Piv nrog rau qhov zoo tib yam lub qhov txhab finned tube, kev sib cuag thermal kuj tseem nyob ruaj khov nyob rau hauv ntau yam nrog qhov kub thiab txias, yog li qhov kev hloov pauv kub ntawm bimetallic aluminium extruded finned raj zoo dua li cov kauv fin tube nyob rau hauv qhov txwv tube phab ntsa kub ntau yam.
Tsis tas li ntawd, piv nrog cov coiled raj, lub bimetallic aluminium extruded fin raj muaj qhov zoo tshaj plaws corrosion kuj thiab lub zog siab, nws tuaj yeem tiv taus 4.0MPa dej siab ntxuav, cov fins tseem tsis poob, lub hauv paus ntawm bimetallic aluminium extruded raj.Lub raj tuaj yeem xaiv tau raws li qhov corrosion ntawm cov kua hauv lub raj thiab cov tshuab ua haujlwm.Lub hauv paus raj tuaj yeem yog carbon hlau, tooj liab, stainless hlau, thiab lwm yam.
