VX Exchanger XL 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 XL 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 and tube IDs from 7 mm to about 80 mm.

Advantages

VX Exchanger XL system is ready to use
VX Exchanger XL 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: pores down to 0.2 mm in diameter can be detected, whereas with Ir192 smaller than 0.8 mm pores usually 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 XL 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 enhancements, 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 accommodate all system components and fits inside a car trunk)
