Stress Corrosion Cracking Question?
Stress Corrosion Cracking Question?
(OP)
I am looking at pictures of a 60 barrel fermenter for a friend.
What I am seeing is what looks to be stress corrosion cracks at the weld seams on the external jacket of the vessel.
They seem to have started from corrosion pitting.
The jacket is non-structural.
My question is...
Can these cracks be stopped, and if not will they propagate indefinitely?
My friend is interested in buying this fermenter.
Is it worth considering?

Cutting out and rewelding the area of the cracks may solve your problem or may just set it up to be repeated.
You have not provided any clues as to why stress corrosion cracking occurred in the first place. Is the material an austenitic stainless steel exposed to high chloride containing water? If so at what temperature and concentration.
Note there are records of stress corrosion cracking at ambient tempratures. refer www.nidi.org.
