Chii chinonzi AWWA Standard yeDuctile Iron Popes?

Mapaipi esimbi akagadzirwa nesimbi, dzinoshandiswa zvakanyanya nekuda kwekugara kwenguva refu uye kusimba kwadzo, dzinogadzirwa zvichienderana nezvinodiwa zvakasiyana-siyana, kusanganisira zviyero zveAmerica neEurope. Mitemo iyi inopa gwara remitsetse pahukuru, ukobvu, nezvimwe zvinhu zvakakosha kuti ive nechokwadi chekuti mapaipi anosangana nekushanda kunodiwa uye mwero wemhando yekushandiswa kwakasiyana. Pazasi pane zviyero zvakakosha uye ukobvu zvichienderana neAmerican (ANSI/AWWA).

AMERICAN SPECS(ANSI/AWWA C151)

OD/ ID, WT/ Kirasi

Sangano reAmerican Water Works Association (AWWA) rinopa marongero emapombi eDI kuburikidza neANSI/AWWA CI51/A21.51. Marongero aya anofukidza dhayamita dzakasiyana-siyana uye makirasi ekumanikidzwa:

Dhayamita: Saizi dzinozivikanwa dzemapaipi esimbi ane ductile pasi pemitemo yeAWWA dzinotangira pamainji matatu (anenge 76 mm) kusvika pamainji makumi matanhatu nemana (anenge 1,626 mm).

Kirasi Yeukobvu: Mitemo yeAWWA inotsanangura makirasi eukobvu kwete ukobvu hwemadziro chaiwo. Makirasi aya anotsanangurwa seKirasi 50 kusvika kuKirasi 56 kumapombi ane dhayamita inosvika 24 inches, kirasi yega yega inoenderana neukobvu hwakasiyana hwemadziro hwakagadzirirwa kutsungirira mazinga akasiyana ekumanikidzwa kwemukati uye mitoro yekunze.

Kirasi Yekumanikidzwa: Mapaipi aya anowanikwawo muzvikamu zvemadhigirii, anowanzo bva pa150 psi (inenge 1,034 kPa) kusvika pa350psi (inenge 2,413 kPa), zvichiratidza kumanikidzwa kwakanyanya kushanda kunoitwa nemapaipi.

Dhayamita yemukati (UNL/CL/DCL): dhayamita yemukati inosiyana zvichienderana nekuvapo kwemukati memadziro (UNL = pombi isina mutsetse, kureva simbi isina ductile,CL = simende yakapetwa, DCL = Simende yakapetwa kaviri)

Cherechedza kuti:

ANSI/AWWA C151/A21.51: Mutemo wekuAmerica wemapaipi esimbi ane ductile emvura nezvimwe zvinwiwa.

ANSI/AWWA C115/A21.15: Yemapaipi esimbi ane ductile akaputirwa.

Heino chati yehukuru ine saizi nehuremu hwemapaipi esimbi anoshandiswa pakufambisa mvura (Nps 3″ kusvika 54″ - Kirasi 53, ndiyo inonyanya kushandiswa pakushandisa mvura):

Kureba kwepombi (ANSI/AWWA):Pasi pemitemo yeAmerican National Standards Institute (ANSl neAmerican Water Works Association (AWWA) kunyanya ANSI/AWWA C151/A21.5l, mapaipi esimbi anowanzo shandiswa muhurefu hunotevera:

Kureba Kwekuisa: Kureba kwekuisa kwemapaipi esimbi anoshandiswa mupurasitiki muUnited States kunowanzova mamita 5.5 kana mamita 6.l emuviri mukuru wepaipi, tisingabatanidzi kureba kwejoini kana bhero.

Kureba Kwakajairwa: Mamwe mapurojekiti angada mapaipi ane hurefu hwakasiyana kuti agadzirire dhizaini yakasiyana, uye vagadziri vanogona kupa mapaipi ane hurefu hwakasiyana zvichienderana nezvinodiwa nepurojekiti.
