Direct-Mount Composite Rupture Discs

When it comes to protecting large-scale pressurized systems, finding a solution that balances high performance with installation simplicity is a common challenge for plant managers. CDC-DM™ and CDCV-DM™ rupture discs from Continental Disc Corporation offer a direct mounted, “holder-less” solution, specifically designed for instantaneous, full-opening pressure relief. These rupture discs eliminate the need for a separate holder and mount directly between standard flanges, in systems ranging from 14” to 36” in size. This reduces both the footprint and the complexity of your pressure relief setup while maintaining an impressive 80% operating-to-burst pressure ratio.

The versatility of this series makes it a go-to choice for a variety of demanding industrial environments, particularly within chemical processing and petrochemical applications. The CDC-DM is ideal for systems not subject to vacuum, while the CDCV-DM is engineered to withstand full vacuum conditions without compromising safety. Both models feature a unique seven-hole pattern at the apex of the dome, which allows for the use of thicker, more durable materials while ensuring non-fragmenting characteristics when paired with a fluoropolymer seal. Available in a wide range of corrosion-resistant materials (including 316 SS, Alloy C276, and Nickel) these discs provide robust protection for both liquid and gas/vapor applications.
