Uhlolojikelele lwe-Duplex 2507

I-Duplex 2507 iyinsimbi engagqwali eyi-super duplex eyenzelwe izinhlelo zokusebenza ezidinga amandla akhethekile nokumelana nokugqwala.I-alloy 2507 ine-chromium engu-25%, i-molybdenum engu-4%, ne-nickel engu-7%.Lokhu okuqukethwe okuphezulu kwe-molybdenum, i-chromium kanye ne-nitrogen kubangela ukumelana okuhle kakhulu ne-chloride pitting kanye nokuhlaselwa kokugqwala kwe-crevice kanye nesakhiwo se-duplex sinikeza i-2507 ukumelana okuyingqayizivele ekuqhekekeni kwe-chloride stress corrosion.

Ukusetshenziswa kwe-Duplex 2507 kufanele kukhawulelwe ezinhlelweni zokusebenza ezingaphansi kuka-600° F (316° C).Ukuchayeka okunwetshiwe kwezinga lokushisa kunganciphisa kokubili ukuqina nokumelana nokugqwala kwe-alloy 2507.

I-Duplex 2507 inezakhiwo ezinhle kakhulu zemishini.Imvamisa igeji ekhanyayo yento engu-2507 ingasetshenziswa ukuze kuzuzwe amandla okuklama afanayo we-nickel alloy ewugqinsi.Ukonga okuwumphumela wesisindo kunganciphisa kakhulu izindleko eziphelele zokwenziwa.

Ukumelana Nokugqwala

I-2507 Duplex imelana kakhulu nokugqwala okufanayo ngama-asidi ephilayo afana ne-formic ne-acetic acid.Iphinde imelane kakhulu nama-acids angaphili, ikakhulukazi uma iqukethe ama-chloride.Ingxubevange 2507 imelana kakhulu ne-carbide-intergranular corrosion ehlobene.Ngenxa yengxenye ye-ferritic yesakhiwo esiyi-duplex ye-alloy imelana kakhulu nokucindezeleka kokuqhekeka kokugqwala endaweni efudumele equkethe i-chloride.Ngokungezwa kwe-chromium, i-molybdenum ne-nitrogen ukugqwala kwasendaweni okufana ne-pitting kanye nokuhlasela kwemifantu kuyathuthukiswa.I-alloy 2507 inokumelana okuhle kakhulu kwe-pitting yendawo.

Yiziphi izici ze-Duplex 2507?

● Ukumelana okuphezulu ne-chloride stress corrosion cracking
● Amandla Aphakeme
● Ukumelana okuphezulu ne-chloride pitting kanye nokugqwala kwemifantu
● Ukumelana nokugqwala okuhle okuvamile
● Okuphakanyiselwe izinhlelo zokusebenza ezifika ku-600° F
● Izinga eliphansi lokunwetshwa kwe-thermal
● Inhlanganisela yezakhiwo ezinikezwe isakhiwo se-austenitic ne-ferritic
● Ukushisela okuhle nokusebenza kahle

I-Duplex 2507 isetshenziswa kuziphi izinhlelo zokusebenza?

● Izisetshenziswa Zokukhipha Usawoti Kasawoti
● Imikhumbi yengcindezi yenqubo yamakhemikhali, amapayipi kanye nezishintshisi zokushisa
● Izicelo Zasolwandle
● Izinsiza Zokukhuhla Igesi Yokushibilika
● Isisetshenziswa Sokugaya Nephepha
● Ukukhiqizwa Kwawoyela Ngasolwandle/ubuchwepheshe
●Imishini yemboni kawoyela negesi
