Muyezo wapadziko lonse wa AWWA c207 ndikuzembera pa flange yomwe ili pansi pa mulingo uwu

Muyezo wa AWWA C207 udapangidwa ndi American Water Works Association (AWWA) ndipo cholinga chake ndi tsatanetsatane wa magawo olumikizirana ndi flange mumayendedwe amadzi am'matauni ndi ngalande zapamadzi. Dzina lonse la muyezo uwu ndi "AWWA C207 - Zitsulo za Pipe za Steel for Waterworks Service - Size 4 In. Kupyolera mu 144 In. (100 mm Kupyolera mu 3,600 mm)”.

PansiAWWA C207 muyezo, Slip-On Flangendi wamba flange mtundu ntchito kulumikiza mapaipi, mavavu, mapampu ndi zida zina mapaipi. Nazi zina zokhuza khosi lathyathyathya weld flanges pa muyezo AWWA C207:

Slip-On hubbed flangendi flange yomwe nthawi zambiri imakhala ndi nkhope yathyathyathya ndipo imagwiritsidwa ntchito polumikizana ndi mapaipi. Ilinso ndi gawo la khosi la ulusi kuti lilumikizane ndi flange ya ulusi. Utali wa khosi la flanges wa khosi nthawi zambiri umasiyanasiyana malinga ndi zofunikira kuti zigwirizane ndi zofunikira zenizeni.

Kukula:

TheAWWA C207 muyezolimatchula khosi lathyathyathya kuwotcherera flanges mu makulidwe kuyambira 4 mu. (100 mm) kuti 144 mu. (3,600 mm) kwa zosiyanasiyana chitoliro diameters.

Gulu la Pressure:

Malinga ndi muyezo wa AWWA C207, ma flanges okhala ndi khosi lathyathyathya nthawi zambiri amagawidwa m'magulu osiyanasiyana okakamiza kuti akwaniritse zofunikira zosiyanasiyana zogwirira ntchito. Magawo osiyanasiyana okakamiza ndi oyenera kugwiritsa ntchito zosiyanasiyana komanso ma projekiti aumisiri.

Zofunika:

Slip-On hubbed Flange nthawi zambiri amapangidwa ndi chitsulo cha kaboni, chitsulo chosapanga dzimbiri kapena zida zina zoyenera zachitsulo kuti zigwirizane ndi malo ogwirira ntchito ndi media. Kusankhidwa kwa zinthu kudzatengera zofunikira za pulojekiti ndi mikhalidwe yogwiritsira ntchito mapaipi.

Zofunikira pakupanga:

Muyezo wa AWWA C207 umaphatikizapo zofunikira pamapangidwe atuluka pa ma flanges opangidwamonga miyeso, kulolerana, ulusi, ndi mabowo oponyedwa. Zofunikira izi zimathandiza kuonetsetsa kuti flange ikugwira ntchito komanso yodalirika pakuyika ndikugwiritsa ntchito.

Malo ofunsira:

Slip-On hubbed Flanges amagwiritsidwa ntchito nthawi zambiri m'mapaipi operekera madzi am'tauni ndi mapaipi amadzi, kuphatikiza madzi am'tauni, madzi am'mafakitale, kuyeretsa madzi ndi kuyeretsa madzi oyipa ndi ntchito zina. Amagwiritsidwa ntchito kulumikiza mapaipi, mavavu, mapampu ndi zida zina zapaipi kuti zitsimikizire kudalirika ndi chitetezo cha mapaipi.

Mwachidule, ma flanges okhala ndi makosi ndi mtundu wamba wa flange womwe umagwirizana ndi miyezo ya AWWA C207 ndipo amagwiritsidwa ntchito kwambiri pama projekiti amadzi am'matauni ndi madzi oipa. flange Izi zikugwirizana mipope kudzera kuwotcherera lathyathyathya ndipo ali khosi kwa ulusi kugwirizana, amene angagwiritsidwe ntchito zosiyanasiyana chitoliro diameters ndi ntchito kuthamanga misinkhu. Kusankhidwa kwa ma flanges okhala ndi khosi lathyathyathya kuyenera kuganiziridwa potengera zosowa za projekiti komanso zofunikira pakupanga mapaipi.
