Platform Heater Tube Inspection
I am in search of proven NDT techniques to test/inspect tubes in platform heater coils. These vertically orientated coils are "U" shaped with two headers (inlet/outlet) connected to each end. The horizontal orientated Headers are approximately 30' long with around 30 "U" shaped coils distributed down the axis. The material is susceptible to creep damage. Any recommendations on inspection techniques and experiences would be appreciated.
