FAQ
Q1: SMLS sawv rau dab tsi?
A: SMLS yog cov ntawv luv rau "seamless." Seamless raj yog tsim los ntawm kev tho ib lub pob zeb thiab kos duab los yog extruding mus rau qhov kawg qhov ntev, tsis muaj longitudinal weld seam. Qhov no tshem tawm txoj kev pheej hmoo ntawm kev sib tsoo tsis ua haujlwm thiab muab cov phab ntsa tuab thiab cov khoom sib xws.
Q2: Dab tsi yog qhov txawv ntawm ASTM B111 thiab ASTM B75 rau C12200 raj?
A: ASTM B111 yog tshwj xeeb rau seamless condenser thiab kub exchanger tubes, nrog nruj dua qhov ntev kam rau ua thiab kev ntsuam xyuas ntxiv rau cov kev pab cuam hloov tshav kub. ASTM B75 yog ib qho kev qhia tshwj xeeb engineering rau seamless tooj liab raj. Rau kev siv hluav taws xob sib hloov, B111 yog tus qauv tsim nyog.
Q3: Vim li cas C12200 muaj qis conductivity dua lwm qib tooj liab?
A: Cov ntsiab lus phosphorus (0.015-0.040%) siv rau deoxidation scatters electrons, txo cov hluav taws xob thiab thermal conductivity. C12200 feem ntau muaj 70-90% IACS (International Annealed Copper Standard) conductivity, piv rau 100% + rau oxygen-dawb lossis tawv pitch tooj liab.
Q4: Puas yog C12200 haum rau vuam?
A: Yog. C12200 tshwj xeeb yog deoxidized los tiv thaiv hydrogen embrittlement thaum vuam. Nws tuaj yeem welded siv TIG lossis oxy- cov txheej txheem acetylene nrog deoxidized muab tub lim (ERCu). Qhov no yog qhov txiaj ntsig tseem ceeb tshaj qhov tsis yog -deoxidized tooj liab qib xws li C11000.
Q5: Qhov txawv ntawm C12200 thiab C12000 yog dab tsi?
A: Ob leeg yog phosphorus deoxidized tooj liab. C12200 muaj phosphorus residual ntau dua (0.015-0.040%) thiab yog tus qauv deoxidized tooj liab qib. C12000 muaj phosphorus qis (0.004-0.015%) thiab tsawg dua. C12200 yog dav dav thiab teev rau feem ntau daim ntawv thov.
Q6: Dab tsi yog qhov siab tshaj plaws ua haujlwm kub rau C12200 raj?
A: Rau kev pabcuam txuas ntxiv, C12200 feem ntau txwv rau 200℃(400℃F). Tshaj qhov kub no, lub zog txo qis sai thiab oxidation accelerates. Lub sij hawm luv luv - raug rau qhov kub siab dua tuaj yeem siv tau rau kev sib tsoo lossis brazing.
Q7: C12200 puas tuaj yeem siv rau hauv dej hiav txwv?
A: C12200 tsis pom zoo rau kev pabcuam dej hiav txwv. Thaum nws muaj corrosion kuj zoo nyob rau hauv dej tshiab, nws yuav corrode nyob rau hauv seawater. Rau cov ntawv thov dej hiav txwv, xav txog C70600 (90/10 tooj liab-nickel) lossis C71500 (70/30 tooj liab-nickel).
