ASTM A516/ ASME SA516 simbi

ASTM A516/ ASME SA516
SA516 ndeye kabhoni simbi ndiro giredhi rinoshandiswa kunyanya mu welded pressure midziyo yepakati kusvika kudzikisa tembiricha sevhisi. Ichi chinyorwa chinogadzirwa mumagiredhi 55, 60, 65 uye 70. Ichi chinyorwa chinopihwa zvakare mune yakajairika mamiriro apo yakagadziridzwa notch kuomarara kunodiwa.
