How to restore negative pressure deformation of a 2000m3 stainless steel nitric acid storage tank； The deformation is quite severe; about a quarter of it is severely deformed
With such severe deformation, it’s probably beyond repair.
Negative pressure deformation is generally difficult to handle.
Local reshaping, thermal reshaping, cold reshaping – various methods are available, depending on the specific situation
Cut off the severely deformed parts, remake the shell plates, and then reassemble them
Let’s take a look at the previous image. Repairing it shouldn’t be a problem; it’s the cost that matters.....
It certainly won’t return to its original shape.
Add reinforcement plates on the outside, then use a winch to pull it outward
It was scrapped. When we built the factory, 700 cubic meters of alkali tanks were used, and water was drained from them over night; in the end, the costs were reimbursed.
It depends on the cost of repairs; if the restoration is too expensive, it’s better to scrap it
