Nitrogen filled pressure vessels

Will X-rays have any effect on pressurized nitrogen in a pressure vessel. Mainly, can it increase the temperature of the nitrogen and increase the pressure? I do not think that it will but I have been asked this question by my client and I am now curious. He wants to send me some small spherical vessels that are pressurized to 6500 psi with nitrogen. The welds need radiographed. Any help will be appreciated.

Re: Nitrogen filled pressure vessels
Dear Fred,

I think there should not be any problem. The ionisation of nitrogen atoms/molecules that takes place will be reversed over a period of time, because it is a closed system.

The image sharpness could however be affected because of the scattering and secondary X-rays.

nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?

oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
