Such tie in welds which cannot be hydrotested are tested with 100% radiography (preferebly) or any other NDE as accepted by client. Such welds are called "Golden Welds"
As we have seperate piping codes (31.3 or 31.1 etc) Section VIII is applied to piping at very few instances

But what about the tie in joints which are not able to be hydrotestd..100% NDE is ok for that.

<Maybe the piping codes are different, but Section VIII doesn't permit welding after the hydrotest.
