316/304 Duplex Stainless Steel:
Insimbi engagqwali i-Duplex iwuhlobo lwengxube yensimbi engagqwali ehlanganisa izinzuzo zazo zombili izinsimbi ezingenasici ze-austenitic ne-ferritic. Igama elithi "duplex" libonisa i-microstructure yesigaba esikabili ye-alloy, ehlanganisa kokubili i-austenitic (isakhiwo sekristalu eyi-cubic egxile ebusweni) kanye nezigaba ze-ferritic (i-cubic crystal structure) egxile emzimbeni. Le nhlanganisela eyingqayizivele yama-microstructures idlulisela isethi yezakhiwo ezenza insimbi engagqwali e-duplex ifaneleke ngokukhethekile izinhlelo zokusebenza ezifunwa kakhulu.
Ukwakhiwa:
Izinsimbi ezingenasici eziyi-Duplex ngokuvamile ziqukethe inani elibalulekile le-chromium (elisuka ku-19% ukuya ku-32%) kanye ne-nickel (cishe ama-5% kuya ku-8%), afana nezinsimbi ezingenasici ze-austenitic. Ukwengeza, anokuqukethwe okuphezulu kwe-molybdenum (kufika ku-5%) futhi ngezinye izikhathi nezinye izakhi ze-alloying njenge-nitrogen ne-manganese. Ukwakheka kwe-alloy ethile kuyahlukahluka kuye ngebanga le-duplex yensimbi engagqwali.
Izici Eziyinhloko:
Ukumelana Nokugqwala: I-Duplex insimbi engagqwali inikeza ukumelana nokugqwala okuhle kakhulu, ikakhulukazi ezindaweni ezinolaka njengezixazululo ezine-chloride. Lokhu kuyenza ifaneleke izicelo zokucubungula amakhemikhali, izindawo zasolwandle, nezimboni zikawoyela negesi.
Amandla Aphezulu: Insimbi engagqwali e-Duplex ibonisa amandla aphezulu uma iqhathaniswa nezinsimbi ezingenasici ze-austenitic neze-ferritic. Lawa mandla athuthukisiwe avumela ukusetshenziswa kwezingxenye ezincane ezingxenyeni zesakhiwo, okunomthelela ekwehliseni isisindo emisebenzini ehlukahlukene.
Ukuqina Okuhle kanye Ne-Ductility: Insimbi engagqwali ye-Duplex igcina ukuqina okuhle kanye ne-ductility ngisho nasezingeni eliphansi lokushisa, okunenzuzo ezinhlelweni zokusebenza lapho ukumelana komthelela kubalulekile.
I-Stress Corrosion Cracking Resistance: Insimbi engagqwali e-Duplex inokumelana kangcono nokucindezeleka kokuqhekeka kokugqwala kunezinsimbi ezingenasici ze-austenitic, ikakhulukazi ezindaweni ezicebile nge-chloride.
Ukushisela: Nakuba insimbi engagqwali eyi-duplex ingashiselwa kalula njengensimbi engagqwali ye-austenitic, amasu esimanje wokushisela kanye nezinqubo ezifanele zikwenza kube nokwenzeka ukuzuza ukushisela okuqinile nokuthembekile ezintweni eziyi-duplex.
Izicelo:
Ngenxa yenhlanganisela yayo eyingqayizivele yezakhiwo, insimbi engagqwali eyi-duplex isetshenziswa ezimbonini nasezintweni ezahlukahlukene, kufaka phakathi:
Ukucubungula Amakhemikhali: Izisetshenziswa ezifana nemikhumbi yokucindezela, amasistimu wamapayipi, nezishintshisi zokushisa ezimbonini ezicubungula amakhemikhali ziyazuza ekumelaneni nokugqwala namandla ensimbi engagqwali eyi-duplex.
Uwoyela Negesi: Insimbi engagqwali i-Duplex isetshenziswa ezindaweni ezingasogwini nezisogwini zikawoyela negesi kumapayipi, amavalvu, nezinye izinto ezichayeke endaweni egqwalayo.
Ukukhipha usawoti emanzini: Ukumelana nokugqwala kwensimbi engagqwali eyi-duplex kuyenza ifanelekele izitshalo zokukhipha usawoti emanzini lapho ichayeke khona emanzini olwandle.
Unjiniyela Wasolwandle: Izingxenye ezinjengama-propeller, shafts, nezixhumi ezindaweni zasolwandle zizuza ekumelaneni nokugqwala namandla ensimbi engagqwali eyi-duplex.
Izinhlelo zokusebenza zesakhiwo: I-Duplex insimbi engagqwali isetshenziswa ezingxenyeni zesakhiwo zokwakha nokwakha, ikakhulukazi ezindaweni ezinezinto ezigqwalayo.
Sengiphetha, insimbi engagqwali eyi-duplex iwumsebenzi oguquguqukayo ohlanganisa izici ezingcono kakhulu zazo zombili izinsimbi ezingenasici ze-austenitic kanye ne-ferritic. Izakhiwo zayo ezihlukile ziyenza ikhetheke kakhulu ezinhlelweni zokusebenza lapho ukumelana nokugqwala, amandla, nokuqina kuyizidingo ezibalulekile. Njengoba ubuchwepheshe buthuthuka, ukuthuthukiswa kwamabanga amasha ensimbi engagqwali eyi-duplex kuyaqhubeka nokwandisa uhla lwayo lwezinhlelo zokusebenza ezimbonini ezahlukahlukene.
