Iiflange zensimbi ezingenasici (i-flange) zikwabizwa ngokuba yi-stainless steel flanges okanye i-flanges. Iyinxalenye apho umbhobho kunye nombhobho zixhunywe omnye komnye. Iqhagamshelwe ekupheleni kombhobho. I-stainless steel flange ine-perforations kwaye inokubotshwa ukuze iiflange ezimbini zensimbi ezingenasici zidibaniswe ngokuqinileyo. I-flange yensimbi engenasici ivalwe nge-gasket. Iiflange zensimbi ezingenasici ziyinxalenye yediskhi ezixhaphake kakhulu kwimibhobho yamanzi kunye neeflange zisetyenziswa ngababini. Kwimibhobho, iiflange zisetyenziselwa ukudibanisa imibhobho. Kwiimibhobho ezifuna ukuxhunywa, iintlobo ezahlukeneyo ze-flange zifakwe, kwaye imibhobho ephantsi yoxinzelelo ingasebenzisa i-wire-bounded flanges, kunye ne-welding flanges isetyenziswe kwiingcinezelo ezingaphezu kwe-4 kg.

Ukuxhatshazwa kwe-corrosion ye-stainless steel flanges kuxhomekeke kwi-chromium, kodwa ngenxa yokuba i-chromium yenye yezinto zentsimbi, iindlela zokukhusela zihlukile. Xa isixa se-chromium esongeziweyo singaphezulu kwe-11.7%, ukuxhathisa kwe-atmospheric corrosion of the steel kwanda ngokuphawulekayo, kodwa xa umxholo we-chromium uphezulu, nangona ukuxhathisa kwe-corrosion kusaphuculwe, akubonakali. Isizathu kukuba xa i-chromium isetyenziselwa intsimbi ye-alloy, uhlobo lwe-oxide ye-surface oxide iguqulwa ibe yi-oxide yomhlaba efana naleyo yenziwe kwintsimbi ecocekileyo yechromium. Le oxide ibambelela ngokuqinileyo kwichromium-rich ikhusela umphezulu kwi-oxidation eyongezelelweyo. Lo maleko weoksidi ubhityile kakhulu, apho unokubona ubukhazikhazi bendalo bomphezulu wentsimbi, unika intsimbi engatyiwayo indawo eyodwa. Ngaphezu koko, ukuba umaleko womphezulu wonakaliswe, indawo yentsimbi eveziweyo isabela nomoya ukuze ilungiswe ngokwawo, iguqule i-oxide "passivation film" kwaye iqhubeke nokukhusela. Ngoko ke, zonke izinto zensimbi ezingenasici zinempawu eziqhelekileyo, oko kukuthi, umxholo we-chromium ungaphezu kwe-10.5%.

Uxhulumaniso lwe-flange yensimbi engenasici kulula ukuyisebenzisa kwaye inokumelana noxinzelelo olukhulu. Ukudityaniswa kwe-flange yensimbi engenasici isetyenziswa kakhulu kwimibhobho yeshishini. Ekhaya, ububanzi bombhobho buncinci kwaye buphantsi, kwaye i-stainless steel flange uxhumano alubonakali. Ukuba ukwigumbi lebhoyila okanye indawo yokuvelisa, imibhobho yentsimbi engenastainless flanged kunye nezixhobo zikuyo yonke indawo.
