Flame Arrestor
Flame Arresters - Groth Corporation (Made in USA)

A flame arrester (alternative spelling flame arrestor) is a passive device designed to prevents the passage of flame without impeding the flow of gas in and out of a vessel or pipe. They can may be used to prevent flames from within a vessel escaping but also prevent flames from ingressing a potentially explosive environment.

Flame arresters can be grouped into 2 categories. Deflagration flame Arrestors and Detonation Flame Arrestors. To put it simply, Deflagration Fame Arrestors are designed to handle to handle subsonic combustion where the later, Detonation Flame Arrestors, are equipped to handle supersonic reactions and the corresponding shock wave produced when a material detonates.

Flame arresters are a relative simple in concept with no moving parts. They are constructed of a sturdy body and one or more flame arrester elements which can vary in design depending on the application, zoning, material and flow requirements. The flame arrester element(s) extinguishes the flame by directing it through many narrow passages to cool it to the point that a flame can no longer be sustained.
