Copper alloyASTM B111 C12200 L hom finned rajyog ib hom kub exchanger raj ua los ntawm ib tug tooj liab alloy hu ua C12200. Cov hlau no yog siab - purity tooj liab nrog qhov tsawg kawg nkaus tooj liab cov ntsiab lus ntawm 99.9%.
L hom finned raj yog hais txog cov duab ntawm cov fins uas txuas rau sab nrauv ntawm lub raj. Lub L- zoo li tus fins nce thaj tsam ntawm lub raj, uas txhim kho cov cua sov ua haujlwm.
Cov raj no feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum tau hloov cov cua kub siab, xws li:
Cua -cooled heat exchangers
Txheej txheem cua sov
Lwm yam kev lag luam kub exchangers
Vim li cas Copper Alloy rau Finned Tubes?
Copper alloy yog cov khoom siv nrov rau finned raj vim nws:
Zoo heev thermal conductivity
Zoo corrosion kuj
Copper alloy L hom finned tubes tuaj yeem tsim nyob rau hauv ntau qhov ntau thiab tsawg thiab kev teeb tsa kom tau raws li cov ntawv thov tshwj xeeb. Tus naj npawb, qhov loj me, thiab qhov sib nrug ntawm cov fins tuaj yeem hloov kho kom zoo dua qhov hloov pauv cua sov thiab cov yam ntxwv siab poob.
Fin Design – L Type
Lub finned tube yog siv rau hauv cov khoom siv hluav taws xob los ua kom cov khoom siv hluav taws xob ntau ntxiv rau cov cua sov. Cov fins feem ntau yog ua los ntawm txhuas lossis tooj liab thiab txuas rau sab nrauv ntawm lub raj los ntawm cov txheej txheem hu ua finning.
L hom fin tsim muab thaj chaw loj dua rau kev hloov hluav taws xob piv rau lwm cov qauv fin. Cov duab "L" yog hais txog tus taw ntawm tus fin, uas yog zoo li tus ntawv L thiab qhwv ib ncig ntawm lub hauv paus raj, muab kev sib txuas zoo thiab kev sib cuag thermal.

FAQ
Q1: L hom finned raj yog dab tsi?
A: Ib hom L hom finned raj muaj fins nrog L-zoo li ko taw uas qhwv ib ncig ntawm lub hauv paus raj. Lub fin yog tsim los ntawm qhwv ib lub hlau sawb (feem ntau yog tooj liab lossis txhuas) nyob ib ncig ntawm lub raj, thiab L- zoo li lub hauv paus muab cov khoom siv xauv thiab kev sib cuag zoo thermal.
Q2: Vim li cas thiaj siv C12200 tooj liab rau finned raj?
A: C12200 tooj liab muaj cov thermal conductivity (kwv yees li 340-360 W / m·K), zoo corrosion kuj nyob rau hauv dej tshiab thiab ntau qhov chaw lag luam, thiab ductility zoo heev rau kev tsim. Nws tseem yog weldable thiab brazeable vim nws cov phosphorus deoxidized chemistry.
Q3: Qhov txawv ntawm L hom, LL hom, thiab KL hom fins yog dab tsi?
A: L hom fins muaj L-puab ko taw. LL hom fins muaj ib tug ntev taw uas qhwv ntxiv nyob ib ncig ntawm lub raj. KL hom fins muaj lub hauv paus tube nrog cov fins embedded. L hom yog qhov ntau tshaj plaws rau cov raj tooj liab hauv qhov tsis yog -corrosive ib puag ncig.
Q4: Cov khoom siv fin puas txawv ntawm cov khoom siv raj?
A: Yog. Thaum ob lub raj thiab fins feem ntau yog tooj liab, fins tuaj yeem yog txhuas. Txawm li cas los xij, cov hlau sib txawv tuaj yeem ua rau muaj kev pheej hmoo corrosion galvanic. Siv C12200 rau ob lub raj thiab fin tshem tawm qhov kev txhawj xeeb no.
Q5: Dab tsi yog qhov siab tshaj plaws ua haujlwm kub rau tooj liab L hom finned hlab?
A: Rau kev pabcuam txuas ntxiv, C12200 tooj liab feem ntau txwv rau 200℃(400℃F). Txoj kev sib txuas fin (L hom) yuav muaj qhov ntsuas kub qis dua nyob ntawm qhov sib txawv ntawm qhov sib txawv ntawm lub raj thiab fin.
Q6: Yuav ua li cas hais txog qhov fin pitch?
A: Fin pitch feem ntau teev nyob rau hauv fins ib nti (FPI) los yog millimeters ntawm fins. Feem ntau yog 4 txog 16 FPI. Cov piv txwv saum toj no qhia 9 FPI. Lub suab ze dua ua rau thaj tsam saum npoo tab sis kuj ua rau huab cua nce ntxiv - sab siab poob thiab muaj kev pheej hmoo ntawm fouling.
Q7: Dab tsi yog qhov dav qhov siab qhov siab?
A: Fin qhov siab feem ntau yog li ntawm 6mm mus rau 16mm (0.25 txog 0.63 ntiv tes), nyob ntawm daim ntawv thov thiab txoj kab uas hla. Piv txwv qhia tau hais tias 9.55mm fin qhov siab.
Q8: Puas yog L hom finned raj tsim nyog rau qhov chaw corrosive?
A: C12200 tooj liab muaj qhov zoo corrosion kuj nyob rau hauv cov dej tshiab thiab ntau qhov chaw ua haujlwm. Rau cov dej hiav txwv los yog ib puag ncig corrosive heev, xav txog finned hlab ua los ntawm cupronickel (C70600, C71500) lossis nrog cov txheej tiv thaiv.
Q9: Cov qauv siv li cas rau L hom finned raj?
A: Lub hauv paus raj feem ntau yog tsim rau ASTM B111 (seamless condenser raj). Cov txheej txheem finning nws tus kheej feem ntau ua rau cov qauv kev lag luam xws li cov los ntawm Tubular Exchanger Manufacturers Association (TEMA).
Q10: Yuav ua li cas kuv thiaj li thov tau cov lus qhia rau tooj liab alloy L hom finned hlab?
A: Thov muab cov ntaub ntawv hauv qab no: lub hauv paus raj OD thiab phab ntsa tuab, cov khoom siv raj, cov khoom siv fin, fin qhov siab, fin thickness, fin pitch (FPI lossis mm), raj ntev, fin ntev, thiab kom muaj nuj nqis. Tiv tauj peb nrog koj cov specifications.
