Dab tsi yog qhov muaj pes tsawg leeg ntawm SA 209 T1?
ASME SA 209 Qib T1 Alloy Steel Seamless Tubesyog Carbon Steel Tubes nrog ntxiv cov chromium, molybdenum thiab qee zaum vanadium hu ua chrome moly Tubes. ASME Specification alloy steel Tubes yog siv rau cov kev pabcuam kub kub.
Cov khoom siv ntawm SA 209 T1 yog dab tsi?
SA209 T1 yeeb nkab yog seamless yeeb nkab ua los ntawm carbon-molybdenum alloy hlau. Nws yog feem ntau siv rau hauv daim ntawv thov xws li boilers, boiler flues thiab superheaters. Cov yeeb nkab yog tsim los tiv taus qhov kub thiab txias, ua rau nws tsim nyog siv rau hauv cov chaw tsim hluav taws xob thiab lwm yam kev siv hauv kev lag luam uas muaj huab cua phem.
