Q1: Dab tsi yog ERW thiab LSAW sawv rau, thiab dab tsi yog qhov txawv ntawm lawv qhov kev tsim khoom?
A:ERW sawv rauElectric Resistance Vuam. Cov yeeb nkab yog tsim los ntawm kub - dov coil, thiab cov seam yog welded siv hluav taws xob tsis muaj cov hlau muab tub lim. LSAW stands forLongitudinal Submerged Arc Vuam. Nws yog tsim los ntawm steel daim hlau, uas yog khoov thiab ces welded raws lawv longitudinal seam siv submerged arc vuam txheej txheem nrog muab tub lim-2.
Q2: Dab tsi yog qhov loj me me rau ERW thiab LSAW kav?
A:ERW kav dej feem ntau yog tsim nyob rau hauv me me diameters, feem ntau ntawm 1/2 nti mus rau 24 ntiv tes. LSAW kav yog siv rau cov kab loj loj, feem ntau los ntawm 16 ntiv mus rau ntau tshaj 60 ntiv tes, ua rau lawv haum rau cov kav dej loj-2.
Q3: Cov txheej txheem vuam cuam tshuam li cas rau qhov zoo ntawm cov vuam seam?
A:Cov txheej txheem ERW tuaj yeem qee zaum tawm ntawm qhov tsis xws luag hauv qhov vuam zoo li "txias vuam" yog tias tsis tswj nruj-5. Nyob rau hauv sib piv, lub submerged arc vuam siv rau LSAW kav ua ib tug tuab weld hlaws nrog siab nkag, uas ua rau superior mechanical zog thiab zoo nyob rau hauv weld zoo.
Q4: Dab tsi yog cov teeb meem tseem ceeb ntawm cov khoom siv raw hauv kev tsim cov siab - zoo ERW kav?
A:Qhov zoo ntawm ERW kav dej yog nyob ntawm cov hlau sawb. Cov teeb meem tseem ceeb suav nrog cov khoom tsis ruaj khov (lub zog uas siab dhau lossis qis dhau tuaj yeem ua rau tawg lossis tawg), qhov tsis xws luag (xws li mob khoov lossis cov duab wavy), thiab qhov sib txawv ntawm cov duab geometrical, uas suav nrog ntau dua 30% ntawm cov teeb meem zoo-5.
Q5: Dab tsi yog cov txheej txheem tseem ceeb rau LSAW kav?
A:Ob txheej txheem tseem ceeb yogUAE(qhov twg lub phaj yog U- nias, O- nias, thiab nthuav) thiabJCOE(qhov twg lub phaj yog ua kauj ruam-los ntawm- kauj ruam hauv J-C-O duab). UOE feem ntau tso cai rau kev ua haujlwm ntau dua thiab cov yeeb nkab qhov tseeb
