BS&B supplies many of the accessories required to safely and conveniently install our overpressure relief devices and complementary products. Through our professional team and global network of sales engineers and procurement personnel, we are able to provide the highest quality accessory products to meet your installation requirements.
After activation, the replacement disk is quickly slid into place. Saving hours of lost production due to blown rupture disks.
A gauge tap in the outlet flange of the safety head may be considered when the safety head is installed in a vertical position.
When activated, the jackscrews effectively separate the flanges, providing adequate clearance to remove or insert a safety head and external gaskets.
Eye bolts are recommended when weight and/or accessibility is a factor in lifting safety heads.
When a safety head is free-vented to atmosphere, a baffle plate may be considered to disperse overpressure and absorb recoil.

The SKr™ Reverse Rupture Disk (Bursting Disc) is designed with a circular score line located at the edge of the domed area, on the downstream side of the disk. At the marked burst pressure, the disk's dome reverses and opens by shearing around the circular score line. The SKr™ Reverse Rupture Disk (Bursting Disc) uses SAF- technology (Structural Apex Forming) enabling very low burst pressures to be achieved with excellent opening characteristics. An integral energy absorbing hinge located on the downstream side of the disk enables the SKr™ Reverse Rupture Disk (Bursting Disc) to perform in gas or liquid service with superior flow performance. The hinge design interacts with the Safety Head bore to retain the SKr™ Reverse Rupture Disk (Bursting Disc) on opening, avoiding fragmentation
The SKr™ Reverse Rupture Disk (Bursting Disc) is available in 316SS, Nickel Alloy 200, Monel Alloy 400, lnconel Alloy 600, Hastelloy Alloy C276, Titanium and Tantalum. A competent person should select the disk material that is chenmically resistant to the application. Corrosion of the disk material will affect its performance and may result in premature bursting or leakage through the disk. All standard disks are available with 0%, 5%, and 10% manufacturing ranges. For assistance in disk material selection contact BS&B Safety Systems, Inc. or BS&B Safety Systems Ltd.
The SKr™ Reverse Rupture Disk (Bursting Disc) has been specifically developed to produce superior flow performance at all burst pressures in gas or liquid service. The circular score on the disk's dome, coupled with the non-restrictive hinge on the outlet side of the disk, ensures an excellent pressure relief opening.
Flow Resistance Factor Kr may be used to determine the relieving capacity of a system according to the ASME and CEN (pending) codes. Individual Kr values have been established for both gas and liquid service for the SKr disk. Minimum Net Flow Area (MNFA) for each disk size is provided to assist with ASME sizing calculations. Net Relief Area (NRA) for each size disk is provided to assist with European code sizing calculations.
The SKr™ Reverse Rupture Disk (Bursting Disc) installed in an SRB-7RS™ Safety Head permits the correct torque to be applied in the workshop before installation into the process. The asymmetric locating pins ensure centering and orientation of the disk within the Safety Head. The performance-proven metal-to-metal 'bite type' seal in the Safety Head (2"/50mm size and above) assures a leak tight assembly. When installed properly into the SRB-7RS™ Safety Head, the assembly can be removed, inspected, cleaned carefully then reinstalled without replacing the disk as the pretorque capscrews maintain the clamp load on the disk.
All of the BS&B global manufacturing locations are processing and shipping orders with our supply chain of parts, raw materials, and services continuing to meet and exceed expectations. We continue to implement policies at each location to meet evolving local requirements for the protection of our employees in their work on your safety product requirements which are critical to the support of local, national and global infrastructure. Our customers have made a partnership with BS&B which all of our employees take very seriously as we attend to continuity of supply alongside the essential focus on safety and reliability which is a hallmark of BS&B.
Our global infrastructure continues to be developed with MS Teams now augmenting our already robust global communication platforms which provide seamless customer attention whether we are working at a BS&B facility or working from home to meet local conditions. Adapting to ‘low contact’ customer support still includes customer site visit capability with appropriate advance clearance for all parties.
As a reminder of BS&B’s capabilities, we are renowned for rupture disk devices, industrial explosion protection equipment, and custom engineered rupture disk devices, and additionally have a comprehensive line of relief valve, flame arrester, and tank vent products for both established and new applications.
BS&B can always be contacted through our web sites which include www.bsbsystems.com and www.bsb.ie.
The BS&B global team appreciate the support of our customers and suppliers during this challenging time.
