VX Exchanger XL – the digital system for tube-to-tubesheet weld inspection

VX Exchanger XL is a complete system specifically developed for radiographic testing of tube-to-tubesheet welds where access is available only from the tubesheet side. This system is the only alternative to the classical film-based method and enables an unmatched increase in productivity while simultaneously improving image quality. VX Exchanger XL can be used for metallic materials (e.g. steel, nickel-based or titanium alloys) with internal tube diameters (ID) ranging from 7 mm to approximately 80 mm.

Advantages of inspection with VX Exchanger XL

Significant cost savings

no consumables (no film or development costs)
more efficient use of personnel
faster inspection: short image acquisition time
(approx. 10 s per weld) and a shorter overall time
(approx. 1/10 of the conventional duration)

Extended application areas and inspections with higher requirements thanks to:

increased sensitivity: detection of pores down to 0.1 mm. With the conventional inspection method using Ir-192, pores smaller than 0.8 mm are usually not detectable.
feasibility of 100% inspection coverage (with minimal inspection time – and almost no additional cost)

Handling

inspection results are available immediately
computer-assisted analysis
no radioactive isotopes required – no handling of hazardous materials
small controlled area (approx. 2 x 2 m² is sufficient) – fewer disruptions to the ongoing
production process on site
automated inspection report generation

Welding process optimisation

inspection results are available immediately

VX Exchanger XL is controlled using the ISee! Professional software, which in addition to image acquisition also provides functions for application-specific image enhancement, efficient image analysis and data management. Further information on the software can be found at:

ISee! Professional

The system consists of:

specialised digital X-ray imaging detector with a spatial resolution of 100 µm
metal-ceramic X-ray tube (rod anode)
high-voltage generator
notebook (or optionally a desktop PC with a high-quality evaluation monitor)
ISee! Professional software with modules for controlling the X-ray source and the digital detector, for image processing and analysis, and for inspection report generation and archiving (optional)
transport and storage case that accommodates all system components and can be transported in the trunk of a passenger car
