End-of-Line Deflagration Flame Arresters

In a “stand-alone” tank system, each tank is effectively isolated from the other storage tanks. The most likely ignition sources are external to the tank, and the transmission of a flame among multiple tanks can usually occur only by the spread of an external fire. In such a “stand-alone” system, the flame arrester is typically mounted at the end of the tank vent pipe (End-of-Line Deflagration Flame Arrester).

Its intended function is to permit normal tank breathing, while preventing the “flash-back” of an unconfined deflagration (a flame front moving in an unrestricted space at speed less than the speed of sound) through the arrester and into the tank’s vapor space. The End-of-Line Deflagration Flame Arrester provides positive protection against an external flame source entering the tank.
