Normal and emergency relief venting and vent piping for pressure vessels should be adequate and in accordance with the design of the vessel.
ASME Boiler and Pressure Vessel Code for Unfired Pressure Vessels
8 CCR Chapter 4, Subchapter 1
Pressure relief valves must be plumbed on any pressure vessel that have unobstructed contact with the pressurized substance.
Pressure relief valves must be set to a maximum of pressure (minus 50 psi for best practice) for relief at the maximum working design pressure of the lowest-pressure-component in any pressurized vessel and piping system.
