ASTM A335 Standard Specification rau Seamless Ferritic Alloy-Steel Pipe rau Kev Pabcuam Kub.
Qhov kev qhia tshwj xeeb no suav nrog cov phab ntsa nominal thiab phab ntsa yam tsawg kawg nkaus seamless ferritic alloy-steel yeeb nkab npaj rau kev pabcuam kub. Cov kav raj xa mus rau qhov kev qhia tshwj xeeb no yuav tsum tsim nyog rau kev khoov, flanging (vanstoning), kev ua haujlwm zoo sib xws, thiab fusion vuam. Kev xaiv yuav nyob ntawm tus qauv tsim, kev pabcuam, cov khoom siv kho tshuab, thiab cov yam ntxwv ntawm qhov kub thiab txias.
