Torqued Resistant Safety Heads (Holders)

Performance Features

  • For applications where safety head installation between companion flanges will use high energy sealing systems such as spiral wound gaskets
  • Designed with a wider seating surface than a standard BS&B safety heads.
  • Protects rupture disks from situations where plant personnel may overtorque rupture disks within piping systems
  • The load is distributed over a much broader area reducing the influence of excessive torque transmitted to the disk.

Standard Materials

316 stainless steel and carbon steel.

Also available Monel® alloy 400, Inconel® alloy 600, Hastelloy® alloy C and C-276, aluminum, and titanium.

Double Disk Assembly

Double disk assemblies consist of three safety head components; an inlet, a mid-flange and an outlet with a disk installed between the inlet and mid-flange. A second disk is installed between the mid-flange and outlet flange. All Sta-Saf safety heads models are available as double disk assemblies.

Double disk assemblies are available with the TR™ torque resistant option.

Accessories

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.

Saf-T-Change Quick Disk Replacement (QDR)

After activation, the replacement disk is quickly slid into place. Saving hours of lost production due to blown rupture disks.

Tell-Tale Assemblies & Excess Flow Valves/Gauges

A gauge tap in the outlet flange of the safety head may be considered when the safety head is installed in a vertical position.

Spare Safety Heads & Cap Screws

Jackscrews

When activated, the jackscrews effectively separate the flanges, providing adequate clearance to remove or insert a safety head and external gaskets.

Lifting Lug Eye Bolts

Eye bolts are recommended when weight and/or accessibility is a factor in lifting safety heads.

Baffle Plate

When a safety head is free-vented to atmosphere, a baffle plate may be considered to disperse overpressure and absorb recoil.
