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 pressurised side of the disc.
