Tus nqi ntawm 6-meter seamless steel yeeb nkab tau ntau dua li ntawm 12-meter steelless steel siv tau,

Thaum muas khoom seamless steel kav, xav txog qhov sib txawv. Piv txwv li, lub phab ntsa tuab ntawm cov yeeb nkab steel nrog txoj kab uas hla ntawmASTM A106 GRB159 * 6 Tej zaum 159 * 6.2 nrog lub phab ntsa tuab ntawm 6.2 hli. Yog tias qhov sib txawv tsis tau txiav txim siab, cov nyiaj them yuav tau them dua thaum lub cev hnyav. Txawm li cas los xij, cov txheej txheem ntau tam sim no tuaj yeem ua tiav tsis muaj qhov sib txawv, uas yog kev txhim kho zoo hauv cov yeeb nkab steel tsis muaj kev lag luam.

Ntau cov kav hlau seamless hlau tsis hloov hauv qhov ntev. Qee tus neeg yuav yog 8-9 meters, 8.5 meters, 8.3 meters, lossis 8.4 meters, tab sis koj tuaj yeem qhia los ntawm cov duab ntawm cov khoom yog tias nws yog tsau lossis tsis. Piv txwv li, cov khoom hauv qab no yog tsau nyob rau hauv ntev ntawm 12 meters thiab yog ua tau zoo huv heev.
