Nov yog qee cov ntsiab lus tseem ceeb txog LSAW steel pipes:
Cov Txheej Txheem Vuam: Cov kav hlau LSAW yog tsim los ntawm kev siv ib qho, ob chav, lossis peb zaug submerged arc vuam txheej txheem. Txoj kev no tso cai rau kev vuam zoo, sib xws raws qhov ntev ntawm cov kav dej.
Cov Kab Ntev: Cov txheej txheem vuam tsim cov kab ntev hauv cov yeeb nkab hlau, ua rau muaj kev tsim kho ruaj khov thiab siv tau ntev uas tsim nyog rau ntau yam kev siv.
Muaj Peev Xwm Loj: LSAW cov kav hlau paub txog lawv lub peev xwm los tsim cov kab uas loj, ua rau lawv haum rau cov ntawv thov uas xav tau kev thauj mus los ntawm cov kua dej ntau lossis siv rau hauv cov ntawv thov kev tsim kho.
Daim Ntawv Thov: LSAW cov kav hlau feem ntau siv rau hauv cov ntawv thov xws li cov kav dej xa roj thiab roj, kev teeb tsa, kev txhawb nqa hauv kev tsim kho, thiab lwm yam haujlwm kev lag luam thiab kev tsim kho vaj tse.
Kev Ua Raws Li Cov Qauv: Cov kav hlau LSAW tau tsim thiab tsim tawm los ua kom tau raws li cov qauv kev lag luam thiab cov lus qhia, kom ntseeg tau tias lawv ua tau raws li cov kev cai rau cov ntawv thov tshwj xeeb thiab cov xwm txheej ib puag ncig.
