Standard for Installation of Fire Safety Devices based on Use and Occupancy Article 181
Matching pipes shall be equipped pursuant to the following provisions:1.Dedicated pipe shall be used, and the diameter of standpipes shall be not les than 100mm. Where the height of the building is less than 50m, the standpipes may be shared by the matching pipe together with indoor fire hydrant; and the pipe diameter shall be not less than 100mm, the diameter of branch pipes not less than 65mm.2.Matching pipes shall comply with CNS No. 6445 and No. 4626, or have the same or higher strength, corrosion resistance and heat endurance. If the design pressure of water delivery exceeds 10kgf/cm2, matching pipes complied with National Standard (CNS) No. 4626, and with the Pipe Number SCH40 or above, or having the same or higher strength, corrosion resistance and heat endurance shall be used.3.Where there are two or more standpipes in a same buildings, cross pipes shall be equipped to interconnect the standpipes.4.Pipe diameter shall be calculated and configured pursuant to the hydraulic calculation.5.Matching pipes shall be enable to endure a pressure not less than 1.5 times the design pressure of water delivery, and last for 30 minutes. Where a relay pump is equipped, the secondary side pipe of the pump shall be enable to endure a water pressure not less than 1.5 times the fully closed lift of the pump.

二、符合CNS六四四五、四六二六規定或具有同等以上強度、耐腐蝕性及耐熱性者。
但其送水設計壓力逾每平方公分十公斤時,應使用符合CNS四六二六管號Sch40以上或具有同等以上強度、耐腐蝕性及耐熱性之配管。
三、同一建築物內裝置二支以上立管時,立管間以橫管連通。
四、管徑依水力計算配置之。
五、能承受送水設計壓力一點五倍以上之水壓,且持續三十分鐘。
但設有中繼幫浦時,幫浦二次側配管,應能承受幫浦全閉揚程一點五倍以上之水壓。
