Problems solved by technology

[0003] The existing high-temperature oxidation-resistant stainless steel pipes have certain disadvantages in the use process. First, the traditional stainless steel pipes are easy to collapse during the stacking process, which is not conducive to people's use. In addition, the traditional stainless steel pipes have relatively low high-temperature resistance and corrosion resistance. Low, which brings certain adverse effects to people's use process. Therefore, we propose a high-temperature oxidation-resistant stainless steel pipe and its preparation method

Abstract

The invention discloses a high-temperature-oxidation-resistant stainless steel pipe and a preparation method thereof. The high-temperature-oxidation-resistant stainless steel pipe comprises a pipe body, a pipe cavity is formed in the inner side of the pipe body, a second bonding layer is fixedly connected to the outer side of the pipe body, anti-rolling clamping ring bodies are fixedly connected to the two ends of the pipe body, an anti-corrosion layer is fixedly connected to the outer side of the second bonding layer, a first bonding layer is fixedly connected to the outer side of the anti-corrosion layer, a high-temperature-resistant layer is fixedly connected to the outer side of the first bonding layer, and four clamping grooves are formed in the periphery of the anti-rolling clamping ring bodies. According to the high-temperature-oxidation-resistant stainless steel pipe and the preparation method thereof, by adding the anti-rolling clamping ring assembly, stacking of the stainless steel pipe is facilitated, the adjacent pipe bodies are effectively fixed through the concave-convex mechanism of the clamping ring, by adding a comprehensive function layer, the high-temperature-resistant and anti-corrosion properties of the stainless steel pipe body can be greatly improved, and the application range of the stainless steel pipe is widened.

Description

Technical field [0001] The present invention relates to a stainless steel tube, and more particularly relates to a high-temperature oxidation and a preparation method Anti stainless steel tube. Background technique [0002] High temperature oxidation resistance of stainless steel tube is a stainless steel tube capable of resisting high temperature oxidation and has good oxidation resistance, corrosion resistance, continuous operation at high temperature, has good temperature resistance, with the development of science and technology, people increasingly high-temperature oxidation and a preparation method of a stainless steel tube manufacturing process requirements. [0003] Conventional high temperature oxidation resistance of stainless steel pipe has some disadvantages during use, first, a conventional stainless steel tube to collapse easily dispersed in the stacking process, it is not conducive to use, as well as conventional high temperature stainless steel corrosion resistant...
