2205 Ipuleti lensimbi yensimbi engagqwali Duplex
Incazelo
Ukumelana nokugqwala kwengcindezi kwe-2205 (00Cr22Ni5Mo3N) insimbi engagqwali eyi-duplex kusisombululo se-chloride engathathi hlangothi kanye ne-H2S kungcono kunaleyo ye-304L, 316L i-austenitic stainless steel kanye ne-18-5Mo duplex steel stainless.Kungaba okubandayo, ukucubungula nokwakhiwa okushisayo, ukushisela okuhle, insimbi ifaneleka izinto zokwakha, okwamanje isemhlabeni ensimbi engagqwali yesigaba esikabili esetshenziswa ebangeni elivame kakhulu.
2205 insimbi engagqwali plate(00Cr22Ni5Mo3N) duplex insimbi engagqwali yenziwe 21% chromium, 2.5% molybdenum kanye 4.5% nickel-nitrogen alloy.Inamandla aphezulu, ukuqina komthelela omuhle kanye nokuhlanganisa okuhle kanye nokumelana nokugqwala kwengcindezi yendawo.Amandla okukhiqiza we-2205 duplex stainless steel aphindwe kabili kunawe-austenitic stainless steel.Lesi sakhiwo sivumela abaklami ukuthi banciphise isisindo lapho beklama imikhiqizo, okwenza le ngxube ithengeke kakhulu kune-316,317L.Le alloy ifaneleka ikakhulukazi ukusetshenziswa ebangeni lokushisa elingu-50°F/+600°F.Izicelo ezingaphezu kwalolu banga lokushisa zingase futhi zicabangele le alloy, kodwa kunemikhawulo ethile, ikakhulukazi uma isetshenziswa ezakhiweni ezishiselwe.
2205 (00Cr22Ni5Mo3N) Izici Zensimbi Engenasici
1. Uma kuqhathaniswa ne-316L ne-317L insimbi engagqwali ye-austenitic, i-alloy engu-2205 inokusebenza okungcono ekumelaneni nokugqwala kanye ne-crack corrosion, inokumelana nokugqwala okuphezulu, uma kuqhathaniswa ne-austenite, i-coefficient yayo yokwandisa okushisayo iphansi, i-conductivity ephakeme yokushisa.
2. Uma kuqhathaniswa ne-austenitic stainless steel, amandla acindezelayo e-duplex 2205 steel stainless plate aphindwe kabili kunawe-austenitic stainless steel.Uma kuqhathaniswa ne-316L ne-317L, umklami anganciphisa isisindo sayo.Ingxubevange engu-2205 ifaneleka ngokukhethekile ukusetshenziswa ebangeni lokushisa elingu-50°F/+600°F ngisho namazinga okushisa aphansi ngaphansi kwemikhawulo eqinile (ikakhulukazi ezakhiweni ezishiselwe).
2205 (00Cr22Ni5Mo3N) Ukumelana Nokugqwala
1. Ukugqwala okufanayo
Ngenxa yokuqukethwe kwe-chromium (22%), okuqukethwe kwe-molybdenum (3%) kanye nokuqukethwe kwe-nitrogen (0.18%), ukumelana nokugqwala kuka-2205 kungaphezu kuka-316L no-317L ezindaweni eziningi.
2. Ukumelana nokugqwala kwendawo
Okuqukethwe kwe-chromium, i-molybdenum ne-nitrogen kunsimbi yesigaba esikabili engu-2205 kuyenza imelane kakhulu nokugqwala nokugqwala kwegebe ezixazululweni ze-oxidizing ne-asidi.
3. Ukumelana nokugqwala kwengcindezi
I-duplex microstructure yensimbi engagqwali iyasiza ukuthuthukisa ukumelana nokuqhekeka kwensimbi engagqwali.I-Chloride stress corrosion kwenzeka ensimbini ye-austenitic engagqwali ezingeni elithile lokushisa, ukushuba, umoya-mpilo kanye nokuba khona kwe-chloride.Ngenxa yokuthi lezi zimo kunzima ukuzilawula, ukusetshenziswa kwe-304L, 316L kanye ne-317L kunqunyelwe kulokhu.
4. Ukukhathala okuqeda ukugqwala
Amandla aphezulu kanye nokumelana nokugqwala kwe-duplex steel 2205 kuyenza ibe namandla okukhathala okuphezulu.Imishini yokucubungula isengozini ezindaweni ezigqwalile kanye nemijikelezo yokulayisha, futhi izici ze-2205 zilungele izinhlelo ezinjalo.
2205 (00Cr22Ni5Mo3N) Ukusetshenziswa
· Imikhumbi yokucindezela, amathangi okugcina umfutho ophezulu, amapayipi omfutho ophezulu, izishintshisi zokushisa (imboni yokucubungula amakhemikhali).
· Ukufakwa kwamapayipi kawoyela negesi kanye nezishintshisi zokushisa.
· Uhlelo lokuhlanza indle.
· Izigaba zemboni ye-Pulp nephepha, okokusebenza kokuxubha, ukugcinwa kanye nezinhlelo zokwelapha.
· Amashafu azungezayo, amarola okucindezela, ama-blades, ama-impeller, njll. endaweni ekwazi ukumelana nokugqwala okunamandla.
· I-Cargo container yomkhumbi noma iloli
· Imishini yokucubungula ukudla
