Logo Forward acting disks

Product description

Forward acting, or conventional rupture disks (bursting discs) have been a mainstay in process applications since BS&B developed the first rupture in 1931. Developed in 1934, the Type B disk, the "granddaddy" of all rupture disks (bursting discs) is still the disk-of-choice in many applications.

Applying load to the concave side, the disk is subjected to tension forces. Forward acting disks regulate burst pressures by the tensile strength of the material.

For low burst pressures, the Type D disk has a slotted metal top section and a metal or fluorocarbon seal. For higher operating ratios, the scored NU-SAF family of disks is often selected for polymerization processes. Our VAC-SAF line offers protection from excessive vacuum or overpressure.

For tank car applications, the ITC disk protects intermodel tank containers while the SR-TC is a surge resistant disk for railroad took cars and over-the-road trailer service industry.

A wide range of standard rupture disk (bursting disc) assemblies is available for your specific application. These Threaded and Welded Assemblies are discarded after disk rupture. Customized designs are available for customer applications that cannot be met using standard assembly designs.

Product categories

All products offered by this exhibitor

Sensors and monitors

Alert Sensors® provide immediate warning of a ruptured disk when used with a BS&B Burst Disk Monitor or other suitable electrical monitoring equipment. When a disk or vent ruptures, the process flow through the device causes the sensor's conductive circuit to break. The disruption of the current flowing ...read more

Safety Heads

Many designs and types of fittings are used as holders for rupture disks (bursting discs) and are fabricated from metal(s) compatible with the process media and atmospheric environment. Each BS&B safety head is designed for optimum safety and performance. - Reduced Inventory Costs. One head fits most ...read more

Graphite disks

BS&B manufactures each graphite rupture disk (bursting disc) from a pure block of graphite. By impregnating the porous graphite with resin, you can be assured of a product that can withstand almost any aggressive chemical attack. Our manufacturing process achieves: - Wide range of sizes from 1/2" (12mm) ...read more
