SCC in carbon steel and inconel pipes by O2 penetration

I am doing a research in strees corrosion cracking
in carbon steel and inconel pipes which transport
oxygen as part of a reaction in a petrochemical plant.
The pipes are of 3" to 4" in internal diameter and 370 mils
of thickness aprox. The samples I look at, have internal
cracks growing from the inside diameter to the outside
of the pipe. As I undestood, there is a flame burning
from the outside of the pipe and the oxygen is flowing
in the inside of the pipe. I do Ultrasonic inspection,
using a single straight transducer 5.0 MHz and compare
the backwall echo to find out the loss of signal and
continue with calculus of the degradation of the pipe.
Now, I need further information of the chemical reaction
of this subject and any other means of the UT inspection.
Any advice will be of great help. Thank you

Conformable wedge transducer

The conformability is obtained with a flexible membrane filled with water between the transducer and
...
the inspected component. The coupling between the membrane and the component requires a small quantity of water or couplant. The conformable wedge combines the acoustic performance of immersion technique with good coupling and low attenuation.
