The Type TR™ Series torque resistant safety head option offers the identical performance and flow characteristics valued from standard BS&B safety heads. The only difference – the TR Series Safety Heads are designed with a wider seating surface to be used with metal spiral wound gaskets at the flange. This distinct safety feature protects rupture disks from situations where plant personnel may overtorque rupture disks within piping systems.
Because of the wider seating surface of the TR Series Safety Head, the load is distributed over a much broader area reducing the influence of excessive torque transmitted to the disk.
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 CSI™ disk provides a one to one damage safety ratio in a pretorqued CSR-7RS™ safety head. May be used for liquid or gas service.
