Protective treatment for bare carbon steel
Protective treatment for bare carbon steel
(OP)
Three vessels will be shipped oversea after hydrotest.
There are the uncoated carbon steel internals in these three vessels.
I worry that the internals can be corroded during sea transportation and storage. I expect that the vessels will be serviced after 6 months later.
Could any one recommend the protective treatment on surface internals from corrosion, in case that N2 purge is not avaiable?

It is best to make a personal contact as they have a number of different approaches.

does a slight coating of oxidation matter?
use of a nitrogen blanket is pretty much standard. where that is not chosen some are using "shrink wrap".
RE: Protective treatment for bare carbon steel
Mr. eyec, could you explain "shrink wrap" in detail?
It sounds a cousin of food wrap.
If hydrotest will be undertaken with alkine water, is it possible for the carbon steel internals to be passivated?

In addition, all connections should be plugged or have flanges with gaskets.
If the light oil solution is not acceptable to you then the next solution would be to pressurize with nitrogen.
Shrink wrap is usually reserved for smaller items like control panels.

the generator was shiped via boat and train and looked good when it arrived. haven't seen it in a while but after sitting on a rail spur for a couple of months it was still nicely covered.
