FSLPDULP - Ultra Low Pressure Rupture Discs

FSLPDULP model discs are a simple, reliable, accurate and economical solution for applications requiring extremely low pressure protection (positive or negative). Their primary use is to protect processing and storage tanks, atmospheric vessels and silos with low design pressures, and therefore only able to withstand slight pressures and vacuums, against implosion or rupture. A specially interesting application is in the protection of biogas digesters. FSLPDULP rupture discs are flat composite discs formed by four parts: a slotted, perforated metal part a seal membrane (usually in PTFE but also available in many other metallic or non-metallic materials) a protection section a calibration ring with blades to improve membrane rupture FSLPDULP discs open without fragmentation to prevent product contamination and can be customised to meet a broad range of non-standard specifications and applications. FSLPDULP discs can be designed: for dual pressure and vacuum protection to resist vacuum or counter-pressure
