An API 620 tank, diameter is 12000mm,design pressure is 0.02MPa, hydro test(full water) pressure is 0.025MPa and the compressure ring between the wall and roof is ok in the design condition, but because of full water hydro. test ,the compressure ring is not safe, so needa a larger size compressure ring.
Is there any other way to resolve the problem instead of modify the size of compressure ring?
