How is the degreasing treatment of stainless steel butt welding tee carried out?
Have you known the degreasing process of stainless steel butt welding tee? Licheng Steel will share its degreasing process with you below:
1. Before degreasing the stainless steel butt welding tee, it should be ground and tested to pass the pressure test, and then disassembled into parts, placed in a closed container for immersion in a solvent for 1-1.5 hours, and then taken out and hung in a ventilated place to dry. Metal washers, bolts and nuts, etc. can be degreased in the same way.
2. For non-metallic gaskets and fillers, soak them in the solvent for 15-20 minutes, then take them out and hang them in a ventilated place to dry them until there is no solvent smell. Pure asbestos fillers with strong oxidizing properties such as oxygen and concentration can be burned at a temperature below 300 ° C for 2-3 minutes, and then coated with the coating required by the design (such as graphite powder, etc.)
3. For copper gaskets, after annealing treatment, if there is no grease attached, no degreasing treatment is required. The stainless steel butt-welding tees and ceramic rings used in concentrated equipment can be washed or soaked with 93% concentrated solution, then rinsed with clean water, and then blown with steam until the steam condensate does not contain acid.
If under the condition of plane bending, the bending strength of the round pipe is not as high as that of the square pipe and the rectangular pipe, and the square pipe and the rectangular pipe are mostly used in some agricultural machinery skeletons, steel and wood clamps, etc. According to different purposes, special-shaped steel pipes with other cross-sectional shapes are also required:
1. Structural seamless steel pipe (GB/T8162-1999): It is a seamless steel pipe used for general structure and mechanical structure.
2. Seamless steel pipes for fluid transportation (GB/T8163-1999): general seamless steel pipes used to transport fluids such as water, gas, and oil.
3. Seamless steel pipes for low and medium pressure boilers (GB3087-1999): Used to make superheated steam pipes and boiling water pipes for low and medium pressure boilers of various structures, as well as superheated steam pipes, large smoke pipes, small smoke pipes and arches for locomotive boilers. High-quality carbon structural steel hot-rolled and cold-drawn seamless steel pipes for brick pipes.
4. Seamless steel tubes for high-pressure boilers (GB5310-1995): High-quality carbon steel, alloy steel and stainless heat-resistant seamless steel tubes for the heating surface of water tube boilers for high pressure and above.
The above is the introduction of the degreasing treatment of stainless steel butt welding tee.
