Composite bursting disc – Multilayer (stainless steel / PTFE / stainless steel) built up metal bursting disc for direct installation between flanges (without bursting disc holder). Composite bursting discs are mainly flat bursting discs used for low to medium / static pressures. Depending on the design, composite bursting discs can be vacuum-resistant or may safeguard different degrees of high pressures in excess and low pressure directions. As a supplement, flat composite bursting discs can be fitted with inductive burst monitoring.
Concave bursting disc – Forward acting, arched bursting disc with the pressure being directed against the concave side
Convex bursting disc – Pressure-loaded, arched bursting disc (also known as “reverse acting rupture disc”) with the pressure being directed against the convex side
