C12200 txhais li cas?
C12200 yog UNS (Unified Numbering System) xaiv rauphosphorus{0}}deoxidized tooj liab. Hauv cov ntsiab lus yooj yim, nws yog tooj liab uas tau kho nrog phosphorus thaum lub sij hawm refining kom tshem tawm oxygen.
Qhov no ib kauj ruam - tshem tawm cov pa tawm - ua rau txhua qhov sib txawv.
Tus qauv tooj liab (xws li C11000, tseem hu ua electrolytic tawv pitch tooj liab) muaj cov pa me me. Qhov ntawd yog qhov zoo rau kev siv hluav taws xob. Tab sis rau vuam, brazing, los yog ib yam dab tsi uas muaj cov cua kub siab, cov pa oxygen dhau los ua teeb meem. Nws tuaj yeem ua rau embrittlement, tawg, thiab tsis ua haujlwm ntawm qhov sib koom ua ke.
Tau Txais Cov Qauv Dawb & Kev Ntsuas
C12200 Ua li cas?
Cov txheej txheem tsim khoom yog ncaj nraim. Thaum lub sij hawm refining, phosphorus yog ntxiv rau molten tooj liab. Cov phosphorus reacts nrog oxygen los tsim phosphorus oxides, uas tom qab ntawd tshem tawm. Dab tsi tseem tshuav yog tooj liab nrog cov ntsiab lus oxygen txo mus rau zero- feem ntau qis dua 0.01%.
Qhov tshwm sim yog cov khoom siv uas khaws tag nrho cov txiaj ntsig ntawm cov tooj liab ntshiab tab sis tau txais ib qho txiaj ntsig tseem ceeb: nws tuaj yeem welded, brazed, thiab soldered yam tsis muaj kev pheej hmoo ntawm hydrogen embrittlement.
Qhov no yog vim li cas koj feem ntau yuav pom C12200 hu ua"Deoxidized tooj liab"los yog"DPA" (deoxidized phosphorus arsenic)hauv qee qhov tshwj xeeb.

Yog tias koj khiav hluav taws xob los ntawm lub tsheb npav, C11000 yog tus qauv. Yog tias koj tab tom vuam cov yeeb nkab sib txuas lossis brazing lub raj xa hluav taws xob, C12200 yog qhov kev xaiv zoo dua.
Lwm qhov kev sib piv yog nrogC12200 vs C12000. C12000 kuj yog deoxidized tooj liab tab sis siv cov txheej txheem sib txawv. C12200 muaj ntau dua thiab yog tus qauv xaiv rau kev siv kav dej thiab HVAC hauv North America.
C12200 siv qhov twg?
Cov kav dej thiab cov kav dej siv tau
Tej zaum qhov no yog qhov koj tau pom ntau tshaj plaws. C12200 yog cov khoom siv rau cov kav dej tooj liab hauv thaj chaw thiab cov kav dej ua lag luam. Nws ua tau raws li ASTM B88 tus qauv rau seamless tooj liab raj thiab tau txais kev pom zoo rau cov dej haus. Tsis muaj leaching, tsis muaj teeb meem corrosion, thiab nws yog tus qauv kev lag luam rau ntau xyoo lawm.
Thaum tshav kub kub Exchangers thiab HVAC
Lub siab thermal conductivity ntawm C12200 ua rau nws zoo tagnrho rau tshav kub exchanger raj, condenser coils, thiab radiator cores. Nws hloov cov cua sov kom zoo thiab tiv taus cov thermal cycling ntau hauv HVAC systems.
Industrial Piping
Rau compressed cua, roj kab, thiab cov txheej txheem piping, C12200 yog ib qho kev xaiv txhim khu kev qha. Nws tiv taus corrosion los ntawm ntau cov tshuaj thiab ua haujlwm siab thiab qis kub zoo.
Brazed thiab Welded Assemblies
Yog tias koj daim ntawv thov yuav tsum tau vuam lossis brazing-thiab feem ntau cov kev lag luam sib dhos ua-C12200 yog cov tooj liab uas koj xav tau. Tsis muaj kev pheej hmoo ntawm hydrogen embrittlement txhais tau tias huv si, muaj zog pob qij txha uas kav ntev.
Tub yees Systems
C12200 feem ntau yog siv rau hauv tubing tubing. Nws tswj cov kev ntxhov siab thiab qhov kub thiab txias ntawm lub tshuab tub yees yam tsis muaj teeb meem.
C12200 puas tuaj yeem Welded?
Yog lawm. Thiab qhov ntawd yog tag nrho cov ntsiab lus.
C12200 tau tsim tshwj xeeb los daws cov kev txwv vuam ntawm cov pa oxygen-cov kabmob tooj liab. Nws tuaj yeem welded siv:
TIG welding(Gas tungsten arc vuam)
MIG vuam(gas hlau arc vuam)
Brazing thiab soldering
Qhov tseem ceeb yog vim hais tias cov ntsiab lus ntawm cov pa oxygen yog zero, hydrogen tsis tuaj yeem hnov mob nrog tooj liab oxides los tsim cov hnab ris hauv lub sijhawm thaum vuam. Cov hnab tshos chav no yog dab tsi ua rau embrittlement thiab tawg hauv cov qauv tooj liab. Nrog C12200, koj tau huv, txhim khu kev qha welds txhua lub sijhawm.
