WebRexarc’s flashback arresters are designed for use in facilities, where acetylene gas is used for oxy-welding and cutting processes as well as where any fuel gas is combined with an oxidizer at point of use. The flashback arresters feature the following major components: Inlet Pipe with Check Valve. Flow Diverter. Dry flashback arrestors typically use a combination of safety elements to stop a flashback or reverse flow of gas. This type is typically found in cutting and welding applications all over the world. They work equally effectively in all orientations, and need very little maintenance. The simplest flashback arrestor consists of a metallic tube filled with iron wool, which cools the flame below the ignition temperature.
