Dab tsi yog T2 Ntshav Copper Tube yog
T2 ntshav tooj liab raj yog seamless, tsis yog -ferrous hlau raj tsim los ntawm nias thiab kos duab. Cov xim uas muab cov khoom nws lub npe yog los ntawm cov ntshav liab - liab ntxoov ntxoo ntawm siab - purity tooj liab, thiab T2 lub npe yog Suav GB / T 5231 qib rau tooj liab nrog tooj liab ntxiv rau cov ntsiab lus ntawm tsawg kawg yog 99.90%. Lub npe American sib raug yog UNS C11000 electrolytic tawv pitch tooj liab, thiab Japanese sib npaug yog C1100. Cov alloy muaj cov hluav taws xob siab thiab thermal conductivity ua ke nrog zoo ductility thiab formability, yog li nws tuaj yeem khoov, flared, nthuav dav thiab koom nrog los ntawm kev sib tsoo lossis brazing. Nws yog dav siv nyob rau hauv cov cua txias thiab tub yees circuits, kub thiab txias dej mov kab, tshuaj txheej txheem pipework, txhua yam khoom siv thiab fabricated khoom.
Chemical Composition thiab Oxygen Control
Cov lus hauv qab no muab GB / T 5231 txwv rau T2 tooj liab. Nyiaj suav nrog tooj liab vim nws coj zoo li tooj liab hauv kev pabcuam. Cov khoom seem yog tuav qis los tiv thaiv conductivity, thiab cov pa oxygen txwv yog qhov sib txawv tseem ceeb ntawm cov suab nrov thiab cov qib deoxidised.
| Element | Limit (wt.%) |
|---|---|
| Copper plus silver | 99.90 yam |
| Oxygen | 0.06 max |
| Tin | 0.002 max |
| Zinc | 0.005 max |
| Coj | 0.005 max |
| Nickel | 0.005 max |

| Antimony, arsenic, sulfur, bismuth | Trace txwv, txhua tus tswj tus kheej |
Cov suab nrov zoo li T2 muaj cov pa oxygen, uas tsis muaj qhov cuam tshuam loj rau kev ua haujlwm lossis kev ua haujlwm ntawm chav tsev kub tab sis dhau los ua teeb meem hauv qhov chaw txo qis. Thaum qhov kub siab tshaj plaws, cov pa oxygen yaj ua rau muaj kev cuam tshuam nrog hydrogen los ua chav nyob ntawm thaj tsam ntawm cov qoob loo, lub tshuab hu ua hydrogen embrittlement. Vim li ntawd, T2 tsis pom zoo rau kev pabcuam lossis kev ua haujlwm siab tshaj li 370 C hauv qhov chaw txo qis, suav nrog kev sib tsoo thiab qee qhov kev ua haujlwm vuam.
Kev sib piv ntawm T2 thiab TP2 Copper Tube
TP2 yog phosphorus -deoxidised khub qib rau T2, thiab ob feem ntau yog muab rau ib sab rau daim ntawv thov raj. Cov phosphorus ntxiv tshem tawm cov pa yaj, uas tshem tawm cov hydrogen embrittlement thiab ua rau TP2 qhov kev xaiv zoo dua rau cov rooj sib txoos welded thiab rau cov cua kub exchanger raj uas yuav tsum tau brazed los yog annealed dua.
| Element | T2 | TP 2 |
|---|---|---|
| Copper plus silver | 99.90 yam | yam 99.85 |
| Phosphorus | Tsis txhob txhob txwm tshaj tawm | 0.013 - 0.050 |
| Oxygen | 0.06 max | 0.01 max |
| Tin | 0.002 max | 0.01 max |
| Hlau | 0.005 max | 0.05 max |
| Nickel | 0.005 max | 0.01 max |
Lub txim me me ntawm cov phosphorus residual nyob rau hauv TP2 tau txais nyob rau hauv pauv rau weldability thiab kev ywj pheej los ntawm hydrogen embrittlement. Ob qib yog muab rau hauv annealed, lub teeb - kos thiab tawv tempers raws li qhov yuav tsum tau muaj zog thiab khoov vojvoog.
Physical thiab Mechanical Properties
Qhov ceev: 8.96 g / cm³, tus nqi siv rau txhua qhov kev suav loj.
Melting point: 1083 C.
Xim: liab doog-liab hauv qhov huv si, tsis muaj oxidized.
Conductivity: siab hluav taws xob thiab thermal conductivity, lub ntsiab yog vim li cas cov qib raug xaiv.
Formability: zoo heev ductility, haum rau khoov, flaring, expanding thiab sib sib zog nqus daim duab.
Kev sib koom ua ke: yooj yim soldered thiab brazed; TP2 yog qhov zoo dua thaum vuam yuav tsum tau ua.
Corrosion: zoo tiv thaiv atmospheric nres thiab rau ntau cov dej ua lag luam.
