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.
Surge resistant rupture disks (bursting discs) for railroad tank cars
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 SR-TC™ Reverse Rupture Disk (Bursting Disc) will resist overpressure surges* of 125% to 140% of the rated burst pressure for up to 0.5 seconds duration. Greater surge protection may be expected for shorter surge duration. The SR-TC™ Rupture Disk (Bursting Disc) offers extended disk service life where the disk may be subjected to 'humping" action or when rapid deceleration of an OTR trailer occurs.*The value of the over pressure surge depends on the disk's burst pressure rating.
Standard disk materials are Stainless Steel grade 316 & Inconel® (Nickel alloy 600). Other materials are available on request. All standard disks are available with 0%, 5%, and 10% manufacturing ranges.
The slotted top section is protected by a tank car ring which also ensures burst accuracy. A vacuum support prevents damage to the disk, should the disk be subjected to vacuum during unloading or while the tank car is in transit. A spacer ring is located above the FEP/P'TFE seal and the top section.
The SR-TC™ Reverse Rupture Disk (Bursting Disc) may be installed directly on to standard threaded or bolted type tank car fittings.
The BS&B global team appreciate the support of our customers and suppliers during this challenging time.
