Seamless steel kav yog cov kav dej uas muaj qhov hollow thiab siv ntau ntau li cov kav dej rau kev thauj cov kua dej, xws li cov kav dej rau kev thauj cov roj, roj, roj, roj, dej thiab qee yam khoom siv. Piv nrog rau cov khoom siv hlau xws li cov hlau puag ncig, cov yeeb nkab steel yog sib dua hauv qhov hnyav thaum khoov thiab lub zog torsional zoo ib yam. Nws yog ib qho kev lag luam steel thiab tau siv dav hauv kev tsim hluav taws xob engineering.
Cov txheej txheem ntau lawm ntawm cov kav dej seamless steel tuaj yeem muab faib ua ob hom: txias dov thiab kub dov. Nyob rau hauv tsos, txias-dov seamless steel kav yog luv dua li kub dov seamless steel kav, thiab phab ntsa thickness ntawm txias-dov seamless steel kav yog feem ntau siab dua li ntawm kub dov seamless steel kav. Ua me me. Tab sis qhov saum npoo zoo li ci dua li cov tuab-walled seamless steel yeeb nkab. Tsis muaj roughness ntau ntawm qhov chaw, thiab lub caliber tsis muaj ntau burrs.
Qhov siab tshaj plaws nominal txoj kab uas hla ntawm cov hlab txias yog 200 hli, thiab qhov siab tshaj plaws nominal txoj kab uas hla ntawm cov hlab kub dov yog 600 hli.
