Standard for Installation of Fire Safety Devices based on Use and Occupancy Article 89

Piping of CO2 and Inert Gas fire extinguishing systems shall be installed pursuant to the following provisions:1.The piping shall be exclusive, and the diameter shall be determined according to flow calculation.2.Head drop between the lowest piping and highest piping shall be determined according to flow calculation and shall be less than 50m.In addition to the above regulations, piping of CO2 fire extinguishing sys-tems shall also comply with the following provisions:1.Seamless steel pipe conforming to CNS 4626 shall be used, where Sch80 pipe or higher shall be for high-pressure application and Sch40 pipe or higher for low-pressure application for the thickness or having equivalent or higher strength; and piping shall be galvanized or treated for corrosion prevention.2.When copper piping is employed, seamless copper or copper alloy pipes conforming to CNS 5127 specifications or those having equivalent or higher strength shall be used; where the high-pressure type shall endure at least 165kgf/cm2 or 16.5Mpa pressure and low-pressure type at least 37.5kgf/cm2 or 3.75Mpa pressure.3.Pressure endurance of piping connectors and valves shall be at least 165kgf/cm2 or 16.5Mpa for the high-pressure type and at least 37.5kgf/cm2 or 3.75Mpa for the low-pressure type, with proper anti-corrosion treatment provided.In addition to Item 1 provisions, piping of Inert Gas Fire Extinguishing sys-tems shall also comply with the following regulations:1.Sch80 seamless steel pipe conforming to CNS 4626 with equivalent or higher thickness and strength shall be used. However, for secondary side piping provided with pressure regulating devices, steel pipe durable to at least the maximum regulated pressure at 40°C may be used, with the provision of galvanization or corrosion prevention treatment.2.When copper piping is employed, seamless copper or copper alloy pipes conforming to CNS 5127 specifications or those having equivalent or higher strength shall be used and shall be durable to at least 165kgf/cm2 or 16.5Mpa pressure. However, for secondary side piping provided with pressure regulating devices, steel pipe that is durable to at least the maximum regulated pressure at 40°C may be used.3.Piping connectors and valves shall be endurable to at least the internal pressure intensity and be provided with proper anti-corrosion treatment.
