Rupture Disc KSRSR(C) Type – Safety Rupture Disc for Medium-Pressure Systems

The Rupture Disc KSRSR(C) Type is a non-mechanical safety device designed to protect pressure systems against overpressure exceeding the specified pressure limit.

The product features a Reverse Dome Scored Type (Figure C) design with an angle-activated flip/tear mechanism. When the predetermined pressure condition is reached, the reverse dome activates and the disc tears along a precisely machined C-shaped scored line.

The KSRSR(C) Type is primarily designed for medium-pressure applications and provides reliable performance under operating conditions involving back pressure, vacuum, and pressure pulsation, without requiring separate vacuum support.

With a maximum operating ratio of 90%, a maximum temperature of 593°C, and a wide selection of corrosion-resistant materials, the KSRSR(C) Type is suitable for various industrial pressure protection applications.

What Is a Rupture Disc KSRSR(C) Type?

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

Unlike mechanical relief devices with moving components, a Rupture Disc is manufactured with a predetermined rupture characteristic. When the system pressure reaches the specified Set Pressure, the disc activates and creates an opening to release excess pressure.

The KSRSR(C) Type is primarily designed for medium-pressure systems and can be used for gas, vapor, and liquid services.

Reverse Dome Scored Type – Figure C Design

The KSRSR(C) Type features a:

Reverse Dome Scored Type (Figure C)

design.

A key characteristic of this design is the precisely machined scored line formed in a C-shaped configuration on the Rupture Disc.

The scored line is precisely manufactured to control the location and rupture mechanism of the disc when the system reaches the specified Set Pressure.

The Reverse Dome structure provides reliable performance in systems exposed to:

• Back pressure.

• Vacuum.

• Pressure pulsation.

• Pressure fluctuations.

• High-temperature operating conditions.

Angle-Activated Flip/Tear Mechanism

One of the key features of the KSRSR(C) Type is its:

Angle-Activated Flip/Tear Structure

When the system pressure reaches the specified Set Pressure, the dome of the Rupture Disc reverses. This movement generates an activation force at a predetermined angle, causing the disc to flip and tear along the precisely machined scored line.

The operating principle can be summarized as:

Reverse Dome → Angle Activation → Flip/Tear → C-Shaped Scored Line → Pressure Release

The controlled rupture mechanism allows the disc to open along its predetermined scored structure when the specified pressure condition is reached.
