Muaj qhov sib txawv loj ntawm atuab-walled steel yeeb nkabthiab nyias-walled steel yeeb nkab nyob rau hauv cov nqe lus ntawm phab ntsa thickness. Yog hais tias txoj kab uas hla ntawm cov yeeb nkab phab ntsa yog ntau tshaj 0.02, peb feem ntau hu nws ib tug tuab-walled steel yeeb nkab. Thick-walled steel kav muaj ntau yam kev siv. Vim lawv cov phab ntsa tuab dua, lawv tuaj yeem tiv taus siab dua. Feem ntau, nws tuaj yeem ua cov khoom siv rau qhov hollow kom tiv taus siab thiab siv rau cov kav dej tseem ceeb. Tshwj xeeb, nws tuaj yeem siv tau los ua cov yeeb nkab ua qauv, roj av geological drilling yeeb nkab, petrochemical yeeb nkab, thiab lwm yam. Thaum siv cov kav dej tuab-walled steel, yuav tsum tau siv cov kev cai lij choj thiab cov cai. Yog li ntawd, cov kav dej sib txawv yuav tsum tau siv rau ntau lub hom phiaj. Qhov no tseem muab qhov tseem ceeb ua ntej rau kev siv cov kav dej tuab-walled steel, tshwj xeeb tshaj yog thaum kev thauj mus los yog qhov txaus ntshai. Nyob rau hauv cov ntaub ntawv ntawm flammable media, nws yog ib qhov tsim nyog los nrhiav cov kav hlau uas tsim nyog los tiv thaiv kev raug mob.

Thick-walled steel kav tuaj yeem siv dav hauv ntau yam kev lag luam hnyav raws li lawv cov qauv thiab cov qauv tshwj xeeb. Yog li ntawd, txoj kev loj hlob ntawm tuab-walled steel kav kuj tsim nyog tos ntsoov kom tau txais. Thick-walled steel kav yog siv rau hauv dej engineering engineering, petrochemical kev lag luam, tshuaj lom neeg kev lag luam, hluav taws xob fais fab kev lag luam, kev ua liaj ua teb irrigation, thiab kev tsim kho hauv nroog. Rau kev thauj mus los ua kua: siv dej thiab tso dej. Rau kev thauj mus los roj: thee roj, nkev, roj av liquefied. Rau kev tsim qauv: piling kav thiab txuas hniav; cov kav dej rau cov docks, txoj kev, thiab cov vaj tse.
