Inline Detonation Flame Arrester: Concentric

Inline Detonation Flame Arrester approved to EN ISO 16852

Deflagration = Explosion propagating at subsonic velocity

Detonation = Explosion propagating at supersonic velocity and characterized by a shock wave

Inline detonation flame arrester prevents a flame propagation to the protected side in case of deflagration and detonation of explosive vapor-air or gas-air mixtures.

Inline Detonation Flame Arrester : Explanation

Deflagration = Explosion propagating at subsonic velocity

Detonation = Explosion propagating at supersonic velocity and characterized by a shock wave

Inline detonation flame arresters are fitted with two pipe connections, one on each side of the flame arrester. They are designed to prevent transmission of detonation (explosion propagating at supersonic velocity).

Ignited explosive gas mixture will propagate through the pipe in direction to e.g. storage tank. With pipe length the speed of flame will increase. Up to a certain pipe length / pipe inside diameter ratio, the flame propagate changes from subsonic speed (Deflagration) to supersonic speed (Detonation).

The installation position of the inline detonation flame arrester is independent of the distance to the ignition source. Inline detonation flame arresters are also approved as inline deflagration flame arresters.

Inline Detonation Flame Arrester: Eccentric

Eccentric type inline detonation flame arresters in horizontal installation are preventing condensate accumulation inside of the arrester.

Inline Detonation Flame Arrester: Short Time Burning

Inline detonation flame arrester approved for stabilized burning for specified time. For detection of a stabilized flame a PT100 temperature sensor mounted on the unprotected side is necessary! When a stabilized flame is detected an action within 30 seconds has to be carried out which ensures a safe quenching of the flame. (E.g. stopping the gas flow)

Inline Detonation Flame Arrester: Endurance Burning

Inline detonation flame arrester approved for stabilized burning for unlimited time.

Inline Detonation Flame Arrester: Elbow Type (90°)

Inline detonation flame arrester as elbow type allow an easy access for cleaning the flame arrestor elements.
