The inner wall of storage tanks is required to be galvanized; how can this be achieved?
Thread Content
There is currently an atmospheric pressure storage tank filled with propylene, and the client requires the inner wall of the tank to be galvanized. I have little experience in design and on-site work, and I’m not sure how to carry out galvanizing the inner walls of equipment; I was also unable to find clear information on this by searching online. Is it manufactured by directly purchasing galvanized steel sheets? Should the manufacturer purchase the steel plates and then galvanize them before welding? But how to ensure the weld? I found online that galvanizing steel sheets and galvanizing equipment are two different things. Or should the inner wall be galvanized after the equipment is manufactured? How is this achieved then? I hope fellow sailors will not hesitate to share their insights. Thank you all. :handshake
Is it possible to use thermal spraying? Zinc plating on one side of steel sheets is not easy to implement
Just saw the relevant standards for thermal spraying; it’s feasible to implement them with small-scale equipment； But for large storage tanks, might it be difficult to implement, especially regarding the tank top? :handshake
Is it about galvanizing the steel plate? So how should the weld area be handled? Thank you:handshake
For storage tanks of what size diameter are there alternative anti-corrosion solutions? For example, in terms of coating corrosion protection, if galvanizing is necessary, then reverse construction must be employed
With current technology, there should be no problem; find a professional construction company.
Thermal spraying: It is easier to carry out professional work on large equipment than on small ones. :D is rarely used these days, as it’s complicated to install, doesn’t save much money, and requires additional maintenance later on.
If a zinc bath large enough is available, overall hot-dip galvanizing of the equipment can be considered. We have previously manufactured mud-gas separators with similar requirements.
I’ve only heard of thermal spraying; I’ve never heard of on-site galvanizing.
