Waterjet Cleaning for Coating Removal
Waterjet Cleaning for Coating Removal
(OP)
If high pressure water jet, 40 k psi, is used to clean the coating inside crude oil storage tank, the metal yield stress is 36 k psi, does this high pressure cleaning affect the weld/metal hardness (say 225 HBN after welding)? does the tank weld hardness have to be maintained the same after welding?
Thanks for your inputs.

But note that in normal sandblasting, the abrasive used is harder than the steel with no ill effects.
