Critical zone (tank calibration)
In tank calibration reports, volume will be given for each mm of gauge height (liquid level is measured by Radar or floating level gauge or manual dip).
When the floating roof starts floating, the volume of the liquid inside the tank cannot be measured...
Hi all,
We have a pressure vessel constructed as per ASME Sec VIII Div 2 (U2 stamp) and some welding repair works has to be done on this. For repair, only R stamp is enough? or both U2 and R stamps are required?
