[0021] The stainless steel pipe with anti-leakage connection in the utility model is similar to the existing stainless steel pipe structure, such as the patent with announcement number CN219120010U discloses a precision cold-rolled stainless steel pipe. The main improvement of the utility model is: through the fixing mechanism 3 to the sealing gasket 2, the sealing gasket 2 is wrapped around the connection of the stainless steel pipe, so as to achieve the purpose of preventing leakage at the connection of the stainless steel pipe, and through the reminder component 4 to understand whether the connection of the stainless steel pipe leaks, so as to deal with it. Figures 1 to 6 As shown, when using the stainless steel pipe for preventing leakage at the connection in the utility model, first insert the slider 404 into the slide groove 402, wrap the first arc rubber block 201 on the surface of the steel pipe body 1, and align the annular groove 401 with the connection of the stainless steel pipe, adjust the third arc rubber block 203 to stick to the surface of the second arc rubber block 202, and then place the first semicircular plate 301 of the fixing mechanism 3 on the surface of the sealing gasket 2, rotate the second semicircular plate 306 until the second arc groove 403 on the rotating second semicircular plate 306 is placed directly above the slider 404, and the arc plate 309 at the front end of the second semicircular plate 306 is inserted into the first arc groove 309 of the inner wall of the front end of the first semicircular plate 301. 08, and fix the first semicircular plate 301 and the second semicircular plate 306 on the first fixing plate 302 and the second fixing plate 307 with bolts and screws, so as to ensure the fixation of the sealing gasket 2, so as to prevent the stainless steel pipe connection from leakage. When the stainless steel pipe connection leaks, the annular groove 401 is filled with liquid or gas, and the air in the annular groove 401 is compressed. Under the action of air pressure, the slider 404 moves upward along the slide groove 402 and the second arc groove 403, and the front end of the slider 404 exceeds the upper surface of the second semicircular plate 306, so as to facilitate observation, so as to remind the staff that the stainless steel pipe connection leaks and deal with it.

[0024] like Figure 2 As shown, the sealing gaskets 2 are all fluorosilicone rubber blocks.

[0025] Specifically, the performance of the fluorosilicone rubber block combines the advantages of fluororubber and silicone rubber, and has excellent oil resistance, solvent resistance, fuel oil resistance, and high and low temperature resistance. It also has good elasticity and can adapt to various harsh environments, ensuring that the sealing gasket 2 can play a role in sealing and leak prevention in various harsh environments.
