1. Qhov siab tshaj plaws phab ntsa thickness ntawm A106 Qib B seamless carbon steel yeeb nkab yog dab tsi?
Teb: Raws li ASTM A106 tus qauv, qhov siab tshaj plaws phab ntsa thickness ntawm A106 Qib B seamless carbon steel yeeb nkab tuaj yeem ncav cuag 100 hli, uas tuaj yeem ua raws li kev xav tau ntawm engineering, tab sis cov phab ntsa tuab, qhov siab dua qhov yuav tsum tau ua rau kev siv tshuab.
2. Dab tsi yog qhov corrosion kuj ntawm Q235B carbon steel yeeb nkab?
Teb: Q235B yog cov pa roj carbon steel uas tsis zoo corrosion kuj. Nws yog ib qho yooj yim rau xeb hauv huab cua ntub, dej los yog corrosive media. Nws xav tau kev tiv thaiv- kev kho corrosion (xws li galvanizing, painting, anti-corrosion txheej) thaum siv nyob rau hauv ib puag ncig hnyav.
3. Dab tsi yog qib ntawm carbon steel yeeb nkab siv rau hluav taws kub - sib ntaus sib tua pipelines?
Teb: Cov qib siv feem ntau yog Q235B lossis A53 Qib B. Hluav taws kub- cov kav dej sib ntaus sib tua yuav tsum muaj lub siab zoo- cov kabmob muaj peev xwm thiab corrosion kuj (tom qab tiv thaiv- kev kho corrosion), thiab ob qib no muaj cov nqi zoo thiab ua tau raws li qhov hluav taws kub - tawm tsam cov qauv yuav tsum tau ua.
4. Dab tsi yog qhov yuav tsum tau kuaj xyuas rau API 5L Qib B carbon steel yeeb nkab?
Teb: API 5L Qib B carbon steel yeeb nkab yuav tsum muaj kev ntsuam xyuas ntawm 0 degree, thiab qhov cuam tshuam tsawg kawg nkaus yog 27 J (rau cov kav dej nrog txoj kab uas hla Ntau dua lossis sib npaug li 114.3 hli). Qhov kev ntsuam xyuas cuam tshuam kom ntseeg tau tias cov yeeb nkab muaj qhov toughness zoo thiab zam kev tawg tawg hauv qis - qhov kub thiab txias.
5. Cov tshuaj muaj pes tsawg leeg ntawm A333 Qib 6 carbon steel yeeb nkab yog dab tsi?
Teb: A333 Qib 6 yog qhov qis -kub carbon steel yeeb nkab ua raws li tus qauv ASTM A333. Nws lub ntsiab chemical muaj pes tsawg leeg yog C Tsawg dua lossis sib npaug li 0.30%, Mn=0.29-1.06%, P Tsawg dua lossis sib npaug rau 0.035%, S Tsawg dua lossis sib npaug 0.035%, Si Less dua lossis sib npaug rau 0.10%, thiab nws muaj qhov zoo qis -kub toughness, haum rau qis {{11} kev thauj mus los.temperature.
