Specialized Rupture Discs

Our explosion vent panels provide instantaneous overpressure protection for nearly any type of pressurized dry-bulk handling and storage equipment. The vent panels are designed to allow a full and immediate opening to minimize structural or mechanical damage by expanded gases from the combustion of dust, gases or mists inside equipment, rooms, buildings or other enclosures.

Protect equipment, personnel and the environment with the threaded, single-use WMP Welded Muffled Plug rupture disc assembly. The WMP is ideal for applications that discharge to the atmosphere at the rupture disc. The WMP is a solid-metal, tension-acting rupture disc that screws directly into a threaded port, providing precise overpressure protection with minimal installation time.

Replace shear pins and other moving devices with our Well Activation and Safety Protection rupture discs to save valuable time and labor on the drill site. Designed to release pressure to activate tools in the hole or to protect downhole drill components from overpressure failure, our Well Activation and Safety Protection Rupture Discs use rupture disc technology to achieve high accuracy and reliability. These rupture discs are offered in two burst-direction configurations, Type A and Type I.

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.
