explosion vent domed singled stainless steel Rupture Disc for big burst pressures

explosion vent domed singled stainless steel Rupture Disc for big burst pressures

The rupture disk safety device is a composite bursting disc composed of a metal diaphragm and a sealing film with a slit on the plane. Burst pressure is controlled by the weakened structure of the slits and holes in the plane of the metal diaphragm. When the system overpressure, rupture fragments along the weak link tensile damage, relief pressure.

The rupture disc has the advantages of large discharge area, good sealing, low bursting pressure, sensitive action, safety and reliability.

It's determined by the tensile strength of the material employed. System pressure is subjected to the concave side of rupture disk on normal operating condition. When excessive pressure occurs on the protected system, the dome begins to thin out and the disk bursts, providing a full relief opening.
