Pipeline flame arrester, also known as fire extinguisher, is a device that prevents external flames from entering equipment or pipelines containing flammable and explosive gases, or prevents flames from spreading between equipment and pipelines. It is a safety device used to prevent the spread of hydrogen flames outward, composed of a solid material (flame retardant element) with many small channels or gaps that can pass through the gas. Pipeline explosion-proof flame arrester is a safety device used to prevent the spread of flames of flammable gases and liquids and to prevent explosions caused by backfire. Usually installed on pipelines that transport or discharge flammable and explosive gases. Such as torches, heating and combustion systems, petroleum gas recovery systems, or other flammable gas systems.
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.
The flame arrester has a reasonable structure, light weight, corrosion resistance, and qualified flame retardant performance. It has been tested for 13 consecutive subsonic flame tests and can be flame retardant each 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.

In order to ensure the safe use of flame arresters, they should be regularly inspected and maintained.
1. The flame arrester should be inspected every six months to check whether the flame arrester core is blocked, deformed, corroded, etc.
2. The blocked fire-resistant layer core should be cleaned thoroughly to ensure that each hole on the core is unobstructed, and any deformed or corroded fire-resistant layer should be replaced.
3. When reinstalling the fire-resistant layer core, it should be ensured that the joint surface is tight and there is no air leakage.
