The role of a flame arrester is to prevent external flame channeling into flammable and explosive gases in the equipment, pipes or prevent flame spread between equipment, pipelines. Flame arrester is also called flame filter, flame trap and fire arrester. Usually installed in the delivery or discharge of flammable and explosive gas storage tanks and pipelines. Such as torches, heating combustion systems, petroleum gas recovery systems or other flammable gas systems. Stored light below 60 DEG C for petrochemical products. Can be matched with the use of breathing valve, but also can be used alone. Internal floating roof tank ventilation pipe.
