Flame arrester refers to the safety protection equipment that prevents the flame from spreading and spreading in the pipeline. Generally installed in the pipeline conveying combustible gas, or on the ventilated tank, to prevent the transmission of flame (deflagration or detonation) through the device, consisting of a fire retardant core, flame arrester shell and accessories. Flame arresters are also commonly used in pipelines carrying flammable gases.
