Explosion Proof Flame Arrester

The explosion-proof flame arrester (also called a deflagration arrester) functions by absorbing the heat from a flame front traveling at subsonic velocities, thus dropping the burning gas/air mixture below its auto-ignition temperature: consequently, the flame cannot survive. The heat is absorbed through channels (passages) designed into an element.

For flame arresters used as a safety device, the mesh must be protected from damage due to being dropped or struck by another object, and the mesh must be capable of rigidly retaining its shape during the propagation of a flame front. Any shifting of the individual wires that make up the mesh can create an opening large enough to allow the flame to penetrate and spread beyond the barrier.

On a fuel storage vent, flame arresters also serve a secondary purpose of allowing air pressure to equalize inside the tank when fuel is added or removed, while also preventing insects from flying or crawling into the vent piping and fouling the fuel in the tanks and pipes.

* Prevent unconfined deflagration.
* Selection of explosion group: IIA,IIB1,IIB2,IIB3,IIB,IIC
* Low pressure drop and excellent flow capacity
* Maintenance friendly and cost effective.
* Weather hood provides pretection against environment impact
* Operation temperature up tp 60℃ and operating pressure up to 0.11MPa. it can be designed according to users' requirements.
* Default flange connection for ASME B16.5 150Lb RF. It can be designed according to users' requirements.
