Cov pa roj carbon steel kav tau paub txog lawv lub zog thiab ua haujlwm ntev, ua rau lawv tau siv dav hauv ntau lub lag luam rau kev thauj cov kua dej thiab cov pa roj hauv qhov kub thiab txias. Lub zog ntawm cov pa roj carbon steel kav yog nyob ntawm ntau yam, nrog rau qib ntawm carbon steel siv, kev tsim khoom, thiab phab ntsa thickness.
Cov pa roj carbon steel kav feem ntau yog tsim los ntawm ntau qib, xws li ASTM A53, ASTM A106, API 5L, thiab lwm yam. Txhua qib muaj cov yam ntxwv tshwj xeeb thiab cov yam ntxwv ntawm lub zog. Cov qib siab tshaj plaws rau cov kav dej carbon steel yog A53 Qib B thiab API 5L Qib B, uas muaj qhov ua tau zoo ntawm 35, 000 psi (240 MPa) thiab 42, 000 psi (290 MPa), raws. Cov qib no muaj lub zog zoo rau feem ntau cov ntawv thov.
Ntxiv rau qib, phab ntsa tuab ntawm cov yeeb nkab carbon steel kuj cuam tshuam rau nws lub zog. Thicker phab ntsa muab lub zog muaj zog thiab tuaj yeem tiv taus siab dua thiab kev ntxhov siab. Hloov pauv, cov kav dej nyias nyias tuaj yeem tsim nyog rau kev siv qis dua, tab sis yuav muaj zog dua.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov yeeb nkab carbon steel tuaj yeem muaj qhov sib txawv nyob ntawm seb lawv xav siv thiab cov kev cai tshwj xeeb ntawm daim ntawv thov. Cov yam ntxwv xws li qhov kub thiab txias, kev ua haujlwm, thiab kev txiav txim siab tsim yuav tsum raug coj mus rau hauv tus account thaum txiav txim siab lub zog tsim nyog rau cov yeeb nkab carbon steel.
Hauv cov ntsiab lus, carbon steel kav feem ntau paub txog lawv lub zog, thiab lub zog tshwj xeeb yog nyob ntawm qib ntawm carbon steel thiab phab ntsa thickness ntawm cov yeeb nkab. Rau cov kev xav tau ntawm lub zog, nws raug nquahu kom sab laj txog cov qauv kev lag luam thiab cov lus qhia tshwj xeeb los yog sab laj nrog tus kws tshaj lij lossis cov chaw tsim khoom.
