FAQ
Q1: Dab tsi yog qhov txawv ntawm ASTM B68 thiab ASTM B75 rau C12200 raj?
A:ASTM B68 npog annealed seamless tooj liab raj tsim nyog rau siv nyob rau hauv lub tub yees, roj kab, thiab roj av kab uas tsis muaj kev ywj pheej ntawm scale thiab av yuav tsum tau. ASTM B75 npog seamless tooj liab raj rau kev siv engineering. Ob leeg siv cov khoom siv C12200. B68 yog tshwj xeeb rau cov ntawv thov uas xav tau kev huv hauv siab.
Q2: Puas yog C12200 tib yam li ETP tooj liab?
A:No. C12200 yog Deoxidized High Phosphorus (DHP) tooj liab, muaj 0.015-0.040% phosphorus. ETP (Electrolytic Tough Pitch) tooj liab yog C11000, uas muaj cov pa oxygen. C12200 yog weldable thiab brazeable; C11000 tsis yog. Qee tus neeg muag khoom tsis raug sau npe C12200 ua ETP - qhov no tsis yog. Ib txwm txheeb xyuas qib.
Q3: Dab tsi yog qhov hluav taws xob conductivity ntawm C12200?
A:C12200 muaj kwv yees li 85% IACS conductivity. Cov phosphorus ntxiv rau deoxidation txo cov conductivity ntawm 100% IACS (ntshiab tooj liab). Qee qhov chaw tsis raug thov 97-99% IACS rau C12200 - tus nqi ntawd siv rau C11000 ETP tooj liab. Rau cov kev siv high-conductivity, siv C11000. Rau cov kav dej thiab HVAC, C12200 yog tus qauv.
Q4: Qhov txawv ntawm C12200 thiab C12000 yog dab tsi?
A:C12200 (DHP) muaj 0.015-0.040% phosphorus. C12000 (DLP - Deoxidized Tsawg Phosphorus) muaj 0.004-0.012% phosphorus. C12200 muaj deoxidation zoo dua thiab weldability tab sis qis conductivity. C12000 muaj ntau dua conductivity (kwv yees li 90% IACS) tab sis tsis tiav deoxidation. C12200 yog ntau dua rau cov kav dej thiab HVAC.
Q5: Dab tsi yog cov yam ntxwv ntawm ASTM B68 C12200 annealed raj?
A:Rau annealed C12200 raj rau ASTM B68, qhov tsawg kawg nkaus tensile lub zog yog 220 N / mm² (220 MPa), yam tsawg kawg nkaus elongation yog 40%, thiab siab tshaj plaws hardness yog 40 HV (Vickers). Cov txiaj ntsig no qhia tau hais tias lub raj muag muag, haum rau khoov thiab flaring. Hard drawn tempers muaj zog dua tab sis qis dua ductility.
Q6: Dab tsi ntawm C12200 raj ua GNEE muab hauv qab ASTM B68?
A:GNEE muab ASTM B68 C12200 raj nyob rau hauv txoj kab uas hla ntawm 4 hli mus rau 100 hli, phab ntsa thicknesses ntawm 0.6 hli mus rau 6 hli, thiab ntev mus txog 6 meters (ncaj lengths los yog coils). Qhov ntau thiab tsawg yog muaj raws li qhov kev thov. Cov txheej txheem tiav suav nrog ci / polished thiab tiaj. Yam tsawg kawg nkaus kom muaj nuj nqis yog 500 kg.
Q7: Dab tsi yog cov ntawv thov rau ASTM B68 C12200 raj?
A:Cov ntawv thov xws li: cov kav dej, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov tshuab cua txias, cov tub yees, cov roj kab, cov roj av, thiab cov khoom siv hluav taws xob. ASTM B68 tshwj xeeb yog tsim rau cov ntawv thov uas xav tau lub raj tsis muaj nplai thiab av, xws li cov tub yees thiab cov roj.
Q8: C12200 lub raj puas tuaj yeem khoov yam tsis muaj kev tawg?
A:Yog lawm, annealed C12200 raj muaj kev kho tau zoo heev. Nrog tsawg kawg 40% elongation, nws tuaj yeem khoov thiab flared yam tsis muaj tawg. Rau kev khoov teb, siv lub raj bender lossis khoov lub caij nplooj ntoos hlav. Hard drawn tube tsis tuaj yeem khoov yam tsis muaj annealing ua ntej. Rau kev sib sau hnyav, lub sijhawm annealing ntawm 500-600℃yuav tsum tau.
Q9: Dab tsi yog qhov corrosion kuj ntawm C12200 raj?
A:C12200 muaj corrosion kuj zoo heev vim nws cov phosphorus deoxidation thiab ci / polished nto kho. Nws tiv taus corrosion los ntawm dej, av, thiab ntau yam tshuaj. Nws yog tsim rau cov kav dej, cov khoom siv hluav taws xob, thiab kev siv hauv av. Rau cov dej hiav txwv hnyav los yog acidic ib puag ncig, xav txog tooj liab -nickel alloys.
Q10: Cov qauv dab tsi sib npaug rau ASTM B68 C12200?
A:Cov qauv sib npaug suav nrog: BS 2871 Ntu 3 C106 (UK), EN 12451 DHP/Cu-DHP (Tebchaws Europe), JIS H3300 C1220 (Nyiv). Txhua tus muaj cov kev xav tau zoo sib xws (min 99.90% Cu, 0.015-0.040% P). Tubes ua tau raws li cov qauv no yog hloov pauv tau rau feem ntau cov ntawv thov. GNEE tuaj yeem muab rau ib qho ntawm cov qauv no.
Q11: Vim li cas phosphorus ntxiv rau C12200?
A:Phosphorus (0.015-0.040%) yog ntxiv ua tus neeg sawv cev deoxidizing. Nws tshem tawm cov pa oxygen los ntawm cov tooj liab yaj, tiv thaiv hydrogen embrittlement thaum brazing thiab vuam. Yog tsis muaj phosphorus, oxygen hauv tooj liab yuav hnov mob nrog hydrogen los ua chav, ua rau cov kab nrib pleb. Kev lag luam tawm yog txo hluav taws xob conductivity.
