What are the anti-corrosion painting standards for stainless steel in pressure vessels? SH/T3022-2019 does not contain any relevant provisions
For stainless steel materials, acid washing of the surface is sufficient; it is more durable than paint
It depends on the working conditions; the standards are fixed. Ignore the ads and focus on the actual efficacy. Stainless steel is not resistant to chloride ions, so corrosion protection is required
Anticorrosion treatment is only applied to stainless steel equipment that is buried underground; pickling and passivation are done for those that are not buried
These days, many projects along the coast and at sea require stainless steel to be painted; the pre-treatment requirements vary, while the coating system is similar to that used for carbon steel, with restrictions on halogens
