API 2000 7tH Edition 2014 Implementation

[engineermian]

Dear Expert,i required your support to clarify the implementation of new code API 2000 7tH Edition 2014, The detail of issue is,

 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 SABIC existing tanks which have built in before API 2000 7tH Edition 2014.

Normally the Code does not apply retroactively, but there may be exceptions and companies who look at the subject in a different way. You should talk to the Engineering department in SABIC and see if there is any procedural way of evaluating cases like this.
