International safety standards identify two main types of flame arrester: detonation arresters and deflagration arresters. Deflagration arresters include in-line and end-of-line designs, each built for specific combustion risks and conditions. A flame arrester lets gases pass while stopping flames from spreading, helping prevent explosions. Compliance with EN lS0 16852:2016 ensures these devices meet global safety expectations. Choosing the right type protects equipment and people in hazardous environments.
End-of-line flame arresters sit at the end of pipes or vents, usually where gases exit into the open air. Their main job is to stop flames from entering storage tanks or pipelines from outside sources, such as lightning or sparks in the atmosphere. These devices protect tanks, valves, and vent systems by blocking external ignition and preventing explosions.
End-of-line flame arresters remove heat from a flame as it passes through narrow metal passages. This cooling action drops the temperature below the ignition point, stopping the flame from spreading.
In-line deflagration flame arresters are installed inside pipes or ducts. They stop flames that start within the system and prevent them from moving downstream. Deflagration means a flame travels through a gas mixture at a speed slower than sound. This type of flame is common in industrial settings.
In-line detonation flame arresters are built for the most severe conditions.Detonation is a type of explosion where the flame front moves faster than the speed of sound, creating a shock wave. This event causes much higher pressure and temperature than deflagration.
| Type | Main Function | Typical Applications | Distinguishing Features |
| End-of-Line Flame Arresters | Stops external flames from entering systems | Storage tanks, vents, valves | Easy installation, high flow resistance |
| In-Line Deflagration Flame Arresters | Stops flames traveling inside at subsonic speed | Piping, process lines, reactors | Large surface area, low-pressure applications |
| In-Line Detonation Flame Arresters | Stops supersonic flames and shock waves | Vapor recovery, storage, combustion | Heavy-duty, withstands high pressure/temperature |
The effectiveness of any flame arrester depends on proper selection installation, and regular maintenance. Always match the arrester type to the specific risk and system design.
