Marka la barbar dhigo tuubada finned ee nabarka caadiga ah, iska caabbinta kulaylka xidhiidhka ayaa weli ah mid deggan oo kala duwan oo leh isbeddelka heerkulka, sidaa darteed waxqabadka wareejinta kulaylka ee tuubada bimetallic ee tuubada finned ee finned waxay ka fiican tahay tuubada finne ee xadka heerkulka xadka tuubada.
Intaa waxaa dheer, marka la barbar dhigo tuubada duuban, tuubada bimetallic aluminium extruded tube fin waxay leedahay iska caabin heer sare ah iyo awood sare, waxay u adkeysan kartaa nadiifinta cadaadiska biyaha ee 4.0MPa, baalku wali ma dhicin, saldhigga bimetallic aluminium tube extruded.Tuubada waxaa lagu dooran karaa iyadoo loo eegayo daxalka dareeraha tuubada iyo farsamada farsamaynta.Tuubada salku waxay noqon kartaa birta kaarboonka, naxaasta, birta aan lahayn, iwm.
