LOTRX® Rupture Disc

LOTRX® Rupture Disc

The LOTRX® Rupture Disc (Bursting Disc) represents a breakthrough in rupture disc (bursting disc) design. The LOTRX® Rupture Disc (Bursting Disc) provides all the benefits of Continental's scored, reverse acting discs, with additional features that make it ideal for extremely low pressure applications.

The LOTRX® comes enhanced with features such as the Failure Initiating Indent, which lowers the pressure at which reversal occurs, and the Notched Outlet Ring, that facilitates opening of the rupture disc (bursting disc) along the precision semicircular score at extremely low reversal pressures.


Nominal Size Range: 1" - 8" (25mm - 200mm)

Burst Pressure Range: 1.5psig - 40psig (0barg - 2barg)

Recommended Operating Ratio: 90% of the rupture disc's rated (stamped) burst pressure.

Seating Configuration: Flat Seat

Service: Gas

B.D.I.® Alarm System Compatible?: Yes

ASME Code Symbol Stamp Available? : Yes

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.
