Annular bottom plate replacement
Annular bottom plate replacement
(OP)
Hello
this is my first time repairing a fire water open top storage tank designed according to API 650, date of fabrication is 1987, this tank suffers from corrosion in some of the annular bottom plates (according to the inspection report, 02 annular plates are set to be changed). in order to do that , i am going to use plasma cutting technique to remove the plates. Once these plates are removed and before welding the new ones, the tank shell may suffer buckling due to its weight.
I don't have a specific question, but looking for recommendations and comments
all feedback is always welcome
thank you in advance

Perhaps you should make a call to an experienced tank fabricator.

Not sure what you are doing with your tank. I just posted this image to provide a concept for tank repair.
