    Pipe Sizing Chart

    Fuel gas branch lines under 2, over two, or no pipe size restriction on branch lines with brazing torch station and liquid flashback arrester components

    Protective equipment, including a flashback arrester, is required in fuel gas and oxygen piping systems to prevent a reverse flow of oxygen from flowing back up the fuel gas line, or a reverse flow of fuel gas from flowing back up the oxygen line, also to prevent excessive pressure build-up in the system and stop a flashback from reaching the supply source. Piping systems shown comply to National Fire Protection Association Bulletin #51. Copies can be obtained by writing
