Nyob rau hauv siab -salinity thiab corrosive ib puag ncig, kev xaiv cov khoom siv yog txoj kab nyias ntawm kev ua haujlwm tau zoo thiab kev puas tsuaj loj.C68700 Aluminium Brass(UNS C68700) tau tshwm sim los ua tus qauv kev lag luam rau cov khoom siv hluav taws xob thiab cov khoom siv hauv hiav txwv, muab qhov sib npaug tshwj xeeb ntawm kev tiv thaiv corrosion thiab kev siv tshuab ua haujlwm ntev.
Phau ntawv qhia no muab kev tshaj lij kev ua haujlwm rau cov kws ua haujlwm thiab cov thawj coj saib xyuas kom ua kom zoo dua lawv cov khoom siv.
1. C68700 khoom yog dab tsi?
C68700 yog tooj liab-zinc- aluminium alloy engineered tshwj xeeb rau cov mob hnyav heev. Dab tsi ua rau nws sib nrug yog nws lub peev xwm los tsim ib qhonyias, tiv thaiv, tus kheej -kho zaj duab xisntawm nws qhov chaw thaum raug dej hiav txwv ntws.
Txuj kev ua raws caiKhoom siv: ASTM B111, ASME SB111.
Qhov tseem ceeb Advantage: Superior resistance to "impingement" (high -ceev yaig) piv rau tus qauv tooj dag.
2. Cov Lus Qhia Tshwj Xeeb: Tshuaj & Mechanical
C68700 tshuaj muaj pes tsawg leeg
| Element | Cov ntsiab lus (%) | Lub luag haujlwm hauv Alloy |
| Copper (Cu) | 76.0% - 79.0% | Base hlau, muab thermal conductivity. |
| Aluminium (Al) | 1.8% - 2.5% | Tseem ceeb:Tsim cov txheej tiv thaiv oxide. |
| Arsenic (As) | 0.02% - 0.06% | Kev tiv thaiv zoodezincification. |
| Zinc (Zn) | Tseem tshuav | Txhim khu lub zog thiab machinability. |
C68700 Mechanical Properties (Hom rau Tubes)
Tensile zog: 450 - 600 MPa
Yield zog: Ntau dua lossis sib npaug li 150 MPa
Elongation: Ntau dua lossis sib npaug li 35%
Thermal conductivity100 W / (m·K) ntawm 20 degree
3. Vim li cas cov neeg yuav khoom thoob ntiaj teb xaiv C68700?
A. Exceptional Biofouling & Corrosion Resistance
C68700 zoo li tiv thaiv dezincification vim nws cov ntsiab lus arsenic meej. Nws vam meej nyob rau hauv siab - nrawm nrawm dej thiab dej hiav txwv, ua rau nws nyiam lwm txoj hauv kev rau C44300 (Admiralty Brass) hauv ib puag ncig hnyav.
B. Tus nqi -Kev Ua Tau Zoo
Txawm tias kim dua li tus qauv tooj dag (kwv yees . 10-15% hwm),ASTM B111 C68700yog ho pheej yig duaTooj liab -Nickel (C70600)los yogTitanium alloys, muab ib qho "optimized nruab nrab hauv av" rau nruab nrab - mus rau - siab -end industrial projects.
C. Zoo heev Thaum tshav kub kub hloov Efficiency
Nws cov thermal conductivity yog qhov zoo tagnrho rau cov khoom siv hluav taws xob sib txawv, ua kom lub zog siab tshaj plaws hauv cov nroj tsuag desalination thiab cov chaw nres tsheb fais fab condensers.
4. Kev siv tseem ceeb hauv kev lag luam niaj hnub
- Marine Engineering: Condenser raj rau nkoj, offshore roj rig piping, thiab seawater txias tshuab.
- Lub zog tiam: Kub exchanger raj rau nuclear thiab fossil roj fais fab nroj tsuag.
- Desalination Nroj tsuag: Evaporator raj thiab distillation units.
- Roj & Roj: Cov khoom siv distillation thiab cov khoom siv hluav taws xob sib hloov hauv cov refineries.
5. Kev Qhia & Fabrication Guide
1. Kub tsim: Ua haujlwm zoo tshaj plaws ntawm 720℃thiab 800 degree.
2. Ua haujlwm txias: Cov txias txias zoo heev - cov khoom ua haujlwm (deformation tus nqi Tsawg dua lossis sib npaug li 60% qhia ua ntej annealing).
3. Vuam: TIG lossis Laser vuam raug pom zoo.Tswv yim Pro:Siv Argon shielding los tiv thaiv aluminium oxidation thaum vuam.
4. Kev kho deg: Tshuaj polishing lossis npib tsib xee plating tuaj yeem siv los txuas ntxiv kev pab cuam lub neej nyob rau hauv huab acidity.
6. Kev Tshawb Fawb Txog Kev Muag Khoom: Cov Khoom Muag Khoom & Cov Qauv
Tam sim no, kev lag luam xav tau C68700 tau nce siab hauv Asia -Pacific thiab Cov cheeb tsam Middle East vim muaj kev nqis peev loj hauv desalination thiab ntsuab zog.
Tus neeg yuav khoom ceeb toom:Thaum muab khoomASTM B111 C68700 Tubes, xyuas kom koj tus neeg muag khoom muab Eddy Current Testing (ECT) thiab Hydrostatic Testing reports. Ntawm Baohui Steel, peb tuav cov khoom lag luam ntse rau tus qauv qhov ntev (Sab nraud Dia 10-250mm), ua kom lub sijhawm ua haujlwm ruaj khov ntawm 15-25 hnub.
Cov ntsiab lus
C68700 Aluminium Brassyog ntau tshaj li hlau; nws yog "Green Corrosion-Resistant" kev daws teeb meem uas ua rau qhov sib txawv ntawm qis- tooj dag kawg thiab siab - nqi titanium. Nws ib puag ncig compatibility thiab kev ntseeg siab ua rau nws lub neej yav tom ntej ntawm marine thiab lub zog txias tshuab.
