Anti-corrosion and rust removal of methanol storage tanks
Thread Content
May I ask all heroes?: How should I remove rust from a newly built 500 cubic methanol storage tank? And how to do embalming? Thank you all for your advice!
Do newly built tanks also need to be rust removed? 1. Drain as much methanol as possible from the tank ； 2. Use sealing mud to seal the flanges on the pipes connecting the tanks and other places where leaks may occur. ； 3. Contact a professional anti-corrosion operation team for the operation, and make technical briefings before operation.
The new tank siding is covered in rust
No way? This situation shouldn't happen. Generally, this situation is caused by the large temperature change of the methanol in the tank. Do you often send high-temperature methanol into this tank? Is this tank filled with crude methanol?
If it is a new tank, it should be separated from the other tank with a shield, strictly follow safe operations at high altitudes, choose good weather, and the wind direction is opposite to the other tank. Polish the rusty areas and blow with air, apply anti-rust paint and wait for it to dry before applying anti-rust paint again.
It is best to use sandblasting to remove rust internally, and it is best to be lined with fiberglass.
Are you talking about internal defense or external defense? There are standards for anti-corrosion in methanol irrigation areas, and our large and small tanks do not have internal anti-corrosion. Because some anti-corrosion coatings may affect the quality of methanol over time. Pure methanol is non-corrosive.
Before making the tank, the bottom and outer wall of the tank should be sandblasted, rust-removed and anti-corrosion. Contact a chemical cleaning company for chemical cleaning and passivation of the inner wall and bottom of the tank.
Drain liquid to lower the liquid level, isolate from surrounding tanks, isolate from external pipelines (add blind plates or remove them), remove surrounding flammable materials and ignition sources, conduct fire analysis, technical briefing, set up shelves, and handle work tickets
There is a manufacturer that specializes in anti-corrosion on the inner walls of methanol storage tanks. They apply a layer of paint on the inner walls of the storage tanks. It is anti-corrosion and can conduct static electricity. Do you think it is unnecessary?
