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.
Size, material and pressure ranges of tension loaded rupture disks (bursting discs)
Quick replacement of actives disk fast and with minimum process line exposure to personnel and the environment.
A range of sensors suitable for different rupture disk types used to provide immediate warning of a ruptured disk., #77-1003
Detec-Saf™ alarm system provides immediate warning and specific location of disk rupture and centralized monitoring of all disk locations.
The Type B Rupture Disk (Bursting Disc) is a tension-loaded forward rupture disk. The seating design allows the dome to thin out until it can no longer withstand the pressure. The metal segments fold back against the walls of the fitting in an irregular pattern to provide a full opening. The ultimate tensile strength of the metal determines its failure point when loaded in tension.
The Type B™ Rupture Disk (Bursting Disc) is available in a range of corrosion resistant materials. Standard disk materials are Nickel alloy 200, Stainless Steel grade 316, Monel® (Nickel alloy 400), Inconel® (Nickel alloy 600), Hastelloy® C-276, & Aluminum. Fluoropolymer film liners are offered with the type B™ rupture disk (bursting disc) at all burst pressures. All standard disks are available with 5% and 10% manufacturing ranges.
If backpressure on convex (atmospheric) side of the disk ever exceeds the pressure applied to the concave (pressure) side of the disk, a vacuum support may be required. Supports are not required for all disks. Consult BS&B for help. If extremely high vacuum is involved, in the micron range, seating of rupture disk (bursting disc) may require a soft gasket ring mounted to the process side of support. A ring can also be attached to atmospheric side of rupture disk (bursting disc) or vacuum grease may also be applied to the soft ring-seating surface to provide additional tightness when high vacuum is encountered.
The Type B Rupture Disk (Bursting Disc) must be used in BS&B rupture disk (bursting disc) holder types FA, SA, SF, or UA or other types recommended by and manufactured by BS&B. Substitution of either rupture disk (bursting disc) or safety head / holder not manufactured by BS&B not only may affect the burst pressure or opening characteristics of the disk, it also voids BS&B warranty.
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.
