Ama-Flanges ensimbi engagqwali (i-flange) abizwa nangokuthi ama-flanges ensimbi engagqwali noma ama-flanges. Kuyingxenye lapho ipayipi futhi ipayipi lixhumeke komunye nomunye. Exhunywe ekugcineni kwepayipi. I-filange yensimbi engenasici inenkinga futhi ingavinjelwa ukuze ama-flanges amabili ensimbi axhunyiwe kahle. I-filange yensimbi engenasici ivaliwe nge-gasket. Ama-flanges ensimbi engagqwali ayizingxenye ezenziwe ngezinsimbi ezivame kakhulu kumapayipi nama-flanges asetshenziswa ngababili. Ku-Plumbing, ama-Flanges asetshenziselwa ukuxhumeka kwepayipi. Kumapayipi adinga ukuxhunywa, kufakwa izinhlobonhlobo zama-flanges, futhi amapayipi aphansi angenawo ama-flanges ane-wire-bonded, futhi ama-flanges we-welding asetshenziswa ekucindezelweni okungenhla kwe-4 kg.

Ukumelana nokugqwala kwamandla ama-flansion angenasici kuya nge-chromium, kepha ngoba i-chromium ingenye yezakhi zensimbi, izindlela zokuvikela zihlukile. Lapho inani le-chromium elingeziwe lingaphezulu kwe-11.7%, ukumelana nokonakala komkhathi kwensimbi kukhuphuka ngokumangazayo, kepha lapho okuqukethwe kwe-chromium kuphakeme, yize ukumelana nokugqwala kusathuthukiswa, akubonakali. Isizathu ukuthi lapho i-Chromium isetshenziselwa insimbi ye-alloy, uhlobo lwe-oxide elingaphezulu kwe-oxide luguqulwe lube yi-oxide engaphezulu kwe-oxide Lokhu kunamathela ngokuqinile i-chromium-rich oxide kuvikela indawo kusuka ku-oxidation eyengeziwe. Le nhlangano ye-oxide inciphile kakhulu, lapho ungabona khona i-luster yemvelo yensimbi yensimbi, inikeze insimbi engenasici endaweni eyingqayizivele. Ngaphezu kwalokho, uma ungqimba olungaphezulu lulimele, ingaphezulu lensimbi eliveziwe lihlangabezana nomkhathi ukuze uzilungise, uguqule ifilimu elithi oxide "futhi uqhubeke nokuvikela. Ngakho-ke, zonke izinto zensimbi ezingenasici zinesici esivamile, okungukuthi, okuqukethwe kwe-chromium kungaphezulu kwe-10,5%.

Ukuxhumeka kwensimbi engenasici kulula ukuyisebenzisa futhi kungamelana nezingcindezi ezinkulu. Ukuxhumeka kwensimbi engenasici kusetshenziswa kakhulu kumapayipi wezimboni. Ekhaya, ububanzi bepayipi buncane futhi bucindezelwe kakhulu, futhi izingxoxo ezingenasici zensimbi azibonakali. Uma usekamelweni le-boiler noma indawo yokukhiqiza, amapayipi angenasisekelo athambile nemishini kukhona yonke indawo.
