(OP)
Can we have a final inspection with hydro-test before Post Weld Heat Treatment?
It could save us a lot of time and money.

"Heat Treatment. Leak tests shall be conducted after any heat treatment has been completed."
Hope this helps.

No, absolutely not. This is not a normal practice and must be avoided. Certain as-welded base materials can exhibit poor toughness in the heat affected zone region of the weld that can upon hydrotest result in failure.
