The convex of reverse acting rupture disc is on the high pressure process side. When the metal disc is compression-loaded, the disk reverses and bursts along the prescored line to relieve pressure.
Note: Types and Specifications of Safety devices need to be calculated and selected according to the specific working conditions of the protected equipments and systems before quotations.
Technical features
• Non-fragmentation design
• Operating ratios up to 90% of the low end of burst tolerance
• Disc design offers high cycle life(compared with forward acting rupture disc)
• Suitable for gas service only
• Standard manufacturing design range and total tolerance ensures marked rating on disk tag does not exceed the MAWP of equipment
• Withstand full vacuum without additional support
• Wide range of standard and exotic materials available
• Sizes from 25mm to 600mm
• Burst ratings from 2barg to 70 barg
• Resisting product build-up. The smooth convex side of the disc is exposed to the process media
• Use of rupture discs in series with safety valves
• 3-dimensional stainless steel tag engraved with complete disc specifications
Options
•Fluoropolymer liners or coatings
•Burst Indicator
*Note: The maximum temperature rating of rupture disks supplied with liners and BI is lower than the base disk material.
Protection of Safety Relief Valve
• When a disk is mounted under a Safety Relief Valve, the working components of the valve are isolated from hostile environments.
• Tell-Tale Assembly:Pressure Gauge,Tee,Excess Flow Valve,Tube
