Dear Experts,

Kindly comment on the issue - In ISO drawing there is a blind flange coming after weld neck flange and it's included in hydro test limit too. But now hydro test crew want to use temporary blind flange instead of permanent blind flange. My question is whether i have to include permanent blind flange during the hydro test.
