Flanges F ring flanges adapangidwa kuti azigwiritsidwa ntchito m'makina ogawa madzi omwe ali ndi kufunikira kwamphamvu kwambiri poyerekeza ndi magulu ena a AWWA C207-18 flanges. Ma flanges awa nthawi zambiri amagwiritsidwa ntchito m'malo omwe mphamvu zogwirira ntchito zimakhala zokwera kwambiri, monga m'malo oyeretsera madzi, malo osungira madzi onyansa, ndi ma network operekera madzi amtawuni.
Mu AWWA C207-18, Class F ring flanges amasankhidwa kutengera kukakamizidwa kwawo ndipo amapangidwa kuti atsimikizire kulimba komanso kudalirika pakugwiritsa ntchito madzi othamanga kwambiri. Muyezowu umatchula miyeso yosiyanasiyana ya ma flange a Gulu F, kuphatikiza m'mimba mwake mozungulira bawuti, kuchuluka kwa mabowo a bawuti, m'mimba mwake wa bolt, makulidwe a flange, kutalika kwa hub, ndi miyeso yoyang'ana.
Ma Flange F a mphete amapangidwa kuchokera ku zinthu zapamwamba kwambiri monga chitsulo cha kaboni kapena chitsulo chosapanga dzimbiri kuti athe kupirira kupsinjika kwambiri komanso dzimbiri zomwe zingachitike pamakina ogawa madzi. Ma flanges amapangidwa kuti apereke kulumikizana kotetezeka komanso kopanda kutayikira pakati pa mapaipi, mavavu, ndi zoyika pamagetsi othamanga kwambiri.
Zomwe zafotokozedwa mu AWWA C207-18 za Class F ring flanges zimatsimikizira kutsata miyezo ndikuwonetsetsa kulumikizidwa koyenera ndi kusindikiza zikayikidwa mu mapaipi omwe amagwira ntchito movutikira kwambiri.
Pomaliza, Class F ring flanges monga momwe zafotokozedwera mu AWWA C207-18 ndizinthu zofunikira pamakina ogawa madzi omwe amafunikira kulumikizana kolimba komanso kotetezeka kuti athe kupirira malo oponderezedwa kwambiri m'malo oyeretsera madzi, malo opangira madzi oyipa, ndi ma network operekera madzi amtawuni.
