A flame arrester is a device fitted to the opening of an enclosure or to the connecting pipe work in a system of enclosures and which permits gases or vapours to flow under normal operating conditions but prevents the transmission of a flame should an ignition take place.
A Flame arrestor is a safety device whose principal purpose is to prevent a flame entering or leaving a pipe or vessel or to prevent it travelling further down a pipe. In many cases it is used in conjunction with the components to create a safety system. Failure to stop a flame can result in catastrophic damage to equipment, loss of production, injury to people and even loss of life and potentially large litigation costs.
The dimensions should be at least 4 m circumference, 4 m length and a material wall thickness of 0.05 mm.
