Burst disc indicator (B.D.I.): get instant notification when a rupture disc bursts

The B.D.I.® (Burst Disc Indicator) Alarm System is designed for use with Continental Discrupture discs. The B.D.I. Alarm System signals the system operator when a rupture disc has burst to relieve an overpressure or vacuum condition.

The B.D.I. Alarm System should be specified:

• When warning of pressure relief is essential for plant safety.
• When immediate notice is needed of relief of an overpressure or vacuum condition to indicate process malfunction
• When indication is vital that a rupture disc has burst and toxic substances are venting.
• When a signal is required to initiate  an automatic function, process change or shut down procedure.
• When loss or contamination of product will occur if a rupture disc is not replaced immediately
• When monitoring of rupture discs is important in hard‑to‑reach locations.

Rupture disc applications which can incorporate a B.D.I. Alarm System are limitless and found across a broad spectrum of industries and processes, and where an instant notification of an overpressure or vacuum event is required:

• Relief Valves: Isolating relief valves with a rupture disc protects internal valve parts from corrosive media. The B.D.I. Alarm System signals when a disc rupture relieves an overpressure condition, enabling the operator to correct the process and restore protection to the relief valve. Installing a rupture disc with a B.D.I. Alarm Strip on the outlet side of a relief valve notifies the operator when a valve has relieved. This is an especially important application when handling toxic or corrosive substances.
• Processing Vessels: Rupture discs with the B.D.I. Alarm System are used on processing tanks and vessels requiring protection from overpressure or vacuum conditions. The system warns when a disc ruptures.
• Chemical Reactors: When processing temperatures and pressures are critical, the B.D.I. Alarm System gives immediate warning when service is interrupted due to relief of an overpressure condition.
• Tank Transports: The B.D.I. Alarm System signals immediately when a rupture disc has burst, thereby releasing product to the atmosphere.
• Pipeline Pumping Stations: Rupture discs relieve pressure buildup in pumping stations caused by blocked pipelines. The system signals as relief occurs and can trigger shutdown of pumping systems.
• Fermentation Vessels: Products requiring gaseous blankets to prevent spoilage or product contamination must be protected from the atmosphere. Immediate warning of disc rupture permits quick corrective action, reducing loss of product and expensive gases.
• Storage/Silo Tanks: Storage tanks which damage easily from overpressure or vacuum conditions are protected with the CAL-VAC® Rupture Disc or POS-A-SET® Rupture Disc. Often these discs are located in hard-to-reach areas. The B.D.I. Alarm System warns immediately when the rupture disc bursts.
• Distillation Equipment: Distilled products must be free from contamination. Operator warning is vital when a product batch is contaminated from the intake of an outside atmosphere during vacuum relief. The B.D.I. Alarm System provides the needed warning.
