Flanged Bursting Discs

(Flanged Rupture Disks)

Flanged bursting discs (flanged rupture disks) are a highly effective solution for securing pressurised systems, combining low spatial requirements with fully metallic sealing surfaces. In the event of excessive overpressure, the disc ruptures at a predefined burst pressure, allowing the medium to escape in a controlled manner and protecting valves, containers and plant equipment from damage.

These units are designed for integration directly into flanged connections and can be deployed both upstream of valves and as standalone protection on vessels and process lines. The result is a compact, low-maintenance overpressure safeguard with a predictable, repeatable response.

Burst Performance & Production Quality

Precision and control during manufacturing are critical to the performance of flanged bursting discs. The use of thin, engineered foils enables us to produce discs for low pressures from 10 bar upwards, making them suitable for both low and medium-pressure applications.

Every bursting disc is subjected to 100% inspection. We verify the foil thickness and material strength to ensure that each unit achieves the specified burst pressure window. This level of process control provides consistent, reliable performance across both small and large production runs.

• Minimum burst pressure: from 10 bar (application-dependent)
• Fully metallic sealing surfaces: no soft sealing elements required
• 100% inspection: each disc tested for material strength and burst performance
• Suitable for low-pressure and medium-pressure applications

Materials, Sizes & Configurations

We supply flanged bursting discs in a wide range of material, pressure and dimensional combinations, ensuring a close fit to your specific application. Customers can specify from nickel, stainless steel or aluminium in a selection of standard sizes between 7 mm and 21 mm.

This flexibility allows us to engineer the optimum disc for almost any coupling design. To streamline integration and reduce sourcing effort, we can also supply the corresponding coupling to match the selected disc.

• Materials: Nickel, stainless steel, aluminium
• Standard sizes: 7 mm to 21 mm
• Series capability: Very small to very large production runs
• Custom matching: Discs configured for a wide range of couplings and flanged interfaces
• Optional couplings: Matching couplings available for complete system solutions

Applications

Flanged bursting discs (flanged rupture disks) are used wherever pressurised systems, containers or plants must be protected from excessive overpressure with a compact, metal-sealed device. Typical use cases include:

• Protection of pressurised containers and process vessels
• Overpressure protection in pipeline and distribution systems
• Integration upstream of safety or control valves
• General plant protection in low to medium-pressure applications

With their compact footprint, fully metallic sealing surfaces and tightly controlled burst characteristics, our flanged bursting discs deliver reliable, application-specific overpressure protection for a broad range of industrial systems.
