Rupture discs

Bursting discs are a reliable safety element used to protect against overpressure or underpressure in industrial facilities.

They most often provide protection for containers, tanks and reservoirs from deformation. Thanks to the precise calibration of the burst pressure and the quick reaction in the event of a burst, they enable optimal operational safety and minimize downtime.

Thanks to the wide range of designs of rupture discs, we can offer safety solutions for a wide range of applications.

Bursting discs are safety elements that are used in pressure systems and devices as protection against overpressure and/or underpressure.

Their basic operation is the same as that of safety valves. The fundamental difference is that once the rupture discs react to the pressure difference they are exposed to and open, they cannot be closed again (they must be replaced if they open).

Normally, rupture discs consist of an assembly that includes a special housing (diaphragm holder) and, if necessary, other components such as: vacuum support or back pressure support, reinforcing ring, rupture indicator, etc.

Rupture diaphragms are sealing devices, designed so that their opening occurs by rupture of the diaphragm at a predetermined pressure value.

There are different types of rupture discs. They are made of metal materials, PTFE or graphite. They cover a wide range of sizes, pressures and working temperatures.

Bursting discs have numerous advantages:

They are often a more economical solution compared to other pressure relief elements (especially when expensive materials or large cross-sections are required).

They are available in a wide range of sizes, materials and calibration pressures.

They have low maintenance costs.

They have no moving parts, so they guarantee shorter reaction times than other safety pressure elements.

They ensure an excellent level of tightness of the system, thereby reducing the risk of leakage of toxic, hazardous or rare substances.

Thanks to them, the safety valve can be isolated from corrosive or otherwise degrading liquids.
