Ama-flange ensimbi engagqwali (i-flange) abizwa nangokuthi ama-flange ensimbi engagqwali noma ama-flange.Kuyingxenye lapho ipayipi nepayipi kuxhunywe komunye nomunye.Ixhunywe ekugcineni kwepayipi.I-flange yensimbi engagqwali inezimbobo futhi ingabotshwa ukuze ama-flange amabili ensimbi engagqwali axhumeke ngokuqinile.I-flange yensimbi engagqwali ivalwe nge-gasket.Ama-flange ensimbi engagqwali ayizingxenye ezimise okwe-disc ezivame kakhulu kumapayipi nama-flanges asetshenziswa ngababili.Emapayipini, ama-flange asetshenziselwa ngokuyinhloko ukuxhuma amapayipi.Emapayipini adinga ukuxhunywa, ama-flange ahlukahlukene afakiwe, futhi amapayipi aphansi okucindezela angasebenzisa ama-flange ahlanganiswe ngocingo, futhi ama-welding flanges asetshenziselwa izingcindezi ezingaphezu kuka-4 kg.

Ukumelana nokugqwala kwama-flange ensimbi engagqwali kuncike ku-chromium, kodwa ngenxa yokuthi i-chromium ingenye yezingxenye zensimbi, izindlela zokuvikela zihlukile.Uma inani le-chromium elingeziwe lingaphezu kuka-11.7%, ukumelana nokugqwala komkhathi wensimbi kukhuphuka ngokuphawulekayo, kodwa lapho okuqukethwe kwe-chromium kuphezulu, nakuba ukumelana nokugqwala kusathuthukisiwe, akubonakali.Isizathu siwukuthi lapho i-chromium isetshenziselwa ukwenza insimbi ye-alloy, uhlobo lwe-oxide engaphezulu luyashintshwa lube i-oxide engaphezulu efana naleyo eyakhiwe ngensimbi ehlanzekile ye-chromium.Le oxide enamathela ngokuqinile ecebile nge-chromium ivikela ingaphezulu ekuqhubekeleni phambili kwe-oxidation.Lolu ngqimba lwe-oxide luncane kakhulu, okwazi ngalo ukubona ukucwebezela kwemvelo kwendawo yensimbi, okunikeza insimbi engagqwali indawo eyingqayizivele.Ngaphezu kwalokho, uma ungqimba lwangaphezulu lonakalisiwe, indawo yensimbi eveziwe isabela nomkhathi ukuze izilungise, iguqule i-oxide "passivation film" futhi iqhubeke nokuvikela.Ngakho-ke, zonke izakhi zensimbi ezingenasici zinesici esivamile, okungukuthi, okuqukethwe kwe-chromium kungaphezu kuka-10.5%.

I-stainless steel flange uxhumano kulula ukuyisebenzisa futhi ingamelana nezingcindezi ezinkulu.Ukuxhumana kwe-flange yensimbi engenasici kusetshenziswa kakhulu kumapayipi ezimboni.Ekhaya, ububanzi bepayipi buncane futhi buphansi, futhi ukuxhumeka kwe-flange yensimbi engagqwali akubonakali.Uma usendlini yokubhayela noma indawo yokukhiqiza, amapayipi nemishini yensimbi engagqwali yonke indawo.
