These pressure-relief devices simplify direct-mounting
The CDC-CM™ and CDCV-DM™ composite rupture discs (photo) are advanced, holder-less differential pressure-relief devices are engineered to protect pressurized systems, equipment and vessels in critical applications in chemical processing, petrochemicals, oil-and-gas and energy production industries from potentially damaging overpressure conditions. Designed to provide instantaneous, full-opening pressure relief in both liquid and gas-vapor environments, the CDC-DM and CDCV-DM rupture discs provide reliability, corrosion resistance and high performance across a broad range of operating conditions. The new designs incorporate CDC’s proven composite rupture-disc technology with a simplified direct-mount configuration, reducing installation time while maintaining high safety standards. CDC-DM and CDCV-DM direct-mount rupture discs feature a preformed metallic top section with a unique seven-hole apex pattern that ensures non-fragmenting performance when paired with fluoropolymer seals. This construction allows for the use of more durable materials while still achieving an 80% operating-to-burst pressure ratio, one of the highest available in composite discs. Sizes available are 14–36 in. — Continental Disc Corp., Liberty, Mo.
