[0002] Flame arresters are safety devices used to prevent the spread of flames of flammable gases and flammable liquid vapors. They are generally installed in pipelines that transport flammable gases or on ventilated tanks to prevent the spread of flames (deflagration or detonation). They are composed of a flame arrester core, a flame arrester shell, and accessories. Explosion-proof flame arresters undergo strict testing before leaving the factory, and some important performance indicators are tested.
