Problems solved by technology

[0003] Existing stainless steel pipes generally adopt threaded connection, but the threaded connection has the problem of unsatisfactory sealing effect. Leakage is prone to occur at the connection part of the stainless steel pipe, and when leakage occurs, the liquid in the stainless steel pipe will overflow to the threaded connection part. Causes the threaded connection to be in a wet state for a long time, which leads to corrosion of the threaded connection

Abstract

The invention discloses a high-strength anti-corrosion semiconductor electropolishing stainless steel pipe, and relates to the technical field of stainless steel pipes. The high-strength anti-corrosion semiconductor electropolishing stainless steel pipe comprises a pipe body, one end of the pipe body is provided with an external thread, the other end of the pipe body is coaxially sleeved with a butt joint, the inner diameter of the butt joint is equal to the outer diameter of the pipe body, and the butt joint is internally provided with an internal thread matched with the external thread. Whentwo adjacent pipe bodies are butted together, the end, provided with the external thread, of any pipe body is in butt connection with the end, located in the butt joint, of the other pipe body. A plurality of sections of non-parallel butted surfaces are formed between the butted pipe bodies, so that the sealing performance of the butted pipe bodies is effectively improved.

Description

technical field [0001] The invention relates to the technical field of stainless steel pipes, in particular to a high-strength anti-corrosion semiconductor electropolished stainless steel pipe and a preparation method. Background technique [0002] Stainless steel is an economical section steel that saves metal and is an important part of high-efficiency steel, especially in oil drilling, smelting and transportation industries. Manufacturing as well as industries such as boilers and medical devices also require large quantities of stainless steel pipes. [0003] Existing stainless steel pipes generally use threaded connections, but the threaded connection has the problem of unsatisfactory sealing effect. Leakage is easy to occur in the connection part of the stainless steel pipe, and the liquid in the stainless steel pipe will overflow to the threaded connection part when leakage occurs. As a result, the threaded connection is kept in a wet state for a long time, which in t...
