Rupture Disc AccessoriesHeat Shield
Where process temperatures climb to levels your rupture disk or its lining material are unable to withstand, you need a CDC heat shield. The shield functions as a barrier, reducing your rupture disc's exposure to high temperatures. It restricts the continuous flow of high-temperature gases or vapors, allowing the piping between the shield and rupture disc to act as a heat sink.Continental Disc Corporation -

Burst Disc IndicatorsBDI-FLX Burst Disc Sensor System
The BDI-FLX Burst Disc Sensor System provides instantaneous notification of a burst rupture disc. When combined with an alarm monitor, this system protects lives, equipment and the environment. Designed for use with ASME and DIN flanges or sanitary applications, the BDI-FLX employs a sensor strip with a flexible potentiometer (an electrical component that varies resistance in response to deflection) to signal a burst disc.Continental Disc Corporation -
Burst Disc IndicatorsMTB-700 Alarm Monitor
A critical component of a complete Burst Disc Indicator (BDI) Alarm System, the MTB-700 Alarm Monitor links to as many as four ruptured discs to alert your nearby control room of ruptured discs. Upon disc rupture, the MTB-700’s intrinsically safe galvanically isolated barriers activate signals or output relays to warn operators and actuate pumps, valves or other equipment connected to the system.Continental Disc Corporation -
Burst Disc IndicatorsBurst Disc Indicator Alarm System
Reduce downtime, increase efficiency and ensure the safety of your facility with the BDI (Burst Disc Indicator) Alarm System. When an overpressure or vacuum condition causes a disc to rupture, the BDI immediately sends a signal to the control room to alert the system operator. The heart of the Burst Disc Indicator Alarm System is the BDI Alarm Strip. When a disc ruptures, it severs the electrically charged strip, opening the circuit and signaling the control room. We've developed an optional alarm monitor system to notify operators or activate appropriate equipment.Continental Disc Corporation -
Specialized Rupture DiscsExplosion Vent Panels
Our explosion vent panels provide instantaneous overpressure protection for nearly any type of pressurized dry-bulk handling and storage equipment. The vent panels are designed to allow a full and immediate opening to minimize structural or mechanical damage by expanded gases from the combustion of dust, gases or mists inside equipment, rooms, buildings or other enclosures.Continental Disc Corporation -

Learn more about blasting caps
What is a blasting cap?
A bursting diaphragm is a reliable safety solution to protect industrial facilities against overpressure and vacuum. The component consists of a thin metal diaphragm designed to burst at a precisely predetermined pressure.
Rupture discs are widely used in piping systems, tanks and process equipment in the chemical, energy, food and pharmaceutical industries, among others. They are available in several dimensions and pressure classes, making them adaptable to many different applications.
How does a blasting cap work?
The bursting diaphragm acts as a passive protection that is activated when a critical differential pressure is reached. When the diaphragm ruptures, the system is immediately relieved and the risk of damage to equipment or leakage of hazardous media is minimized. Since the rupture disc has no moving parts, opening takes place in a few milliseconds and the function is both predictable and stable over time.
Advantages of blasting plates
Bursting discs offer several advantages over traditional safety valves in the right applications. They provide very fast and accurate pressure relief and are completely tight during normal operation, preventing unwanted leakage.
The simple design means minimal maintenance and a long service life, often several years without the need for replacement. In addition, rupture discs are a cost-effective solution that can be used with gases, liquids and mixed media in a wide range of industries.
