FAQ
Q1: Qhov txawv ntawm C70600 CuNi 90/10 thiab C71500 CuNi 70/30 yog dab tsi?
A:C70600 muaj 90% tooj liab thiab 10% npib tsib xee, thaum C71500 muaj 70% tooj liab thiab 30% npib tsib xee. C70600 muaj thermal conductivity ntau dua (40 W / m·K vs 29 W / m·K) thiab tsis tshua kim. C71500 muaj zog dua thiab ua haujlwm zoo dua rau siab -ceev seawater thiab sulfide nres. Rau feem ntau cov ntawv thov marine, C70600 txaus. Rau cov mob hnyav heev lossis kub siab dua, C71500 nyiam dua.
Q2: Dab tsi yog cov ntsiab lus hlau hauv C70600 condenser raj thiab vim li cas nws tseem ceeb?
A:C70600 muaj 1.0-1.8% hlau. Hlau yog qhov tseem ceeb vim tias nws txhim kho kev tiv thaiv kev tawm tsam (kev yaig-corrosion) nyob rau hauv siab - dej hiav txwv ceev. Cov hlau hloov kho cov yeeb yaj kiab tiv thaiv oxide ntawm lub raj nplaim, ua rau nws ua tau zoo dua thiab tiv taus cov tshuab tshem tawm. Yog tsis muaj hlau txaus, lub raj yuav erode sai sai hauv dej hiav txwv turbulent. Qhov no yog vim li cas C70600 qee zaum hu ua "90/10 tooj liab-nickel nrog hlau."
Q3: Dab tsi yog cov ntawv thov rau ASTM B111 C70600 raj?
A:C70600 raj yog siv rau saum npoo condensers nyob rau hauv lub hwj chim nroj tsuag, evaporators thiab tshav kub exchangers nyob rau hauv desalination nroj tsuag, shipboard txias tshuab, marine cav txias, thiab petrochemical tshav kub exchangers. Lawv yog cov tshwj xeeb tshaj yog nyob rau hauv seawater-txias tshuab qhov twg corrosion kuj thiab biofouling kuj yuav tsum tau. Lub alloy lub ntuj tsis kam mus rau marine kab mob txuas nrog txo tus nqi kho.
Q4: Dab tsi yog qhov txawv ntawm O61 thiab H55 temper rau C70600 raj?
A:O61 yog tag nrho annealed (mos), nrog qis zog (40 ksi tensile) tab sis siab ductility. H55 yog lub teeb-kos (ua haujlwm txias me ntsis), muaj zog dua (45 ksi tensile) tab sis qis dua ductility. O61 yog siv thaum lub raj yuav dov thiab nthuav mus rau hauv cov ntawv raj. H55 yog siv thaum xav tau lub zog siab dua los tiv thaiv lub siab los yog sab nraud loads. Feem ntau cov condenser raj tau muab rau hauv O61 temper.
Q5: Puas yog C70600 resistant rau biofouling (kev loj hlob marine)?
A:Yog lawm, C70600 muaj kev tiv thaiv zoo heev rau biofouling. Cov tooj liab ions tso tawm los ntawm lub raj nto yog lom rau cov kab mob hauv hiav txwv zoo li barnacles, mussels, thiab algae. Qhov no txo qhov kev xav tau ntawm kev tu thiab tswj kev hloov hluav taws xob. Tsis zoo li cov hlau tsis muaj steel lossis titanium, uas tuaj yeem txhim kho cov txheej txheem biofouling hnyav, C70600 cov hlab ntsha nyob twj ywm huv si hauv dej hiav txwv.
Q6: Dab tsi yog qhov sib npaug thoob ntiaj teb ntawm UNS C70600?
A:C70600 sib npaug suav nrog: Suav GB BFe10-1-1; British BS CN102; German DIN CuNi10Fe1.6Mn (2.1972); European EN CuNi10Fe1Mn (CW352H); Japanese JIS C7060. Txhua tus muaj qhov sib xws (9-11% Ni, 1.0-1.8% Fe, tshuav Cu). Nco ntsoov xyuas cov chemistry tshwj xeeb vim tias cov hlau thiab manganese sib txawv me ntsis los ntawm tus qauv.
