Txuag tus nqi ntawm kev yuav khoom, kev thauj mus los, kev tshuaj xyuas, kev saib xyuas, thiab kev hloov pauv muaj feem xyuam rau cov kav dej tho thiab laum dab tshos; 3. Vim...Nyeem ntxiv -
Cov teeb meem xav tau kev saib xyuas hauv kev siv cov yeeb nkab tuab-walled steel
Phab ntsa tuab tuaj yeem hu ua tuab-walled steel yeeb nkab. Muaj qee qhov tsis ntseeg txog qhov no. Nws nyob ntawm qhov sib piv ntawm sab nraud ntawm cov yeeb nkab steel rau phab ntsa thickness ntawm cov yeeb nkab steel. Piv txwv li, cov yeeb nkab steel nrog txoj kab uas hla ntawm 50 hli, 10 hli tuaj yeem suav tias yog cov hlau tuab tuab ...Nyeem ntxiv -
Cov txheej txheem ntau lawm ntawm qhov loj-inch ncaj seam steel yeeb nkab
Ib txoj kab loj-ntev longitudinally welded yeeb nkab yog ib lo lus dav dav. Nws yog tsim los ntawm steel sawb. Cov kav dej uas tau welded los ntawm high-frequency welding khoom yog hu ua longitudinally welded kav. (Lub npe tau muab vim tias cov welds ntawm cov yeeb nkab steel yog nyob rau hauv txoj kab ncaj nraim). Ntawm lawv, accordi ...Nyeem ntxiv -
