The function of pipeline flame arrester is to prevent the external flame from entering the equipment and pipeline containing flammable and explosive gas or preventing the flame from spreading between the equipment and pipelines.
Pipe flame arrester is designed and manufactured according to the principle that the flame goes out due to heat loss when it passes through the narrow pores of the thermal conductor. The structure of fire retardant layer of flame arrester has gravel type, wire mesh type or corrugated type. It is suitable for flammable gas pipeline, such as gasoline, kerosene, light diesel oil, benzene, toluene, crude oil and other oil products storage or flare system, gas purification and communication system, gas analysis system, coal mine gas drainage system, heating furnace fuel gas pipeline network, and also can be used for acetylene, oxygen, nitrogen, gas pipeline supplies. The valve can be used together with the breathing valve or used alone. This kind of valve should be installed horizontally or vertically according to the working condition in the pipeline.
