Nyob rau hauv kev xav tau cov haujlwm uas zoo li offshore roj & roj av, thiab vim li cas nws tseem ceeb rau kev siv cov ntaub ntawv zoo tshaj plaws .
Nkag Siab ATM A182 F53
ASTM A182 yog lub hauv ntiaj teb lees paub cov qauv siv hluav taws xob sib xyaw, "yog hais txog cov khoom siv ntau tshaj plaws ntawm cov qauv kub siab Ib 182. Cov qib no yog cov qauv piav qhia los ntawm cov kev sib koom tes cov lej (unsication)32750.
ASTM A182 F53 Tshuaj Muaj Tshuaj
Dab tsi ua rau A182 F53 F53 yog dab tsi rau cov qhab nia zoo nkauj rau cov qauv Duplex)
- Chromium (CR):Nyob ib ncig ntawm 25% rau kev tshwj xeeb tsis kam rau ntau yam ntawm cov xov xwm corrosive, tshwj xeeb tshaj yog oxidizing cov acids thiab chloride ib puag ncig.
- Molybdenum (MO):Kwv yees li ntawm 4% rau kev ua kom zoo dua rau pitting thiab crevice corrosion, tseem ceeb hauv qab ntsev lossis acidic}}
- Nickel (NI):Txog 7% kom sib npaug ntawm microstructure, txhim kho kev nruj, thiab muab cov corrosion corrosion.
- Nitrogen (n):Ib qho tseem ceeb ntxiv (~ 0 {. 3%) uas ua kom muaj zog ntxiv (tshwj xeeb tshaj yog cov cim zog) thiab txhim kho pitting.
Qhov no tshwj xeeb ua ke tsim cov khoom siv ntau zog thiab nyuaj dua li cov qauv Austenitic stainless hlau tsis kam .
F53 Lub Zog Kho Tshuab
Super Duplex F53 Boasts Tshwj Xeeb Cov Zog Ntiav Reriving los ntawm nws muaj pes tsawg leeg thiab tswj tau tsim:
- High tawm tswv yim lub zog: Feem ntau ntau dua 550 MPa (80 ksi
- Siab tensile lub zog: feem ntau tshaj 750 mpa (110 ksi) .
- Zoo tougness thiab ductility: txawm muaj lub zog siab, nws khaws lub zog kom txaus (elongation ~ 25%) rau kev pabcuam xav tau.
- Siab tiv thaiv corrosion tawg: nws tus qauv duplex muab ntau dua ntau dua kev tiv thaiv nyob rau hauv ib puag ncig muaj chlorides piv rau austမ steel {}}
ASTM 182 F53 Corrosion Kuj
ASTM A182 F53 Ua tiav nws "Super Duplex" raws li kev ua haujlwm corrosion, ntsuas los ntawm kev tso cai tiv thaiv tus lej (pren).
- High PREN (>40+):F53 muaj tus kheej pren (pren =}} {} {{3} {{6} {{3} {{3} { Outperforming 316 (Pren ~ 25) thiab cov qauv duplex s32205 (pren ~ {{{{{{{{{{{{{{{{{{{{{{{{{{{{}}}
- Kuj muaj cov acids:Ua yeeb yam zoo nyob rau hauv diluteded reducing reducing reducing reducing reducing reducing reducing reducing reducing reducing pos}, chromic) thoob plaws ntau thiab kub {}}
F53 Forging rau flanges, fittings thiab li qub
Daim F53 tshwj xeeb tshwj xeeb siv rau cov khoom lag luam tsim los ntawm kev zam los ntawm kev zam los ntawm kev zam los ntawm forging. tus qauv A182 ua tiav li cas F53 cov khoom siv:
- Melting:Feem ntau ntawm hluav taws xob arc
- Forging:Cov khoom noj khoom noj kom huv yog cov cua sov thiab cov kab mob forgeting / diss} {} {.
- Kev Kho Cua Sov:Ib qho tseem ceeb, tsis yog txoj kev xav txog qhov kub thiab yooj yim. ua kom zoo nkauj microstructure thiab rov qab tag nrho corrosion .
- Kuaj thiab tshuaj xyuas:Kev Ntsuas nruj nruj ua raws li kev soj ntsuam tshuaj lom neeg (feem ntau} {} {1} {} phases .
ASTM A182 F53 Kev Siv
Qhov kev sib xyaw no ntawm lub zog, corrosion tsis kam, thiab tawv ua rau F53 indispensable rau cov chaw hnyav hauv ib puag ncig hnyav:
- Cov roj offshore thiab roj: cov ntoo uas muaj hnub qub, cov khoom siv Christmas, cov twj koob tshuaj Hwj Che.
- Cov Khoom Siv Tam Sim No: Kev Txuas Txuas Txuas Txuas Flanges, Fittings, Umbilical Termination .}}
- Tshuaj lom neeg thiab petrochemical: reactors, cov hlab ntsha, cov raj mis siab tuav tshuaj corrosive tshuaj .
- Kev nqis tes thiab dej hiav txwv
- Flue Gas Desulfurization (FGD): Absadber Ntauwd Internals Qhov chaw Chlorides thiab Acids tawm cov ntaub ntawv tsawg dua {}}
Siab-siab / siab-kub (HPHT) ntau lawm ib puag ncig.
Xaiv thiab qhia meej Astm A182 f53 kom raug yog qhov tseem ceeb:
- Ntawv pov thawj:Kev thov cov ntawv pov tseg zeb nrog ASTM A182 F {{{}}}}10204 3.1 hom ntawv pov thawj.
- Tau qhov twg los tau cov millutable mills:Cov complex uas nws yuav tsum tau ua rau cov txheej txheem siab tshaj . Xaiv cov neeg muaj kev tshaj lij hauv Super Duplex Raug {}}
- Fabrication kev txawj ntse:Vuam thiab machining F53 yuav tsum tau cov txheej txheem tshwj xeeb vim nws qhov kev paub txog cov txheej txheem cua sov thiab kev pheej hmoo ntawm cov txheej txheem sau tseg rau Super Duplex qeb.
- Tshuaj xyuas:Txheeb xyuas cov lus qhia kev ywj pheej rau cov khoom tseem ceeb xws li chemistry, tensile, cov qauv kev cuam tshuam tseem ceeb, thiab qauv micrographic {}}
Tag
Super Duplex ASTM A182 F53 (UNS S32750) is not just another stainless steel; it's a precisely engineered, high-performance alloy processed under rigorous standards specifically for forging. Its remarkable blend of extreme strength, outstanding corrosion resistance especially in chlorides (PREN >40), thiab kev ua tiav zoo heev, ua tiav los ntawm kev zam tau zoo tag nrho, thiab kev kho kom zoo nkauj, ua rau nws muaj kev xaiv thaum tshav ntuj
Thaum cov khoom sib sib zog nqus dej, acidic siv tshuaj, itt fittings kev ntseeg siab rau kev ua tiav hauv ntiaj teb cov kev nyuaj siab tshaj plaws hauv lub ntiaj teb feem ntau.}
