flame arrester

Flame arresters and detonation arresters are passive mechanical devices that are mounted to threaded or flanged connections on a tank or in a process piping system. in normal operation, vapors in the pipe are directed through the arrester.
Flame arrestors are installed below pipe vents to prevent a flame front from moving backwards into the pipes and vessels below the vent tip (this backward movement can occur when the mixture is in the flammable range but the velocity at the open end exceeds the flame propagation velocity). if the flame does travel backwards it can gain velocity, eventually reaching supersonic or u2026
