How To Remove Rust from High Pressure Boiler Tubes

There are many reasons for rusting of high-pressure boiler tube, among which the main reasons include oxidation corrosion, sulfate corrosion, chloride corrosion and sulfide corrosion. So, how to remove rust is often what we need to think about. This article will provide the following four methods for reference:

 

Cleaning

Use solvents and emulsions to remove oil, grease, dust, lubricants and other similar organic matter, but cannot remove rust, scale, solder, etc. on the surface of high-pressure boiler tubes. It can only be used as an auxiliary means of anti-corrosion production.

 

Special tool anti-rust treatment

Key application of special tools such as steel brushes can remove dirt, rust, splashes, etc. on the surface of high-pressure boiler seamless pipe that are damaged, loose, and swelled. The anti-rust treatment of manual tools can reach Sa2 level, and the anti-rust treatment of power tools can reach Sa3 level. If the surface of high-pressure boiler seamless steel pipe is adhered to solid dirt, the anti-rust treatment effect of the tool is not ideal, and the steel anchor depth required by FRP anti-corrosion cannot be achieved.

 

Pickling

Generally, chemical and electrolytic methods are used for pickling. Pipe corrosion can only be treated by chemical pickling, which can remove scale, rust, and old coating. Sometimes it can be used for sandblasting after rust treatment. Although chemical water treatment can make the surface clean and smooth to a certain extent, its anchor line is shallow and easy to pollute.

 

Sprayer anti-rust treatment

Sprayer anti-rust treatment is a high-power electrospray blade running at high speed, so that diamond sand, bearing steel balls, stainless steel wire, minerals and other wear-resistant materials are sprayed (points) on the surface of seamless steel pipe under the action of centrifugal force, which can not only completely remove rust, metal oxides and stains, but also can be damaged and rubbed in high-pressure boiler seamless steel pipes to achieve the required uniform surface roughness.

 

In summary, spray anti-rust treatment is an ideal rust removal method for pipeline corrosion protection. Generally speaking, spray anti-rust treatment is mainly used for the surface treatment of high-pressure boiler steel pipes, and shot peening is mainly used for the surface treatment of pipelines.
