摘要
简述在用压力容器超声检测的特点,列举了换热器、焦炭塔、球罐、管道及加氢反应器等典型容器的超声检测要点,最后介绍了超声衍射时差法。
Ultrasonic testing of the plates, pipes and tubings, forgings, bolts, welds and overlaid claddings used for pressure vessels was introduced, including probe selection, scanning mode, defect discrimination and quality classification. Three methods for determining the height of defects were given.