Xam qhov loj ntawm ib lub raj tooj liab
Tube loj yog xam los ntawm qhov ceev ntawm tooj liab thiab annular cross-section ntawm lub raj. Rau T2 thiab TP2 raj cov qauv kev lag luam yog:
G=8.96 x pi x phab ntsa thickness x (sab nraud txoj kab uas hla - phab ntsa thickness) / 1000
qhov twg G yog qhov hnyav ib 'meter' hauv kilograms, phab ntsa thickness thiab sab nraud txoj kab uas hla yog nyob rau hauv millimeters, thiab 8.96 yog qhov ceev ntawm tooj liab nyob rau hauv grams ib cubic centimeter. Cov lus qhia nyob rau hauv brackets sawv cev rau qhov nruab nrab ntawm cov phab ntsa, yog li cov qauv tsuas yog qhov ntom ntom sib npaug los ntawm tus ntoo khaub lig -sectional cheeb tsam multiplied los ntawm ib 'meter' ntev. Raws li kev ua haujlwm piv txwv, lub raj ntawm 10 hli sab nraud txoj kab uas hla nrog 1 hli phab ntsa muab 8.96 x 3.1416 x 1 x 9 / 1000, lossis txog 0.253 kg ib meter. Tib lub laij lej yog siv los npaj cov lus hais thiab xyuas cov khoom xa tuaj tiv thaiv kev suav loj.
Daim ntawv thov ntawm T2 Ntshav Copper Tube

Kev lag luam hluav taws xob: cov raj xa hluav taws xob, cov khoom sib dhos busbar thiab cov khoom siv hluav taws xob, suav nrog cov tuav electrode thiab EDM electrodes.
Ordering thiab tuav cov ntsiab lus
Ib qho kev txiav txim rau T2 los yog TP2 raj yuav tsum hais txog qib, temper, sab nraud txoj kab uas hla, phab ntsa thickness, ntev, temper kam rau ua, xeem yuav tsum tau thiab tus qauv uas tswj tus me nyuam, piv txwv li GB / T 18033 rau seamless dej raj, ASTM B88 rau dej raj los yog ASTM B280 rau cua txias thiab tub yees. Tube yog ib txwm nkag rau hauv qhov ntev ncaj los yog hauv cov coils mos, ntxuav thiab capped, thiab lub bore yuav tsum qhuav thiab tsis muaj cov roj nplua nyeem ua ntej nws yuav nruab rau hauv lub tub yees. Khaws cov coils thiab qhov ntev kom deb ntawm ammonia thiab sulfur- bearing atmospheres, ua kom qhov kawg kaw kom tsis txhob muaj kab mob sib kis, thiab muab tso rau hauv qhov chaw tswj tau nkaus xwb thaum qib yog tawv pitch tooj liab xws li T2.
FAQ
Q: T2 txhais li cas hauv cov raj tooj liab?
T2 yog GB / T 5231 tsim rau siab - conductivity ntshiab tooj liab uas muaj tsawg kawg yog 99.90% tooj liab ntxiv rau nyiaj, sib npaug rau UNS C11000 thiab Japanese C1100.
Q: Vim li cas nws thiaj li hu ua ntshav tooj liab raj?
High-purity tooj liab muaj qhov txawv liab doog- xim liab nyob rau hauv nws lub cev huv si, uas yog vim li cas nws tau piav raws li ntshav lossis liab tooj liab hauv Suav, thiab lub npe txawv ntawm cov khoom siv tooj dag thiab tooj liab.
Q: Qhov txawv ntawm T2 thiab TP2 yog dab tsi?
TP2 muaj 0.013 - 0.050% phosphorus, uas tshem tawm cov pa oxygen thiab tiv thaiv hydrogen embrittlement, ua rau nws yog qhov kev xaiv zoo dua rau cov welded thiab rov ua dua tshiab. T2 yog qhov nyuaj pitch qib.
Q: T2 tooj liab raj puas tuaj yeem welded?
Nws tuaj yeem raug soldered thiab brazed tau yooj yim, tab sis vuam lossis annealing hauv qhov chaw txo qis yog qhov txaus ntshai tshaj li ntawm 370 C vim tias cov pa oxygen yaj ua rau lub zog tsim thiab tawg. TP2 yog qib kev nyab xeeb rau cov haujlwm ntawd.
Q: Yuav ntsuas qhov hnyav ntawm lub raj tooj liab li cas?
Loj ib ' meter ' nyob rau hauv kilograms sib npaug 8.96 npaug pi lub sij hawm phab ntsa thickness lub sij hawm sab nraum txoj kab uas hla rho phab ntsa thickness, muab faib los ntawm 1000, nrog qhov ntev hauv millimeters.
Q: Yam dab tsi yuav tsum tau txiav txim?
Mos annealed raj yog siv qhov twg khoov kom nruj radii xav tau, thaum lub teeb - kos thiab tempers nyuaj yog xaiv qhov twg muaj zog dua los yog ncaj, tus kheej - txhawb nqa khiav yog yuav tsum tau.
