There is no essential difference in specifications and appearance between stainless steel industrial welded pipes and our existing 304 stainless steel decorative pipes. The main difference lies in the usage, as the requirements for industrial welding and surface of stainless steel pipes vary due to different uses;

Industrial welded pipes do not require polishing, acid pickling, sanding, or sandblasting because they do not care about the surface. The decorative tube requires a bright surface;

Industrial welded pipes have higher requirements for welding seams because they can be used as fluid pipes with internal pressure. They cannot be missed and must undergo water pressure and steam pressure testing processes, as well as eddy current testing processes;

304 stainless steel pipe

Industrial welded pipes have requirements for the smoothness of the inner wall and the flatness of the weld seam, as they can be used as a kit or fluid channel internally. The internal leveling or polishing process of the weld seam can be carried out according to customer requirements; And the decorative tube has no requirements for the inner wall;

Industrial welded pipes generally have a thicker wall thickness, ranging from 1.0 to 4.0, and some large pipes require 8-10 thicknesses; Decorative pipes generally have a relatively thin wall thickness, commonly ranging from 0.25 to 2.5;

Industrial welded pipes require higher corrosion resistance than decorative pipes, so they are mainly 304 stainless steel decorative pipes, as well as 3163213102205 and others; And 201 stainless steel pipes still hold a large proportion in the decorative pipe market;

With the continuous development of Chinese industrial products, stainless steel industrial welded pipes are partially replacing ordinary carbon steel welded pipes and partially replacing stainless steel seamless pipes, so the future usage will be increasing.
