I-S32750 Stainless Steel Seamless Tubing

Incazelo emfushane:

I-alloy 2507, enenombolo ye-UNS S32750, iyingxubevange yezigaba ezimbili esekelwe ohlelweni lwe-iron-chromium-nickel enesakhiwo esixubile esinezilinganiso ezilinganayo ze-austenite ne-ferrite. Ngenxa yebhalansi yesigaba esiyi-duplex, i-Alloy 2507 ibonisa ukumelana okuhle kakhulu nokugqwala okujwayelekile okufana nalokho kwezinsimbi ezingenasici ze-austenitic ezinezici ezifanayo ze-alloying. Ngaphandle kwalokho, inamandla aphakeme okuqina namandla esivuno kanye nokumelana okungcono kakhulu kwe-chloride SCC kunozakwabo be-austenitic ngenkathi igcina ukuqina komthelela ongcono kunozakwabo be-ferritic.

Isingeniso Somkhiqizo

I-Super Duplex engenasici njenge-S32750, iyisakhiwo esincane esixubile se-austenite ne-ferrite (50/50) esithuthukise amandla ngaphezu kwamabanga ensimbi ye-ferritic ne-austenitic. Umehluko omkhulu ukuthi i-Super Duplex inokuqukethwe okuphezulu kwe-molybdenum ne-chromium okunikeza okokusebenza okukhulu I-chromium Ephakeme iphinde ikhuthaze ukwakheka kwezigaba ezilimazayo ze-intermetallic, ezizwelayo ku-475°C embrittlement ngenxa yokuna kwesigaba se-α' esicebile nge-chromium, kanye ne-embrittlement nge-sigma, chi nezinye izigaba emazingeni okushisa aphezulu.

I-alloy 2507 (S32750) nayo inokuqukethwe okuphezulu kwe-nitrogen, okungakhuthazi nje kuphela ukwakheka kwe-austenite nokwandisa amandla, kodwa futhi kubambezele ukwakheka kwezigaba ze-intermetallic ngokwanele ukuze kuvunyelwe ukucutshungulwa nokwakhiwa kwebanga le-duplex.

Ibanga libonakala ngokumelana nokugqwala okuhle kwe-chloride, kuhlanganiswe namandla aphezulu kakhulu emishini. Ifaneleka kakhulu ukusetshenziswa ezindaweni ezinolaka njengamanzi olwandle ane-chlorine afudumele kanye nemidiya ene-acidic chloride.

I-alloy 2507 (S32750) izici zimi kanje:

● Ukumelana okuhle kakhulu ne-stress corrosion cracking (SCC) ezindaweni ezine-chloride
● Ukumelana okuhle kakhulu nokugqwala nokugqwala kwemifantu
● Ukumelana okuphezulu nokugqwala okuvamile
● Amandla emishini aphezulu kakhulu
● Izakhiwo ezibonakalayo ezinikeza izinzuzo zokuklama
● Ukumelana okuphezulu nokugqwala kokuguguleka nokukhathala kokugqwala
● Ukushisela okuhle

I-S32750 yakhelwe izinhlelo zokusebenza ezinzima ezidinga amandla akhethekile nokumelana nokugqwala, ezitholakala ku-inqubo yamakhemikhali, amakhemikhali e-petrochemical, namanzi olwandle. Isetshenziswa kabanzi ekuhloleni/ukukhiqiza uwoyela wasolwandle kanye nasekukhiqizeni nasekushintsheni ukushisa ekucubunguleni i-petrochemical/chemical. Ibanga futhi lilungele ukusetshenziswa kwe-hydraulic kanye nezinsimbi ezindaweni zasolwandle ezishisayo.
