Application
Bursting Discs (or rupture discs) are used to protect plant, pipework, and vessels from high levels of overpressure and vacuum. Elmac Technologies® offers a range of bursting discs for different applications and mountings. Disc types available include forward acting, reverse acting, scored, inverted, insulated, and dual-pressure rated.

Principle of Application

Bursting Discs are non-reclosing devices that are designed to burst or rupture at a pre-determined pressure in order to relieve dangerous levels of pressure or vacuum. Forward acting discs mount with the concave surface facing the process media. As pressure increases above the recommended operating pressure, the disc will bulge until it reaches the maximum tensile strength of the material and ruptures.
