Detonation Flame Arrester

Detonation Flame Arrester

The Detonation Flame Arrester represents the best value in flame arrester protection. They prevent flame propagation by absorbing and dissipating heat using spiral wound crimped ribbon flame cells. These cells allow maximum flow with maximum protection. They provide protection against flame propagation in piping systems that are manifolded or have long run-up distances.

A patented element assembly is used to dampen the high velocities and pressures associated with deflagrations and detonations while quenching the flame front. This unique design has the ability to provide larger flame channels which requires less frequent maintenance and greater ease in cleaning when service is required, translating to less down time. the patented element offers maximum flow to pressure drop characteristics enhancing the value of the product in any system.

They are typically used for extended pipe length or multiple pipe bend configurations to stop high pressures and flame velocities associated with detonations and overdriven detonations. In addition, it stops confined and unconfined, low and high pressure deflagrations. All units are bi-directional and are proven to stop an ignited flammable vapor mixture approaching from either direction that can be traveling at subsonic or supersonic velocities.

Designed with flanged connections, this Arrester provides the option of the removal of the flame cell element for easy cleaning and replacement without disconnecting of the pipe connection. Standard housing construction is carbon steel and stainless steel. The element is available in 304 S.S and 316 S.S. Special material end protective coatings are available on request.
