Thermal prv relieving directly back into petroleum tanks
Thermal prv relieving directly back into petroleum tanks
(OP)
At our tank farms we have prv's to relieve towards the tank. The ones closest to the tank, (across the gate valve at tank outlet) are on a bypass line which goes around the gate valve, but both ends of bypass connect to the outlet pipe (ie, one does not go directly into tank) . Any reason we cannot have that prv relieve directly into the tank, provided the tank connection meets API? We used to have a standard detail of this set-up but for some reason we do not use it any more.
Thanks
Thanks
