Flange wejiga kor u kacay(RF) waa sahlan tahay in la aqoonsado maadaama aagga dusha sare ee gasket uu ka sarreeyo xariiqda bolting eegarab.
Waji kor u kacaygarabwaxay la jaanqaadi kartaa noocyo kala duwan oo baakadaha flange ah, oo u dhexeeya dabaq ilaa kuwa biraha birta ah iyo noocyada macdanaha ah (sida, tusaale ahaan, gaasaska jaakadaha leh iyo gaasaska boogaha wareega), giraanti ama weji buuxa.
Baaxadda ugu weyn ee naqshadeynta flange wejiga ee kor loo qaaday waa in la saaro cadaadiska labada garab ee isku dhejisan ee dusha yar iyo kordhinta xoogga shaabadda.
Dhererka wejiga sare wuxuu ku xiran yahaygarabQiimaynta cadaadiska sida lagu qeexay qeexida ASME B16.5 (darajooyinka cadaadiska 150 iyo 300, dhererku waa 1.6 mm ama 1/16 inch, fasalada 400 ilaa 2500, dhererka wejiga kor u kacay waa qiyaastii 6.4 mm, ama 1/4 inji).
Dhammaadka flange ee ugu caansan ee ASME B16.5 RF flanges waa 125 ilaa 250 micron Ra (3 ilaa 6 micron Ra). Wejiga kor u kacaya waa, marka loo eego ASME B16.5, wejiga flange-ga caadiga ah ee soo saarayaasha (tani macnaheedu waa in iibsaduhu uu u kala horreeyo haddii weji kale loo baahan yahay, sida weji fidsan ama giraanta giraanta).
Garaafka wejiga ee kor loo qaaday ayaa ah nooca flange ee ugu iibinta badan, ugu yaraan codsiyada kiimikaad ee petrochemical.
