Precision failure-initiating indent, high-precision scoring and a variety of construction materials make the MINTRX rupture disc a versatile and economical overpressure protection option. MINTRX burst pressures are in the mid-range of the TRX line of scored, reverse-acting rupture discs. Learn more about the ULTRX, for high-pressure applications, or the STAR X, for ultra low-pressure applications. Alternatively, learn more about our popular line of HPX rupture discs.

A breakthrough in rupture disc design: the LOTRX rupture disc. The LOTRX rupture disc has all the benefits of our scored, reverse-acting discs, and more — a failure-initiating indent to lower the pressure at which reversal occurs and a notched outlet ring to facilitate opening of the rupture disc along a precision semicircular score — making it the perfect solution for extremely low-pressure applications.

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 LPX rupture disc is a stainless steel, semicircular scored, reverse acting rupture disc designed for sanitary gas applications that require pressures below SANITRX HPX.

The Continental Disc HPX-CTG™ cartridge rupture disc addresses the need to minimize potential leak paths in chemical applications. The welded rupture disc cartridge assembly, built with HPX® technology, seamlessly integrates between traditional flange connections. By eliminating the need for a separate holder, the welded design significantly reduces the risk of leaks compared to conventional rupture disc systems. As a seal-welded version of our HPX rupture disc, the HPX-CTG ensures a leak-tight assembly, making it ideal for applications involving toxic or hazardous media or where emissions regulations are a concern. With the proven durability of the HPX rupture disc — type tested to five million cycles — the HPX-CTG enhances safety and reliability while minimizing emissions risks in critical applications. The single-piece HPX-CTG assembly simplifies installation and minimizes the risk of damaging the rupture disc during installation and handling. Its fully welded design eliminates torque sensitivity, alleviating concerns about inconsistent torque application and the higher torque required for certain gaskets, ensuring a more reliable and flexible installation.

The Continental Disc APX™ rupture disc is a semicircular scored reverse acting rupture disc that is ideal for liquid or gas/vapor applications. In terms of performance, precision, and durability, the APX rupture disc outperforms the competition. One of several benefits of the APX is the flexibility to tailor it to the demands of the customer, particularly regarding flexibility in holder materials of construction. Designed for use in toxic and corrosive environments, the APX rupture disc combines Continental Disc’s rupture disc performance with materials that stand up to the most challenging process media. The APX continues the legacy of the flagship HPX® product with low Kr factors, high cycling, and quality certifications that you’ve come to expect from Continental Disc Corporation. Optimum material thickness and manufacturing tooling design provide not only the full opening and accurate burst rating you expect, but also longer service life at higher operating-to-burst pressure ratios demanded by today’s process industries.

The CDC 3/4” SANITRX HPX® Rupture Disc is a semicircular scored reverse acting rupture disc designed specifically for applications in the pharmaceutical, food & beverage and biotech industries. This rupture disc is available to fit between standard sanitary ferrules. The 3/4” SANITRX HPX rupture disc is shipped in sanitary, environmentally friendly, non-toxic packaging.

The Continental Disc IntegrX-HPX™ rupture disc addresses the need within the biopharmaceutical industry to improve process performance, reliability, and safety. The pioneering and innovative IntegrX-HPX combines the unrivaled performance of the legendary HPX with ASME BPE compliant crevice-free inlet design, removing the need for integral seals. Traditional sanitary rupture disc designs limit access to the full spectrum of benefits delivered by HPX technology. The IntegrX-HPX is a semi-circular, scored, reverse-acting rupture disc, perfectly suited for cyclic process conditions from full vacuum to 90-95% of the stamped rating. Its welded design mitigates the impact of downstream piping loads on the rupture disc burst pressure and overall performance. Continental Disc incorporated an external tag, aiding installation and providing clearly visible identification in the field and easy access to marked data. IntegrX-HPX rupture disc offers a unique opportunity to boost efficiency, safety, and keep cost down by utilizing legendary HPX service life. The bold new design reduces maintenance, minimizes the chance of installation damage, and allows you to control the source and type of seal material without affecting rupture disc performance.

A semicircular scored, reverse acting rupture disc designed specifically for applications in the pharmaceutical, food & beverage and biotech industries that require pressures above SANITRX HPX. Ideal in a wide range of sanitary and hygienic applications, SANITRX HPX II rupture discs fit between industry-standard sanitary ferrules, NA-CONNECT® flanges, or SANITRX fittings, are in compliance with the essential criteria of the ASME BPE standards of cleanability, traceability and sterilization, and are shipped in sanitary, environmentally friendly, nontoxic packaging.

Get consistently accurate rupture disc installation with the HPX-PT pre-torqued holder. Prior to installation, you’ll install and fit the disc in your workshop. Then all you need to do is complete the assembly between the flanges in the process system relief stream. The HPX-PT pre-torqued holder incorporates high-strength steel socket-head cap screws for accurate loading and sealing of the rupture disc.

Secure your vessel and piping connections with the highly durable MBC Multiple-Bolt Sanitary Closure – trusted by pharmaceutical, biotech, food, beverage and fine chemical industries worldwide. The MBC features a two-piece cast stainless steel body, secured with four stainless steel bolts. This sturdy clamp yields the ultimate in connection integrity, providing a dependable, sure hold for system fittings and components. The MBC is designed to work seamlessly with the SANITRX rupture disc family.

Where process temperatures climb to levels your rupture disc or its lining material are unable to withstand, you need a CDC heat shield. The shield functions as a barrier, reducing your rupture disc’s exposure to high temperatures. It restricts the continuous flow of high-temperature gases or vapors, allowing the piping between the shield and rupture disc to act as a heat sink.

Protect piping, rupture discs and safety relief valves from rain, insects, birds and other unwanted foreign material with ENVIRO GUARD pipe end covers. Fabricated from a tough PTFE-impregnated fiberglass material, ENVIRO GUARD pipe end covers easily endure harsh environments and temperatures up to 500°F (260°C).

Use a double-disc assembly to simplify your piping arrangements, eliminate back pressure, detect leaks or create an actuated rapid-opening system. Three holder components (inlet, mid-flange and outlet piece) and two rupture discs make up the double-disc assembly. The first rupture disc fits between the inlet and the mid-flange, and the second goes between the mid-flange and outlet.

When used with our non-fragmenting MICRO X or Composite Flat Seat (FS) rupture discs, the UNISERT Assembly creates an effective seal every time. How? They were made for each other. The UNISERT is a flat seat rupture disc holder designed with superior sealing capabilities and easy installation. For use with any burst or pressure rating of the MICRO X or Composite Flat Seat rupture disc.

Keep your rupture disc clean, accurate and operational with the CLEAN-SWEEP Assembly. Designed for viscous media processes, the CLEAN-SWEEP Assembly significantly reduces dead space in pipe-tee rupture disc assemblies, eliminating product buildup and preventing interference or excessive overpressure. This holder is an ideal replacement for rupture disc assemblies installed off the leg of a pipe tee where product buildup could affect the proper operation of the rupture disc. With the CLEAN-SWEEP Assembly installed, the rupture disc mounts directly adjacent to the process flow.

Where product purity and corrosion resistance are critical, use our Sanitary Rupture Disc Holder Assembly. Quick-release and easy to change, this fitting assembly is trusted in dairy, pharmaceutical, food processing, canning, cosmetic and chemical industries.
