Dear Ali,
Please have a look on my suggestions other than the earlier one and let the group members give their comments.
If new pipe is available, a small spool piece can be removed from the affected pipe and then replace with the new spool piece. you can also think about welding a bigger reinforcement pad at the affected place.

Regards,
Kuldeep Misra

The line got wasted externally because it was attached to a support creating a crevice corrosion.
Pipe is carbon steel API 5L, 10" diameter used for process gas, pressure 260 psig and temp = 90 c.
The affected area is 1" X 1"

Regards,
Ali
