I-Flange, eyaziwa nangokuthi i-flange noma i-flange. I-Flange iyingxenye exhuma imisele futhi isetshenziselwa ukuxhuma ukuphela kwamapayipi; Ibuye ilusizo ngama-flanges ku-inlet kanye nokuphuma kwemishini, esetshenziselwa ukuxhuma amadivaysi amabili, njengama-gearbox flanges. Ukuxhumana kwe-Flange noma i-Flange ngokuhlangene kubhekisele ekuxhumeni okuguqukayo okwenziwe ngenhlanganisela yama-flanges, ama-gaskets, kanye nama-bolts axhunyiwe ndawonye njengesakhiwo sokubekwa uphawu. I-Pipeline Flange isho i-flange esetshenziselwa amapayipi emishini yepayipi, futhi lapho isetshenziswa kwimishini, isho i-inlet nasezitolo zokuphuma kwemishini. Ngokwamazinga ahlukene wokucindezela ama-valves, ama-flanges anamazinga okucindezela ahlukene alungiselelwe emaphandleni epayipini. Kulokhu, onjiniyela baseJalimane abavela eWard Wode bethula amazinga amancane we-Flange Testops ambalwa ngokusho kwamazinga aphesheya:

Ngokusho kuka-Asme B16.5, ama-Flanges ensimbi anezilinganiso eziyi-7 zokulinganisa: Class150-300-400-600-900-15-2500 (PN1.0 (PN1.0, PN4.6, PN2.5, PN4 .0, PN6.4, PN10, PN16, PN25, PN32MPA Rates)

Isilinganiso sokucindezela kwe-flange sicace bha. Ama-flanges we-Class300 angamelana nengcindezi enkulu kune-Class150 ngoba i-Class300 Flanges idinga ukwenziwa ngezinto eziningi zokumelana nengcindezi enkulu. Kodwa-ke, umthamo ocindezelayo wama-flanges uthonywa yizici eziningi. Ukulinganiswa kwengcindezi kwe-flange kuvezwa ngamakhilogremu, futhi kunezindlela ezahlukahlukene zokumelela isilinganiso sokucindezela. Isibonelo, izincazelo ze-150lb, ama-150lbs, 150 #, kanye ne-class150 ziyefana.
