Mrija wa mviringo usio na mshono hutumika kama mirija ya msingi, na mirija iliyochongwa hujeruhiwa kwa mshikamano kwa mkanda wa fin wa alumini au mkanda wa shaba chini ya mvutano na kujeruhiwa kwa nguvu kwenye uso wa nje wa bomba la msingi.
Elliptical Finned Tube imeunganishwa na vifaa viwili tofauti
Nyenzo za bomba la msingi: chuma cha kaboni, chuma cha aloi ya chini, chuma cha pua, shaba, shaba, aloi ya nikeli ya shaba, shaba ya alumini, aloi ya nikeli.
