cold insulation inspection

I am looking for the best method to inspect ice formation under Ammonia tanks ( double wall). the insulation is PUF with aluminum cladding ( the insulation is approx. 4" )

We been experminating with thermography but we can not establish a solid fact if ice is there or not

Re: cold insulation inspection
You may not be able to be definitive about ice build up using Thermography. Breakdowns in insulation which you could then extrapolate as being a source of icing should be detectable. Be careful that outer aluminium cladding is not heating up and masking differences. We often used to do the Thermography just after the sun went down.

Other possible approach is something like Neutron Backscatter - but access will be the problem you will probably have to work off cherry pickers.

Best methodology may be to build a mock up of the arrangement and test your technique qith Thermography. Introduce ice and see how fine your settings have to be to maintain discriminations.
