RE: Breather valve replacing Frangible Joint

A suitably sized pressure (or pressure/vacuum) relief vent per the requirements of API 2000 for emergency venting can replace a frangible roof joint. Be sure to advise your client of all pertinent information related to the vent. Reference 5.8.5.3 of API 650.

RE: Breather valve replacing Frangible Joint

'Breather Valve' will have to be quite large. Look at an 'Emergency Vent' installed in the roof manway. Easy way to achieve the required diameter.
