Anti-corrosion treatment method of branch pipe stand in steel plant

The various energy transmission pipelines laid by the steel plant are supported by pipeline supports (hereinafter referred to as "branch pipe stands") arranged on pillars. The branch pipe stand is composed of a lower steel support stand and an upper steel pipe clamp ring. In the state of supporting the pipeline, a gap will be formed between the branch pipe stand and the pipeline. Specifically, it is the gap between the pipe and the pipe branch, the gap between the pipe and the steel clamp ring, and corrosion sometimes occurs in these gaps.

After loosening the steel clamp ring, the rust caused by the crevice corrosion under the clamp ring was observed. It can be considered that the rust phenomenon caused by the crevice corrosion under the clamp ring is caused by the difficulty of drying after rainwater penetrates into the crevice. Sometimes it will eventually lead to perforation of the pipe, so it must be treated with anti-corrosion. The anti-corrosion treatment method is to unload the pipe from the branch pipe stand and paint the cracks, but this not only costs a lot of money, but also may cause gas leakage when the pipe is unloaded, so it can only be unloaded when the gas is stopped. Down the pipeline. Since the production of the steel plant is 24 hours a day and night, once the gas transmission is stopped, it will have a significant adverse effect on the steel plant's production plan. Therefore, it is hoped that there is a method of anti-corrosion treatment without unloading the pipeline.

Therefore, Chinese steel mills have developed anti-corrosion treatment methods for branch pipe stations. That is, a method of press-fitting a low-viscosity urethane resin paint that easily penetrates into the gap between the pipe and the branch pipe or the steel clamp ring. When pressing in the low-viscosity urethane resin paint, in addition to the paint injection part and the discharge part, the two ends of the branch pipe stand and the steel clamp ring should be sealed and fixed with a sealant in advance, so that the paint can penetrate the entire gap . The low-viscosity urethane resin coating will capture the moisture in the gap during the hardening process after penetration. Therefore, even if the moisture in the gap penetrates into the paint, it does not matter, and the anti-corrosion effect is still ensured.

This anti-corrosion treatment method can be applied to branch pipe stands of steel mills, and can also be used for anti-corrosion treatment of gaps between the bottom of rolling mills and base plates, and anti-corrosion treatment of narrow parts of steel bridges. The scope of application is expanding, such as the anti-corrosion of gaps in other equipment. deal with.
