Flame Arrestor Function: Flame arrestors are designed to prevent the propagation of flames and sparks from entering or escaping a pipeline or vessel. In gas systems, they are particularly essential to arrest flames that could reach areas with a high concentration of fuel, thereby preventing accidents and explosions.
Backfire Prevention: In gas pressure reducing systems, backfires can occur due to various factors, such as sudden pressure changes, ignition sources, or equipment failures. A backfire is a dangerous event where a flame travels back into the pipeline or equipment. Flame arrestors are positioned in the gas line to halt the progress of any backfire and prevent it from reaching areas where there is a dense concentration of fuel, thereby averting accidents and explosions.
