Txoj cai ntau lawm: ib tug mandrel yog lined nyob rau hauv lub teeb yeeb nkab, tsav los ntawm kev sib hloov ntawm cov menyuam hniav, cov seamless steel yeeb nkab yog ua tiav rau hauv fins nyob rau sab nrauv ntawm seamless steel yeeb nkab los ntawm cov kab noj hniav tsim los ntawm dov zawj thiab mandrel. Lub finned raj tsim los ntawm txoj kev no yog ib qho organic tag nrho vim tias lub hauv paus raj thiab cov fins sab nrauv txuas nrog ua ke, uas yog, lub hauv paus raj thiab cov fins sab nrauv txuas nrog ua ke, yog li tsis muaj teeb meem ntawm kev tiv thaiv thermal tsis zoo, yog li ntawd. kom tau txais high heat transfer efficiency. Piv nrog rau txoj kev vuam,peb-yob skew dov txoj kev muaj qhov zoo ntawm kev ua haujlwm siab, tsis siv cov khoom siv raw, thiab siab kub hloov pauv ntawm cov raj finned tsim.
Peb-yob oblique dov qhov tseem ceeb kauv finned tube tshuab tau ua tiav siv rau ib leeg finned leeg lossis cov hlua sib txuas nrog tooj liab thiab txhuas fins, lossis steel qis finned leeg; steel integral finned tubes yog nyob rau hauv kev ua lag luam. Feem ntau yog cov raj qis-finned, thiab tag nrho cov high-finned raj feem ntau yog ua los ntawm txhuas, tooj liab, thiab lwm yam., uas feem ntau yog txias-dov.
