I-UNS S32750 Duplex Stainless Steel

I-UNS S32750/F53/2507, evame ukubizwa ngokuthi i-Alloy 2507, iqukethe u-25% we-chromium kanye no-7% we-nickel ngaphezu kwephesenti elincane lethusi ukuze kuthuthukiswe ukumelana nokugqwala okujwayelekile. Leli banga le-super duplex linikeza amandla aphezulu kanye nokumelana okuhle kakhulu nokugqwala kwe-pitting kanye ne-crevice kanye ne-chloride stress corrosion cracking. Isetshenziswa kabanzi ekuhloleni/ukukhiqiza uwoyela, uwoyela negesi, kanye nokushintshanisa ukushisa ekucubunguleni i-petrochemical/chemical.

Izicelo

Ifaneleka ikakhulukazi ukusetshenziswa ezindaweni ezinolaka njengamanzi olwandle afudumele ane-chlorine

kanye nemidiya ene-acidic, ene-chloride. Isetshenziswa kabanzi ezindaweni zasolwandle, kanye ne-petrochemical/chemical processing.

Ukucutshungulwa kwamakhemikhali| Imishini yokukhiqiza i-Chloroethylene, i-methanol synthesis reactor, ezokuthutha i-acetic acid, nokugcinwa.

Amafutha negesi| Ukuhlola uwoyela negesi nokuhamba, imishini yokuqhekeka ye-Catalytic, imishini ye-hydrotreating.

I-alloy S32750 isetshenziswa kakhulu ezimbonini zikawoyela negesi, izimboni zasolwandle, ukucubungula amakhemikhali, nezimboni zenuzi ngenxa yamandla azo amahle kakhulu kanye nokumelana nokugqwala okuhle. I-LKALLOY ingumnikezeli ohamba phambili embonini we-S32750 namanye ama-alloys ensimbi engagqwali aphezulu. I-LKALLOY ihlinzeka ngepayipi lensimbi engagqwali i-S32750, ishubhu, ipuleti, nokufakwa kwepayipi esixazululweni esilashwe futhi esicishiwe. Imininingwane etholakalayo ye-S32550 yi-ASTM A240, ASTM A479 nokunye.
