Nov yog qee cov ntsiab lus tseem ceeb txog LSAW steel kav:
Vuam txheej txheem: LSAW steel kav yog tsim los ntawm kev siv ib zaug, ob npaug, los yog triple submerged arc vuam txheej txheem. Txoj kev no tso cai rau kev ua haujlwm zoo, tsis sib xws welds raws qhov ntev ntawm cov yeeb nkab.
Longitudinal Seam: Cov txheej txheem vuam tsim cov seam ntev hauv cov yeeb nkab steel, uas ua rau muaj kev siv zog thiab ruaj khov uas haum rau ntau yam kev siv.
Loj Diameter Capability: LSAW steel kav yog paub txog lawv lub peev xwm los tsim nyob rau hauv loj diameters, ua rau lawv haum rau cov kev siv uas yuav tsum tau cov kev thauj mus los ntawm cov dej tseem ceeb los yog siv nyob rau hauv cov ntaub ntawv siv.
Daim ntaub ntawv: LSAW steel kav yog feem ntau siv rau hauv daim ntawv thov xws li roj thiab roj xa cov kav dej, piling, kev txhawb nqa hauv kev tsim kho, thiab lwm yam kev lag luam thiab kev tsim vaj tsev.
Ua raws li Cov Qauv: LSAW steel kav yog tsim thiab tsim kom tau raws li cov qauv kev lag luam thiab cov kev qhia tshwj xeeb, kom ntseeg tau tias lawv ua tau raws li qhov yuav tsum tau ua rau cov kev siv tshwj xeeb thiab ib puag ncig.
