Stainless Steel Weld Tee Before degreasing, the parts should be ground and tested for qualified pressure, then disassembled into parts, soaked in the solvent of a closed container for 1 to 1.5 hours (the pressure should be adjusted again after the safety valve is degreased), and then taken out and hung in a ventilated place to dry; other metal stainless steel pipe fittings, metal gaskets, bolts, nuts, etc. can be degreased in the same way.

Non-metallic gaskets and elbows can be soaked in solvent for 15 to 20 minutes, then hung in a ventilated place to dry until there is no solvent odor. Pure asbestos fillers that are exposed to strong oxidizing media such as oxygen and concentrated can be burned at a temperature below 300°C for 2 to 3 minutes, and then coated with the coating required by the design (such as graphite powder, etc.).

After annealing, if the pipe fittings, elbows, etc. are not contaminated by grease, degreasing is no longer required. Stainless steel butt welding tees, porcelain rings, etc. used in concentrated equipment can be washed or soaked with 93% concentrated, then rinsed with clean water, and then blown with steam until the steam condensate does not contain acid. Such as under the condition of plane bending.
