I-AWWA C207 empeleni isho izinga le-C207 elithuthukiswe yi-American Water Works Association (AWWA). Kuwukucaciswa okujwayelekile kwama-flange amapayipi okuhambisa amanzi, i-drainage, nezinye izinhlelo zokuthutha uketshezi.
Uhlobo lwe-Flange:
Izinga le-AWWA C207 lihlanganisa izinhlobo ezahlukene zama-flange, okuhlanganisaizimpumputhe flange, weld neck flanges, slip kuma-flanges, ama-flanges anemicu, njll. Uhlobo ngalunye lwe-flange lunezimo zalo eziqondile zohlelo lokusebenza kanye nokusetshenziswa.
Izinga Lokucindezela:
Izinga le-AWWA C207 lichaza ama-flange anezigaba ezihlukene zokucindezela. Izilinganiso zokucindezela ezivamile Ikilasi B, Ikilasi D, Ikilasi E kanye Nekilasi F. Ibanga ngalinye lihambisana nezimfuneko ezihlukene zengcindezi nezinga lokushisa ukuze kuhlangatshezwane nezidingo ezihlukahlukene zobunjiniyela.
Ibanga losayizi:
Izinga le-AWWA C207 licacisa ububanzi bobubanzi be-flange ngosayizi abahlukene, ukusuka kumayintshi angu-4 ukuya kwangu-72 amayintshi. Okungukuthi, i-DN100-DN1800, okusho ukuthi izinga lifanele ukuxhumeka nokusetshenziswa kwamadayimitha ahlukahlukene wamapayipi.
Ibanga elijwayelekile:
I-AWWA C207 ikakhulukazi ibandakanya izindinganiso zamapayipi amapayipi, okuhlanganisa ama-flange enziwe nge-carbon steel, insimbi engagqwali, ne-alloy steel. Ilungele inhlobonhlobo yamapayipi amapayipi emikhakheni yezinsiza, zezimboni, ezohwebo nezokwakha.
Ukuqashelwa kwamazwe ngamazwe:
Nakuba i-AWWA iyinhlangano ezinze e-US, indinganiso ye-AWWA C207 isetshenziswa kabanzi emhlabeni wonke futhi yamukelwa kabanzi futhi yamukelwa kabanzi. Leli zinga lamukelwa kumaphrojekthi wokuphakelwa kwamanzi, izinhlelo zokudonsa amanzi kanye nezinhlelo zokuthutha uketshezi emazweni amaningi nasezifundeni.
I-AWWA C207 iyindinganiso esetshenziselwa amapayipi amapayipi futhi inokubili okuhle nokubi.
Inzuzo:
1. Ukumiswa: I-AWWA C207 ihlinzeka ngedizayini esezingeni kanye nezidingo zokukhiqiza zamapayipi amapayipi, ukuze abakhiqizi abahlukene nabahlinzeki bempahla bakwazi ukulandela ukucaciswa okufanayo kokukhiqizwa, ngaleyo ndlela kuqinisekiswe ikhwalithi yomkhiqizo nokuvumelana.
2. Uhlu olubanzi lwesicelo: Leli zinga lisebenza kuma-flanges enziwe ngezinto ezihlukahlukene, okuhlanganisa insimbi, insimbi ekhonjiwe, insimbi ye-alloy nensimbi engagqwali, njll., ukuhlangabezana nezidingo ezahlukene zobunjiniyela.
3. Amazinga okucindezela ahlukahlukene: I-AWWA C207 ihlanganisa ama-flange anamazinga ahlukahlukene okucindezela, okuvumela onjiniyela ukuba bakhethe uhlobo olufanele lwe-flange nezinga lokucindezela ngokuvumelana nezidingo zamaphrojekthi athile.
4. Ukuthembeka: Ama-Flange avumelana nezinga le-AWWA C207 aye aklanywa ngokuqinile nezidingo zokuhlola, anokwethenjelwa okuphezulu nokuhlala isikhathi eside, futhi asiza ekuqinisekiseni ukusebenza okuphephile nokuzinzile kohlelo lwamapayipi.
Okubi:
1. Izindinganiso zangaphambili: I-AWWA C207 iyindinganiso yangaphambili futhi ingase ingathobeli ngokugcwele izimfuneko zakamuva zobuchwepheshe nezobunjiniyela kwezinye izici. Njengoba ubuchwepheshe buqhubeka nokuvela, ezinye izinto ezintsha nemiklamo ingase ingambozwa ngokwanele yileli zinga.
2. Ayisebenzi kuzo zonke izimo: Nakuba i-AWWA C207 ifaneleka ukuvuleka kwamapayipi ezimweni eziningi, amanye amazinga aqinile angase adingeke kumaphrojekthi athile wobunjiniyela noma izimfuneko ezithile zempahla.
3. Isivinini sokubuyekeza esinensayo: Inqubo yokubuyekeza evamile ingase ihambe kancane, okubangele ukuthi obunye ubuchwepheshe obusha nezinqubo ezihamba phambili zingafakwa esilinganisweni ngesikhathi, okwenza izinga lihambe kancane ukuze lihambisane nezikhathi.
Ihlanganiswe ndawonye, i-AWWA C207 isebenza ezimweni eziningi njengezinga lemboni, ehlinzeka ngesethi eqinile yedizayini nemihlahlandlela yokukhiqiza esiza ukuqinisekisa ikhwalithi nokusebenza kwamapayipi amapayipi. Kodwa-ke, ezinhlelweni ezisebenzayo, onjiniyela nabaklami badinga ukucabangela ngokugcwele izidingo zamaphrojekthi athile, futhi uma kunesidingo, babhekisele kwamanye amazinga akamuva kanye nezindlela ezihamba phambili zokuhlangabezana nezidingo ezithile.
