Axius reverse-acting rupture disc

Designed to be used in aggressive chemical and pharmaceutical applications, the Axius reverse-acting rupture disc is available in corrosion-resistant materials and has the tightest tolerances available. The rupture disc can also operate without fatigue from full vacuum up to a 95% operating ratio for over 50,000 cycles. Using Fike’s new G2 Technology, the Axius rupture disc was developed without using traditional tooling methods, such as coining or scoring. When tooling is used to create a score line it stresses the material where the tooling has been applied, thus creating an area for potential early fatigue and/or failure. This means more replacement discs for plants to purchase. Instead of a score line on the edge of the disc, the Axius has a “line of weakness” on the dome itself. Thus there are no stress zones that can fatigue and no tool marks or indentations on the process side of the rupture disc, making this the only 95% operating ratio disc with a completely smooth process surface. This enables the Axius to deliver higher operating ratios without chemical build-up so that plant managers can get more work out of their rupture disc and their production process.
