Isingeniso
Uma uqhathanisaIbha Yensimbi Engagqwali Ephindwe Kabili engu-2205 vs 316L, abathengi kufanele bakhethe ibha yensimbi engagqwali engu-2205 lapho kudingeka amandla aphezulu, ukumelana nokugqwala kokucindezeleka kwe-chloride okungcono, ukumelana okuthuthukisiwe kokufaka imigodi kanye nokuphila isikhathi eside kwenkonzo kuyadingeka ezisetshenziswa zasolwandle, amakhemikhali, uwoyela negesi, ukukhishwa kukasawoti emanzini, ukusetshenziswa kwe-pulp kanye nephepha noma imishini yokucindezela. Khetha ibha yensimbi engagqwali engu-316L lapho indawo ingenalo ulaka kakhulu, ukushisela kanye nokukhiqiza kulula, ukulawula izindleko kubalulekile, futhi ukumelana nokugqwala kwensimbi engagqwali okujwayelekile kwe-austenitic kwanele. Ngamagama alula, i-2205 iyisinqumo esingcono se-chloride efunwayo kanye nezicelo ezinamandla aphezulu, kuyilapho i-316L iyisinqumo esingabizi kakhulu futhi esitholakala kabanzi sesevisi evamile yokulwa nokugqwala.
Ibha yensimbi engagqwali engu-2205 kanye nebha yensimbi engagqwali engu-316L zombili zisetshenziswa kabanzi ekushicileleni kwezimboni, emigodini, ezintanjeni, ezintanjeni, ezingxeni zamavalvu, ezingxeni zephampu, emishinini yasolwandle kanye nasemishinini yamakhemikhali. Kodwa-ke, izakhiwo zazo zensimbi zihlukile. I-316L iyinsimbi engagqwali e-austenitic enokuqukethwe okuphansi kwekhabhoni, kanti i-2205 iyinsimbi engagqwali e-duplex enesakhiwo esixubile se-austenite-ferrite. Lesi sakhiwo se-duplex sinikeza i-2205 amandla aphezulu okukhiqiza kanye nokumelana okungcono nokuqhekeka kokugqwala kwe-chloride stress kune-316L.
Ukuze kuthengwe, abathengi kufanele baqhathanise amandla, ukumelana nokugqwala, ukumelana nomgodi, ukuchayeka kwe-chloride, isidingo sokushisela, ubunzima bomshini, indinganiso yomkhiqizo, ukulawulwa kwenombolo yokushisa, i-EN 10204 3.1 MTC, ukuhlolwa kwe-PMI, ukuhlolwa kwe-UT, ibhalansi ye-ferrite uma kudingeka, ukuqeda ubuso, ukupakisha kokuthumela ngaphandle kanye nezindleko zephrojekthi eziphelele ngaphambi kokukhetha ibha yensimbi engagqwali engu-2205 noma engu-316L.
Iyini i-2205 Duplex Stainless Steel Bar kanye ne-316L?
Ibha yensimbi engagqwali ye-2205 duplex, evame ukubizwa ngokuthi i-UNS S32205 noma i-UNS S31803, iyinsimbi engagqwali ye-duplex ethuthukisiwe yi-nitrogen equkethe i-chromium, i-nickel kanye ne-molybdenum. Yenzelwe ukuhlinzeka ngamandla aphezulu kanye nokumelana nokugqwala okuqinile ezindaweni eziqukethe i-chloride. Ibha yensimbi engagqwali ye-2205 ivame ukucutshungulwa ibe yizicucu, amabhawodi, amantongomane, izingxenye zamavalvu, izingxenye zephampu, ama-coupling, ama-fasteners kanye nezingxenye zesakhiwo ezisetshenziswa enkonzweni enzima yezimboni.
Ibha yensimbi engagqwali engu-316L, evame ukubizwa ngokuthi i-UNS S31603, iyinsimbi engagqwali e-austenitic enekhabhoni ephansi equkethe i-chromium, i-nickel kanye ne-molybdenum. Inikeza ukumelana okuhle kokugqwala, ukushibilika okuhle kakhulu kanye nokutholakala okubanzi. I-316L isetshenziswa kabanzi emishinini yokudla, emishinini yamakhemikhali, emishinini yasolwandle, ezingxenyeni zezokwelapha, ezingxenyeni zokwakha, emigodini, ezindongeni nasezintweni ezenziwe ngomshini ezisetshenziswa kabanzi.

Imibuzo Evame Ukubuzwa Mayelana ne-2205 Duplex Stainless Steel Bar vs 316L
1. Yikuphi okungcono, i-duplex stainless steel bar engu-2205 noma i-316L?
Akukho lutho olungcono kakhulu emhlabeni wonke. I-2205 ingcono kakhulu ngenxa yamandla aphezulu, ukumelana nokugqwala kwe-chloride kanye nokumelana nokuqhekeka kokugqwala kokucindezeleka. I-316L ingcono ngenxa yesevisi yokugqwala evamile, ukwenziwa okulula, ukutholakala kabanzi kanye nezindleko eziphansi lapho kungekho ukuchayeka okukhulu kwe-chloride.
