Lub tshav kub exchanger yog cov khoom siv hluav taws xob hloov hluav taws xob uas siv rau kev hloov pauv ntawm lub zog thermal sab hauv ntawm ob lossis ntau dua cov kua dej muaj nyob rau ntawm qhov sib txawv.Lub raj lossis lub raj yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, uas cov kua dej ntws tawm.Txij li thaum tshav kub exchangers yuav siv tau nyob rau hauv cov txheej txheem, lub hwj chim, roj av, tsheb thauj mus los, cua txias, tub yees, cryogenic, tshav kub rov qab, alternate fuels, thiab lwm yam lag luam, tshav kub exchanger tubes kuj muab faib raws li cov raj radiators, regenerators, condensers, superheaters. , preheaters, coolers, evaporators, thiab boilers.Thaum tshav kub kub exchanger raj tej zaum yuav muab nyob rau hauv ncaj hom, U-bent hom, coiled hom, los yog serpentine style.Feem ntau, lawv yog seamless los yog welded hlab muaj nyob rau sab nraud diameters ntawm 12.7 hli thiab 60.3 hli nrog cov phab ntsa nyias.Cov raj feem ntau yog sib koom nrog cov tubesheet los ntawm kev dov lossis vuam txheej txheem.Qee zaum, cov raj capillary lossis txoj kab uas hla loj yog siv tau.Lub raj tuaj yeem muab kho nrog cov fins (finned tube) uas muab kev ua kom muaj cua sov hloov tau zoo.
1. Kev xaiv cov khoom siv rau lub tshav kub Exchanger Tubing
Hauv kev xyaum ua engineering, kev xaiv cov khoom siv rau cov cua kub exchanger tubing yuav tsum tau ua nruj me ntsis.Feem ntau, cov tubing yuav tsum ua raws li cov lus qhia tshwj xeeb hauv ASME Boiler thiab Pressure Vessel Code Tshooj II.Kev xaiv cov khoom siv yuav tsum ua raws li kev xav thiab kev suav ntawm kev ua haujlwm siab, qhov kub thiab txias, tus nqi ntws, corrosion, yaig, kev ua haujlwm, kev ua haujlwm zoo, viscosity, tsim, thiab lwm yam.Feem ntau, lub tshav kub exchanger tubing tuaj yeem muab tso rau hauv ferrous lossis nonferrous hlau cov ntaub ntawv, uas tuaj yeem raug cais tawm ntxiv xws li carbon steel, qis alloy steel, stainless hlau, duplex stainless hlau, npib tsib xee alloy, titanium alloy, tooj liab alloy, aluminium alloy, tantalum thiab zirconium thiab lwm yam.
Cov txheej txheem tshwj xeeb ntawm cov ntaub ntawv suav nrog: ASTM A178, A179, A209, A210, A213, A214, A249, A250, A268, A334, A423, A450, A789, A790, A803, A1016;ASTM B75, B111, B135, B161, B165, B165, B167, B210, B221, B234, B251, B315, B338, B359, B395, B407, B423, B444, B466, B565, B468, B622 .B626, B668, B674, B676, B677, B690, B704, B729, B751 thiab B829.Cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab kev kho cua sov yuav tsum ua raws li cov qauv sau tseg saum toj no.Lub tshav kub exchanger tubing tuaj yeem tsim los ntawm cov txheej txheem kub lossis txias.Ntxiv mus, cov txheej txheem ua haujlwm kub ua rau nyias thiab ntxhib dub sib nqus hlau oxide zaj duab xis ntawm nws qhov chaw.Cov yeeb yaj kiab no feem ntau hu ua "mill scale" uas yuav tsum tau muab tshem tawm tom qab los ntawm txoj kev tig, polishing, los yog pickling txheej txheem.
2. Kev kuaj thiab tshuaj xyuas
Kev ntsuam xyuas thiab kev soj ntsuam ntawm cov cua kub exchanger raj feem ntau suav nrog kev kuaj pom, ntsuas qhov ntsuas, ntsuas tam sim no, ntsuas ntsuas hydrostatic, pneumatic huab cua hauv qab dej ntsuas, ntsuas particle sib nqus, kuaj ultrasonic, kuaj corrosion, ntsuas txhua yam (xws li tensile, flaring, flattening, thiab rov qab kev sib tw flattening), tshuaj ntsuam xyuas (PMI), thiab X-ray tshuaj xyuas ntawm cov welds (yog tias muaj).
