ASTM B111 Kev Ntsuas thiab Cov Qauv Zoo
Peb cov raj tooj liab alloy yog tsim nyob rau hauv nruj raws liASTM B111 tus qauv, kom ntseeg tau qhov zoo tshaj plaws thiab kev ntseeg siab. Kev ntsuam xyuas tseem ceeb thiab cov kev xav tau zoo muaj xws li:
Chemical Composition Analysis:
Xyuas kom meej qhov sib piv ntawm tooj liab, txhuas, thiab zinc rau qib C68700.
Txheeb xyuas siv spectrometers kom meej meej.
Mechanical Properties Testing:
Lub zog tensile, lub zog tawm los, thiab elongation raug kuaj xyuas kom ua tau raws li ASTM cov qauv.
Tej yam khoom siv rau C68700:
Tensile zogUa haujlwm siab: 310-500 MPa
Yield zog: Ntau dua lossis sib npaug rau 105 MPa
Elongation: Ntau dua lossis sib npaug li 30%
Hydrostatic thiab Eddy Current Testing:
Tag nrho cov raj tau txais kev kuaj hydrostatic kom tsis txhob muaj cov pa paug hauv qhov siab.
Eddy tam sim no kuaj pom qhov chaw thiab subsurface defects.
Dimensional soj ntsuam:
Sab nraud txoj kab uas hla, phab ntsa thickness, thiab ntev yog ntsuas nrog nruj tolerances los lav precision.
Nto Zoo:
Tubes tsis muaj qhov tsis xws luag xws li tawg, dents, lossis deformities, kom ntseeg tau tias kev ua haujlwm tsis zoo.
Daim ntawv thov ntawm C68700 Copper Alloy Tubes
Ua tsaug rau lawv zoo heev corrosion kuj, siab thermal conductivity, thiab mechanical zog,C68700 Copper Alloy Tubesyog dav siv nyob rau hauv ntau yam lag luam, xws li:
Thaum tshav kub kub Exchangers:
Siv nyob rau hauv fais fab nroj tsuag, tshuaj ua, thiab petrochemical industries kom tau txais hluav taws xob hloov.
Condenser thiab evaporators:
Zoo tagnrho rau kev siv marine thiab kev lag luam, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog dej hiav txwv raug.
Desalination Nroj tsuag:
Feem ntau siv nyob rau hauv desalination systems vim lawv tsis kam rau seawater corrosion.
Kev lag luam roj thiab roj:
Haum rau offshore platforms thiab refineries qhov twg hnyav ib puag ncig xav tau cov ntaub ntawv txhim khu kev qha.
HVAC Systems:
Dav siv nyob rau hauv cua sov, qhov cua, thiab cua txias tshuab kom zoo thermal exchanger.
Shipbuilding:
Siv nyob rau hauv marine condensers, coolers, thiab piping systems vim superior tsis kam mus biofouling.