2. Ingabe i-2205 inamandla kune-316L?
Yebo. Ibha yensimbi engagqwali ye-2205 duplex ngokuvamile inamandla aphezulu okukhiqiza kune-316L. Lokhu kuyenza ifaneleke kuma-shaft, ama-fasteners, izingxenye zephampu, izingxenye zamavalvu kanye nezingxenye ezithwala umthwalo lapho amandla ebaluleke khona.
3. Yikuphi okune-resistance engcono yokugqwala?
I-2205 ngokuvamile inokumelana okungcono nokuqhekeka kokugqwala kwemigodi, ukugqwala kwe-crevice kanye nokucindezeleka kwe-chloride kune-316L. Kodwa-ke, ezindaweni ezimaphakathi, i-316L ingaba yanele futhi iyonga kakhulu. Ngenkonzo enzima kakhulu, ama-super duplex 2507 noma ama-nickel alloys angacatshangelwa.
4. Ingabe i-2205 ibiza kakhulu kune-316L?
Ezimweni eziningi, i-2205 ibiza ngaphezu kuka-316L ngenxa yokuqukethwe kwe-alloy, ukulawula ukukhiqizwa kanye nezinga lokusebenza. Kodwa-ke, inganciphisa izindleko zomjikelezo wokuphila ezindaweni ezinzima ze-chloride ngoba inganikeza impilo yesevisi ende kanye namandla aphezulu omshini.
5. Ingabe insimbi engagqwali engu-2205 ingashintshwa?
Yebo, i-2205 ingashiselwa, kodwa ukushiselwa kwe-duplex kudinga ukulawulwa okufanele kokufakwa kokushisa, ukukhethwa kokugcwalisa kanye nokuphathwa kwebhalansi ye-ferrite/austenite. I-316L ngokuvamile kulula ukuyishisela, kodwa i-2205 iyathandwa lapho kudingeka amandla aphezulu kanye nokumelana ne-chloride.
6. Abathengi bangaqinisekisa kanjani ukuthi impahla ingu-2205 noma u-316L?
Abathengi kufanele bahlole i-EN 10204 3.1 MTC, inombolo yokushisa, inombolo ye-UNS, ukwakheka kwamakhemikhali kanye nokumaka komkhiqizo. Ukuhlolwa kwe-PMI kunconywa kakhulu ngoba kungaqinisekisa okuqukethwe kwe-chromium, i-nickel kanye ne-molybdenum futhi kusize ekuboneni izinga elifanele lensimbi engagqwali.
7. Yiluphi ulwazi oludingekayo ukuze uthole ikhotheshini esheshayo?
Umbuzo ophelele kufanele ufake ibanga, inombolo ye-UNS, okujwayelekile, ububanzi, ubude, ubuningi, ukuqeda ubuso, ukubekezelelana, isidingo sokuhlola, isidingo se-MTC, imbobo yokuya kanye nesidingo sokupakisha. Isibonelo: Ibha eyindilinga yensimbi engagqwali ye-ASTM A276 UNS S32205 2205 ephindwe kabili, ububanzi obungu-35 mm, ubude obungu-3000 mm, ubuso obuhlutshiwe, ukuhlolwa kwe-EN 10204 3.1 MTC kanye ne-PMI.
Isiphetho
I-2205 Duplex Stainless Steel Bar kanye ne-316L Stainless Steel Bar zombili ziyizinto ezibalulekile ezingagqwali ezingagqwali, kodwa zikhethelwe izimo ezahlukene zesevisi. I-316L ifanele izingxenye ezijwayelekile ezingagqwali, imishini yokudla neyemithi, izingxenye ezijwayelekile ezenziwe ngomshini kanye nezinhlelo zokusebenza ezibucayi. I-2205 ifanele izingxenye ezinamandla aphezulu, izindawo ze-chloride, imishini yasolwandle, izinhlelo zokususa usawoti emanzini, izinhlelo zikawoyela negesi kanye nezingxenye ezidinga ukumelana okungcono nokuqhekeka kokugqwala kokucindezeleka.
Ukuze kuthengwe ngempumelelo, abathengi kufanele baqinisekise ibanga, inombolo ye-UNS, i-ASTM noma i-EN ejwayelekile, usayizi webha, ukubekezelelana, ukuqeda ubuso, i-EN 10204 3.1 MTC, ukulawula inombolo yokushisa, ukuhlolwa kwe-PMI, ukuhlolwa kwe-UT, ukuhlolwa kobukhulu kanye nokupakishwa kokuthumela ngaphandle. Umhlinzeki wensimbi engagqwali ochwepheshe kufanele asize abathengi baqhathanise ukumelana nokugqwala, amandla kanye nezindleko ngaphambi kokukhetha ibha yensimbi engagqwali engu-2205 duplex noma ibha yensimbi engagqwali engu-316L.
