Integrally Finned Tubes Thiab Tubing Rau Boiler
Khoom siv thiab Specification
Integrally finned tubing thiab tubing rau boilers feem ntau yog tsim los ntawm ntau yam ntaub ntawv, xws li carbon steel, stainless hlau, tooj liab, los yog txhuas alloys. Kev xaiv ntawm cov khoom yog nyob ntawm cov yam ntxwv xws li kev khiav hauj lwm kub, siab, corrosion resistance, thiab kev xav txog nyiaj txiag. Cov hlab no yog tsim los nrog ib qho fins uas muab kev hloov pauv kom muaj peev xwm ua kom sov, ua rau lawv muaj txiaj ntsig zoo rau kev siv boiler.
Qhov ntev specifications ntawm integrally finned tubes sib txawv nyob ntawm seb cov kev cai ntawm lub boiler system. Tus qauv qhov ntev feem ntau suav nrog sab nraud, sab hauv kab, phab ntsa tuab, thiab qhov siab qhov siab. Lub fin pitch, uas yog hais txog tus naj npawb ntawm fins ib chav tsev ntev, yog ib qho tseem ceeb parameter uas cuam tshuam rau tag nrho cov tshav kub hloov efficiency.
Cov yam ntxwv tseem ceeb
Integrally finned raj muaj ob peb yam tseem ceeb uas ua rau lawv haum rau kev siv boiler:
Txhim Kho Thaum tshav kub kub hloov: Cov fins ntawm lub raj sab nrauv ua rau muaj qhov hloov pauv cua sov, uas ua rau muaj kev ua tau zoo dua qub thiab luv dua lub sij hawm hloov hluav taws xob.
Compact Design: Lub fins ib qho qauv tsim tso cai rau thaj tsam ntau dua nyob rau hauv qhov ntev me me, ua rau lawv zoo tagnrho rau cov ntawv thov qhov chaw txwv.
Txo Fouling: Cov qauv finned cuam tshuam lub laminar khiav ntawm cov kua dej, txo cov tsub zuj zuj ntawm deposits los yog fouling ntawm lub raj nto, uas yuav impede tshav kub hloov.
Ua kom muaj zog: Cov txheej txheem finning imparts ntxiv cov txheej txheem lub zog rau lub raj, txhim kho nws tsis kam rau sab nraud siab thiab thermal stresses.
Customizable Configurations: Integrally finned tubes tuaj yeem tsim nrog ntau hom fins, xws li helical, longitudinal, los yog herringbone qauv, nyob ntawm seb qhov kev hloov pauv kub ntawm lub boiler system.

Qib Steel
Cov qib hlau feem ntau siv rau kev sib koom ua ke finned raj rau boilers suav nrog ASTM A179, ASTM A192, ASTM A210, ASTM A213, ASTM A334, thiab ASTM A556. Cov qib steel no muaj cov cuab yeej tsim nyog thiab cov khoom siv tshuaj lom neeg uas xav tau rau kev siv kub thiab kub siab boiler.
Daim ntawv thov
Integrally finned tubes yog dav siv nyob rau hauv ntau yam boiler daim ntaub ntawv, nrog rau cov fais fab nroj tsuag, muaj boilers, pov tseg tshav kub rov qab systems, thiab tshav kub exchangers. Lawv pab txhawb kev hloov pauv kom zoo ntawm cov roj hluav taws xob sib xyaw thiab cov dej los yog cov dej ntws hauv lub boiler, txhim kho tag nrho cov kev ua tau zoo thiab lub zog ua haujlwm.
Cov qhab nia xaiv tau
Thaum cov qib steel tau hais los saum toj no feem ntau yog siv rau hauv kev sib koom ua ke finned boiler raj, lwm qib yuav raug xaiv nyob ntawm seb qhov haujlwm tshwj xeeb. Qee qib lwm yam suav nrog ASTM A106, ASTM A312, ASTM A519, thiab ASTM A213, thiab lwm yam. Kev xaiv ntawm lwm qib yuav tsum xav txog yam xws li qhov kub thiab txias, siab, corrosiveness ntawm cov kua, thiab kev ua raws cai.
