End of Line Deflagration Flame Arrester

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.

End of Line Deflagration Flame Arrester

End of Line Deflagration Flame Arrester ( flame arresting ) allow free venting in combination with flame protection for vertical vent applications. They prevent flame propagation by absorbing and dissipating heat using spiral wound crimped ribbon stainless steel flame cells.

End of Line Deflagration Flame Arrester is used in applications such as petroleum storage tank vents.The classic application is in preventing fire in the atmosphere from entering an enclosure. Flame arresters began to be installed on vents on oilfield storage tanks for a long time. They keep the tanks from exploding when gas flowing from the vents is struck by lightning.

Conversely, someEnd of Line Deflagration Flame Arrester prevent fire in an enclosure from igniting an explosive atmosphere such as in a refinery. For instance, flame arresters may be installed in furnace air inlets and exhaust stacks.

Product Features

End of Line flame arrester is designed to be installed at the end connection of a tank vent line. The flame arrester provides a protection barrier that deters a flame generated from a source outside of the tank from flashing through the vent into the vapor space of the tank.

Stopping the spread of an open fire

Limiting the spread of an already occurred explosion

Preventing potentially explosive mixtures from igniting

Confining fire within a controlled location

Stopping the propagation of a flame traveling at subsonic velocities

Product application

Fuel storage tank vents

Fuel gas pipelines

Safety storage cabinets for paint, aerosol cans, and other flammable mixtures

The exhaust system of internal combustion engines

The air intake of marine inboard engines

Davy lamps in coal mining

Overproof rum and other flammable liquors.
