Double Disc Assembly


Continental Disc Corporation's Double Disc Assembly places two rupture discs, either tension type or reverse acting, in series. This provides a number of potential benefits, including a zero-leakage redundant system (a gauge in the midflange would indicate any leakage, which would be contained by the second rupture disc) or a quick-opening device (where a pressurized midflange would maintain the rupture discs until the midflange pressure is dumped and differential pressure opens both rupture discs).

(B.D.I.) Burst Disc Indicator

Continental Disc Corporation's Burst Disc Indicator (B.D.I.) Alarm System is designed specifically for use with C.D.C. Rupture Discs. Upon disc rupture, the Burst Disc Indicator strip is severed, disrupting the flow of electric current through the strip. An attached alarm monitor can then transmit a warning and/or activate appropriate equipment.

Enviroguard Pipe End Covers

Protect free vent rupture disc piping and safety relief valve outlets from unwanted foreign material, rain, insects or birds by installing the ENVIRO GUARD pipe end cover. 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.

More Information

Heat Shield

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