What is the function of a flame arrester in a bulk oxygen storage system?

The function of a flame arrester in a bulk oxygen storage system is to prevent a flame or spark from traveling upstream through the piping system and reaching the oxygen source, where it could cause a catastrophic fire or explosion. Oxygen, while not itself flammable, vigorously supports combustion, meaning it greatly accelerates the burning of flammable materials. A flame arrester is a safety device that allows gas to flow through it but stops a flame. It typically consists of a porous material, such as a crimped metal ribbon or a sintered metal matrix, which absorbs heat from the flame and cools it below the ignition temperature of the surrounding gases. This prevents the flame from propagating beyond the arrester. In a bulk oxygen system, a flame arrester is strategically placed in the piping to protect the oxygen source from potential ignition sources downstream, such as welding equipment or faulty connections. Properly maintained flame arresters are critical safety components in any system involving flammable gases or oxidizers.
