welded pipe manufacturer is a professional manufacturer of stainless steel welded pipe manufacturers.

Because the surface density is relatively large, even if the surface is not polished, the outer surface can generally reach about 260 mesh. If the stainless steel welded pipe is polished inside and outside, the straightness of the pipe will decline, so the straightness of the steel pipe has special requirements. Generally, it is not recommended for polishing treatment. The surface of the stainless steel welded pipe after polishing has been very bright. Cold rolled stainless steel welded pipe has excellent comprehensive performance, can withstand high pressure, cold bending, expansion, flattening, no crack, no wrinkle, can do a variety of complex deformation and mechanical processing. After the stainless steel welded pipe is annealed by vacuum, the steel pipe can be processed. Stainless steel welded pipe is generally used in manufacturing machinery, hydraulic equipment, machinery and other production areas.

The popularization and application of stainless steel welded pipe can save steel, improve processing efficiency, reduce processing procedure and equipment investment, improve product quality and reduce cost. Because the size of the stainless steel welded pipe can be customized according to the needs of the user, and the tolerance range is well controlled, it can be used directly on the mechanical equipment without further processing. It can save the cost and greatly save the machining time, and improve the production and material utilization. Therefore, the accuracy of stainless steel welded pipe products will normally be controlled around 0.02 millimeters.

The polishing process inside and outside the stainless steel welded pipe is very important. Generally speaking, the steel tube with a diameter of less than 89 millimeters is highly polished after polishing. And more than 89 millimeter, especially 108 millimeter stainless steel welded pipe, the outer surface is not very ideal, if the welding pipe surface requires no small holes without pock, the general need to polish after polishing, and then automatic polishing.

Stainless steel welded pipe is a steel pipe with strict internal and external diameter precision (tolerance range), smooth finish, roundness, straight degree and uniform thickness of the inner and outer surface. The main technical indexes of stainless steel welded pipe produced by this technology have reached or partly exceeded the requirements of national standard GB12771--2002 and international standard ISO4394/I-1980 (E). Stainless steel welded pipe is a new type of high technology and energy saving product. The popularization and application of welded pipe can save steel products, improve machining efficiency and save energy.
