ASTM cov qauv rau boiler tubing yog dab tsi?
ASTM A192 / ASME SA192 tus qauv npog qhov tsawg kawg nkaus phab ntsa tuab, seamless carbon steel boiler thiab superheater raj rau kev siv siab. Gnee feem ntau muab cov yeeb nkab rau qhov kev qhia tshwj xeeb no hauv qhov ntau thiab tsawg ntawm 1⁄2 nyob rau hauv. mus rau 7 nyob rau hauv. (12.7 txog 177.8 mm) OD thiab 0.085 txog 1. . (0.085 to 1.000 in.) OD.
ASTM A192 / A192M -17. Cov txheej txheem no siv rau cov raj boiler siv hauv cov boilers siab (siab tshaj 350MPa). Cov kav dej yuav tsum tau tiv thaiv kev ua haujlwm nyob rau hauv qhov kub thiab txias thiab muaj kev kub ntxhov thiab muaj kev ua haujlwm zoo thiab lub zog.
ASTM A210 / A210M -19. Cov txheej txheem no siv rau cov raj boiler ntawm qhov qis thiab nruab nrab siab boilers (tsis pub tshaj 500MPa). Nws yuav tsum tau cov yeeb nkab kom muaj kev kub ntxhov thiab kub tsis kam, thiab tuaj yeem tiv taus kev ua haujlwm nyob rau hauv qhov kub thiab txias.
ASTM A213 / A213M ({2}}) Cov qauv no siv rau seamless thiab welded boiler raj siv nyob rau hauv boilers thiab tshav kub exchangers nyob rau hauv kub kub. Nws yuav tsum tau cov yeeb nkab kom muaj peev xwm tiv taus kev ua haujlwm nyob rau hauv qhov kub thiab txias, thiab kom muaj kev tiv thaiv corrosion thiab kub kub.
