Product Details
Explosion proof pipeline flame arrester QGZW
overview
The series of explosion-proof pipeline flame arresters is a new type of combustible gas pipeline flame arrester, which is an updated and upgraded product.
The flame arrester has been jointly tested by the University of Science and Technology of China and the Tianjin Fire Science Research Institute of the Ministry of Public Security, and its performance fully complies with the provisions of GB13347-92 "Fire Arrest Performance and Test Methods for Flame Arresters in Petroleum Gas Pipelines". The structure of the flame arrester is reasonable, and the flame retardant layer is made of stainless steel material, which is corrosion-resistant and easy to clean. The shell is made of various materials such as stainless steel and carbon steel, which can meet the needs of different process pipelines.
Performance and characteristics
The flame arrester has a reasonable structure, light weight, corrosion resistance, and qualified explosion resistance performance. It has been tested for 13 consecutive subsonic flame tests and has been able to block fire every time.
Easy to maintain and install. The fire resistance performance is qualified, and there is no tempering phenomenon after 1 hour of fire resistance test.
The flame arrester core is made of stainless steel material, which is corrosion-resistant and easy to clean. The shell water pressure test is qualified.
scope of application
This flame arrester is suitable for pipelines, Class A with a flash point below 28 ℃, oil products, hydrogen oxygen liquefaction products, and kerosene, diesel, methyl benzene crude oil with a flash point below 60 ℃, pipelines transporting flammable gases, torch series, oil and gas recovery systems, heating furnace fuel gas pipeline networks, gas purification and purification systems, gas analysis systems, and coal mine gas emission systems.
