Kindly give me a calculation of plate thickness to be used for hydrostatic test..

As BigH suggests, if you have a flanged connection, a blind flange will already be sized for your pressure application according to the flange class and the pipe class. If you are just using a blocking plate, get someone local to help you as it will entail thickness design and weld design.

it would be valid only for a shop test - but then the final hydro reqmt is still not met.
A operational pressure test with the operating fluid is OK to accept a bolted (flanged) joint if the piping system welds have been hydro'ed, but the higher hydro test is required for your butt-welded joints at some point in time. Or a 100 percent X-ray. Or both - depending on your insurance/pressure/temperature. HP/HT Steam, LT/HP main feed water, LT/LP/flammable turbine lube oil, and low temperature low pressure condensate water will have different requirements when new pipes are added.

The reason I need the calculation is because we need to fabricate blind flange from the steel plate.
