They prevent flash back against deflagrations in a pipe line. Therefore it is usually recommended that the flame arrestor be located as close to the potential source of ignition as possible. The maximum distance from the potential source of ignition will always be defined for any in-line deflagration flame arrestor and will be typically within 20 x the nominal bore of the pipe in which the arrestor is installed. If compliance with this constraint is not possible then it will be necessary to install a detonation flame arrestor which will withstand the more severe conditions that could occur.

Detonation Flame Arrestors are designed to be installed in a pipeline where there is a significant distance between the arrestor and the potential source of ignition, or where the pipe line contains multiple bends, elbows and other changes of direction, all of which create turbulence and increase flame front speed. In-line detonation Flame Arrestor offer protection against high flame velocities, where the velocity is supersonic and is accompanied by a shock wave. Detonation arrestors must be especially applied when long pipes are connected between arrestor and ignition source.
