Continental Disc Corporation

The pharmaceutical, biotech, food and beverage industries rely on the high-precision SANITRX HPX rupture disc family – a sanitary rupture disc with the perfect combination of industry-leading performance with ASME BPE, USP Class VI and 3A compliance. The SANITRX HPX rupture disc is a semicircular, scored, reverse-acting rupture disc, capable of withstanding cycles from full vacuum to 95% of the stamped rating. It is available in 90 or 95% maximum recommended operating ratio.

We manufactured the versatile, reliable HPX-Ta from tantalum – the only suitable material for processing highly corrosive media such as bromine, chlorine, HCL, nitric acid or sulfuric acid. The HPX-Ta has a 90% maximum operating ratio and designed for a minimum of 1,000 cycles from full vacuum to maximum recommended operating pressure. It’s also a member of the HPX rupture disc family.

Push back against overpressure with the reverse-acting HPX rupture disc – your most versatile, cost-effective weapon in the battle against overpressure. Engineered to fit nearly any overpressure protection application, the HPX Rupture Disc has proven performance in excess of 5 million cycles, operating up to 95% of burst pressure, proving it the best in the industry – and the best choice for your operation. It’s also part of a larger product line of rupture discs that have proven themselves time and time again.

The pharmaceutical, biotech, food and beverage industries rely on the high-precision SANITRX rupture disc family – the perfect combination of industry-leading performance with ASME BPE, USP Class VI and 3A compliance. The SANITRX LP rupture disc includes all the features of the original SANITRX rupture disc, slightly modified for applications requiring lower pressures with reduced flow resistance.

Relieve ultra-low vacuum or positive pressure conditions with the highly accurate, bidirectional POS-A-SET rupture disc. Our double-acting design allows the POS-A-SET to do the work of two rupture discs with just one installation point. It relieves low positive pressure (as low as 1 inwc) with a girdle and knife-blade assembly on one side, while slightly higher negative pressure is relieved from the other side with perforations and a pre-cut section. Looking for the CAL-VAC rupture disc? Nearly identical to the POS-A-SET rupture disc, the CAL-VAC relieves ultra low-pressure in the negative direction – the inverse of the POS-A-SET’s ultra-low relief in the positive direction.

Liquid and gas transportation operations need the TANKSERT rupture disc – a composite rupture disc that protects railroad tank cars, over-the-road tank trucks and other vessels from dangerous overpressure conditions. The TANKSERT rupture disc is ideal for installation in standard threaded- or bolted-type safety vent assemblies on transportation vessels.

Protect intermodal tank containers, railroad tank cars and tank trucks with the ICON rupture disc – a tension-acting, cross-scored, non-fragmenting disc designed for the unique demands of liquid and gas transportation vessels. The ICON rupture disc is ideal for installation beneath pressure relief valves due to its non-fragmenting design.

The MICRO X rupture disc is a flat seat, cross-scored, tension-type rupture disc that provides a full, non-fragmenting, four-petal opening pattern. We score the MICRO X on the vent side of the rupture disc, leaving the process side of the disc perfectly smooth – and more resistant to corrosion and accumulation of process media.

A versatile line of high-performance, corrosion-resistant rupture discs, our composite discs are ideal for systems that require lower burst pressures than standard discs can provide. Our composite rupture discs consist of two or more metallic or non-metallic components. The components typically consist of a metallic top section and a metallic or non-metallic seal with optional vacuum support, protective rings, gaskets or outlet liner. This rupture disc is a 30° angular “light lip” seat, ideal for normal operating pressures. If you’re looking for superior metal-to-metal sealing, choose our composite flat seat design instead .

Need an economical corrosion barrier or environmental seal? The ENVIRO-SEAL rupture disc will do the job with excellent performance and a non-fragmenting design. The ENVIRO-SEAL is a flat seat, composite rupture disc that installs between standard bore ASME, DIN or JIS companion flanges. Use it to isolate the downstream side of low-pressure atmospheric store vessels, pressure relief valves and other equipment from corrosive environments.

If you’re looking for a 30° angular “light lip” seat, ideal for normal operating pressures, try our Standard 30˚ seat rupture disc.

Decades ago, our Standard 30° seat rupture disc was one of the first in the industry. Today, it’s ubiquitous in nearly every industry. Use the Standard 30˚ seat whenever you need reliability, low cost and simplicity. The Standard 30° seat rupture disc’s full-opening design responds within milliseconds to potentially damaging overpressure accumulation, making it ideal for a variety of protection applications.

Precision failure-initiating indent, high-precision scoring and a variety of construction materials make the ULTRX rupture disc a versatile and economical overpressure protection option. The ULTRX features the highest burst pressure rating in the TRX line of scored, reverse-acting rupture discs. Learn more about the STAR X, for ultra low-pressure applications, or the MINTRX, for mid- to low-pressure applications. Alternatively, you can see other product varieties in our popular line of HPX rupture discs.

The STAR X rupture disc has low burst pressures and includes a wide range of construction materials as well as our precision failure-initiating indent to precisely control disc buckling at exact pressures. The STAR X covers low burst pressure ratings in the TRX line of scored, reverse-acting rupture discs. Learn more about the ULTRX, for high-pressure applications, or the MINTRX, for mid- to low-pressure applications. In addition, we also offer our HPX rupture discs.

Reliable, accurate, easy to install and simple to retrofit into your current piping system – the RCS rupture disc is the clear choice for any gas-only application. A reverse-acting, cross-scored rupture disc, the RCS provides high performance pressure relief for larger sizes than available with the HPX line.
