Abstract:
A multi-tube differential pressure testing system for testing the differential pressure of catalyst filled tubes of tube and shell type catalytic reactors having an upper tube sheet and multiple catalyst tubes having upper ends thereof fixed to the upper tube sheet, comprising:at least one mobile support device being selectively positioned on the upper tube sheet of a catalytic reactor in pressure testing relation with a plurality of catalyst filled reactor tubes; a plurality of testing tubes being mounted to said mobile support device and being simultaneously positioned in sealed gas pressure communicating engagement with the upper ends of a plurality of reactor tubes; a pressure testing gas delivery system being interconnected with said plurality of testing tubes and communicating pressurized gas at a selected test pressure to said plurality of testing tubes and into the reactor tubes being engaged by said plurality of testing tubes; and a differential pressure monitoring system measuring the back pressure resulting from application of gas pressure at the selected test pressure to the plurality of reactor tubes being tested and having a differential pressure indicator system providing indication of the resulting back pressure of each reactor tube being tested.
