ASTM A333 Rau Hlau Yeeb Nkab rau Kev Pabcuam Kub Kub - Kev Paub

ASTM A333 Txuj Specification rau Seamless thiab Welded Steel Yeeb Nkab rau Kev Pabcuam Kub Kub

Qhov kev qhia tshwj xeeb no suav nrog nominal (nruab nrab) phab ntsa seamless thiab welded carbon thiab alloy steel yeeb nkab npaj rau kev siv ntawm qhov kub thiab txias. Ob peb qib ntawm ferritic steel tau suav nrog raws li teev nyob rau hauv Table 1. Qee qhov ntau thiab tsawg ntawm cov khoom yuav tsis muaj nyob rau hauv cov lus qhia no vim tias cov phab ntsa hnyav dua muaj qhov cuam tshuam tsis zoo rau cov khoom siv hluav taws xob tsawg.

Qhov kev qhia tshwj xeeb no ASTM A333 suav nrog ntau qib xws li Qib 1, 3, 4, 6, 7, 8, 9, 10, thiab 11.
