Donadon LPD rupture disc is a composite conventional disc formed by four parts:
• A slotted, perforated metal part
• A professional seal membrane (usually in PTFE)
• A protection section
• A calibration ring with blades to improve membrane opening
Designed to protect processing and industrial storage tanks, atmospheric vessels and silos against implosion or overpressure conditions.
It reacts to over-pressure in a few thousands of a second with total opening and without fragmentation.
LPD discs are a simple, reliable, accurate and economical solution for applications requiring extremely low positive and/or negative pressure protection.
Their primary use is in storage tanks with low design pressures in applications where contamination is unacceptable.
Donadon SDD model LPD discs offer non-fragmenting opening and avoid product contamination.
LPD discs may be installed directly between flanges avoiding the requirement for holders with blades and can be offered to meet a broad range of non standard specifications and applications.
LPD discs can be provided with:
• Dual protection (vacuum / pressure)
• Vacuum / counterpressure support
• Burst detector, ATEX approved, giving immediate indication of burst occurrence
