Seamless steel kav txuas ntxiv muab faib ua kub dov thiab txias-kuav los tiag (kos) hom, thiab welded steel kav txuas ntxiv muab faib ua ncaj seam welded steel kav thiab kauv seam welded steel kav.
Cov kav hlau tsis yog tsuas yog siv rau kev xa cov kua dej thiab cov hmoov av, sib pauv lub zog hluav taws xob, tsim cov khoom siv kho tshuab thiab ntim khoom, tab sis lawv kuj yog hom kev lag luam ntawm cov hlau. Siv cov yeeb nkab steel los tsim cov txheej txheem hauv tsev, ncej, thiab kev txhawb nqa tshuab tuaj yeem txo qhov hnyav, txuag hlau los ntawm 20-40%, thiab ua tiav lub Hoobkas kev tsim kho. Kev siv cov kav dej steel los tsim cov choj kev loj tsis tsuas yog txuag cov hlau thiab ua kom yooj yim rau kev tsim kho, tab sis kuj txo qis thaj tsam ntawm cov txheej txheem tiv thaiv, txuag peev thiab kev saib xyuas cov nqi.
