How to Size Natural Gas Pipe. 2539. The regulations of this chapter shall govern the installation of fuel gas piping in or in connection with a building, structure or within the property lines of premises up to 5 pounds-force per square inch (psi) (34 kPa), other than service pipe. Fuel gas branch lines under 2, over two, or no pipe size restriction on branch lines with brazing torch station and liquid flashback arrester componentsProtective 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.
