The LP Series Prebulged Rupture Discs are specially designed safety devices that provide reliable overpressure protection in various industrial applications. These rupture discs are characterized by their prebulged design, which enhances their ability to handle higher pressures and ensures predictable performance under challenging conditions.
Ideal for isolating safety relief valves.
Up to 95% of the marked burst pressure, offering long service life.
Suitable for liquid, gas, or two-phase systems.
Operates without needing vacuum support, withstanding full vacuum conditions.
Available in a wide range of standard and exotic materials, including SS316L, Hastelloy, Nickel, Inconel, Monel, and Tantalum.
Covers sizes from 25 mm (1 inch) to 150 mm (6 inches).
Multi-layer construction for corrosive materials and PTFE liners or coatings.
Can be delivered at short notice, including urgent sets of three rupture discs.
