Help! Anti-corrosion treatment of gas supply pipeline
Thread Content
The image shows copper gas supply pipes. Given the presence of ammonia in the working environment, which can corrode copper pipes, is it possible to apply a layer of material over the outer surface of the exposed copper pipes to prevent contact with ammonia? If so, what should be used for this purpose? I’m in a bit of a hurry; I hope the experts here can offer some guidance. Thank you!
Ban copper for ammonia! There’s nothing to say; change it to stainless steel.
It’s already installed; it’s too troublesome to make changes – the amount of work involved is quite large. Is there any effective way to do it without making any changes?
Is it okay to apply anti-corrosion paint? Anyway, since there is concern about ammonia in the atmosphere, wouldn’t it be sufficient to provide some shielding? One of the important functions of painting is to shield the pipeline from contact with the atmosphere. Use epoxy phenolic primer + epoxy ferrochrome intermediate coat + polyurethane topcoat for shielding? I wonder though what the brushing effect will be on such thin tubes?
Wrap with PTFE tape, evenly, temporarily
A valve for a copper pipe is only about 1 meter long – why is the workload so large? In the future, it is best to use stainless steel pipes for any project, and they should be polished.
What kind of environment is that, with such a high level of ammonia? Won’t the environmental authorities investigate you?
