Izinto Zensimbi Engagqwali Yasolwandle: 316L, 2205 kanye no-904L Uma kuqhathaniswa

Isingeniso

Izinto zensimbi engagqwali zasolwandlezikhethwa emanzini olwandle, isifutho sikasawoti, umoya wasogwini, imishini yolwandle, izibambo zasolwandle, amapayipi, amaphampu, amavalvu, imiphini kanye nezingxenye zesakhiwo. Insimbi engagqwali engu-316L iyona evame kakhulu emoyeni wasolwandle ojwayelekile kanye nokuchayeka okumaphakathi kwe-chloride. Insimbi engagqwali engu-2205 duplex inikeza amandla aphezulu kanye nokumelana okungcono kokucindezeleka nokugqwala kwe-chloride kune-316L. Insimbi engagqwali engu-904L inikeza ukumelana okuqinile kokugqwala ezindaweni ezine-acidic ne-chloride, kodwa ngokuvamile ibiza kakhulu futhi ayitholakali kakhulu kune-316L kanye ne-2205.

Kubathengi abaqhathanisayo316L, 2205 kanye ne-904L, izinto ezinhle kakhulu zincike ekugxilweni kwe-chloride, izinga lokushisa, isimo sokucwiliswa, ingozi yokuqhekeka, isidingo sokushisela, umthwalo wemishini, izinga lokuhlola kanye nesabelomali. Ama-316L angase anele ama-handrails, izihlanganisi zezakhiwo kanye nezingxenye zasolwandle ezivezwe kancane. I-2205 ivame ukuba ngcono kakhulu ezingxenyeni ezinomthwalo ophezulu, izakhiwo zasogwini, izinhlelo zamanzi olwandle kanye nemishini yokucindezela. I-904L ikhethwa lapho kudingeka khona ukumelana ne-asidi, okuqukethwe okuphezulu kwe-nickel kanye nokumelana okuthuthukisiwe kwemigodi, ikakhulukazi ezindaweni ezihlanganisiwe zamakhemikhali nasolwandle.

Ukuqhathaniswa Kwezindleko Nokutholakala

I-316L ivame ukuba yindlela engabizi kakhulu futhi etholakala kabanzi phakathi kwalezi ezintathu. Itholakala ngeshidi, ipuleti, ipayipi, ishubhu, ibha, ucingo, izinto zokubopha kanye nezinamathiseli ezitholakala kabanzi emhlabeni jikelele. I-2205 ivame ukubiza kakhulu ngekhilogramu, kodwa amandla ayo aphezulu anganciphisa isisindo sezinto ezisetshenziswayo ezingxenyeni eziklanywe ngobunjiniyela. I-904L ivame ukuba nezindleko eziphezulu kakhulu zezinto zokusetshenziswa ngenxa yokuqukethwe kwayo okuphezulu kwe-nickel kanye ne-molybdenum.

Abathengi kufanele baqhathanise izindleko zephrojekthi iyonke kunentengo ngekhilogramu kuphela. Izinga elibiza kakhulu linganciphisa ukulungiswa, ukushintshwa, isikhathi sokungasebenzi noma ukujiya kodonga. Kodwa-ke, ukucacisa ngokweqile i-904L ukuze kube nomoya opholile wasolwandle kungenza iphrojekthi ibize kakhulu ngokungadingekile.
