The flat slotted rupture disc is a type of rupture disc that is not pre-arched. It operates by controlling the bursting pressure through a weakened structure created by peripheral or central perforations and adjacent terminating holes. When activated, the disc ruptures along the through-holes to create a venting passage. This design ensures quick and reliable pressure relief in critical applications.
Flat slotted rupture discs (PF) are widely used in industries where organic dust is present, such as coal, mineral powder, pharmaceuticals, fertilizers, plastics, grains, pigments, and fibers. These environments can be hazardous due to the risk of dust deflagration or explosion caused by factors like mechanical friction, overheating, static electricity, or ignition sources. The rupture disc serves as an essential safety device in such scenarios.
Technical Characteristics:
- Suitable for low-pressure, no-backpressure, or vacuum applications.
- Applicable for gas, liquid, and dust media.
- Maximum working pressure can reach up to 60% of the minimum burst pressure.
