Flat Slotted Lined Bursting Disc / PF

Bursting discs consist of a flat disc with termination holes (or slits) and a sealing film. When the protected pressure system is subjected to overpressure, the bursting disc stretches along the weak area between the adjacent termination holes on the flat disc, which causes it to undergo plastic deformation. Eventually the disc ruptures at the set pressure, releasing the excess pressure and protecting the pressure-bearing equipment.

Parameter characteristics

Suitable for three types of media: gas, liquid, and dust.

Suitable for low pressure conditions.

The maximum working pressure can reach 50% of the minimum bursting pressure.

Poor fatigue resistance. It requires support when used under back pressure or vacuum conditions.

This bursting disc is widely used in occasions where dust explosions may occur.
