VX Exchanger RT is a complete system designed for radiographic testing of tube to tube-sheet welded joints with the only one-sided access from the tube-sheet side.  VX Exchanger RT digital system fully replaces the classic film-based method.  It allows the inspection to be undertaken with unparalleled increase of performance in comparison to legacy technique and can be used for metallic materials up to tube diameter of about 48 mm.

Advantages

VX Exchanger RT system is ready to use
VX Exchanger RT system is ready to use
  • significant cost and manpower savings
    • no consumables (no film purchase and preparation, no development, no chemistry necessary)
    • faster testing: fast acquisition time per joint (<10s) and shorter total inspection time (1/10 of conventional testing)
  • handling
    • inspection results available instantly
    • computer-aided (supporting) evaluation
    • no isotopes storage and transportation (no hazardous material)
    • smaller restricted access area (2x2 m² is sufficient), thus no disturbance of production processes at manufactoring site
    • fully digital evaluation and documentation
  • wider application area and testing up to higher requirements due to
    • increased sensitivity: 0.2 mm pore diameter detectable in Ti and at least 0.3 mm in low-carbon steel detectable, whereas with Ir192 smaller than 0.8 mm cannot be seen
    • feasibility of 100% testing (minor added costs, feasible inspection time)
  • welding process optimization, due to immediate evaluation of results on-site

VX Exchanger RT is powered by the ISee! Professional software and features, besides digital image acquisition and computer-aided control of the X-ray source, task-specific image inhancements, efficient image evaluation and data management.

The system consists of:

  • high efficiency cutom-made digital detector with 100 micrometer spatial resolution
  • pen anode metal-ceramic X-ray source
  • high-voltage generator
  • computer (notebook or stationary PC) with (optional) high quality evaluation monitor
  • ISee! Professional software with add-ons for controlling of the X-ray source and digital detector, image processing and evaluation, report generation and archiving (optional)
  • transportation case (which can accomodate all system components and fits itseft in a car trunk)
