1. Kune mana polising nzira dzeBi-chikamuSimbi Flange: Manual, muchina, makemikari uye electrochemical. Iyo Corrosion Rishance uye kushongedza kweFlangeinogona kuvandudzwa nekupukuta. Iyo iripo yemagetsi kupukuta mvura yetsvina yesimbi ichiri kushandisa phosphoric acid uye chromic anydride. Mukuita kwekupukuta uye kuchenesa, imwe chromep uye phosphorous ichadzimwa mumarara, zvichikonzera kusvibiswa kwenzvimbo.

2. Passivation firimu ichaumbwa pamusoro peSuplexSimbi Flange, uye iyo nzara yehodhi ichatanga kunyungudusa. Nekuti iyo microcenture yeiyo duplexSimbi FlangeHaisi kuwirirana, iyo zvishoma convex chikamu chechiso chinonyangarika, uye chiyero chekunyungudika chinozove chakakwirira kupfuura icho chekonyera chikamu. Kupararira uye kuumbwa kweMemrane kunenge panguva imwe chete, asi velocities avo vakasiyana. Nekuda kweizvozvo, pamusoro pekunhuhwirira kweiyo bi-phose simbi flange inoderedzwa, inokonzerwa nenzvimbo yakatsiga, inopenya.
3. Kumwe kuremara kwakadai sepamhepo pores uye kukwenya kunogona kuzadzwa nekupukuta, kuitira kuvandudza kupokana kuneta uye kuneta kupokana. Biphae Steel Flanges ane kakawanda kudarika simba rekubereka reAustenitic simbi, uye vane zvakaringana zvinodikanwa zvekuumbwa uku, kunyanya muCracture Kudzvinyirira, kunyanya muCloride nharaunda.
