AUREX ERS - Ultrasonic measuring system

ECCO is the efficient solution for fast pipe centering. Especially for thick-walled large pipes, with low line speeds and high mass throughput, the start-up process is difficult, time-consuming, and associated with high raw material costs. ECCO makes it possible to measure the wall thickness distribution shortly after the pipe calibration. The ultrasonic sensors, which are mounted directly behind the calibration sleeve in the vacuum tank, are pneumatically and flexibly moved up to the respective pipe geometry after line start-up and adapted to the pipe. Further advantages/features: — Significant reduction of start-up scrap — Fast pipe wall centering — Fast reaching of product specifications after product start-up — Fast detection of product variations — Uniform wall thickness distribution — Suitable for PE, PVC, and PP with an outside diameter from 200 mm (wall thickness range PE from 8 - 140 mm, wall thickness range PVC and PP from 8 - 40 mm)

The AUREX XXL is the solution for large pipes with a diameter of up to 3000 mm. The system works with 8 water-coupled ultrasonic sensors that can be pneumatically adjusted. This is possible without conversion in case of a change of dimensions. Minimum wall thickness tolerances are obtained via the downstream control loops of the weight per meter and thin point control and production is perfected. The better centering enables considerable material savings, especially for large pipes. Further advantages/features: — Production quality assurance by measuring and controlling wall thicknesses and diameter — Documentation of production — Material savings of up to 5% — Large measuring range — Proven measuring and control principles

The AUREX MK is the complete solution for pipe dimensions from 0.5 - 400 mm. It enables compliance with the specified tolerances for wall thickness, eccentricity, diameter and ovality. Thanks to the combination of high-quality electronics with innovative measuring methods, up to 7 layers from 0.02 mm wall thickness can be evaluated. In addition to the standard measurement for control and visualization of the product, the "Fast Specification Check MK/AFM" is optionally available, which allows a fast wall thickness check. Since the AUREX MK does not completely cover the pipe at the circumference, this wall thickness check can be used, for example, to detect typical thin section rings caused by jerking of the produced pipe at the entire circumference.

The AUREX AFM measuring chambers are flanged directly to the outlet of the vacuum tank. With up to 24 sensors a reliable and precise ultrasonic measurement with a centric pipe guidance is guaranteed. The measuring chambers are available for a diameter range of 63 - 630 mm. The AUREX AFM performs wall thickness and diameter measurement in parallel according to the number of sensors. Optionally, the AUREX AFM can be equipped with the "Fast Specification Check MK/AFM", which enables a fast wall thickness check. Since the AUREX AFM does not completely cover the tube at the circumference, this wall thickness check can, for example, detect typical thin section rings, which are caused by jerks of the produced tube at the entire circumference. Further advantages/features: — Large measuring range with measuring range extension — Parallel measurement of wall thickness and diameter — Very robust mechanics — Separable adapter for easier seal change
