Raws li Senior Metal Products Manager ntawm peb cov chaw tsim khoom tshwj xeeb stainless hlau thiab npib tsib xee alloy, kuv saib xyuas kev tsim khoom ntawm kev ua haujlwm siab -Duplex Steel UNS S32750 Flanges. Cov khoom no xa lub zog, tiv thaiv corrosion, thiab kev cia siab rau qhov xav tau tshaj plaws hauv cov kav dej hauv cov roj & roj, petrochemical, chemical processing, desalination, thiab offshore platforms.
Dab tsi yog Duplex Steel UNS S32750?
UNS S32750 (Super Duplex 2507 / ASTM A182 F53) yog 25Cr-7Ni-4Mo-0.28N super duplex stainless hlau nrog sib npaug 50/50 austenite-ferrite microstructure. Cov khoom tseem ceeb muaj xws li:
PREN value >40 rau kev ua haujlwm zoo rau pitting thiab crevice corrosion
Zoo heev tiv thaiv chloride kev nyuaj siab corrosion cracking
Yield zog kwv yees li ob npaug ntawm cov qhab nia austenitic
Zoo weldability thiab toughness mus rau -50 degree
Duplex Steel UNS S32750 Flanges Manufacturing Specifications thiab Standards
Raws li cov khoom lag luam zoo tshaj plaws, peb ua raws li peb cov khoom lag luam nrog cov qauv nruj tshaj plaws thoob ntiaj teb. Txawm hais tias koj xav tau tus qauv - qhov loj me flanges lossis loj - txoj kab nruab nrab ntawm cov khoom, peb lub Hoobkas tau nruab rau xa.
1. ASME B16.5 Kev Ua Raws Cai (NPS 1/2 txog NPS 24)
Rau cov kav dej txheem, peb tsim S32750 flanges raws li ASME B16.5. Cov txheej txheem no suav nrog kev siab- qhov ntsuas kub, cov khoom siv, qhov ntev, qhov siab ntev, cim, thiab kev ntsuas.
Cov chav kawm siab: 150, 300, 400, 600, 900, 1500, thiab 2500.
Hom: Weld Neck (WN), Slip-On (SO), dig muag (BL), Threaded (TH), thiab qhov (socket Weld) (SW).
Lub ntsej muag hom: tsa ntsej muag (RF), Lub ntsej muag tiaj tus (FF), thiab lub nplhaib hom sib koom (RTJ).
2. ASME B16.47 Ua raws (NPS 26 txog NPS 60)
Rau qhov loj - nplai infrastructure, xws li cov hlab ntsha siab lossis cov kab sib kis loj, peb ua raws li ASME B16.47. Peb muab ob qho tib si:
Series A (MSS SP-44): Feem ntau thicker thiab hnyav dua, siv rau cov qauv tsim muaj zog dua.
Series B (API 605): Ntau qhov sib zog thiab sib zog dua, feem ntau nyiam rau kev hloov chaw ua haujlwm lossis chaw nyob -ib puag ncig.
Duplex Steel UNS S32750 Flange Manufacturing txheej txheem
Peb cov flanges yog tsim los ntawm kev tswj hwm, rov ua dua txheej txheem uas ua kom zoo ib yam:
Forging: Kub forging los ntawm cov ntawv pov thawj lossis cov ntawv pov thawj ntawm cov xovxwm hydraulic, ua raws li kev ua kom zoo rau cov qauv nplej.
Kev kho cua sov: Kev daws teeb meem annealing ntawm 1020-1100℃nrog cov dej nrawm nrawm los kho cov duplex microstructure thiab ua kom muaj zog corrosion.
Machining: CNC precision machining kom ua tau raws li qhov ntev ntawm qhov siab, du nto tiav (Ra Tsawg dua los yog sib npaug rau 3.2 µm ntawm lub ntsej muag gasket), thiab cov ntsia liaj qhov rooj yog - qhov sib dhos.
Tiav & Kos Npe: Beveling, tig ntsej muag (saib lub ntsej muag, ntiv nplhaib- hom sib koom, lossis lub ntsej muag tiaj tus), thiab stamping mus tas li nrog cov xov tooj cua sov, qib khoom, qhov loj me, chav kawm, thiab tus qauv.
Cov hom muaj xws li Weld Neck, Slip-On, Dig Muag, Socket Weld, Threaded, Lap Joint, thiab Orifice Flanges. Kev kho deg xws li pickling, passivation, lossis electropolishing yog muaj thaum thov.
Quality Assurance thiab Authenticity
Peb lub Hoobkas ua haujlwm ntawm lub hauv paus ntsiab lus ntawm pob tshab. Txhua qhov kev xa khoom ntawm UNS S32750 flanges yog nrog los ntawm Daim Ntawv Qhia Txog Cov Khoom Siv (MTR) raws li EN 10204 3.1 (lossis 3.2 raws li kev thov).
Peb cov txheej txheem kuaj sab hauv suav nrog:
Cov Khoom Siv Zoo (PMI): Txheeb xyuas cov tshuaj muaj pes tsawg leeg ua ntej thiab tom qab tsim khoom.
Kev Ntsuas Ultrasonic (UT): Los xyuas kom tsis muaj qhov tsis xws luag hauv lub cev forged.
Microstructure Analysis: txhawm rau txheeb xyuas qhov sib npaug ntawm theem thiab tsis muaj cov theem tsis zoo.
Corrosion Testing: ASTM G48 Method Ib qho kev kuaj xyuas kom paub tseeb pitting kuj.
Tus Thawj Saib Xyuas Kev Pom Zoo: "Hauv kev lag luam hlau, ' pheej yig dua' feem ntau txhais tau tias ' pheej hmoo.' Super Duplex flange uas tsis tau raug kho kom raug -annealed yog lub luag haujlwm. Peb ua qhov tseem ceeb rau lub voj voog thermal kom ntseeg tau tias peb cov neeg tau txais cov khoom lag luam uas muaj zog raws li nws muaj zog. "
Vim Li Cas Koom Tes Nrog Peb?
Raws li lub Hoobkas tshwj xeeb, peb muab ntau tshaj li cov khoom lag luam; peb muab kev koom tes hauv engineering. Peb cov kws tshaj lij hauv ASTM, ASME, BS, DIN, thiab GOST cov qauv tso cai rau peb muab cov haujlwm thoob ntiaj teb nrog ib qho kev lav phib xaub.
Kev txawj ntse: Ntau xyoo dhau los ntawm kev paub tshwj xeeb hauv siab -nickel thiab duplex alloys.
Kev sim nruj: Txhua lub flange raug kho raws li qhov tseem ceeb ntawm kev nyab xeeb.
Ntiaj teb no Logistics: Muaj peev xwm xa tawm kom ntseeg tau tias koj qhov project nyob ntawm lub sijhawm.
Lub durability ntawm koj cov kav dej yog ib qho kev xav txog qhov zoo ntawm nws cov khoom. Xaiv cov khoom uas muaj qhov siab tshaj plaws tawm los thiab tus neeg muag khoom uas muaj qhov siab tshaj plaws.
