The issue of steel plate thickness
Thread Content
Is the thickness specified in Table 3 of GB150.2 the nominal thickness or the thickness of the steel plate as supplied? For Q345R steel plates with a nominal thickness of 30 mm, is ultrasonic testing required when they are used for shells?
The new version of the fixed-volume regulations stipulates that, under certain conditions, ultrasonic testing must be performed on each piece individually
Supervision is needed; this kind of shifting issue is the most annoying and also the most prone to errors.
