Dear freinds,
Attached is image taken from the inside of a crude oil stabilizer column during the turnarrond inspection. The image is showing crack in the plate of the column made of 316L stainless steel . This is the second inspection we are facing such problem and each time we are welding the cracks with out chaging the damaged elements.
We are suspecting a chloride stress corrosion cracking to be the main cause of the cracks because the stabiliser is located just down stream the dessalter . I want your expert opinion on the problem in order to pin point clearly the true cause. If so what are the suitable solutions to be implimented .
Regards
