A kind of anti-corrosion technology of stainless steel pipe

Abstract

The invention discloses a stainless steel pipe anti-corrosion process, which belongs to the technical field of stainless steel pipes. The invention can push the degreasing ring to migrate at high speed and force it to be synchronized by inserting a matching degreasing ring into the stainless steel pipe and relying on high-temperature steam flow. The degreasing liquid and gas are released. The degreasing liquid can fully contact the grease on the inner wall of the stainless steel, and can penetrate well under the assisted action of the gas. While improving the degreasing effect, it can fully squeeze out the deep grease of the stainless steel pipe, which is similar to the existing Compared with the state-of-the-art dipping method, the present invention converts the original passive infiltration into active infiltration, which not only greatly improves the degreasing efficiency, but also can effectively treat the deep layer of oil, thereby significantly improving the degreasing effect, ensuring the treatment quality of the subsequent process, and effectively Improve the anti-corrosion effect of stainless steel pipes.

Description

technical field [0001] The invention relates to the technical field of stainless steel pipes, and more specifically, relates to an anticorrosion process for stainless steel pipes. Background technique [0002] Stainless steel pipe is a kind of hollow long round steel. In all walks of life, stainless steel pipe has been widely used. The alloy of stainless steel pipe itself contains nickel, chromium and other components. Under normal conditions, stainless steel The stainless steel pipe will not rust, but it will oxidize in the marine climate or after encountering some chemicals. The specific performance is that yellow spots appear on the surface of the stainless steel pipe, which is commonly known as rust spots. The quality of the liquid circulating in the stainless steel pipe is affected. [0003] In the prior art, the following processes are mostly used for anti-corrosion treatment of stainless steel pipes: degreasing, grinding, sandblasting, pickling, passivation, coating ...

AI Technical Summary

Problems solved by technology

[0004] However, since the degreasing effect is carried out gradually from the surface of the oil stain, it needs to penetrate into the inside of the grease for wetting. For the deep grease on the stainless steel pipe, it is difficult for the degreasing liquid to penetrate in effectively, especially the inner wall of the stainless steel pipe, resulting in a poor degreasing effect. Poor, which affects the subsequent process effect
