Stainless simbi pombi imhando yegomba refu cylindrical simbi.Kukura kwayo kwekushandisa kunoshandiswa sepombi yekufambisa mvura.Inonyanya kushandiswa mumaindasitiri ekufambisa mapaipi akadai se petroleum, indasitiri yemakemikari, kurapwa, chikafu, chiedza indasitiri, michina zviridzwa uye mechaniki zvimiro zvemukati.Mapaipi esimbi asina simbi anogadzirwa nesimbi mabhiliti easidhi uye anodzivirira kupisa mamakisi kuburikidza nekudziya, perforation, saizi, inopisa kukunguruka uye kucheka.Muchokwadi, hapana chigadzirwa chinogona kudzivirirwa kubva mukuora kunze kwekunge chiri mune zvimwe zviitiko zvakakomba.Kana ndiro yedu yesimbi isina tsvina yakasvibiswa, inogona kukanganisa kushandiswa kwayo kwakajairika.Naizvozvo, tichiri kuda kutora matanho ekudzivirira kudzivirira mamiriro ezvinhu aya.Zvino ngatitangei kunzwisisa zvinhu zvinokonzeresa ngura yesimbi isina tsvina?
(1) Electrochemical corrosion:The scratch kunokonzerwa nekubatana pakati Stainless simbi ndiro uye kabhoni simbi zvikamu, uye ipapo kuumba galvanic sero ine corrosive medium, izvo zvinogadzira electrochemical ngura.Kana iyo pickling passivation effect isiri yakanaka, iyo passivation firimu iri pamusoro peplate ichave isina kuenzana kana yakaonda zvakanyanya, iyo iri nyore zvakare kugadzira electrochemical corrosion, slag cutting, splash uye zvimwe ngura zvinonamira zvinhu zvakabatanidzwa mundiro, uye wobva wagadzira galvanic cell ine corrosive medium, zvichiita kuti electrochemical corrosion.Pickling uye passivation kuchenesa haina kuchena, zvichiita kuti kemikari ngura zvigadzirwa pakati asara pickling uye passivation zvisaririra uye ndiro, uye ipapo electrochemical ngura pamwe ndiro.
(2) Mumamiriro ezvinhu akati, tsvina yakawanda yakakora, guruva, asidhi, alkali, munyu, nezvimwewo zvakanamatirwa pamusoro pemahwendefa esimbi isina tsvina zvichashandurwa kuva zvinopisa media, izvo zvinozoita kemikari nezvimwe zvikamu mumahwendefa, zvichiita kuti kemikemike iparadze uye ngura.Kuchenesa, pickling uye passivation hazvina kuchena zvakakwana, zvichiita kuti kucheneswa kwemvura yakasara, iyo inosvibisa ndiro.Iyo pamusoro peplate inoputika, iyo inotungamirira kuparadzwa kwefirimu yepasi, saka kukwanisa kwekudzivirira kweplate kunoderedzwa, uye zviri nyore kuita nemakemikari media.
