Explosion-proof air vent air vent is used to prevent \ gas, liquid flame safety device to prevent the spread and caused tempering. Usually mounted on the exhaust gas transport or storage tanks and pipelines. Role breathable cap is to prevent external flame fleeing there gas equipment, pipeline or prevent the spread of flame between devices, pipes. Arrester design and manufacture of application of the principles of flame through the narrow pore heat conductor, since heat loss and extinguished. Fire retardant breathable cap main features: on SCZ50-A-proof air vent and the introduction of an integrated Britain, Germany and other company's advanced technology, combined with advanced processing equipment and improve the detection equipment, the production of explosion-proof corrugated flame arrester, compact structure high reliability, fire retardant core explosion, corrosion, strong fire resistance, ease of cleaning, etc., especially suitable for hydrogen, nitrogen, oxygen, liquefied petroleum gas and other special media. Arrester by the Chinese Ministry of Public Security in Tianjin Institute of Science and Technology, University of Science and fire joint testing, its performance in full compliance with GB13347-92 "oil and gas pipeline flame arrester and test methods" requirement. Technical Data: Housing Material: carbon steel, aluminum, stainless steel flame arrester core: stainless steel explosion-proof fire retardant corrugated board. Ring material: Teflon. Working temperature: ≤480 ℃. Explosion levels: BS 5501; IIA, IIB, IIC. Scope: storage flash point lower than 60 ℃ of petrochemical products.
