Tank Built in date - 1982
The Size of Breather Valve (Pv Valve) 4inch Quntity-01.
As per API 2000 7tH Edition 2014, we verify that for volatile liquids, the out-breathing calculation is simply double,
and calculated Breather valve size is coming 6inch,
Technical query,
i want to know that the API 2000 7tH Edition 2014, is implemented in existing tanks which have built in before API 2000 7tH Edition 2014.
Thanks and Regard,
