Uma kuqhathaniswa neshubhu elifakwe isilonda elivamile, ukumelana nokushisa okuthintana nakho kuhlala kuzinzile ebangeni elikhulu ngokushintsha kwezinga lokushisa, ngakho-ke ukusebenza kokudlulisa ukushisa kwe-bimetallic aluminium extruded finned tube kungcono kune-spiral fin tube in the limit tube wall temperature.
Ngaphezu kwalokho, uma kuqhathaniswa neshubhu elihlanganisiwe, i-bimetallic aluminium extruded fin tube inokumelana nokugqwala okuvelele namandla aphezulu, ingakwazi ukumelana nokuhlanza umfutho wamanzi we-4.0MPa, amaphiko namanje awawi phansi, isisekelo se-bimetallic aluminium extruded tube.I-tube ingakhethwa ngokuvumelana nokugqwala koketshezi ku-tube kanye nobuchwepheshe bokucubungula.I-base tube ingaba yi-carbon steel, ithusi, insimbi engagqwali, njll.
