Tank Alteration/Modification
Tank Alteration/Modification
(OP)
Hi
We are planning to add a 6"- 12" repad on the floor of a self supporting conical roof water storage tank. A point load will be connected at that location, away from critical heated affected zone. Do we need to conduct hydrotest after that. As per 9.3.3, pad can be added complying with NDE requirements but checking section 12, hydrotest not required, i could not find a strong reference that hydrotest is exempted.
Thanks,

Personally I wouldn't request a hydro for adding a welded pad on a tank floor

As this is not a major repair we may not need rehydhydro.
