FSDIFULP rupture discs are composite conventional 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 This disc has been designed to be
mounted between flanges. It is excellent for use with gas and liquids in
static conditions and excellent for low pressures. FSDIFULP discs react
to excessive pressure with total opening in a few milliseconds. They
are therefore recommended for valve protection. Supports may be provided
for vacuum or counter-pressure protection. Composite rupture discs may
also be used for simultaneous protection from pressure and vacuum.
