A556 C2 Qib Seamless Steel Yeeb Nkab yog lub siab kub seamless steel yeeb nkab ua raws li American Society of Mechanical Engineers (ASME) tus qauv SA-556M. Qib C2 qhia tau hais tias cov yeeb nkab steel yog tsim rau siv nyob rau nruab nrab siab thiab kub.
Tsim los rau cov ntawv thov siab, cov A556 C2 txias rub cov pa roj carbon steel feedwater rhaub raj feem ntau yog siv rau hauv feedwater rhaub tshuab rau preheat dej ua ntej nws nkag mus rau hauv boiler los tsim chav. A556 C2 carbon steel txias kos seamless steel kav muaj nyob rau hauv cov kav dej ncaj thiab cov uas yuav tsum tau khoov rau hauv "U" zoo li.
