Khoom Description
ASTM A333 npog nominal (nruab nrab) phab ntsa seamless thiab welded carbon thiab alloy steel yeeb nkab npaj rau kev siv ntawm qhov kub thiab txias. Muaj ob peb qib ntawm ferritic steel. Qee qhov khoom loj yuav tsis muaj nyob rau hauv qhov kev qhia tshwj xeeb no vim tias cov phab ntsa hnyav dua muaj qhov cuam tshuam tsis zoo rau cov khoom siv hluav taws xob tsawg.
ASTM A333 Qib 6 Carbon Steel Seamless Pipes yog Cov Yeeb Nkab Nruab Nrab Carbon Steel nrog max 0.30 % carbon cov ntsiab lus nrog kev sib xyaw ntawm 0.29 - 1.06 % manganese. Cov Pipes no feem ntau yog siv rau kev siv lub hom phiaj thoob ntiaj teb. ASTM A333 Qib 6 Cov kav dej yog cov kav dej thiab cov kav dej muaj zog nrog cov khoom siv ntev ntev. Cov Pipes no yog tsim raws li ASME Specification thiab kev lag luam hu ua carbon steel Pipes.
A333 Gr.3 muaj cov pa roj carbon tsawg dua, nrog cov ntsiab lus siab tshaj plaws ntawm 0.19%.
