Flexible borescope would be one method.

Ask the hydro-jetter to put the water jet into a few tubes rendomly. Boroscope would make you scared.

Dear MrPSK
This is because of low quality cooling water entering the rubes, which leads to choking and fouling

Hopefully you resolved the issue i think as you posted this question on Feb-2021.
As per your question understood that it is Straight tube (Not an U-Tube), so better u can go for Hydro-Jet cleaning. Also if you need to ensure the integrity of tubes u can choose either Eddy Current or IRIS Inspection.

The inspection must be during cleaning operation. Take photos before and after cleaning.
