That means AISI 316 or 316L spec itself can meet the NACE MR 0103. Seeing chemical composition, the spec is more severe than MR 0103. Hardness control also is carried out normally, I don't think there are serious problems.
Sometimes, it can be contaiminated by the marine condition. I have experience to pack all of the vessel by vinyl to prevent contamination.
In addplease make sure all of the area of the vessel dried after hydrotesting. it would make the problem of contamination by concentrated chlorides from...
First of all, the corrosion rate based on literature is laboratory data. It doesn't consider the effect of protective film(like FeS as a corrosion product) and chemical injection and so on. Some data book from NACE, they recommend up to 50 mpy as a limitation. So, sometimes corrosion rate...
