Ultrasonic technology for measuring thin pipe and tube layers

Inoex, Germany, is a specialist in measuring and control technology and process engineering in the plastic material industry. The company’s systems are finely tuned to requirements in pipe, profile, cable and film extrusion. The automotive industry and many other industrial sectors set high demands on multi-layer products. As a consequence,

the production process is complex for products such as brake hoses and floor heating pipes. Extremely thin barrier and functional layers are frequently required to provide tube and pipe with their specific mechanical and chemical properties. Conventional ultrasonic measuring techniques have measuring limits at

approximately 0.2mm. iNOEX has introduced a new technology where the bottom measuring limit is 0.05mm. Barrier layers prevent oxygen, for example, from penetrating into the pipe, or volatile components from leaving it. These layers provide products with special mechanical and chemical properties. In order to reduce cost, the aim is to make these layers as thin as possible but as thick as necessary. This can only be done when wall thickness is controlled during production. Inoex has further developed proven ultrasonic measuring principles, allowing function and barrier layers that could not be measured in the past to be precisely controlled through intelligent ultrasonic sensor technology, combined with new algorithms and digital measuring techniques. Even data of extremely thin-walled pipes can be precisely recorded, which means that high safety regulations can be adhered to and quality demands fulfilled. Ultrasonic measurement has previously been based on the determination of ultrasonic transit times inside a product. Through digitalisation the complete signal is now recorded, improving signal evaluation and further processing. The complete recording of the signal makes results highly precise, and supplies full information on the product. Inoex GmbH – Germany
