Forward-explosive or conventional rupture discs, first developed by BS&B in 1931, became the basic rupture disc used in process applications. The Type B disk, developed in 1934, is considered the "grandfather" of all rupture disks and is still the disk of choice in many applications.
By applying a load to the concave side, the disc is subjected to tensile forces. Forward moving discs regulate burst pressures by the tensile strength of the material from which they are made.
For low burst pressures, the Type D disc features a slotted metal top and a metal or fluorocarbon seal. For higher operating classes, the NU-SAF disc family is often chosen for polymerization processes. The VAC-SAF series, on the other hand, provides protection against excessive vacuum or excessive pressure.
For tank car applications, the ITC disc protects modular tank containers; The SR-TC is a surge disc for rail and is used in the on-board trailer service industry.
A wide range of standard rupture disc assemblies are available for your specific application. These threaded and welded parts are discarded after the disc bursts. Custom mounting designs are available for customer applications whose needs cannot be met using standard mounting designs.