Q7: Cov raj C70600 puas tuaj yeem siv rau hauv cov dej qias neeg lossis dej hiav txwv?
A:Yog, tab sis nrog ceev faj. C70600 ua tau zoo hauv cov dej hiav txwv huv. Hauv cov dej hiav txwv uas muaj kuab paug los yog nyob ruaj khov uas muaj cov sulfides (los ntawm cov organic lwj), C70600 tuaj yeem tsim cov yeeb yaj kiab dub sulfide uas tuaj yeem tawg tawm, ua rau muaj kev xeb sai. Rau cov xwm txheej zoo li no, C71500 (70/30) tiv taus ntau dua. Yog tias C70600 yuav tsum tau siv rau hauv cov dej qias neeg, ua kom nrawm nrawm dua 3 ft / s kom tsis txhob muaj qhov tsis zoo.
Q8: Dab tsi yog qhov siab tshaj plaws seawater tshaj tawm rau C70600 condenser raj?
A:C70600 cov raj feem ntau tuaj yeem zam cov dej hiav txwv nrawm txog 10-12 ko taw ib ob (3.0-3.7 m / s) yam tsis muaj qhov cuam tshuam loj heev. Qhov no zoo dua li txhuas tooj dag (8-10 ft / s) tab sis tsawg dua C71500 (12-15 ft / s). Rau qhov nrawm tshaj 12 ft / s, C71500 lossis titanium yuav tsum raug txiav txim siab. Qhov tseeb tso cai tshaj tawm yog nyob ntawm cov dej zoo, raj geometry, thiab cov chaw tsim khoom pom zoo.
Q9: Yuav tsum kuaj dab tsi rau ASTM B111 C70600 raj?
A:ASTM B111 yuav tsum tau: chemical tsom xam (Cu, Ni, Fe, Mn, Pb, Zn), tensile test (lub zog thiab elongation), expansion test (ductility for tube rolling), flattening test, grain size test (ASTM E112), eddy current or hydrostatic test for leaks, and dimensional inspection. Kev ntsuam xyuas kev ntxhov siab seem yog xaiv tau. GNEE muab cov ntawv qhia txog kev xeem ntawv pov thawj txhua qhov kev xeem uas xav tau.
Q10: Dab tsi yog qhov thermal conductivity ntawm C70600 piv rau lwm cov ntaub ntawv?
| Khoom siv | Thermal conductivity (W / m · K) |
|---|---|
| C70600 (90/10 CuNi) | ~40 |
| C71500 (70/30 CuNi) | ~29 |
| C68700 (Aluminium Brass) | ~100 |
| Titanium (Qib 2) | ~17 |
| 316 Stainless hlau | ~15 |
Q11: C70600 cov raj puas tuaj yeem welded lossis brazed?
A:C70600 tuaj yeem welded siv cov pa roj tungsten arc vuam (GTAW / TIG) nrog cov hlau sib txuam (ERCuNi). Brazing nrog nyiaj -raws li cov hlau tseem ua tau. Rau raj-rau-tubesheet pob qij txha hauv cov khoom siv hluav taws xob, dov thiab nthuav dav yog cov qauv txheej txheem, feem ntau ua raws li kev sib khi. Preheating (200-300℃F) yog pom zoo rau vuam. Kev kho cua sov tom qab tsis tas yuav tsum tau ua raws li C70600 tsis raug rau kev ntxhov siab corrosion tawg.
Q12: Vim li cas C70600 muaj xim lavender / ntshav?
A:Cov mos mos lavender lossis lub teeb liab doog hlau luster ntawm C70600 yog tus yam ntxwv ntawm tooj liab-nickel alloys. Cov xim los ntawm kev sib xyaw ntawm tooj liab liab thiab npib tsib xee silvery -zoo li dawb. Raws li cov ntsiab lus npib tsib xee nce, cov xim ua kom dawb (C71500 nrog 30% Ni yog yuav luag dawb). Cov xim txawv no pab txheeb xyuas C70600 hauv daim teb thiab qee zaum vim li cas nws hu ua "dawb tooj liab" hauv qee thaj tsam.
