A heat exchanger mudziyo wekutamisa kupisa unoshandiswa kutamisa simba remukati rekushisa pakati pezvinwiwa zviviri kana kupfuura zvinowanikwa patembiricha dzakasiyana.Iyo tubing kana chubhu chinhu chakakosha cheinopisa kupisa, iyo iyo mvura inoyerera.Sezvo magetsi ekupisa angashandiswa mukuita, simba, peturu, kufambisa, mhepo inogadzirisa, firiji, cryogenic, kudzoreredza kupisa, mamwe mafuta, uye mamwe maindasitiri, machubhu ekupisa anogona kuverengerwa zvinoenderana semachubhu eradiator, regenerator, condensers, superheaters. , preheaters, cooler, evaporators, uye boilers.Machubhu ekupisa anogona kupihwa nemhando yakatwasuka, U-bent type, coiled type, kana serpentine style.Kazhinji, iwo haana musono kana welded machubhu anowanikwa kunze kwemadhayamita ari pakati pe12.7 mm ne60.3 mm ane madziro akatetepa.Iyo machubhu anowanzo kubatanidzwa ne tubesheet ne rolling kana welding process.Mune zvimwe zviitiko, capillary tubing kana yakakura-diameter tubing inoshanda.Iyo chubhu inogona kupihwa zvimbi (finned chubhu) inopa yakawedzera kupisa-kutamisa kushanda.
1. Kusarudzwa kwezvinhu zveKupisa Exchanger Tubing
Muchiito cheinjiniya, kusarudzwa kwezvinhu zvekupisa exchanger tubing kuchaitwa zvine hukasha.Kazhinji, iyo tubing ichave ichienderana neiyo yakapihwa muASME Boiler uye Pressure Vessel Code Chikamu II.Sarudzo yezvinyorwa ichave yakavakirwa pakufunga kwese uye kuverenga kwekumanikidza kwekushanda, tembiricha, chiyero chekuyerera, ngura, kukukurwa, kugona kushanda, mutengo wakanaka, viscosity, dhizaini, uye mamwe nharaunda.Kazhinji, kupisa kunopisa tubing kunogona kupihwa mune ferrous kana nonferrous simbi zvinhu, izvo zvinogona kuverengerwazve sekabhoni simbi, yakaderera alloy simbi, Stainless simbi, duplex Stainless simbi, nickel alloy, titanium alloy, copper alloy, aluminium alloy, tantalum uye zirconium nevamwe.
Izvo zvakajairwa zvimiro zvemidziyo zvinosanganisira: ASTM A178, A179, A209, A210, A213, A214, A249, A250, A268, A334, A423, A450, A789, A790, A803, A1016;ASTM B75, B111, B135, B161, B165, B167, B210, B221, B234, B251, B315, B338, B359, B395, B407, B423, B444, B466, B455, B3 B3 B1 622 .B626, B668, B674, B676, B677, B690, B704, B729, B751 uye B829.Kuumbwa kwemakemikari, mechanical properties uye kupisa kupisa zvose zvinopindirana nemaitiro ataurwa pamusoro apa.Iyo inopisa exchanger tubing inogona kugadzirwa nekupisa kana kutonhora maitiro.Zvakare, iyo inopisa yekushanda maitiro inogadzira yakaonda uye yakaomarara dema magineti iron oxide firimu pamusoro payo.Iri rudzi rwefirimu rinowanzodaidzwa kuti "mill scale" iro rinozobviswa nekutendeuka, kupukuta, kana kuita pickling.
2. Kuedza uye Kuongorora
Kuongororwa kwakajairwa uye kuongororwa pamachubhu ekupisa kupisa kunowanzo sanganisira kuongororwa kwekuona, kuongororwa kwedimensional, eddy ikozvino bvunzo, hydrostatic pressure test, pneumatic air-pasi pemvura bvunzo, magineti particle test, ultrasonic test, corrosion test, mechanical tests (kusanganisira tensile, flaring, flattening, uye reverse flattening test), makemikari ekuongorora (PMI), uye X-ray kuongorora pane welds (kana iripo).
