The air permeability of the flame retardant corrugated plate of the breathable cap should be checked frequently to ensure good flame retardant and air permeability properties. When maintaining, unscrew the upper cover of the breathable cap and loosen the screws securing the fire-resistant core. Remove the fire-resistant core and check whether the fire-resistant core is blocked, deformed or rusted. be cleaned or replaced immediately and checked twice a month.
There are some differences between the two, but they are both safety features.
The flame arrester is generally installed in the pipeline carrying combustible gas, or on the ventilated tank. It is a device that prevents the propagation of the flame (deflagration or detonation). It consists of a flame-arresting core, a flame-arresting shell and accessories.
The flame retardant vent cap is a safety device used to preventthe hydrogen flame to propagate outwards. It is made of a solid material (fireproof element) with many small channels or spaces that can allow gas to pass through. The gap or channel of the flame retardant element should be as small as possible, so that when the flame enters the flame arrester, the flame retardant element is divided into several small flame streams due to heat transfer ( the gas is cooled). ) and the wall effect, the flame flow is extinguished.
