High Pressure Bursting Discs
High pressure bursting discs (high pressure rupture disks) provide a robust, passive safety mechanism for protecting high-pressure systems from uncontrolled overpressure. Designed for tightness, reliability and repeatability, these discs act as a final line of defence to prevent system damage and operational downtime.
We offer two standard formats: conical (cap form) bursting discs for extreme pressures, and flat, flanged bursting discs for medium-to-high pressure environments. Each unit is manufactured using high-integrity materials matched to your required pressure range and process media.
Conical (Cap Form) Bursting Discs
Our conical high pressure bursting discs are constructed from nickel or nickel-based alloys and engineered for operating pressures between 400 and 7,000 bar. Their cap form design works in conjunction with a cone-shaped pressure pad and a conical seat, delivering exceptional system tightness and reliable performance under extreme load.
- Pressure range: 400 – 7,000 bar
- Materials: Nickel, nickel-based alloys
- Installation: Used with cone-shaped pressure pad in conical screw connections
- Typical use: Ultra high-pressure pumps, test rigs and specialised pressure systems
Flat, Flanged High Pressure Bursting Discs
Flat, flanged bursting discs are available in nickel, stainless steel, nickel-based alloys or titanium, making them suitable for pressures below 400 bar. Installed above the pressure pad, this format offers easy access and compatibility with a wide range of high-pressure screw connections.
- Pressure range: Below 400 bar
- Materials: Nickel, stainless steel, titanium, nickel-based materials
- Installation: Positioned above pressure pad in high-pressure screw connections
- Ideal for: Medium-to-high pressure industrial systems
Applications
High pressure bursting discs (high pressure rupture disks) are widely deployed across industries where equipment protection and zero-tolerance for overpressure are operational priorities. Common applications include:
- High-pressure pumps and pump protection circuits
- Diesel high-pressure pump test benches
- Extraction systems and process equipment
- Water jet cutting plants
- General high-pressure distribution and safety systems
Custom Manufacturing & Integration
All high pressure bursting discs are produced to customer-specific dimensions and supplied with the appropriate high-pressure screw connection for either conical or flat disc formats. This ensures seamless integration, optimal sealing performance and correct burst behaviour within your system architecture.
