Note: Minimum burst pressures are applicable at all temperatures; maximum burst pressures at 72 °F (22°C). For burst pressures below JRS minimums use the type FRS or type LPS disk. For pressures above the JRS maximums, use disk types S-90, RLS, SKR and Sigma. Note: Hastelloy® is a trademark of Haynes International Inc.

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

JRS™破裂板はドーム型金属単板低設定圧力用反転型破裂板です。JRS™は設定圧力を超えると回転し、ディスクの大気側に取り付けられたティースリングに沿って破裂開口します。ダウンストリーム側のティースリングと組合わせたヒンジによりディスクの中心部の破片飛散を防ぎます。
