AWWA C207-07 ni igipimo cyashyizwe ahagaragara n’ishyirahamwe ry’amazi muri Amerika (AWWA) ryerekana ibipimo, ubworoherane, hamwe n’ibikoresho bya flanges ya feri ikoreshwa muri sisitemu yo gukora amazi. Icyiciro D hub flanges yagenewe gukoreshwa murwego rwo hejuru rwumuvuduko mwinshi muri sisitemu yo gukwirakwiza amazi.
Icyiciro cya D hub flanges yashyizwe mubyiciro ukurikije igipimo cyabyo kandi ikoreshwa mubitunganya amazi, ibikoresho by’amazi, hamwe n’imiyoboro itanga amazi. Iyi flanges yashizweho kugirango itange ihuza rikomeye kandi ryizewe hagati yimiyoboro, indangagaciro, hamwe nibikoresho bikoreshwa mumazi.
Muri AWWA C207-07, Icyiciro cya D hub cyerekanwe hashingiwe ku bipimo bitandukanye, birimo diameter ya flange, umwobo wa diameter, umuzenguruko wa bolt umurambararo, ibipimo bya hub, ureba ibipimo, hamwe nubunini bwihariye. Ibi bisobanuro byemeza ko flanges yujuje ubuziranenge busabwa kandi igatanga guhuza neza no gufunga mugihe bihujwe na sisitemu yo kuvoma.
Icyiciro cya D hub gisanzwe gikozwe mubikoresho nkibyuma bya karubone cyangwa ibyuma bidafite ingese kugirango harebwe igihe kirekire no kurwanya ruswa. Hub yazamuye hagati ya flange itanga imbaraga ninyongera mugihe uhuza imiyoboro cyangwa valve.
Muri rusange, AWWA C207-07 Icyiciro cya D hub ni ibyingenzi muri sisitemu yo gukwirakwiza amazi, bitanga imiyoboro yizewe kandi idasohoka kumashanyarazi kubikorwa remezo byo gutunganya amazi hamwe n’imiyoboro itanga amazi ya komini.
