Qhov kub-kub seamless steel yeeb nkabtuaj yeem ua haujlwm hauv qhov chaw txias heev ntawm - 45 ~ - 195 ℃. Qhov zoo tshaj plaws ntawm qhov kub thiab txias seamless steel yeeb nkab yog tias nws tuaj yeem ua haujlwm hauv qhov chaw qis heev, uas yog qhov sib piv nrogzoo tib yam seamless steel yeeb nkab. Cov yeeb nkab uas tsis kub tsis muaj seamless steel yeeb nkab muaj lub zog zoo thiab qhov kub thiab txias, thiab yog siv dav hauv kev tsim cov khoom siv kub qis hauv roj av, tshuaj, chiv thiab lwm yam lag luam nrog kev ua haujlwm kub ntawm - 45 ~ - 195 ℃. Nrog rau txoj kev loj hlob ntawm cov lag luam uas cuam tshuam, cov kev xav tau ntawm cov khoom siv tsis yog tsuas yog txwv rau cov kev cai yooj yim xws li cov khoom siv kho tshuab thiab cov khoom siv vuam, tab sis kuj yog cov kev cai rau H2S corrosion kuj ntawm cov kav dej kub.
Tsawg-kub seamless steel yeeb nkab yog siv rau pipeline engineering nyob rau hauv qhov kub thiab txias ib puag ncig. Nws muaj ob txoj kev: kev kos duab txias thiab kub dov. Los ntawm kev xav ntawm steel tsim, steelmaking, dov, kev kho cua sov thiab lwm yam txheej txheem ntawm qis-kub seamless steel yeeb nkab yuav tsum tau nruj me ntsis tswj xyuas kom meej tias tsis tshua muaj kub seamless steel yeeb nkab muaj zog zoo, toughness thiab corrosion kuj. Rau cov kev cai ntawm qhov kub-kub seamless steel yeeb nkab, lub koom haum tsim khoom thiab cov nqi tsim khoom ntawm cov yeeb nkab steel yuav tsum raug txiav txim siab. Cov qauv tsim ntawm cov yeeb nkab uas tsis muaj qhov kub thiab txias seamless steel yeeb nkab yuav tsum tau xyuas kom meej tias cov khoom muaj lub zog tsim nyog, siab kub tsis tshua muaj zog toughness, thiab yooj yim rau kev kho cua sov txheej txheem Zoo weldability thiab tsis kam mus rau hydrogen-induced cracking.
