ASTM yog cov txheej txheem ntawm American steel yeeb nkab qauv. Cov qauv suav suav sib raug rau ASTM steel yeeb nkab A106A yog GB8163 nrog cov khoom siv 10 # steel, thiab cov qauv suav nrog A106B yog GB8163 nrog cov khoom 20 #.
ASTM A106B American standard seamless steel yeeb nkab yog cov yeeb nkab zoo steel dav siv nyob rau hauv ntau yam kev lag luam. Nws muaj cov khoom siv zoo heev thiab kev tiv thaiv corrosion, thiab tuaj yeem tswj kev ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias ib puag ncig, yog li nws yog dav siv hauv petrochemical, hluav taws xob, kev tsim kho thiab lwm yam kev lag luam.
