Thanks a lot. I am investigating how to decide the export oil is corrosive or non-corrosive. I was told that fully stablized oil are non-corrosive. Is that true?
What I have is:
BS&W: 0.5% target with 1.0% maximum
Sulfur content: less than 1.1% by weight
Reid Vapor Pressure (RVP): 8.6 psia...
On the oil platform, oil will be stabilized to reduce acid gases and dehydrated to a target water content to be export to onshore. The sulfur content and hydrogen sulfide may be limited also. The oil may be partially stablized or fully stabilized.
Appreciate if anyone can tell me what are the...
Thank you very much for your reply.
I have to have sound the justification for the change. Crevice corrosion of the 316L in the stagnant seawater? Do you know any historical data or regulatary info about it? Any website?
Thank you very much for your reply.
The equipment is 25 meters under seawater inside a steel basket. So I would suspect it is stagnant seawater all the time. The body consists two pieces connected using flange. The concern is the seal which is 316L. The mating pieces are low alloy CS with TSA...
It is well known that in stagnant seawater 316 may be unsatisfactory for piping. However, if I have a 316 L seal with Inconel inlay on the ring groove, will the 316 L seal has the same risk of the crevice corrosion?
An equipment made of carbon steel will be used about 30 meters under seawater. The wetted surfaces are coated and cathodically protected.
Bolts are used to connect a cap into the body. The bolts heads are exposed to seawater. One concern is that the seawater can get into bolt hole through...
