Rupture Disc – Reverse Dome Buckling Type for Reliable Overpressure Protection

Rupture Disc is a non-mechanical safety device designed to protect pressure systems by releasing excessive pressure when it exceeds the predetermined pressure limit.

The Reverse Dome Buckling Type Rupture Disc is designed for a wide range of industrial applications and can be used with various process media, including liquids, gases, steam, vapor, sludge, and resin.

With its unique buckling and shear-actuated design, the product provides precise rupture performance, high reliability, strong corrosion resistance, and excellent resistance to external impact.

What Is a Rupture Disc?

A Rupture Disc, also known as a bursting disc or safety rupture disc, is a pressure relief safety device used to protect pressure vessels, piping systems, and industrial process equipment against overpressure.

Unlike mechanical safety valves, a Rupture Disc has no moving mechanical components. When the pressure reaches the specified set pressure, the rupture disc operates according to its designed rupture mechanism and rapidly releases excess pressure from the system.

The Reverse Dome Buckling Type is designed to be installed directly between flanges without requiring a separate holder, providing a simple and convenient installation solution.

Reverse Dome Buckling Type Design

The Rupture Disc features a Reverse Dome Buckling Type design.

The rupture disc is installed with its dome in a reverse orientation. When the pressure reaches the specified set pressure, the dome inverts or buckles. This movement activates the control disc and its specially designed knife-shaped structure, which causes the rupture disc to shear and open.

This shear-actuated mechanism enables the disc to provide precise and reliable rupture performance when the predetermined pressure condition is reached.

Holderless Flange Installation

One of the key advantages of this design is that it can be installed directly on the flange without a separate holder.

This provides several practical benefits:

• Simplified installation.

• Reduced number of components.

• Easy handling.

• Convenient replacement.

• Reduced installation complexity.

• Suitable for various industrial piping and equipment configurations.

The actual flange and installation configuration should be selected according to the applicable product specifications and system requirements.

A high operating ratio allows the system to operate relatively close to the specified set pressure while maintaining the designed pressure protection characteristics.

The operating ratio should be evaluated together with the actual operating pressure, set pressure, temperature, and process conditions.

5. Easy Handling and High External Impact Resistance

The product is designed for convenient handling and provides high resistance against external impact.

This feature can be particularly beneficial during transportation, installation, maintenance, and replacement operations where the rupture disc may be exposed to mechanical handling or external forces.

6. Precise Rupture Performance

The specially designed Reverse Dome Buckling Type mechanism provides precise rupture performance when the specified pressure condition is reached.

This helps ensure reliable pressure relief performance and contributes to the overall safety of pressure equipment and process systems.

7. Excellent Reliability

The Rupture Disc is designed to provide stable and reliable performance in demanding industrial environments.

Its combination of reverse dome construction, shear-actuated operation, material options, and high operating ratio makes it suitable for applications where reliable overpressure protection is critical.

8. Patented Product

The Reverse Dome Buckling Type Rupture Disc is a patented product, incorporating specialized design features intended to provide improved handling, installation, durability, and rupture performance.
