storage tank protection

storage tank protection relief valve protection storage tanks are made from relatively light gauge materials. this limits their ability to contain pressure and, if they are emptied without proper venting, makes them vulnerable to series rupture discs provide simple, inexpensive protection against either condition.

disc size should be at least equal to the size of the flow inlet or outlet connection (whichever is greater) to the tank. maximum rupture pressure should be no greater than the design pressure or vacuum (whichever is smaller) of the tank. minimum rupture pressure should be at least 2 times the maximum working pressure or vacuum (whichever is greater) to which the tank will be exposed.

relief valve protection

corrosive elements in the atmosphere can enter a relief valve through its outlet and attack the valve's working parts. this may prevent the valve from functioning properly. valves with outlets connected to common headers are especially vulnerable. a pf series rupture disc mounted on the valve's outlet flange protects valve components from hostile environments. 

disc size should be the same as the outlet flange of the valve. maximum rupture pressure should be no greater than the set pressure of the valve. minimum rupture pressure should be at least double the maximum working pressure in the header.
