NDE Options for 700 Deg. F

I want to have a nondestructive evaluation for surface cracks performed in carbon steel fittings at a service temperature of 650 - 700 Deg. F. I understand that use of liquid penetrant or magnetic particle methods would require a shutdown.

A local inspection firm is investigating use of high temperature probes for eddy current method.

Are there other NDE methods to consider for this application? Are there any personal experiences with trying to accomplish this type of evaluation?
