1. Lo lus nug: Vim li cas A53 Qib B carbon steel yeeb nkab siv dav hauv kev tsim kho engineering?
Teb: A53 Qib B carbon steel yeeb nkab muaj qhov zoo ntawm lub zog siab, zoo weldability, thiab tus nqi qis. Nws yog qhov tsim nyog rau ntau yam kev tsim kho xws li kev tsim kho dej thiab kev tso dej, hluav taws kub - sib ntaus sib tua cov kav dej, thiab kev txhawb nqa cov qauv, yog li nws tau siv dav hauv kev tsim kho engineering.
2. Nqe Lus Nug: Qhov ntsuas kub ntawm Q355C carbon steel yeeb nkab yog dab tsi?
Teb: Q355C carbon steel yeeb nkab yuav tsum muaj kev ntsuam xyuas ntawm -40℃, thiab qhov cuam tshuam lub zog (Akv) yuav tsum tsis pub tsawg dua 34 J. Nws muaj qhov zoo dua qis dua -kub toughness dua Q355B thiab yog haum rau qhov kub thiab txias ib puag ncig.
3. Lo lus nug: 10 # carbon steel yeeb nkab puas tuaj yeem siv rau kev sib sau txias?
Teb: Yog, 10 # carbon steel yeeb nkab muaj kev ua haujlwm txias txias. Nws tuaj yeem ua tau txias - khoov, txias - nias, thiab lwm yam kev ua haujlwm txias yam tsis muaj kev tawg, uas yog tsim rau kev tsim khoom nrog cov duab nyuaj.
4. Nqe lus nug: Dab tsi yog qhov siab tshaj plaws uas A106 Qib B carbon steel yeeb nkab tuaj yeem dais?
Teb: Qhov siab tshaj plaws siab -cov kabmob muaj peev xwm ntawm A106 Qib B carbon steel yeeb nkab nyob ntawm nws phab ntsa thickness thiab kev ua haujlwm kub. Nyob rau hauv ib txwm kub (20 degree), cov yeeb nkab nrog ib txoj kab uas hla ntawm 100 hli thiab phab ntsa thickness ntawm 10 hli tuaj yeem dais siab tshaj plaws ntawm 10 MPa.
5. Nqe lus nug: Txoj kev tiv thaiv corrosion yog dab tsi rau Q235B carbon steel yeeb nkab siv hauv cov kav dej hauv av?
Teb: Rau Q235B carbon steel yeeb nkab siv nyob rau hauv cov kav dej hauv av, cov kev tiv thaiv corrosion feem ntau yog: 1. Kub-dip galvanizing los tsim ib txheej zinc kom cais cov yeeb nkab ntawm cov av; 2. Txheej nrog cov tshuaj tiv thaiv- xeb xim (xws li asphalt xim) txhawm rau txhim kho corrosion; 3. Cathodic tiv thaiv kom qeeb tus nqi corrosion.
