Pipeline Explosion-Proof Flame Arrester
A pipeline explosion-proof flame arrester is a safety device used to prevent the spread of flames from flammable gases or liquids and to avert explosions caused by backfire. It is typically installed on pipelines that transport or discharge flammable and explosive gases, such as flare stacks, heating combustion systems, petroleum gas recovery systems, or other flammable gas systems. Based on the operating conditions, it can be divided into two types: deflagration arrester and detonation arrester.
Structural Features
Deflagration Arrester
Utilizes the wall effect of corrugated plates to reduce the generation of free radicals, preventing the flame from sustaining propagation and thereby halting its spread.
Excellent deflagration arrestment performance, capable of withstanding 13 consecutive subsonic flame arrest tests. Particularly suitable for installation at the pipe end of discharge lines.
Operating temperature: -196°C to 480°C; Working pressure: PN20 to PN250.
No check valve required; No specific installation direction.
Detonation Arrester
Features a bi-directional corrugated plate design, providing a stronger wall effect to reduce free radical generation and prevent sustained flame propagation, thereby stopping flame spread.
Excellent detonation arrestment performance, capable of withstanding 5 consecutive detonation tests and 10 deflagration tests. Suitable for flame arrestment in hydrogen pipeline systems.
Operating temperature: -196°C to 600°C; Working pressure: PN20 to PN420.
No check valve required; No specific installation direction.
