Flame Arresters (Detonation)

Flame arresters are passive devices which are fitted within or at the end of a pipeline to prevent the onward travel of a flame path. They are used to contain an incident and protect high-value equipment such as vapour recovery units. An arrester prevents the propagation of flame from the exposed side of the unit to the protected side using a metal matrix called an element. An element comprises a bundle of narrow metal channels which remove heat from the flame and starve it of oxygen as it is attempts to pass through it. The diameter and length of the channels within the element will vary significantly, depending on the flammability of the gas (gas group) the arrester is designed for used with.

Detonation flame arresters are required where a flame path has the potential to travel at supersonic velocities. This is dictated by the position of the arrester, specifically the length of the pipe-run between the arrester and the potential source of ignition. The physical difference between a deflagration and detonation arrester is that the latter is designed to withstand the shock and extreme pressures that a supersonic flame path can generate – generally resulting in a larger, heavier unit.
