Re: [Oil&Gas] Fire Fighting (Sprinkler & Pillar Hydrant)

 

Pak Rifai,

Kalau pressure 1 s/d 1,5 bar mungkin saya masih berani pegang sendiri tuh Nozzle, tapi 3 bar keatas, enggak deh, itu dari pengalaman sendiri loh. 

Wassalam,

Hadi M.

Sependek yg saya tahu, mengutip dari NFPA 14

7.8.1 Minimum Design Pressure for Hydraulically Designed Systems.

7.8.1.1 Hydraulically designed standpipe systems shall be designed to provide the waterflow rate required by Section 7.10

at a minimum residual pressure of 100 psi (6.9 bar) at the outlet of the hydraulically most remote 65-mm (21⁄2-in.) hose

connection and 4.5 bar (65 psi) at the outlet of the hydraulically most remote 38-mm (11⁄2-in.) hose station.

 

Kalau dalam spec kami:

… the pressure shall never exceed 12 barg for 1" and 7 barg for 1-½" systems. If necessary, a pressure control valve can be installed.

Mungkin rekan dari lapangan bisa sharing apakah pressure setinggi ini akan menyebabkan hose menjadi liar waktu digunakan. CMIIW
