The exchangers are currently being inspected. I don't think they will be coming out of service.
What can we expect to find using micros and looking at carbon content??
The dilution will be the reason why I'm not getting much help from the PMI Unit.
This is intriguing for me. My scope of...
The filler used is what we are trying to find out.
The corrosion is along the surface of the weld and it seems to have chewed away at patches rather than the whole weld itself.
In contrast, we have weld areas in the same exchangers where the weld has not been eaten away at all.
The goal is to...
Hi guys,
I have a few chemical analysis reports that do not match up on the Niton Gun. The welded areas were inside exchangers. The exchanger was 410ss. The tested areas were welds were in pretty bad shape. Moderate corrosion on the surface of the welds.

I have ASNT Level 2 and PCN Level 2 in DPI,MPI, UT and RT. Also an Autocad 2D Qual.
I didnt realise that Level 3's were that important. or at least not here in the UK.
From being on the tools, most guys then want to move on and become plant inspectors.
One thing I would like to do is work...
Hey all,
my apprenticeship in NDT inspection is soon coming to an end (within 12months) and I have an opportunity to further my study at college/university part time while working.
I have found myself working in material identification this last 12months and do enjoy it but most guys seem to...
How can I lock numerous layout tabs to display each of the 3 drawings I have created in the model tab?
At the moment I have to hide layers to see each of my drawings but then all 3 tabs change to the drawing currently in view.
I hope I have explained this clearly enough. Im sure it is...
I think this is 1 1/4 Chrome. The flange opposite is 1 1/4 chrome and has the same idents. Retested the flange and gave a different reading to the ones I was getting before.
Strange. I have checked the calibration on my set and its fine. Must just be one of those things. Possibly contamination...
I dont think it is a contamination issue with the equipment as I had done around 100 readings before and after this particular flange. All readings were fine except this one. Only possible contamination could be from the petroleum coke???
I tested the flange numerous times and in 2 different...
Unfortunately that's not my decision to make. What would normally happen in this instance is that the Flange will be replaced during the next TA. If, conventional NDT methods show that it is not highly corroded.
I'll go ahead and report this as a no match with the chemical analysis for the area...
Yes, all pmi procedures are carried out correctly. the surface was clean and free from contamination (as good as any other surface prep).
Contaminatation was the first thing that came to mind so i prep'd the surface even more and retested.
Cheers
Hi there guys,
This is my first post so i would like to say thanks for the extensive information available on these forums. its really interesting.
Now, I normally liike to run searches for answers but in this instance I have something quite specific I need to find out. I have an element...
