INLINE DETONATION FLAME ARRESTER: ELBOW TYPE 90กใ
|
INLINE DETONATION FLAME ARRESTER: ELBOW TYPE 90กใ |
Inline Detonation Flame Arrester approved to EN ISO 16852 as Elbow Type (90°)
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
Inline Detonation Flame Arrester – Elbow Type (90°): 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. Inline detonation flame arresters are designed to prevent the transmission of a detonation (explosion propagate 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 Elbow type (90 °) design of inline detonation flame arrester saves a pipe bend compared to the concentric or eccentric design and allows easy access to the flame arrester element during maintenance.
