? The most important process is bright annealing: stainless steel is heated to completely or basically dissolve carbide; The purpose of the heat treatment process of rapidly cooling to room temperature to obtain carbon supersaturated solid solution is to make the structure and composition of the material uniform, eliminate work hardening, and help to continue cold working and restore the inherent corrosion resistance of stainless steel.
? There is also straightening treatment: in order to ensure the straightness of stainless steel pipes, the welded stainless steel pipes need to be reshaped to length; It is also to improve the dimensional accuracy of stainless steel pipe and make the nozzle more rounded.
? It is necessary to pass weld flaw detection to prevent false welding and missing welding; There are also tests such as water pressure and air pressure, which must meet the customization requirements.
? Ba sanitary grade pipes are mainly used in gas pipeline systems with ultra-high purity requirements, such as biopharmaceuticals, high-purity gases, and electronic clean workshops.
