Corrosion prevention issues in stainless steel gas storage tanks
Thread Content
Our company has a stainless steel gas storage tank, and the client requires painting of its outer surface. Is it still necessary to perform acid washing and passivation on the stainless steel? How is this situation typically handled? . . .
Under normal circumstances, the outer surface of stainless steel does not require painting. Please verify with the user...
Does Party A require that this gas storage tank be the same color as their associated equipment and pipelines?
Yes, the requirements for use in power plants are that the color should be consistent with that of other equipment
Stainless steel generally does not require painting on its outer surface; even if painting is applied to the outer surface, it is best to carry out acid washing and passivation first.
Under normal circumstances, after stainless steel products are manufactured, acid washing and passivation are sufficient to meet the anti-corrosion requirements. If the customer requests painting, that can also be done, though it incurs higher costs.
