BS&B Reverse Buckling Technology
The Reverse Buckling disk represents the best in rupture disk (bursting disc) technology. Invented by BS&B, our range of reverse buckling products provides a pressure relief solution for burst pressures ranging from a few inches of water column / a few millibar to over 70,000 psig / 4800 bar.
For mer informasjon:
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.
The Sta-Saf® System includes 11 reverse buckling rupture disk models. These rupture disks offer the optimum performance attributes consisting of high operating margins, excellent resistance to cycling and pulsating service, and overall serviceability in demanding process environments.
The selection of the appropriate rupture disk from the Sta-Saf family is determined by specifications and requirements of the application.
