Seamless kav yog tsim los ntawm extruding cov hlau mus rau qhov ntev ntev. Yog li, lawv tsis muaj kev sib koom ua ke hauv nws qhov hla ntu thoob plaws nws qhov ntev.
Cov kav hlau dub yog cam khwb cia los ntawm ntau qib ntawm cov khoom siv hlau los yog cov hlau tsis zoo, hos cov yeeb nkab carbon steel feem ntau welded los yog seamless.

Feem ntau, cov kav hlau dub thiab cov pa roj carbon steel kav yuav luag tib cov txheej txheem rau vuam. Qhov ntawd yog nyob rau hauv cov ntaub ntawv ntawm kev vuam dav dav, tab sis tsis yog qee qhov kev thov tshwj xeeb xws li qhov kub thiab txias heev. Cov yeeb nkab dub tsis yog qhov tshwj xeeb tab sis yog lub ntsiab lus siv feem ntau siv los ntawm cov kav dej kom paub qhov txawv ntawm cov yeeb nkab steel los ntawm galvanized steel yeeb nkab.
