I-flange, eyaziwa nangokuthi i-flange noma i-flange. I-flange iyingxenye ehlanganisa ama-shafts futhi isetshenziselwa ukuxhuma iziphetho zamapayipi; Okunye okuwusizo ama-flanges endaweni yokungena nokuphuma kwemishini, esetshenziselwa ukuxhuma amadivaysi amabili, njengama-flanges we-gearbox. Ukuxhumana kwe-flange noma okuhlangene kwe-flange kubhekisela ekuxhumekeni okukhiphekayo okwakhiwa inhlanganisela yama-flange, ama-gaskets, nama-bolt axhunywe ndawonye njengesakhiwo sokuvala. I-pipeline flange isho i-flange esetshenziselwa ukubhobhoza okokusebenza kwamapayipi, futhi uma isetshenziswa emshinini, ibhekisela ekungeneni nasekuphumeni kwezinto zokusebenza. Ngokwamazinga ahlukene okucindezela okulinganiselwe kwama-valve, ama-flange anamazinga ahlukene okucindezela amiswa kuma-flange amapayipi. Mayelana nalokhu, onjiniyela baseJalimane abavela ku-Ward WODE bethula amazinga okucindezela ama-flange amaningana avame ukusetshenziswa ngokwezindinganiso zamazwe ngamazwe:

Ngokusho kwe-ASME B16.5, ama-flange ensimbi anezilinganiso zokucindezela ezingu-7: I-Class150-300-400-600-900-1500-2500 (ama-flange ajwayelekile kazwelonke ane-PN0.6, PN1.0, PN1.6, PN2.5, PN4 .0, PN6.4, PN10, PN16, PN25, Izilinganiso ze-PN32Mpa)

Isilinganiso sokucindezela kwe-flange sicacile kakhulu. Ama-flange e-Class300 angakwazi ukumelana nengcindezi enkulu kune-Class150 ngoba ama-flange e-Class300 adinga ukwenziwa ngezinto eziningi ukuze amelane nengcindezi enkulu. Nokho, amandla okucindezela ama-flange athonywa izici eziningi. Isilinganiso sokucindezela kwe-flange sivezwa ngamaphawundi, futhi kunezindlela ezihlukene zokumela isilinganiso sokucindezela. Isibonelo, izincazelo ze-150Lb, 150Lbs, 150 #, kanye ne-Class150 ziyefana.
