Ikizamini cya Hydrostatic
Buri burebure bwa pipe ruzageragezwa nuwabikoze kumuvuduko wa hydrostatike uzabyara urukuta rwa pipe stlet stross ntabwo ari munsi ya 60% yimbaraga zagenwe kubushyuhe bwicyumba. Umuvuduko ugomba kugenwa n'igereranya rikurikira:
P = 2st / d
Itandukaniro riremewe muburyo burebire kandi bukoreshwa
Buri burebure bw'umuyoboro bugomba gupimwa ukundi kandi uburemere bwayo ntibushobora gutandukana inshuro zirenga 10% cyangwa 5.5% mu buremere bwayo bwa kiriyaya, kubarwa ukoresheje uburebure bwayo n'uburemere bwayo.
Diameter yo hanze ntishobora gutandukana kurenza ± 1% uhereye kumurongo wasobanuwe hanze.
Ubunini bw'urukuta umwanya uwariwo wose ntibushobora kurenga 12.5% munsi yurukuta rwagenwe.
Uburebure
Uburebure bumwe: 16 kugeza kuri 25 (4.88 kugeza 7.62m)
Uburebure bubiri: hejuru ya metero 25ft (7.62 kugeza 10.67m)
Uburebure bumwe: Itandukaniro ryemewe ± 1in
Iherezo
Pie ibirundo bigomba guhanara birangira, kandi abari mu ntego bazavaho
Iyo umuyoboro urangiye ugaragazwa no kuba urwenya urangira, inguni igomba kuba impamyabumenyi 30 kugeza 35
