I-S32750 I-Stainless Steel Seamless Tubing
Isingeniso Somkhiqizo
I-Super Duplex engagqwali njenge-S32750, iyisakhiwo esincane esixubile se-austenite ne-ferrite (50/50) esithuthukise amandla ngaphezu kwamazinga ensimbi e-ferritic ne-austenitic. Umehluko omkhulu ukuthi i-Super Duplex inokuqukethwe okuphezulu kwe-molybdenum ne-chromium okunikeza izinto izinto ezinkulu. I-chromium ephezulu iphinde ikhuthaze ukwakheka kwezigaba ze-intermetallic eziyingozi, ezizwela ukuqhekeka okungu-475°C ngenxa yemvula yesigaba se-α' esicebile nge-chromium, kanye nokuqhekeka yi-sigma, i-chi nezinye izigaba emazingeni okushisa aphezulu.
I-Alloy 2507 (S32750) nayo inokuqukethwe okuphezulu kwe-nitrogen, okungagcini nje ngokukhuthaza ukwakheka kwe-austenite futhi kwandise amandla, kodwa futhi kubambezela ukwakheka kwezigaba ze-intermetallic ngokwanele ukuvumela ukucutshungulwa nokukhiqizwa kwebanga le-duplex.
Ibanga libonakala ngokumelana nokugqwala kwe-chloride okuhle kakhulu, kuhlanganiswe namandla aphezulu kakhulu omshini. Lifaneleka kakhulu ukusetshenziswa ezindaweni ezinolaka njengamanzi olwandle afudumele ane-chlorine kanye nemidiya equkethe i-chloride ene-acidic.
Izici ze-Alloy 2507 (S32750) zimi kanje:
● Ukumelana okuhle kakhulu nokuqhekeka kokugqwala kokucindezeleka (SCC) ezindaweni ezithwala i-chloride
● Ukumelana okuhle kakhulu nokugqwala kwemigodi kanye ne-crevice
● Ukumelana okuphezulu nokugqwala okuvamile
● Amandla aphezulu kakhulu omshini
● Izakhiwo ezibonakalayo ezinikeza izinzuzo zomklamo
● Ukumelana okukhulu nokugqwala nokukhathala kokugqwala
● Ukushintshwa okuhle
I-S32750 yenzelwe izinhlelo zokusebenza ezidinga amandla akhethekile kanye nokumelana nokugqwala, ezitholakala ku-inqubo yamakhemikhali, imishini yamakhemikhali kaphethiloli, kanye neyamanzi olwandle. Isetshenziswa kabanzi ekuhlolweni/ekukhiqizweni kukawoyela negesi ogwini lolwandle kanye nasezishintshisaneni zokushisa ekucutshungulweni kukaphethiloli/kwamakhemikhali. Leli banga lifanelekela futhi ukusetshenziswa kwe-hydraulic kanye nemishini ezindaweni zasolwandle ezishisayo.
