Hi Cloa,
Operation temp is 42degC ~ 128degC with non-corrosive fluid inside.
No detail information is there for other queries.
We just want to verify whether no SCC occur at backside of bottom plate by soil.
Stainless Steel Tank is suspected to have External SCC at backside of bottom plate.
Is there any effective NDT method without stopping operation?
(UT from annular plate, etc...?)
