ASTM A790 Super Duplex 2205 Tube & Tube Chaw tsim khoom, Hu rau peb kom tau txais cov npe nqe, Qhov ntau thiab tsawg & Cov qauv dawb!
Super duplex 2205 yeeb nkab yog qhov siab - cov yeeb nkab ua tau zoo ua los ntawm duplex stainless hlau 2205 (UNS S32205 / S31803). Nrog nws cov cim duplex microstructure thiab optimized tshuaj muaj pes tsawg leeg, nws yog dav siv nyob rau hauv hnyav ib puag ncig xws li petrochemicals, marine engineering, thiab cov khoom siv zog. HT PIPE is a2205 cevtus xa khoom nrog 15+ kev xa tawm.Tiv tauj pebkom paub ntau ntxiv thiab quotes dawb!
Technical Specifications: Super Duplex 2507 Khoom Khoom
Super Duplex 2507 nta qhov sib npaug nruj me ntsis 50/50 austenitic-ferritic grain matrix. Txhawm rau ntes cov kev tshawb fawb tshwj xeeb engineering, peb cov ntaub ntawv tau lees paub tag nrho raws li ob txoj cai tsim khoom tseem ceeb:
- ASTM A790 / ASME SB790 Cov Lus Qhia:Qhia hnyav-phab ntsa seamless thiab ncaj- seam welded kav rau siab -siab, corrosive heev workflows.
- ASTM A928 / ASME SB928 Cov Lus Qhia:Npog hluav taws xob -fusion-welded (EFW) duplex piping integrated nrog muab tub lim hlau rau loj - txoj kab uas hla.
Kev sib piv tshuaj lom neeg: Super Duplex 2507 vs. Standard 2205
Txhawm rau hais txog qhov kev txhim kho kev ua tau zoo rau pawg neeg yuav khoom, cov lus no qhia tau tias yog vim li cas Super Duplex 2507 muab kev txhim kho hauv cheeb tsam kev tiv thaiv corrosion tshaj tus qauv 2205.
| Lub ntsiab | Chromium (Cr) | Nickel (Ni) | Molybdenum (hli) | Nitrogen (N) | Copper (Cu) | PREN Tus nqi |
| Super Duplex 2507 | 24.0 - 26.0 | 6.0 - 8.0 | 3.0 - 5.0 | 0.24 - 0.32 | Tsawg dua los yog sib npaug li 0.50 | Ntau dua lossis sib npaug li 41 |
| Standard Duplex 2205 | 22.0 - 23.0 | 4.5 - 6.5 | 3.0 - 3.5 | 0.14 - 0.20 | - | 34 - 36 |
Txhim kho Mechanical Properties
Qhov hnyav alloying ntawm 1.4410 yeeb nkab khoom yields siab dua mechanical thresholds tshaj tus qauv austenitic steels, tso cai rau lub teeb yuag qauv piping tsim rau siab - siab installation.
- Tensile zog:Ntau dua lossis sib npaug li 800 MPa
- Yield zog (0.2% Offset):Ntau dua lossis sib npaug li 550 MPa
- Elongation:Ntau dua lossis sib npaug li 15%
Pitting thiab crevice corrosion kuj
PREN tus nqi (pitting kuj sib npaug) tshaj 35, zoo dua li 316L stainless hlau.
Kev nyuaj siab corrosion cracking (SCC) kuj
Kev ua tau zoo hauv cov tshuaj chloride- muaj ib puag ncig, haum rau cov dej hiav txwv, cov roj acidic thiab roj thiab lwm yam xov xwm.
Uniform corrosion
Tus nqi corrosion nyob rau hauv acidic media xws li dilute sulfuric acid thiab acetic acid yog qis dua li cov tsoos austenitic steel.
Daim ntawv thov ntawm 2205 Pipe
Offshore Roj & Gas Infrastructure
Muab tso rau hauv subsea piping networks, sib sib zog nqus- hiav txwv risers, platforms, manifold piping, thiab downhole ntau lawm kab tuav hnyav qaub crude kwj nrog siab H_2S thiab CO_2.
Desalination Plants & Seawater Systems
Qhov zoo tshaj plaws rau Seawater Reverse Osmosis (SWRO) siab - cov kab tsheb thauj mus los, lub zog rov qab los, thiab cov chaw ua haujlwm hauv ntug dej hiav txwv muaj qhov ua rau muaj siab tshaj - cov kua dej yaig.
Flue Gas Desulfurization (FGD)
Siv rau kev sib tsoo cov kav dej tuav cov kua qaub acidic gases thiab cov txheej txheem rov ua dej khib nyiab heev.
