Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe equipment, in particular to a high-pressure resistant stainless steel pipe. Background Art

[0002] Stainless steel pipe is a hollow, long, round steel bar, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. In addition, it is lighter in weight when the bending and torsional strength are the same, so it is also widely used in the manufacture of mechanical parts and engineering structures.

[0003] The application number is CN202322583788.0, which discloses a high-pressure resistant stainless steel pipe, including pipe one, wherein one end of the pipe one is clamped with the pipe two, the end of the pipe one close to the pipe two is fixedly connected with a plug, the end of the pipe two close to the pipe one is fixedly connected with a connecting end, the plug is inserted into the connecting end, and the end of one side wall of the pipe close to the pipe two is fixedly connected with a connecting block two, and the end of the side wall of the pipe two close to the pipe one is fixedly connected with the connecting block one; by inserting the plug at one end of the pipe one into the connecting end at one end of the pipe two, and then fitting the connecting block two on the pipe one and the connecting block one on the pipe two to each other, fixing the connecting block one and the connecting block two by bolts, so that the pipe one and the pipe two are fixed and will not be detached. The high-pressure resistant stainless steel pipe does not require welding when connected, and is easy to install and disassemble. The disassembled stainless steel pipe will not be damaged and can be reused, thereby improving the utilization rate of the stainless steel pipe.

[0004] The above document discloses a high-pressure resistant stainless steel pipe with the following defects: when the stainless steel pipe needs to be closed on one side during use, a cover is usually installed at one end of the pipe. When the water flows forward to hit the pipe cover, when the water flow is relatively intense, the cover can be easily blown open by the impact force, reducing the stability of the stainless steel pipe.

[0005] It can be seen from this that the existing stainless steel pipe does not have the function of strengthening the sealing connection with the pipe cover. It is necessary to improve the existing deficiencies and provide a function that can strengthen the sealing connection with the pipe cover. Summary of the Invention
