Hauv kev xaiv SA 333 Gr.6, "SA 333" yog dab tsi?
ASME SA/A333yog ib qho kev qhia tshwj xeeb uas tsim los ntawm American Society of Mechanical Engineers (ASME) rau seamless thiab weldable carbon thiab alloy steel kav tsim los rau cov cheeb tsam cryogenic. Qhov kev qhia tshwj xeeb no suav nrog ntau qib ntawm cov kav hlau uas tsim los rau qhov kub thiab txias ib puag ncig.
ASME SA 333 Gr.6 ERW welded steel yeeb nkab yog dab tsi?
ASME SA 333 Gr.6 ERW welded steel yeeb nkabfeem ntau yog siv rau hauv cov ntawv thov cryogenic hauv kev lag luam xws li roj thiab roj, petrochemicals, thiab hluav taws xob tsim hluav taws xob. Nws cov ntawv tsim qauv tseem ceeb suav nrog cov kav dej rau kev thauj cov kua dej thiab cov pa roj hauv cov xwm txheej cryogenic, cov ntawv thov cryogenic, thiab kev tsim cov hlab ntsha cryogenic.
