BS&B'S FEATURED PRODUCT
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 standard international flanges eliminating the need to stock unnecessary and costly inventory.
Simple, Fail-Safe Installation. The asymmetric locating pins and standard welded J-Bolt ensure correct orientation by eliminating possible human error.
Leak-Tight Bite-Type Seal. BS&B is the only disk manufacturer who machines a Bite-Type seal into the inlet flange of the Safety Head that engages the disk material proper creating a bubble-tight seal.
Easy Cleaning and Inspection. Maintenance can be done without replacing the disk due to the pretorqued cap screws, which maintain the clamping load on the disk.
For conventional pre-bulged rupture disks (bursting discs) we offer Bolted Type Safety Heads. Where space is limited and where quick or frequent change-out of rupture disk may be necessary, the Union Type Safety Head is available.
With a unique curved design, the LO-TO-FLO™ Safety Head limits process buildup to ensure superior over-pressure protection for high viscosity liquids.
Whether your process requires a Sanitary / Aseptic Fitting or a QUICKSERT™ flat-faced flange assembly holder, BS&B offers the right safety head for your application.

SKr-U Reverse Buckling Disk
The SKR-U™ rupture disk (bursting disc) is partnered with the UR-2 safety head to provide high integrity reverse buckling rupture disk (bursting disc) technology in a threaded union type holder. The SKR-U™ rupture disk (bursting disc) uses Saf™ technology (structural apex forming) to accurately control its burst pressure making it insensitive to the assembly torque variations that will occur in a threaded type holder.
