How to remove rust from new pipes!
Thread Content
Please tell me how to remove rust from a pipe completely covered with oxide scale? To what extent is rust removed? How to do manual rust removal?
Industrial cleaning agents can remove rust, such as rust removers. Rinse with water afterwards. This is what our company does.
We use a professional team to pneumatically sand and repaint.
When processing in large quantities, it can be pickled, phosphated, and then sprayed with anti-rust paint. --
Sandblasting and rust removal or grinding with a manual grinder, standard sa2.5 or ST3.0 level is enough, and then anti-corrosion
There is now a rust converting agent that is particularly effective for minor rust. It is directly applied to the surface to cause the rust layer to react without continuing to rust. The specific principle is not very clear. I have only seen Solei Industrial use this product when it was used to treat leaks in gas pipelines.
Centralized anti-corrosion by shot blasting or sand blasting is commonly used in engineering projects. If there are no conditions, you can also choose mechanical rust removal. Your pipe is so new that it is difficult to remove the oxide layer through mechanical rust removal. The diameter of the spiral submerged arc welded steel pipe is also relatively large. It is recommended that shot blasting be used for high efficiency. Underground pipes can be made of 3PE, heat shrink tape, or glass fiber cloth at low cost. Just make the above ground pipes out of epoxy material.
