FAQ
Q1: Dab tsi yog qhov txawv ntawm C12200 thiab cov kav dej siv tooj liab uas kuv tuaj yeem yuav ntawm lub khw muag khoom hauv zos?
A: Cov kav dej Standard feem ntau yog C12200 ib yam nkaus, tab sis lawv yuav raug tsim los rau cov qauv ASTM txawv (xws li,ASTM B88rau kev siv dej). Rau kev sib pauv cua sov, condensers, lossis HVAC daim ntawv thov, koj yuav tsum yuav cov raj ua rauASTM B111, B359, lossis B395cov qauv, uas muaj qhov nruj dua qhov ntev ntev thiab cov kev xav tau tshwj xeeb rau kev siv lub tshuab raj nthuav dav.
Q2: Kuv yuav tsum khoov cov hlab no rau hauv U-puab rau lub tshav kub exchanger. Kuv yuav tsum txiav txim siab li cas?
A: Koj yuav tsum tau xaj covO61 (ntxiv)npau taws. Kev kub ntxhov xws li H55 lossis H80 yuav zoo li tawg thaum U- khoov. O61 temper yog qhov muag muag thiab tshwj xeeb rau kev khoov dav dav, raj nthuav dav, thiab ua haujlwm flaring.
Q3: Kuv puas tuaj yeem txuas C12200 raj? Kuv yuav tsum siv cov filler hlau dab tsi?
A: Yog lawm, C12200 tshwj xeeb yog deoxidized nrog phosphorus kom weldable.Nws yog qhov tsim nyog rau vuam ntau tshaj C11000. Rau cov roj tungsten arc vuam (GTAW/TIG), siv lub deoxidized tooj liab muab tub lim xws liERCu(AWS A5.7). Brazing kuj muaj ntau heev thiab pom zoo heev rau raj - mus rau -tubesheet pob qij txha.
Q4: Ua li cas cov thermal conductivity ntawm C12200 piv rau lwm cov khoom siv hluav taws xob xws li stainless hlau lossis Admiralty tooj dag?
A: C12200 muaj thermal conductivity zoo heev(kwv yees.339 W/m-K). Rau kev sib piv:
Admiralty tooj dag (C44300): ~ 111 W/m-K
90/10 tooj liab-nickel (C70600): ~ 45 W/m-K
316 Stainless Hlau: ~ 16 W / m-K
Qhov no ua rau C12200 yog qhov kev xaiv zoo tshaj rau cov ntawv thov uas qhov kev hloov pauv cua sov yog qhov tseem ceeb.
Q5: Puas yog C12200 haum rau kev siv dej hiav txwv?
A: Tsis yog, C12200 feem ntau tsis pom zoo rau kev pabcuam dej hiav txwv ncaj qha, tshwj xeeb tshaj yog nyob rau hauv tus nqi siab dua. Dej hiav txwv tuaj yeem ua rau yaig-corrosion ntawm cov tooj liab ntshiab thiab DHP tooj liab. Rau kev siv dej hiav txwv, koj yuav tsum xaivtooj liab-nickel alloysnyiamC70600 (90/10 Cu-Ni)los yogC71500 (70/30 Cu-Ni), los yogAluminium tooj dag (C68700) .
Q6: Dab tsi yog "DHP" sawv rau?
A: DHP sawv cev rau "Deoxidized High Phosphorus."Nws qhia tau hais tias tooj liab tau deoxidized nrog ntau dua ntawm phosphorus residue, uas txhim kho weldability thiab corrosion kuj piv rau tsis yog -deoxidized los yog tsawg- phosphorus tooj liab.
Q7: Kuv daim ntawv xaj yuav hu rau C12200 lub rooj sib tham ASTM B111. Dab tsi yog qhov yuav tsum muaj cov cuab yeej cuab tam rau H80 temper?
A: Rau C12200 hauv qabASTM B111, covH80 (hloov tau)temper feem ntau xav tau:
Tensile zog: 48 ksi (330 MPa) yam tsawg kawg nkaus
Yield zog: 40 ksi (275 MPa) yam tsawg kawg nkaus
Elongation: 8% yam tsawg kawg nkaus (hauv 2 ntiv tes)
