G2 Technology for Premium Rupture Disc Manufacturing

Fike's Patented G2 Manufacturing

While bulging the metal, an engineered reversal point is implemented, which allows for precise control of the disc’s burst pressure. This technique allows us to “control the reversal,” creating an ultra-reliable disc that’s proven to withstand in excess of 100,000 cycles.

Scoring and coining methods used to create the disc’s opening feature may cause microscopic mechanical damage, resulting in loss of burst tolerance control. G2’s laser ablating and milling technologies remove material rather than compress it, greatly enhancing performance and reliability.

Most configurations of G2 rupture disc sizes, burst pressures and materials have been pre-engineered and pre-calculated. Therefore, a rupture disc with any combination of variables may be manufactured with maximum reliability and the shortest lead times in the industry.

What Does G2 Mean for You?

Superior Reliability

Features our highest operating ratio of 95 percent, allowing production facilities to run at full capacity without worry of altering burst pressure.

Extraction Scoring

Opening feature is laser-ablated or milled, not scored, providing an ultra-reliable line of weakness not found in work-hardened scoring methods.

High Life Cycle

Superior cycling performance for processes running from full vacuum to 95 percent of burst pressure. Extremely high cycle life profiles available for less demanding cyclic conditions.

Backpressure/Vacuum Resistant

Concave surface faces the process side and can withstand full vacuum without added support; also ideal for in situ testing of pressure relief valves.
