Ultrasonic testing of plate compared to test block - pressure equipment testing ultrasonic non-destructive testing
The plate testing ultrasonic matching block is designed according to the requirements of NB/T4703-2015 plate ultrasonic testing block for pressure equipment. The 1#, 2# test block is suitable for using twin straight probe or single crystal straight probe to detect the plate whose thickness is 6mm < t≤60mm. 3#, 4#, 5#, 6# is suitable for single crystal straight probe to detect the thickness of t > 60mm sheet.
