SCITEQ X-ACT TwinEye (X-ACT TwinEye 40, 63, 75, 110, and 200)

Multi-layer or single layer pipe on-line measurement. SCITEQ-X-ACT TwinEye uses advanced x-ray scanning technology with two projections (X-ray arrays) to measure single layer or multi-layer pipes on-line. The use of two X-ray arrays secures a fast and accurate dimensional single and multi layer measurement independent of the pipe position through the scanner. The unique and patented technique provides accurate measurement of individual layer thicknesses, densities and ovality of most multi-layer pipe constructions.

The measurement technique is non-destructive and completely temperature independent. The unit can be used on or off line; it can even be moved from one line to another without having to stop the extrusion process thanks to its innovative mechanical construction. The X-ACT TwinEye offers numerous advantages among others:

  • Accuracy and Precision - highly accurate and precise on-line quality control measurement
  • Efficiency - easy to use, no calibration, immediate setup
  • Productivity - increase meters of quality pipe per time unit
  • Continuous improvement - optimize material consumption


  • absolute measurement
  • no calibration
  • material savings
  • non-temperature dependant
  • patented design
  • pipe ovality
  • automatic calibration

Return on Investment:

When investing in process control equipment like the X-ACT system or our adjustable calibrating sleeves, SCITEQ offers to do Return on Investment calculations on behalf of our customers. We assist in measuring the profitability of the investment and make a calculation based on key factors to clarify what the expected ROI will be. These calculations are typically based on real figures of extruder output, knowledge of material price, and tolerance values. Often it turns out that payback time is actually less than 1 year.
