Hauv cov ntsiab lus: ASME SA192 yog cov khoom siv raws cairau seamless carbon steel boiler raj hauvASME Tshooj I stamped boilers. Thaum technically zoo tib yam rau ASTM A192, lubSA kev xaiv tsa muaj txoj cai tswjfwmYuav tsum tau ASME-tso ntawv pov thawj kev tsim khoom, Tso Cai Saib Xyuas Kev Koom Tes, thiab tag nrho cov ntaub ntawv traceability. Rau cov uas tsis yog -code lossis tsis yog -stamped boilers, A192 tej zaum yuav siv tau, tab sis rauKev txiav txim siab boilers raug tshuaj xyuas thiab kev tuav pov hwm, SA192 yog qhov yuav tsum tau ua. Kev qhia kom raug, kev yuav khoom, thiab kev teeb tsa ntawm SA192 raj yog qhov tseem ceeb rau kev ua raws cai thiab kev nyab xeeb ntawm boiler.
