In-Line Detonation Flame Arrester

Motherwell Tank Protection in line unstable detonation flame arresters are designed to prevent propagation of detonations in gas or vapour mixtures. Detonation flame arresters are specifically designed for pipelines with a significant distance between the ignition source and the arrester, or for use where the pipe is rough, bent, obstructed or has section changes. CE-IB unstable detonation flame arresters are supplied as complete units ready for direct installation into piping systems. 

A detonation flame arrester uses a crimped ribbon element with small apertures which allows gas or vapour to pass. The elements are designed so that they both attenuate the detonation shock wave and extinguish the flame. Motherwell detonation flame arresters are always designed to deal with unstable detonations. In the context of the Pressure Equipment Directive (PED), Motherwell detonation flame arresters are classified as a piping assembly.
