Principles of Operation

The Elmac Technologies® UEA Series of In-line Unstable Detonation Flame Arresters is designed to prevent the propagation of gas or vapour explosions in pipelines under the most severe conditions of unstable detonation, stable detonation and deflagration. This type of flame arrester is specified for use in pipeline systems where the distance between the source of ignition and the flame arrester is significant and/or where detonations are possible.

The combination of our unique patented High Energy Dissipation System (HEDS™) and E-Flow™ technology attenuates the shock wave and extinguishes the flame, thus mitigating the effects of an explosion by preventing its propagation. The UEA Series of In-line Unstable Detonation Flame Arresters uses an optimised crimped ribbon element which allows gas or vapour to pass with minimal pressure loss. Designed to withstand the extreme pressures that travel at supersonic velocities in a detonation event, the UEA Series has been developed in line with Elmac’s long-term strategy on the provision of protection for both plant and personnel strategy of providing protection whilst maintaining market leading flow vs pressure drop performance.

Explosion Groups

Elmac’s UEA Series of In-line Unstable Detonation Flame Arresters is ATEX approved for gases in Explosion Groups IIA & IIA1.

Standards Compliance

Elmac’s UEA Series of In-line Unstable Detonation Flame Arresters has been type-tested to EN ISO 16852 and approved according to ATEX Directive 2014/34/EU.
