1. Friction heat is easy to be generated in cold drawing deep processing, so please use pressure resistant heat-resistant stainless steel pipe after the forming process is completed, remove the oil attached to the surface.
2. Before welding, rust, oil, water, paint, etc. harmful to welding shall be cleaned, welding rod suitable for steel type shall be selected. The time interval of spot welding is shorter than that of carbon steel. Stainless steel pipe brush shall be used to remove welding slag. After welding, the surface shall be polished cleaned to prevent local corrosion strength reduction.
3. Cutting stamping. Due to the higher strength of stainless steel tubes than ordinary materials, higher pressure is required in the stamping shearing process. As long as the gap between the cutter the cutter is accurate, it will cause poor shear work hardening. Plasma laser cutting. When the arc is cut off, the heat affected zone is ground needs heat treatment.
4. When the stainless steel pipe is processed bent, the thin plate can be bent to 180 degrees. However, in order to reduce the cracks on the curved surface with radius twice the thickness of the plate, the thick plate is given a thickness along the rolling direction which is twice the thickness of the plate is bent perpendicular to the rolling direction. A radius of 4 times the plate thickness should be provided, especially during welding. In order to prevent machining cracks, the surface of the welding area should be grounded.
5. Pay attention to prevent scratch adhesion of pollutants in the construction process, carry out stainless steel construction in the film-forming state. However, with the extension of time, the residual amount of paste solution depends on the service life of the membrane. After removing the film after construction, the surface should be cleaned stainless steel pipe tools should be used. clear.
6. Attention should be paid to make high corrosive magnetic luxurious stone cleaner contact the surface of stainless steel pipe. In case of contact, clean immediately. In order to prevent scratching contamination adhering during construction, stainless steel is constructed in the membrane state. However, with the extension of time, the residual amount of paste solution depends on the service life of the membrane. After the membrane is removed after construction, the surface shall be cleaned, stainless steel pipe tools shall be used for cleaning.
