Flashback Arrestors

Flash Back Arresters are most commonly used in Oxy - Fuel welding and cutting. They are installed in a pipeline or at the end of the tapping point prior to the torch. They stop the flame from burning back upstream of the pipeline and causing damage or explosions. They are designed to allow free flow of gas through them but to take out the heat of the flame front so as to bring it below the ignition temperature of the burning gas mixture
