CDC Spezial Rupture Disc Holders

Established in 1965, Continental Disc Corporation is a leading manufacturer of rupture disc (bursting disc) devices for a variety of process industries, including chemical, petrochemical, petroleum refining, pharmaceutical, beverage, food and dairy, aerospace, gases, electronics, and other markets worldwide. Continental Disc Corporation is committed to providing the products, services, and quality you expect from the leading overpressure safety company.

Double Disc Assembly

Characteristics: The Double Assembly places two rupture discs (bursting 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).


Rupture Disc Holders for Sanitary Applications

Characteristics: The Sanitary Rupture Disc (Bursting Disc) Assembly is specifically suited for a wide range of process applications where product purity and corrosion resistance are required. The Sanitary Fitting Assembly is used in dairy, pharmaceutical, food processing, canning, cosmetic, chemical and many other industries.

Dimensions: 1“ – 10“ (25 mm – 250 mm) Material: stainless steel 316, 316L, HASTELLOY®C, MONEL®, INCONEL®

UNISERT® Assembly for Flat Seat Rupture Discs


Continental Disc Corporation's UNISERT® Assembly is a flat seat rupture disc (bursting disc) holder which provides improved rupture disc (bursting disc) sealing capabilities. It is designed to house either the MICRO X® Rupture Disc (Bursting Disc) or the Composite Flat Seat Rupture Disc (Bursting Disc). These non-fragmenting-designed rupture discs (bursting disc) provide a wide choice of burst ratings from the low pressures of the Composite (FS) Rupture Disc through the higher pressures of the scored positive-actingMICRO X Rupture Disc (Bursting Disc).

Dimensions: 1“ – 36“ (25 mm – 900 mm)

Material: Steel, Stainless steel,….
