First, the pipeline flame arrester overview
The new combustible gas pipeline flame arrester is a new product that is updated. The performance is in full compliance with the provisions of GB13347-92 "Fire-resistance and test methods for fire-retardant of petroleum gas pipelines". The flame arrester has a reasonable structure, and the fire barrier layer is made of stainless steel, which is corrosion resistant and easy to clean. The shell is made of stainless steel, carbon steel and other materials to meet the needs of various process pipes.
Second, the performance and characteristics of pipeline flame arresters
The flame arrester has a reasonable structure, light weight, corrosion resistance and good anti-explosion performance. It can be fired every time for 13 times in a subsonic flame test. Easy to repair and easy to install. It has good resistance to burning and has no tempering for 1 hour. The flame arrester core is made of stainless steel and is corrosion resistant and easy to clean. The shell hydraulic pressure test passed.
Third, the scope of pipeline flame arresters
The flame arrester is suitable for pipelines, Class A with flash point below 28 °C, oil products, liquefaction of hydrogen and oxygen, kerosene, diesel oil, and stupid crude oil with flash point below 60 °C, and pipes for conveying flammable gases and torches. Series, oil and gas recovery system, tube network of heating furnace fuel gas, gas purification and communication system, gas analysis system, coal mine gas emission system.
