Izinto ezibonakalayo ze-S32205
I-ASTM A240/A240M--01 Duplex insimbi engagqwali 2205 ingxubevange iyiduplex insimbi engagqwali eyakhiwe 22% chromium, 2.5% molybdenum kanye 4.5% nickel-nitrogen alloy.Inamandla aphezulu, ukuqina komthelela omuhle kanye nokumelana nokugqwala okuhle kwengcindezi yendawo yonke.Amandla okukhiqiza angu-2205 ensimbi engagqwali eyi-duplex angaphezu kokuphindwe kabili kwensimbi evamile ye-austenitic.Lesi sici sivumela abaklami ukuthi behlise isisindo lapho beklama imikhiqizo, okwenza le ngxube ithengeke kakhulu kuno-316 no-317L.Le alloy ifaneleka ikakhulukazi ukusetshenziswa ebangeni lokushisa elingu-50°F/+600°F.Kuzinhlelo zokusebenza ezingaphandle kwalolu banga lokushisa, le alloy nayo ingacatshangelwa, kodwa kunemikhawulo ethile, ikakhulukazi uma isetshenziselwa izakhiwo ezishiselwe.
Izinzuzo ze-S32205 Duplex Steel
1.Amandla esivuno angaphezu kokuphindwe kabili kwensimbi engagqwali ye-austenitic ejwayelekile, futhi inezidingo zokwakheka ezidingekayo.
Ipulasitiki eyanele.Ukuqina kodonga lwamathangi okugcina noma imikhumbi yokucindezela eyenziwe ngensimbi engagqwali eyi-duplex iphansi ngo-30-50% kunaleyo ye-austenite evame ukusetshenziswa, evumela ukwehlisa izindleko.
I-2.Inokumelana okuhle kakhulu nokucindezeleka kokuqhekeka kokugqwala.Ngisho nensimbi engagqwali eyi-duplex enokuqukethwe kwe-alloy ephansi kakhulu inokumelana okuphezulu nokucindezela kokuqhekeka kokugqwala kune-austenitic stainless steel, ikakhulukazi endaweni equkethe ama-ion e-chloride.I-stress corrosion inkinga evelele insimbi engagqwali ye-austenitic okunzima ukuyixazulula.
3.Ukumelana nokugqwala kwensimbi engagqwali eyi-2205 esetshenziswa kakhulu emithonjeni eminingi yezindaba ingcono kuneyensimbi engagqwali engu-316L austenitic ejwayelekile, kuyilapho i-super duplex insimbi engagqwali inokumelana nokugqwala okuphezulu kakhulu, futhi kweminye imidiya, njenge-acetic acid, i-formic acid Ingakwazi ngisho nokuthatha indawo yensimbi engagqwali ene-alloy austenitic, ngisho nama-alloys amelana nokugqwala.
4. Inokumelana nokugqwala okuhle kwendawo.Uma kuqhathaniswa nensimbi engagqwali ye-austenitic enokuqukethwe kwe-alloy okulingana, ukumelana kwayo nokugqwala nokukhathala ukumelana nokugqwala kungcono kunensimbi engagqwali ye-austenitic.
5. I-coefficient yokunwetshwa komugqa iphansi kunaleyo ye-austenitic stainless steel, eseduze naleyo ye-carbon steel.Ifanele ukuxhuma nge-carbon steel futhi inokubaluleka okubalulekile kobunjiniyela, njengokukhiqizwa kwamapuleti ahlanganisiwe noma ama-linings.
6. Kungakhathaliseki ukuthi ingaphansi komthwalo oguqukayo noma izimo zomthwalo omile, inamandla okumunca amandla aphezulu kunensimbi engagqwali ye-austenitic, enezinzuzo ezisobala zezingxenye zesakhiwo ukuze zibhekane nezingozi ezingazelelwe njengokushayisana, ukuqhuma, njll., futhi inenani elisebenzayo lohlelo lokusebenza.
I-S32205 Material Application Areas
Imikhumbi yokucindezela, amathangi okugcina ingcindezi ephezulu, amapayipi okucindezela okukhulu, ama-heat exchangers (imboni yokucubungula amakhemikhali).
1.Amapayipi kawoyela negesi, ukufakwa komshini wokushisa.
2.Isistimu yokuhlanza indle.
3.Izihlukanisi zemboni ye-Pulp nephepha, izitshalo zokuxubha, ukugcinwa kanye nezinhlelo zokwelapha.
4.Ama-Rotary shafts, ama-press rolls, ama-blades, ama-impeller, njll. endaweni enamandla amakhulu kanye ne-corrosion resistant.
Amabhokisi we-5.Cargo wemikhumbi noma amaloli
6.Imishini yokucubungula ukudla
