Kodi muyezo wa AWWA wa mapaipi achitsulo a Ductile ndi uti?

Mapaipi achitsulo opangidwa ndi ductile, zomwe zimagwiritsidwa ntchito kwambiri chifukwa cha kulimba kwawo komanso kulimba kwawo, zimapangidwa motsatira miyezo yosiyanasiyana, kuphatikiza miyezo ya ku America ndi ku Europe. Miyezo iyi imapereka mizere yotsogolera pa miyeso, makulidwe, ndi zinthu zina zofunika kwambiri kuti zitsimikizire kuti mapaipi akukwaniritsa magwiridwe antchito ndi khalidwe lofunikira pa ntchito zosiyanasiyana. Pansipa pali miyeso ndi makulidwe ofunikira malinga ndi American (ANSI/AWWA).

AMERICAN SPECS(ANSI/AWWA C151)

OD/ ID, WT/ Kalasi

Bungwe la American Water Works Association (AWWA) limapereka malangizo a mapaipi a DI kudzera mu ANSI/AWWA CI51/A21.51. Malangizo awa akuphatikizapo mitundu yosiyanasiyana ya ma diameter ndi magulu a kuthamanga:

M'mimba mwake: Kukula kwa mapaipi achitsulo chosungunuka pansi pa miyezo ya AWWA kumayambira mainchesi 3 (pafupifupi 76 mm) mpaka mainchesi 64 (pafupifupi 1,626 mm).

Kalasi Yokhuthala: Miyezo ya AWWA imatchula magulu a makulidwe m'malo mwa makulidwe enieni a khoma. Magulu awa adapangidwa kuti akhale Kalasi 50 mpaka Kalasi 56 ya mapaipi okhala ndi mainchesi 24 m'mimba mwake, ndipo kalasi iliyonse imagwirizana ndi makulidwe osiyanasiyana a khoma omwe adapangidwa kuti athe kupirira kupsinjika kwamkati ndi katundu wakunja.

Kalasi Yokakamiza: Mapaipi amagawidwanso m'magulu okakamiza, nthawi zambiri kuyambira 150 psi (pafupifupi 1,034 kPa) mpaka 350psi (pafupifupi 2,413 kPa), zomwe zikusonyeza kuthamanga kwakukulu komwe mapaipi amapangidwira kugwira.

Mkati mwake (UNL/CL/DCL): m'mimba mwake mkati mwake umasiyana malinga ndi kupezeka kwa zinthu zamkati (UNL = chitoliro chopanda mzere, mwachitsanzo chitsulo chopanda ductile,CL = simenti yolumikizidwa, DCL = Simenti iwiri yolumikizidwa)

Zindikirani kuti:

ANSI/AWWA C151/A21.51: Muyezo waku America wa mapaipi achitsulo opangidwa ndi ductile amadzi ndi zakumwa zina.

ANSI/AWWA C115/A21.15: Pa mapaipi achitsulo opangidwa ndi ductile.

Nayi tchati cha kukula ndi miyeso ndi kulemera kwa mapaipi achitsulo opangidwa ndi ductile kuti atumize madzi (Nps 3″ mpaka 54″ – Gulu 53, lomwe limagwiritsidwa ntchito kwambiri pakugwiritsa ntchito madzi):

Kutalika kwa Mapaipi (ANSI/AWWA):Malinga ndi American National Standards Institute (ANSl ndi American Water Works Association (AWWA) specifications makamaka ANSI/AWWA C151/A21.5l, mapaipi achitsulo opangidwa ndi ductile nthawi zambiri amaperekedwa m'litali motere:

Kutalika kwa Malo Oikira: Kutalika kwa malo oikira mapaipi achitsulo chopangidwa ndi ductile ku United States nthawi zambiri kumakhala mamita 5.5 kapena mamita 6.l pa thupi lalikulu la chitolirocho, osaphatikizapo kutalika kwa cholumikizira kapena belu.

Kutalika Kwapadera: Mapulojekiti ena angafunike mapaipi a kutalika kwina kuti agwirizane ndi kapangidwe kake, ndipo opanga amatha kupereka mapaipi a kutalika kwina malinga ndi zomwe polojekitiyo ikufuna.
