Chitoliro chosasunthika cha ASTM A106 (chomwe chimadziwikanso kuti ASME SA106 chitoliro) chimagwiritsidwa ntchito pomanga malo opangira mafuta ndi gasi, malo opangira magetsi, malo opangira mafuta a petrochemical, ma boilers, ndi zombo pomwe mapaipi amayenera kunyamula madzi ndi mpweya womwe umawonetsa kutentha kwambiri komanso kupanikizika. .
Chitoliro Chopanda Msokonezo cha ASTM A106 (chomwe chimadziwikanso kuti ASME SA106 chitoliro) chimakwirira chitoliro chosasunthika cha carbon chitsulo chomwe chimagwiritsidwa ntchito potentha kwambiri.Oyenera kupindika, kufota ndi ntchito zofananira zopanga.
Chitoliro cha ASTM A106 Grade B ndi chofanana ndi ASTM A53 Grade B ndi API 5L B pa malo opangira mankhwala ndi makina, nthawi zambiri amagwiritsa ntchito zitsulo za carbon ndi mphamvu zolembera zosachepera 240 MPa, mphamvu zamakokedwe 415 Mpa.
Njira zoyesera za ASTM A106 A, B, C ndi mayeso osalala, kuyesa kwa hydrostatic, kuyesa kwamagetsi osawononga, kuyesa kwa Ultrasonic, kuyesa kwa eddy, kuyesa kwa flux leakage, njira zoyesererazi azidziwitsidwa kapena kukambirana ndi kasitomala kuti atsimikizire mtundu wanji wa mayeso adzagwiritsidwa ntchito.
