1. LSAW sawv cev rau dab tsi thiab nws tsim tau li cas?
A:LSAW stands forLongitudinal Submerged Arc Vuam. Nws yog tsim los ntawm kev khoov thiab tsim cov hlau hnyav rau hauv cov duab cylindrical. Lub seam ntev yog tom qab ntawd welded rau sab hauv thiab sab nraud siv cov txheej txheem Submerged Arc Vuam (SAW), uas muab qhov sib sib zog nqus nqus vuam thiab lub zog siab.
2. Dab tsi yog qhov tseem ceeb ntawm cov kav dej LSAW tshaj lwm hom xws li ERW lossis SSAW?
A:Cov txiaj ntsig tseem ceeb yog lawv lub peev xwm los tsim hauv cov kab uas loj dua thiab nrog cov phab ntsa tuab dua, siab dua - cov kabmob muaj peev xwm, thiab lub zog siab, ua rau lawv zoo tagnrho rau qhov tseem ceeb, siab - cov ntawv siv siab xws li roj thiab cov kav xa hluav taws xob.
3. Qhov luaj li cas ntawm cov kav dej LSAW yog dab tsi?
A:LSAW cov kav dej paub txog lawv qhov loj me. Qhov raug sab nraud txoj kab uas hla (OD) ntau yog los ntawm16 nti (406 mm) txog 60 nti (1524 mm) lossis loj dua, nrog phab ntsa thicknesses feem ntau tshaj 1 nti (25.4 mm).
4. Dab tsi yog qhov txawv ntawm JCOE thiab UOE cov txheej txheem tsim rau LSAW kav?
A:Ob leeg yog txoj kev tsim.UAEYuav tsum nias lub phaj rau hauv "U" thiab tom qab ntawd "O" zoo, ua raws li kev nthuav dav. Nws muaj txiaj ntsig zoo rau kev tsim khoom loj.JCOEua cov kauj ruam ntawm phaj-los ntawm- kauj ruam hauv "J", "C", thiab "O" zoo li ua ntej nthuav dav, muab kev yooj yim dua rau qhov sib txawv ntawm cov yeeb nkab loj thiab cov khoom me me.
5. Dab tsi yog qib steel feem ntau siv rau LSAW kav?
A:Lawv yog tsim los ntawm siab -lub zog, qis- alloy (HSLA) carbon steels. Cov qhab nia zoo ib yam API 5L muaj xws liGR B, X42, X52, X60, X65, X70, thiab X80, qhov twg tus lej qhia qhov tsawg kawg nkaus tawm lub zog hauv ntau txhiab psi.
