Izinga le-AWWA C207 lathuthukiswa yi-American Water Works Association (AWWA) futhi lihloselwe kakhulu ukucaciswa okujwayelekile kwezingxenye zokuxhunywa kwe-flange kumasistimu kamasipala okuphakela amanzi kanye nendle. Igama eliphelele laleli zinga lithi “AWWA C207 – Steel Pipe Flanges for Waterworks Service – Osayizi 4 In. Nge-144 In. (100 mm Ngokuya ku-3,600 mm)”.
NgaphansiI-AWWA C207 ejwayelekile, i-Slip-On Flangeuhlobo oluvamile lwe-flange olusetshenziselwa ukuxhuma amapayipi, ama-valve, amaphampu nezinye izinto zokusebenza zamapayipi. Nansi eminye imininingwane mayelana nama-flange weld weld anentamo ngokwezinga le-AWWA C207:
I-Slip-On enehabhu ye-flangeiyi-flange evame ukuba nobuso obuyisicaba futhi isetshenziselwa ukuxhuma okuyisicaba ngamapayipi. Iphinde ibe nengxenye yentamo enentambo yokuxhuma i-flange enentambo. Ubude bentamo yama-flanges anentamo ngokuvamile buyahlukahluka njengoba kudingeka ukuze kuhlangatshezwane nezidingo ezithile zokuxhunywa kwamapayipi.
Ibanga likasayizi:
II-AWWA C207 ejwayelekileicacisa ama-flange e-weld anentamo ayisicaba ngobukhulu asukela ku-4 in. (100 mm) kuya ku-144 in. (3,600 mm) kumadayimitha ahlukahlukene wamapayipi.
Ikilasi Lokucindezela:
Ngokwezinga le-AWWA C207, ama-flange we-weld flat anentamo ngokuvamile ahlukaniswa amakilasi ahlukene okucindezela ukuze abhekane nezidingo zengcindezi yokusebenza ehlukene. Amazinga ahlukene okucindezela afanele izinhlelo zokusebenza ezahlukene namaphrojekthi wobunjiniyela.
Okubalulekile:
I-Slip-On hubbed Flange ngokuvamile yenziwe nge-carbon steel, insimbi engagqwali noma ezinye izinto zensimbi ezifanele ukuzivumelanisa nezimo zokusebenza ezihlukene kanye nemidiya. Ukukhethwa kwezinto ezibonakalayo kuzosekelwe ezidingweni ezithile zephrojekthi kanye nezimo zokusetshenziswa zohlelo lwamapayipi.
Izidingo zokuklama:
Izinga le-AWWA C207 lihlanganisa izidingo zokuklama zeslip on flanges hubbednjengobukhulu, ukubekezelelana, izintambo, nezimbobo ezithenjiwe. Lezi zidingo zisiza ukuqinisekisa ukusebenza kwe-flange nokuthembeka phakathi nokufakwa nokusetshenziswa.
Izindawo zokufaka isicelo:
Ama-Slip-On hubbed Flanges avame ukusetshenziswa ezinhlelweni zikamasipala zokuphakela amanzi kanye namapayipi endle, okuhlanganisa ukuhlinzekwa kwamanzi kamasipala, ukuhlinzekwa kwamanzi ezimbonini, ukuhlanzwa kwamanzi kanye nokuhlanza amanzi angcolile nezinye izinhlelo zokusebenza. Asetshenziselwa ukuxhuma amapayipi, ama-valve, amaphampu kanye nezinye izinto zokusebenza zamapayipi ukuze kuqinisekiswe ukwethembeka nokuphepha kwesistimu yamapayipi.
Kafushane, ama-flange weld weld anentamo awuhlobo olujwayelekile lwe-flange oluhambisana namazinga e-AWWA C207 futhi asetshenziswa kakhulu kumaphrojekthi kamasipala wamanzi namanzi angcolile. Le flange ixhuma amapayipi ngokusebenzisa i-welding eyisicaba futhi inentamo yokuxhuma okufakwe intambo, engasetshenziswa kumadayimitha ahlukahlukene wamapayipi kanye namazinga okucindezela okusebenzayo. Ukukhethwa kwama-flange weld weld kufanele kucatshangelwe ngokusekelwe ezidingweni ezithile zephrojekthi kanye nezidingo zokuklama amapayipi.
