A Flame arrestor arrest the flame from entering through an opening. It's a device which stops fuel combustion. It act as a flame extinguisher. They are commonly installed on atmospheric-pressure storage tanks, process vessels, and transportation container. It is also known as deflagration arrester, or flame trap.
These arresters are bi-directional, capable of stopping a flame approaching from either long direction or complex piping runs in a manifolded tank systems.
Flame Arrestor is a passive device that allows the gas to flow through the piping system. If the mixture is ignited and the flame begins to travel back through the piping, the arrester will prohibit the flame from moving back to the gas source. The cleaning of flame arrestor takes place using a carb cleaner spray. It is made up of wound, corrugated metal strips.
