Abstract
A bursting disc assembly has a bursting disc and an outlet side support ring. In order to provide a safety warning, when the bursting disc assembly is incorrectly installed in a reversed orientation, the outlet side ring has a passage through it from its radial interior to its exterior, in the form of a full thickness slot or a groove. In an incorrect installation, this passage provides a leak path from the pressurized side of the disc.
Claims15
A bursting disc assembly comprising:
- a bursting disc adapted to rupture at a predetermined pressure differential, the bursting disc having an inlet face and an outlet face, and
- an outlet side support ring adapted to fit on the outlet face of the bursting disc, having a first face to oppose said outlet face of the bursting disc and a second face on its opposite side from said first face, said outlet side support ring having a fluid passage through it from its radial interior to its radial exterior, wherein said fluid passage is selected from a full thickness slot from said first face to said second face and a groove in one of said first and second faces,
- wherein when said first face of the outlet side support ring is pressed in its assembled state against said outlet face of the bursting disc, said fluid passage provides a fluid flow path located within a thickness of said outlet side support ring and extending from the outlet side of the bursting disc to the radial exterior of said outlet side support ring.
An assembly comprising:
- a vessel which is pressurised in use, and
- a bursting disc assembly mounted in an outlet of said vessel, said bursting disc assembly comprising
- a bursting disc adapted to rupture at a predetermined pressure differential, the bursting disc having an inlet face and an outlet face, and
- a support ring supporting the outlet face of the bursting disc, having a first face to oppose said outlet face of the bursting disc and a second face on its opposite side from said first face, said support ring having a fluid passage through it from its radial interior to its radial exterior, wherein said fluid passage is selected from a full thickness slot from said first face to said second face and a groove in one of said first and second faces, and
- wherein when said first face of the outlet side support ring is pressed in its assembled state against said outlet face of the bursting disc, said fluid passage provides a fluid flow path located within a thickness of said outlet side support ring and extending from the outlet side of the bursting disc to the radial exterior of said outlet side support ring.
