The stainless steel pipe is a kind of pipe with hollow cross section and complete weld. Compared with solid steel and other solid steel, stainless steel pipe products are a kind of economic section steel when the bending and torsion resistance is the same, it is a kind of economic section steel. It is used in the manufacture of structural parts and mechanical parts, such as oil drilling rod, automobile drive shaft, bicycle frame, and steel scaffold used in construction.
Using stainless steel pipe to make ring parts, it can improve the utilization of material, simplify the manufacturing process and save the length of material and processing, such as rolling bearing rings and Jack sleeves, all of which are made of stainless steel pipes. Because of its wide use and precision components, the finished products are basically smooth and no burr on the surface, so if you want to have better quality, the stainless steel electrolytic polishing process can be used to make the surface clean, no burr, and maintain a lasting light.
Manufacturing method of stainless steel pipe for fluid
In general, the temperature of the boiler pipes is below 450 C, and the domestic pipes are mainly made of 10 or 20 carbon steel hot-rolled pipes or cold drawn pipes. High pressure boiler pipes are often used at high temperature and high pressure, and their pipes will oxidize and corrode under the action of high temperature flue gas and steam. Therefore, it is necessary to make stainless steel pipe products have higher endurance strength, higher corrosion resistance and better stability.
The use of electrolytic polishing of stainless steel pipes is widely used. Generally, the boiler pipes are mainly used to make water wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large, small smoke pipes and arch pipes, and high pressure boiler pipes are mainly used to make superheater pipes and reheater pipes for high pressure and ultra-high pressure boilers. The trachea, main steam pipe and so on.
However, the stainless steel pipe also has some limitations, for example, under the condition of plane bending, the round pipe is not as strong as square and rectangular pipe, and some farm machinery skeleton, steel and wood furniture, etc. are commonly used and rectangular pipe. According to different uses, there are other special-shaped stainless steel pipes with different cross-section shapes. No matter what kind of stainless steel pipe, as long as the stainless steel electrolytic polishing treatment, its advantages are not successful, such as removing burr, can make the stainless steel surface to reach the 8K mirror effect, suitable for special shaped pipe fittings, such as high polishing efficiency, low production cost and long gloss. Corrosion resistance and antioxidation.
