Questions regarding pipeline flaw detection
Thread Content
In my case, the construction party doesn’t want to carry out RT testing and wants to switch to UT testing. What’s going on? Is RT testing more complex than UT testing?
One is a ray, the other is ultrasound; the detection devices are different, and so are the detection costs
Generally, RT is used; isn’t the inspection effectiveness of RT for pipes not as good as that of UT?
RT is better for wall thicknesses less than 10 mm, while UT is better for wall thicknesses greater than 10 mm; both are used for detecting weld defects.
Pipe wall thicknesses of 6 MM or less cannot be inspected using UT
