Rupture Disc a Pressure relief solution

Rupture disc is designed to provide a leak tight seal within a pipe or vessel until the internal pressure rises to a predetermined level. At that point, the disc bursts preventing damage to the equipment from overpressure.

ASME Section VIII, Division 1, Application Requirements

The ASME Code defines certain sizing and pressure rating criteria for various applications of rupture discs. In the case of primary relief or sole relieving device (shown in fig. 1), it must be sized to prevent the pressure in the vessel from rising more than 10% or 3 psi, whichever is greater, above the maximum allowable working pressure (MAWP) of the vessel. In addition, the rupture disc marked burst pressure shall not exceed the MAWP.

The ASME Code allows rupture disc devices to be used in multiple as a secondary device to other rupture disc devices or pressure relief valves (shown in fig. 2). In this case, the secondary device is sized to prevent the pressure in the vessel from rising more than 16% or 4 psi, whichever is greater, above the MAWP. The burst pressure of the secondary device may be marked at a pressure not exceeding 105% of the MAWP.

Fike’s G2 Technology

G2 is a patented, state-of-the-art technology used to manufacture rupture discs without hard-score tooling, producing no stress zones that can fatigue and offering premium performance. The result is a low pressure rupture disc solution featuring tight burst tolerances and extremely high operating ratios. In addition, the advanced automation significantly increases consistency and provides for fast, economical delivery time.

Fike’s premier discs, the Axius®, Axius® SCand ATLAS are products of G2 Technology
