I identified several leaks on a brand new jacketed fermentation vessel and was hoping for some input on the appropriate method of diagnosing and repairing. First, I'll explain my method of identifying the leak.
1. Pressurized vessels to 10 psi with CO2 through CIP arm.
2. Waited 5 minutes before inspecting.
3. Sprayed down all seams and weld points of tank with soapy water.
4. Found bubbles...
The leaks were coming from the welded seams on the external shell which, correct me if I'm wrong, means there is a leak on both the interior and exterior. I also removed the glycol feed line (has not been filled yet with glycol) and it was pressurized and bleeding CO2. Again, correct me if I'm wrong, but the only way this is possible is if the jacket integrity has been compromised.
We contacted the equipment manufacturer and they said they would send someone to repair. While I'm happy to hear this, I have a hard time believing they will be able to provide a quality repair without removing the exterior shell, fixing the inner layer and then replacing the exterior. Is that correct? Is there a better method of repairing that I'm simply not aware of? Any help would be greatly appreciated.
