A flame arrester is an important safety device designed to prevent the occurrence and spread of fires and explosions; it prevents flames from spreading through pipelines, thus avoiding catastrophic chain reactions. It serves as a crucial physical barrier in industrial safety. It is like an extremely calm and efficient \"flame security guard\" stationed at the entrance to pipes or equipment; its core skill is: \"Gases and energy can pass through, but flames will never make it past here!\" ”. Flame arresters can be widely used in preventing and controlling gas fires and explosions in industries such as petroleum, petrochemicals, chemicals, pharmaceuticals, and steelmaking, including systems with interconnected gas storage tanks, various VOCs treatment systems, combustion equipment such as heating furnaces, flares, and the ends of vent pipes. By conducting in-depth research on the propagation patterns of detonation waves in expanding chambers, the Sinopec Safety Engineering Research Institute has innovatively proposed a detonation-induced mitigation technique based on \"guided waves + cell destruction\". This technology significantly improves flame retardancy while also optimizing flow performance ； The largest and most capable comprehensive performance testing platform for flame arresters in China has been established, offering complete testing capabilities covering flame arrestation performance, burn resistance, and flow pressure drop characteristics; this provides important theoretical support for the design of high-performance flame arresters. Based on the technology and testing platform of Anhui Institute of Engineering, a series of flame arrestors suitable for various operating conditions have been successfully developed, including those for low-pressure drop pipeline steady-state detonation, unsteady-state detonation, deflagration, burn resistance, and large-size applications. These products effectively address the long-standing industry challenge related to the lack of high-performance flame arrestors. This series of products boasts advantages such as strong performance, high safety margins, a wide range of specifications, and low prices (only 30%-50% of those of imported products). It is one of the fire suppression solutions in China that currently has the most comprehensive qualifications and can be applied in the widest range of scenarios.
