Qib Identity thiab vim li cas thiaj hu ua Oxygen -Free
C12200, paub thoob ntiaj teb li Cu-DHP lossis deoxidised siab phosphorus tooj liab, yog tsim los ntawm kev ntxiv phosphorus rau cov yaj kom cov pa yaj hauv cov tooj liab sib xyaw ua ke thiab tshem tawm raws li cov slag es tsis nyob hauv qab li cuprous oxide. Cov hlau ua tiav yog li no tseem ceeb tsis muaj oxide theem, thiab nws coj tus cwj pwm hauv kev ua haujlwm zoo ib yam li cov pa oxygen - qib dawb: nws tsis embryo thaum nws rhuab hauv hydrogen lossis ib qho chaw txo qis.
Tus cwj pwm ntawd yog keeb kwm ntawm cov lus piav qhia ntawm C12200 raws li cov pa oxygen -dawb siab - conductivity tooj liab. Cov lus piav qhia yog qhov tseeb hauv cov ntsiab lus engineering tab sis nws xav tau ib qho kev tsim nyog: qhov tseeb oxygen- qib dawb, C10100 oxygen-dawb hluav taws xob thiab C10200 oxygen-dawb, yog tsim los ntawm txoj kev sib txawv thiab nqa ib qho conductivity ntawm 101 % IACS, thaum C12200 yog txhob txwm tshaj tawm txog 5% ntawm oxidIACSs. Ob leeg tiv thaiv kab mob hydrogen; tsuas yog cov pa oxygen tiag tiag- cov qhab nia pub dawb mus txog qhov ua tau zoo tshaj plaws.
Tshuaj muaj pes tsawg leeg thiab qib sib npaug

Lub kaum tsib feem pua ntawm conductivity txim piv rau cov tawv pitch tooj liab yog tus nqi ntawm deoxidation, thiab nws yog me me nyob rau hauv cov khoom siv nyob rau hauv lub tshav kub exchanger nto, raj phab ntsa thiab cov pob qij txha - tsis ntev conductor khiav - dominate tus tsim. Qhov twg txoj kev tam sim no ntev thiab geometry tso cai rau ntu loj, C12200 tseem ua haujlwm tau zoo; qhov twg qhov feem pua ntawm cov conductivity kawg yog qhov tseem ceeb, yuav tsum muaj cov pa oxygen- qib dawb.
Daim ntawv thov thiab kev pabcuam tus cwj pwm
Thaum tshav kub kub exchanger thiab condenser raj, evaporator thiab condenser coils, thiab chiller tube bundles qhov twg raj yuav tsum tau nthuav, U-kov thiab brazed.
Cua- cua txias thiab tub yees kab teeb rau ASTM B280, muab cov khoom huv, qhuav thiab capped.
Cov kav dej, cua sov thiab roj raj rau ASTM B88 thiab EN 1057, suav nrog kev sib koom ua ke thiab brazed.
Busbar, connectors thiab tam sim no - nqa cov khoom siv uas yuav raug brazed lossis annealed hauv kev txo cov cua.
Distiller, desalination thiab marine piping, qhov twg yuav tsum tau ua rau cov av noo thiab chloride - bearing cua.
Automotive radiator, roj txias thiab roj system tube thiab fittings.
Hauv txhua lub luag haujlwm no, deoxidation ua haujlwm tiag tiag: qhov chaw yog brazed, annealed lossis welded, thiab ib qho nyuaj pitch tooj liab nyob rau hauv tib txoj haujlwm yuav muaj kev pheej hmoo ntawm kev tawg hauv lub sijhawm ua haujlwm.
Xaiv Ntawm Deoxidised thiab muaj tseeb Oxygen- Qib Dawb
Pib los ntawm cov txheej txheem, tsis yog cov ntaub ntawv. Yog hais tias ib feem yog brazed, welded los yog annealed nyob rau hauv ib tug hydrogen- bearing cua, oxygen yuav tsum tsis muaj tshuaj lom neeg, thiab yog ib tug deoxidised qib los yog ib tug tiag tiag oxygen - qib dawb yog txais. Yog tias daim ntawv thov kuj xav tau qhov ua tau zoo tshaj plaws - xov tooj cua zaus kab noj hniav, lub tshuab nqus tsev hluav taws xob, cov cuab yeej ntsuas ntsuas qhov tseeb - ces C10100 lossis C10200 yuav tsum tau, vim tias phosphorus hauv cov tshuaj inevitably txo cov conductivity.
Yog hais tias qhov kev xav tau yog tsim, kev tiv thaiv siab, kev tiv thaiv corrosion thiab kev ua haujlwm nruab nrab ntawm tus nqi tswj, C12200 yog cov lus teb ntau dua thiab yog vim li cas nws ua rau cov khoom siv hluav taws xob thiab cov tub yees txias. Txoj kev twg yog xaiv, daim ntawv xaj yuav tsum hais tus qauv, qhov kub thiab txias yuav tsum tau ua los yog tiv taus, thiab daim ntawv pov thawj zeb yuav tsum lees paub cov phosphorus lossis oxygen cov ntsiab lus uas ua rau kev xaiv.
FAQ
Q: Puas yog C12200 tiag tiag yog cov pa oxygen-dawb tooj liab?
Nws yog phosphorus-deoxidised tooj liab uas muaj qhov tseem ceeb tsis muaj oxide, yog li nws coj zoo li oxygen- tooj liab dawb thiab tiv thaiv kab mob hydrogen. Cov pa oxygen tiag tiag- cov qib dawb xws li C10100 thiab C10200 yog tsim tsis muaj phosphorus thiab ncav cuag 101% IACS.
Q: Vim li cas qhov conductivity ntawm C12200 qis dua C11000?
Residual phosphorus yaj nyob rau hauv tooj liab lattice scatters electrons. 0.015% mus rau 0.040% phosphorus ntau yam uas muab deoxidation txwv conductivity txog li 85% IACS.

Yog lawm. Tsis muaj cuprous oxide tam sim no, hydrogen tsis tuaj yeem tsim cov pa hauv cov hlau, yog li annealing thiab brazing hauv kev txo cov cua muaj kev nyab xeeb - kom pom tseeb qhov zoo dua ntawm cov tooj liab tawv.
Q: Qhov twg yog C12200 tooj liab feem ntau siv?
Thaum tshav kub kub exchanger thiab condenser raj, tub yees thiab cua -kub raj, kav dej thiab roj raj, thiab brazed busbar thiab connector hardware.
Q: TP2 txhais li cas?
TP2 yog lub npe rau phosphorus-deoxidised siab-copper tube nyob rau hauv Suav teb tus qauv system thiab yog sib npaug rau UNS C12200 thiab European Cu-DHP.
Q: Qib twg yuav tsum raug xaiv rau cov khoom siv hluav taws xob?
Rau cov neeg xyuas pib ntev uas xav tau 100% IACS lossis ntau dua, xaiv C11000, C10200 lossis C10100. Rau tsim, brazed los yog tshav kub hloov Cheebtsam, C12200 muaj kev ruaj ntseg deoxidation nrog txaus conductivity.
