Dear All

I am dealing with a vertical pressure vessel which its top head is in type of blind flange. During operation we understood that it is better to consider a vent branch on top of vessel. Inside diameter of vessel is about 1000 mm , design pressure is 10 barg and there is no opening on blind flange at this moment.

I want to know can we make an opening hole on mentioned blind flange (say 1/2") to insert a piece pipe/valve for vent branch ?

RE: to make an opening on a pressure vessel blind f

Sure you can do that, but you'll have to satisfy the code and regulation under which the vessel is built.
