Ukukhiqizwa komdwebo obandayo we-petroleum cracking tube kungabanda, ukudonswa kubanda, ukukhiqizwa okubandayo, ukuxuba okubandayo. Ukusebenzisa inqubo yokudweba, imishini elula, ukutshalwa kwezimali okuphansi, ukusebenza okulula nokugcinwa njalo njalo. Kodwa i-drawback yisinyathelo esiphakathi kwabaningi, izinga lezinkuni. Ukusebenzisa imishini yenqubo ebandayo kuyinkimbinkimbi kakhulu, kanye nokutshalwa kwezimali okwengeziwe, kodwa kunganciphisa izinqubo eziphakathi nendawo, kuthuthukise isivuno, usayizi womkhiqizo wensimbi engenamthungo ephezulu, kanye nokunemba kwendawo, ikakhulukazi kumashubhu angenamthungo anezimbobo eziphakeme kakhulu anezindonga ezincane kakhulu.

Ngenxa yemikhawulo ye-mill roll pass ngenombolo kanye nezindleko zokucaciswa komkhiqizo ophelile azikwazi ukuba ziningi kakhulu; Inqubo yokukhiqiza ehlanganisiwe ebandayo futhi ebandayo edonsa ukukhiqiza umkhiqizo ophelile, ngekhwalithi enhle yensimbi yokucubungula isikhathi sifushane, ukunciphisa ukuwohloka okuphakathi, ukwelashwa kokushisa, ukuphelelwa amandla, izinqubo eziqondile ze-Jiao, ukonga amandla, ukunciphisa ukusetshenziswa kwensimbi, ukucaciswa okuncane kwempahla eluhlaza kanye njalo njalo. I-petroleum cracking tube ingaba yi-pickling acid ebandayo, i-hydrochloric acid, i-acid exutshwe, i-hydrofluoric acid nokunye okunjalo. Insimbi ye-Carbon ne-alloy steel engenamthungo ngokufanelekile i-sulfuric acid, insimbi yekhwalithi ephezulu ye-carbon structural ne-alloy steel ukunemba okungenamthungo okufanele i-hydrochloric acid.
