Reverse Dome Scored Type Rupture Disc – Safety Rupture Disc for Medium and High Pressure Systems

The Reverse Dome Scored Type Rupture Disc is a non-mechanical safety device designed to protect pressure systems against overpressure. When the system pressure exceeds the specified Set Pressure, the Rupture Disc ruptures according to its predetermined mechanism to rapidly release excess pressure.

The Reverse Dome Scored Type Rupture Disc is primarily designed for medium- and high-pressure applications, providing reliable performance under demanding conditions such as back pressure, vacuum, and pressure pulsation.

With a maximum operating ratio of up to 90%, a maximum operating temperature of 593°C, and no requirement for vacuum support, this Rupture Disc is suitable for a wide range of industrial pressure protection applications.

What Is a Reverse Dome Scored Type Rupture Disc?

A Rupture Disc, also known as a Safety Rupture Disc, Bursting Disc, or Pressure Relief Disc, is a non-mechanical pressure safety device designed to protect pressure vessels, piping systems, and process equipment from excessive pressure.

The device is engineered with a precisely controlled rupture area. When the system pressure reaches the specified Set Pressure, the Rupture Disc activates and creates an opening to release excess pressure, helping protect equipment from damage caused by overpressure.

The Reverse Dome Scored Type is specifically designed for applications involving medium and high pressures.

Reverse Dome Scored Type Design

The Rupture Disc features a Reverse Dome Scored Type structure. The dome is installed in a reverse orientation and incorporates a precisely processed scored line on the disc surface.

When the pressure reaches the specified Set Pressure, the dome reverses or buckles. This movement activates an angle-activated flip/tear mechanism, causing the disc to tear along the precisely processed scored line.

This controlled mechanism provides fast, precise, and reliable rupture performance when the predetermined pressure condition is reached.

Angle-Activated Flip/Tear Mechanism

A key feature of the Reverse Dome Scored Type design is the following operating sequence:

Reverse Dome → Angle Activation → Flip/Tear → Precisely Processed Scored Line

When the dome reverses, the force generated at a specific angle is transferred to the scored line. The disc then tears along the predetermined line, creating an opening through which excess pressure can be released.

The precisely processed scored line helps provide controlled rupture performance and consistent operation.

Installation with FDC Standard Holder

The Reverse Dome Scored Type Rupture Disc is designed to be installed in an FDC Standard Holder.

The holder securely positions the Rupture Disc and helps ensure that the product operates according to its intended design when an overpressure condition occurs.

Using a standard holder provides several practical benefits:

• Accurate positioning of the Rupture Disc.

• Convenient installation.

• Easy replacement.

• Compatibility with various system configurations.

• Controlled installation conditions.

The actual holder configuration should be selected according to the disc size, pressure rating, connection standard, and system requirements.
