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

運転中圧縮力を受けているS-90™ 破裂板 は、従来の引張型破裂板と比較して、設定圧力サイクル条件下での耐用年数が長くなります。S-90™ 破裂板は、周期圧に対し優れた疲労耐性を発揮し、設定圧力0 ~ 90%の圧力サイクルを100万回受けても問題ありません。S-90™はドーム型金属単板精密スコア溝付反転型破裂板で、設定圧力を超えるとあらかじめ弱められた十文字状のスコア溝に沿って反転開口し、完全開放します。
