Hi,
I like to know which NDT method is the best among the following methods for reformer tube inspection:
1.Ultrasonic attenuation
2.Eddy current
3.Laser profilometry
What are the limitations of these methods,if any.
Thanks.

Reformer tubes normally used in the refining, petrochemical and fertilizer industries are manufactured by the centrifugal casting process and heat-resistant austenitic alloys such as HK -40, HP-40, and HP -Niobium modified materials. A design life of 100,000 operating hours has been the normal time-based criteria for considering retirement of tubes.
