ASTM A192 / A192M - 17 Seamless Carbon Steel Boiler Tubes rau Siab -Kev Pab Cuam Siab
A192 siab-siab seamless steel yeeb nkab, ua raws li cov qauv xws li ASTM A192/ASME SA192, tshwj xeeb yog tsim los rau siab -siab boiler systems nrog siab tshaj plaws ua hauj lwm siab ntawm 9.8 MPa thiab kub ntawm 450℃-650℃. Nws npog cov khoom tseem ceeb xws li boiler cua sov cov kav dej, superheaters, thiab kev lag luam. Nws qib raug yog A192, uas tuaj yeem tsim los ntawm kev kos duab txias lossis cov txheej txheem kub. Sab nraud txoj kab uas hla yog 12.7-177.8 hli, thiab qhov tsawg kawg nkaus phab ntsa thickness yog 2.2-25.4 hli. Cov kav dej txias txias yuav tsum tau kho cua sov ntawm qhov kub tsis tsawg tshaj 650℃tom qab ua tiav.
