Supplier: HMA Group

HMA Instrumentation supply industrial explosion and over pressure protection through our range of BS&B Safety Systems Bursting and Rupture Burst Disks.

Price Guide: POA

Invented by BS&B, our range of Bursting Disks and Rupture Burst Discs includes reverse buckling rupture discs, tension loaded discs, graphite disks and explosion vents providing a pressure relief solution to protect your people and your plant.

Burst pressure is accurately controlled by a combination of material properties and the shape of the disk domed structure. By loading the Reverse Buckling disk in compression it is able to resist operating pressures up to 100% of minimum burst pressure even under pressure cycling or pulsating conditions.

Designed for non fragmentation upon activation, Reverse Buckling disks are recommended for combination with pressure relief valves to isolate them from normal process conditions ensuring excellent leak tightness, reduced valve maintenance expenses and often allowing the use lower cost valve trim.
