Inline Deflagration Flame Arrester approved to EN ISO 16852

Inline Deflagration Flame Arrester approved to EN ISO 16852

Deflagration = Explosion propagating at subsonic velocity

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

Inline Deflagration : Explanation

Deflagration = Explosion propagating at subsonic velocity

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

Ignited explosive gas mixture will propagate through the pipe in direction to e.g. storage tank. With pipe length flame speed increases. Up to a certain pipe length / pipe inside diameter ratio, the flame propagates at subsonic speed. Inline flame arrester approved for deflagration stops flame propagation at subsonic speed.

Inline deflagration flame arresters has a lower pressure drop than detonation flame arresters.

However, consider when installing inline deflagration flame arrester that the distance from ignition source to inline deflagration flame arrester is limited.

Inline Deflagration Flame Arrester: Short Time Burning

Inline deflagration 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 Deflagration Flame Arrester: Endurance Burning

Stabilized burning for unlimited time.
