Corrosion protection of gas tanks
Thread Content
I took a look at the standards for wet-type gas cylinders: the inner surface of the cylinder, as well as the inner and outer surfaces of the bottom plate, all need to be painted (for corrosion protection). The foundation also requires special treatment. I have a few questions now: 1. Why does the interior of the gas cylinder need to be painted (for corrosion protection)? Is there corrosion inside? Is the water dirty? 2. Since the outer surface of the base plate does not come into contact with the medium, why is it still painted (for corrosion protection)? 3. Why does the foundation also need special treatment?
The corrosion protection for gas cabinets takes into account the fact that the medium consists of refinery exhaust gases containing sulfides such as hydrogen sulfide and benzene-like gases, which cause significant corrosion to the cabinet walls
