Flame Arrester

Flame arresters are one of the main accessories of pipeline equipment for flammable and explosive media. Their working principle is based on the principle that flames extinguish due to heat loss when passing through narrow pores of thermal conductors. When the flame passes through the small channels of the flame retardant element, the heat loss gradually increases, resulting in a decrease in combustion temperature and flame propagation speed. When the channel size decreases to a certain value, the heat loss of the pipe wall is greater than the reaction heat, and the flame cannot continue to propagate and is extinguished. The flame retardant layer structure of the flame arrester produced by Shanghai Meiyan Yipump Valve comes in various forms, including gravel type, metal wire mesh type, or corrugated type. Widely used between high-temperature equipment that is prone to fire and explosion, pipelines that transport flammable liquids, and storage containers and pipelines for flammable gases and liquids, as well as the venting ends of equipment.
