1. Kune nzira ina dzekupolisha dzebi-phasesimbi flange: manual, mechanical, chemical and electrochemical. The corrosion resistance and decoration of theflangeinogona kuvandudzwa nekukwenenzvera. Iyo iripo yemagetsi kupukuta mvura yesimbi isina tsvina ichiri kushandisa phosphoric acid uye chromic anhydride. Mukuita kukwenenzverwa uye kuchenesa, imwe chromium uye phosphorus zvichaburitswa mumvura ine tsvina, zvichikonzera kusvibiswa kune zvakatipoteredza.
2. Passivation film ichaumbwa pamusoro pe duplexsimbi flange, uye iyo oxide firimu ichatanga kupera. Nekuti iyo yepamusoro microstructure ye duplexsimbi flangehaina kuenderana, chikamu chidiki chepamusoro chepamusoro chinonyungudutswa, uye chiyero chekunyungudika chichava chakakwira kupfuura chechikamu checoncave. Kuparara uye kuumbwa kwe membrane inenge panguva imwe chete, asi mavheji avo akasiyana. Nekuda kweizvozvo, kushata kwepamusoro kwebi-phase simbi flange kunoderedzwa, zvichikonzera kutsetseka, kupenya.
3. Kumwe kukanganiswa kwepamusoro senge ma pores epamusoro uye scratches inogona kuzadzwa nekupenya, kuitira kuti uvandudze kuneta kuramba uye kuenderana nekushomeka kwemarara. Biphase simbi flanges ine kanopfuura kaviri simba regoho reaustenitic stainless simbi, uye ine plastiki yakakwana uye kusimba kunodiwa pakuumbwa uku, pamwe nekunyanya kushushikana kukoromoka kwekuputsika, kunyanya munzvimbo dzechloride.
