MICRO X® Rupture Disc

MICRO X® Rupture Disc

The MICRO X® Rupture Disc (Bursting Disc) is a flat seat cross-scored, tension-type rupture disc (bursting disc), and designed to provide a full, non-fragmenting, four petal opening pattern. Because the MICRO X® Rupture Disc (Bursting Disc) is scored on the outlet (vent) side of the rupture disc (bursting disc), a smooth disc surface is provided on the inlet (process side) of the rupture disc (bursting disc). The result is an undisturbed inlet surface resistant to corrosion and the accumulation of process media.


Nominal Size Range: 1" - 36" (25mm - 900mm)

Burst Pressure Range: 15psig - 3600psig (1,03barg - 248barg)

Recommended Operating Ratio: 80% of the rupture disc's rated (stamped) burst pressure.

Seating Configuration: Flat Seat

Service: Liquid or Gas

B.D.I.® Alarm System Compatible?: Yes

ASME Code Symbol Stamp Available? : Yes

Materials not indicated or shown may be available by special design. Contact the factory for more information.


B.D.I. (Burst Disc Indicator)

The B.D.I.® (Burst Disc Indicator) Alarm System is designed for use with Continental Disc rupture discs. The B.D.I.® Alarm System signals the system operator when a rupture disc has burst to relieve an overpressure or vacuum condition.

ENVIRO GUARD® Pipe End Covers

Provide protection of piping, rupture discs, and safety relief valves from unwanted foreign material, rain, insects and/or birds by specifying and installing a ENVIRO GUARD pipe end cover. The ENVIRO GUARD pipe end cover is fabricated from a tough PTFE coated/impregnated fiberglass material suitable for use in harsh environments and temperatures up to 500°F (260°C). It is available for 90° or 45° pipe ends and may be purchased with an optional retrieval rope to retain cover near the location after venting.

Heat Shield

Heat Shields are typically used to reduce the process temperature to which a rupture disc (bursting disc) is exposed. Heat Shields are used where fluoropolymer or other exotic material liners are required for corrosion resistance or as part of the rupture disc (bursting disc) itself in combination with high process temperature.
