Measurement of corrugated pipes With the X-Ray 6000 Pro C-PIPEAI, Sikora presents a system for the measurement of layer transitions in the production of corrugated pipes. By combining newly developed software, based on artificial intelligence, with an X-ray based system, a precise evaluation of the X-ray data of corrugated pipes is possible.

There are two crucial phases during the production of corrugated pipes. In the beginning of manufacturing, it must be ensured that the different layers of the pipes are concentric. This evaluation can take several minutes, or even hours, where only scrap is produced. After the start-up phase, the products must be evaluated in order to comply with predefined specifications at a certain line speed. In order to minimise the duration in which start-up scrap is produced, the manufacturers’ goal is to implement a permanent wall thickness and eccentricity measurement as early as possible in the extrusion process and to use these measuring values to control the process and enable a fast centring. Due to their outer pipe contour, the measurement of corrugated pipes can be challenging. The X-Ray 6000 Pro C-PIPEAI enables precise measurement of the hill-valley outer contour of corrugated pipes in the extrusion process. By measuring the wall thickness and eccentricity at an early stage, fast centring is ensured and start up scrap can be reduced. Sikora AG www.sikora.net Thermoplastic polyurethane for hot melts and extrusion Lubrizol Engineered Polymers has expanded its bio-based thermoplastic polyurethane (TPU) portfolio for adhesives with the addition of Pearlbond™ ECO 590 HMS TPU for hot melt adhesives (HMAs). The resin, from a renewable source, can be applied by adhesive formulators or designers in furniture, edge banding, electronics, hot melt film, textile lamination, seam tape, footwear and transportation. Pearlbond ECO 590 HMS TPU is a fast-setting solution with good adhesion properties for applications that require a toluene-free and more environmentally friendly alternative, as well as high temperature and hydrolysis resistance. It is designed for improved processability (versus previous existing solutions in HMAs) and has wide wettability. “The high thermoplasticity of this new grade, and the fact that it can be processed by extrusion, makes all the difference from previous bio-based HMA polymers available in the market,” said MariaJosep Riba, global sustainability manager for Lubrizol Engineered Polymers. ”In addition, it is a bio-based resin with high bio content – up to 59 per cent – which makes it the ideal choice going forward if you are looking for performance and carbon footprint reduction.” The expansion of bio TPU solutions, commercialised as Estane® and Pearlbond ECO TPU, supports the acceleration of Lubrizol’s global sustainability plans.
