A detonation 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 arresters are always designed to deal with unstable detonations. In the context of the Pressure Equipment Directive (PED), Motherwell detonation arresters are classified as a piping assembly.
