Product information
KSRR Rupture Disc – Reverse Dome Overpressure Protection Device
Industrial pressure systems require reliable protection against excessive pressure to ensure the safety of equipment, pipelines, and personnel. The KSRR Rupture Disc is a non-mechanical pressure relief device designed to instantly release overpressure once the system exceeds its predetermined pressure limit.
THEGIOIVAN.NET supplies genuine KSRR Reverse Dome Rupture Discs in a wide range of sizes, pressure ratings, and material options for various industrial applications.
What is a Rupture Disc?
A Rupture Disc is a non-reclosing pressure relief device that protects pressure vessels and piping systems from dangerous overpressure conditions.
Unlike conventional safety valves, a rupture disc contains no moving mechanical parts, offering several advantages:
- Leak-tight sealing
- Instant pressure relief
- Maintenance-free operation
- High reliability
- Accurate burst pressure
Once the preset pressure is reached, the disc ruptures immediately, allowing excess pressure to escape and protecting the entire system.
KSRR Reverse Dome Design
The KSRR model features a Reverse Dome Knife Type design.
Installed on a standard FDC holder, the dome is mounted in an inverted position. When system pressure reaches the specified burst pressure, the dome reverses and is cut by the knife blade mounted in the upper holder, providing rapid and reliable pressure relief without generating fragments.
Key Features
High Safety Performance
The reverse dome design minimizes material fatigue while ensuring accurate burst pressure and extended service life.
Excellent Corrosion Resistance
The KSRR Rupture Disc is available in a variety of corrosion-resistant materials, including:
- Stainless Steel
- Hastelloy
- Monel
- Nickel
- Titanium
- Tantalum
- Duplex Stainless Steel
- Special Alloys
- Aluminum
These materials make it suitable for highly corrosive industrial environments.
Suitable for Vacuum and Back Pressure Applications
Unlike many conventional rupture discs, the KSRR offers excellent performance under:
- Vacuum conditions
- Back pressure
- Pressure pulsation
No vacuum support is required.
Wide Operating Temperature Range
The KSRR Rupture Disc operates at temperatures up to:
593°C
making it ideal for high-temperature industrial processes.
