Forward-Acting Rupture Discs

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.

A single, solid, phenolic resin-impregnated slab of graphite makes up the GRAFSERT rupture disc. This design makes the GRAFSERT a highly dependable, low-maintenance rupture disc, ideal for highly corrosive applications and remote installations. The GRAFSERT is single-direction disc capable of withstanding burst ratios up to 80% in static service.

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 features a flat seat design for superior metal-to-metal sealing. 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.
