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.

概要

RLS™は周縁部に精密なスコア溝の加工された（Precision Circular-Scored）反転型破裂板です。設定圧力を超えるとドーム型金属単板反転型破裂板が、ディスクの下流側にあるあらかじめ弱められた周縁部に加工されたスコア溝に沿って反転開放します。
ディスクに溶接された特許取得済みのヒンジとの組合せによりスコア溝に沿って解放しやすくなり、高い破裂圧力においてもディスクの中心部の破片飛散を防ぎます。
