Ammonia corrosion?
Thread Content
There is an ammonia compressor in this workshop. The anti-corrosion paint of the surrounding equipment such as the auxiliary tank has fallen off, and the anchor bolts are also severely corroded and rusted. Do you have any tips? Can you give me some advice?
Nowadays, there are many anti-corrosion techniques, and spraying plastic after polishing is also good!
There are many methods of exterior anti-corrosion, and they all have good results. The key is to control the construction quality! ! !
If it is indeed corroded by ammonia or ammonia gas, the fundamental solution I want to solve is to check whether there is any leakage in the ammonia compressor. As long as good air tightness is maintained and ammonia gas does not leak, the problem of ammonia corrosion can be fundamentally solved.
Ammonia corrosion: Find the source of the leak. Consider plastic spraying for anti-corrosion.
You can consider cathodic protection, ammonia corrosion is very serious.
If you are really rich, the procedures for scrapping state-owned equipment are enough to annoy you to death.
Rust removal is ST3 level, then apply two coats of polyurethane heavy anti-rust primer, one coat of intermediate paint, and finally two coats of topcoat. The service life is more than 20 years. The key is to improve the quality of rust removal construction (this seems to be more difficult in state-owned enterprises. I almost started a fight with the construction unit in order to improve the quality. The construction unit is not afraid of us at all!)
Does anyone know how corrosive ammonia is to carbon steel? If the medium is 20% ammonia, is it okay to use No. 20 steel?
