Inoex: AUREX: Accurate „inside information“ now on multi-layer foam core pipes
Measurement of foam core pipes has so far been a special challenge. Control of the functional layers has due to the specific material properties not been possible with conventional measuring equipment. Now a digital ultrasonic system is available which provides accurate „inside information” also on foam pipes.
Raw material is foamed during processing which produces small air bubbles. They enlarge the material volume and as such the wall thickness size. This saves raw material and reduces costs in a particularly important segment. However, air bubbles cause measuring problems due to the fact that they reflect ultrasonic signals. Consequently, it has so far not been possible to measure interior layers. Foam pipes are normally co-extruded pipes and it is recommendable to control the geometry of all layers in order to minimize material consumption. INOEX has now found a solution for this technical challenge: a new AUREX digital ultrasonic measuring technique….. more: KWD-globalpipe, 2008-11-25, No. 300
