Kwi-AWWA C207-07, i-Class E hub flanges luhlobo oluthile lwe-flange eyenzelwe ukusetyenziswa kwiinkqubo zokubonelela ngamanzi. I-American Water Works Association (AWWA) iseke imigangatho yeeflange zepayipi zensimbi ezisetyenziswa kwiinkqubo zamanzi, kunye neClass E hub flanges ziyingxenye yalo mgangatho.
I-Class E hub flanges yenzelwe izicelo ezinoxinzelelo oluphezulu lokusebenza xa kuthelekiswa neeflange zeClass D. Ezi flange zidla ngokusetyenziswa kumaziko okucoca amanzi, amaziko amanzi amdaka, kunye nothungelwano lonikezelo lwamanzi lukamasipala apho iimfuno zoxinzelelo zingqongqo.
Kwi-AWWA C207-07, i-Class E hub flanges ihlelwa ngokusekelwe kuxinzelelo lwazo kwaye zenziwa ukuhlangabezana neemfuno ezithile zoyilo. Umgangatho uxela imilinganiselo eyahlukeneyo enje ngedayamitha yeflange, idiameter yebholithi yomngxuma, isangqa sebholiti idayamitha, imilinganiselo yehub, imilinganiselo ejongeneyo, kunye nobungqingqwa bobukhulu beeflange zeKlasi E.
Iiflange zeehabhu zeKlasi E ziqhele ukwenziwa kwizinto ezifana nekhabhoni yentsimbi okanye intsimbi engatyiwayo ukuqinisekisa ukuqina kunye nokumelana nokudumba kwizicelo zamanzi. I-hub ephakanyisiweyo embindini we-flange inika amandla okongeziweyo kunye nenkxaso xa idibanisa kwimibhobho okanye i-valve.
Iinkcukacha ezichazwe kwi-AWWA C207-07 Itheyibhile 4 yee-hub flanges ze-Class E ziqinisekisa ukuba ii-flanges zihlangabezana neemfuno ezingqongqo zezicelo ze-waterworks kunye nokubonelela ngoqhagamshelo oluthembekileyo, olungenalo ukuvuza kwiinkqubo zokuhambisa amanzi ngoxinzelelo oluphezulu.
Isishwankathelo, i-Class E hub flanges echazwe kwi-AWWA C207-07 Itheyibhile yesi-4 idlala indima ebalulekileyo kwiinkqubo zokubonelela ngamanzi, inikezela ngoqhagamshelwano olukhuselekileyo noluthembekileyo lweziseko zemibhobho kwiindawo zokucocwa kwamanzi, iindawo zokucocwa kwamanzi amdaka, kunye nothungelwano lokuhanjiswa kwamanzi kamasipala.
