Flame Arrester approved to EN ISO 16852 for Atmospheric Explosion (Deflagration)
Deflagration = Explosion propagating at subsonic velocity
End of line deflagration flame arrester installed at end of vent pipe prevents light-back at deflagration of potentially explosive vapour-air or gas-air mixtures from outside (atmospheric conditions) to the protected side (e. g. storage tank).
END OF LINE FLAME ARRESTER / DEFINITION
End of Line Flame Arrester : Explanation
End of line flame arrester: Flame arrester that is fitted with one pipe connection only.
Deflagration = Explosion propagating at subsonic velocity
End of line deflagration flame arrester is fitted at the end of vent line. Even at a small pressure difference between storage tank and atmosphere, gas, steam or aerosol escapes through the vent. If this gas, vapor or aerosol is ignited, then flame will propagate through the vent line into storage system.
End-of-line deflagration flame arresters stops flame propagation at atmospheric explosion before flame enters into the storage tank.
