Cov yeeb nkab steel yog ib hom hlau nrog hollow seem, nws qhov ntev yog ntau dua li txoj kab uas hla lossis ib ncig. Nws tau muab faib ua voj voog, square, duab plaub thiab tshwj xeeb-puab steel kav raws li cov duab seem; Nws tuaj yeem muab faib ua carbon structural steel yeeb nkab, qis alloy steel yeeb nkab, alloy steel yeeb nkab thiab puas steel yeeb nkab raws li cov khoom siv; Nws tuaj yeem muab faib ua cov kav hlau xa mus rau cov kav xa dej, cov qauv tsim vaj tsev, cov khoom siv thermal, kev lag luam petrochemical, kev tsim cov tshuab, geological drilling, cov cuab yeej siv siab, thiab lwm yam; Raws li cov txheej txheem ntau lawm, nws tuaj yeem muab faib ua seamless steel yeeb nkab thiab welded steel yeeb nkab. Seamless steel yeeb nkab yuav muab faib ua kub dov thiab txias dov, thiab welded steel yeeb nkab yuav muab faib ua ncaj seam welded steel yeeb nkab thiab kauv seam welded steel yeeb nkab.
Cov yeeb nkab steel tsis yog tsuas yog siv los thauj 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 kuj yog cov hlau lag luam. Siv cov yeeb nkab steel los tsim cov qauv hauv tsev, cov ncej thiab cov cuab yeej txhawb nqa tuaj yeem txo qhov hnyav, txuag 20 ~ 40 feem pua ntawm cov hlau, thiab paub txog kev tsim kho tshuab. Kev siv cov yeeb nkab steel los ua cov choj loj tuaj yeem tsis tsuas yog txuag cov ntaub ntawv steel thiab ua kom yooj yim rau kev tsim kho, tab sis kuj txo qis thaj tsam ntawm kev tiv thaiv txheej, txuag peev thiab kho cov nqi.
