1. Dab tsi yog qhov txawv ntawm 10 # thiab 20 # carbon steel seamless kav nyob rau hauv cov nqe lus ntawm kev ua tau zoo?
Teb: Ob leeg yog cov pa roj carbon tsawg. 20# muaj cov ntsiab lus carbon siab dua 10#, yog li nws lub zog tensile thiab lub zog tawm los me ntsis siab dua 10#, tab sis cov yas qis dua me ntsis . 10# yog qhov tsim nyog rau qee lub sijhawm uas xav tau cov yas siab, thiab 20# yog qhov tsim nyog rau qee lub sijhawm xav tau lub zog siab dua me ntsis.
2. Vim li cas 16Mn carbon steel seamless yeeb nkab siv dav dua 45 #?
Teb: 16Mn muaj kev ua tau zoo dua: nws muaj zog dua li cov pa roj carbon zoo tib yam (10 #, 20 #) thiab zoo weldability thiab toughness dua 45 #. Nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm feem ntau nruab nrab thiab siab siab thiab thauj khoom - lub sijhawm ua haujlwm, yog li nws tau siv ntau dua.
3. Dab tsi yog qhov tsawg tshaj plaws khoov vojvoog ntawm carbon steel seamless yeeb nkab?
Teb: Nws nyob ntawm cov yeeb nkab txoj kab uas hla, phab ntsa thickness thiab cov khoom. Rau qhov zoo tib yam 20# seamless yeeb nkab, qhov tsawg kawg nkaus dabtsi yog khoov vojvoog feem ntau yog 3-5 npaug ntawm txoj kab uas hla; rau tuab- cov kav dej uas muaj phab ntsa lossis cov khoom siv siab 45 # cov kav dej, qhov tsawg kawg nkaus khoov vojvoog yuav tsum tau nce mus rau 5-8 zaug kom tsis txhob muaj cov yeeb nkab tawg.
4. Cov pa roj carbon steel seamless kav siv tau los thauj cov xov xwm corrosive?
Teb: Feem ntau tsis pom zoo. Cov pa roj carbon steel tsis zoo corrosion kuj thiab yooj yim rau corrode thaum sib cuag nrog corrosive media (xws li kua qaub, alkali, dej ntsev). Yog tias tsim nyog siv nws, kev tiv thaiv kev tiv thaiv - kev kho corrosion (xws li hauv ob sab phlu yas, anti-corrosion txheej) yuav tsum tau nqa tawm ntawm phab ntsa sab hauv.
5. Dab tsi yog qhov txawv ntawm seamless yeeb nkab thiab ERW welded yeeb nkab ntawm 16Mn khoom?
Teb: 16Mn seamless yeeb nkab tsis muaj vuam seam, kev kub siab ua haujlwm thiab kev ua haujlwm zoo qaug zog, haum rau siab - siab thiab siab - qhov kub thiab txias; 16Mn ERW welded yeeb nkab muaj vuam seam, tus nqi qis, tab sis qis dua - bearing muaj peev xwm tshaj seamless yeeb nkab, haum rau tsawg thiab nruab nrab siab zaus.
