EXHIBITION REVIEW | K2022
Right: The ProfilControl 7 S system automates the inspection of corrugated tubing, says Pixargus
Pixargus has upgraded its ProfilControl 7 S inline inspection system for corrugated tubing – saying that it reduces the effort of checking these pipes for flaws.
In corrugated tube extrusion, inspection systems
must deal with alternating sections of corrugated and plane structures. Certain sections may require other inspection modes – or the corrugator may engrave features into an extruded product that must not be detected as defects. For this, the updated product offers special algorithms that raise automation in quality inspection. “It is our aim to supply systems that ideally need
no setting up by the operator,” said Jürgen Philipps, managing director and head of technological development at Pixargus. As well as their characteristic corrugations,
corrugated tubing may include recurring sections with features that require special inspection. For instance, automotive customers may order sets of different corrugated tubes for the assembly of engine blocks. These tubing sets can be made in a corrugator line as a continuous product. A new algorithm in the inspection software now automatically recognises where one section within a set ends and the next one starts. If different inspection tasks apply, the algorithm ensures that the correct parameters are used in each case. This makes handling faster and simpler, even in case of a very diversified product. Corrugator dies can also engrave various markings into a product. To make sure they are not detected as defects, the system must recognise them. The software upgrade also includes a new algorithm that automatically recognises and accepts the engravings. The new sensor unit is an advance on the design
of the PC7 S Tube inspection system. Eight high- performance cameras inspect the peaks, valleys and transition areas of the corrugated structure – and can distinguish between unwanted and desired structures and features. Holes, dents, blisters, nodes, scratches and cracks are accurately detected, allowing out-of-spec production – and production costs – to be reduced. �

SABIC showcased its expertise in building and construction application at K2022 – including pipe solutions for a number of applications. “Greater urbanisation is increasing the demand for safe and secure potable water, sanitation, fluid and other critical piping above ground or below,” it said. “Our material solutions increase the performance and lifetime of pipes in infrastructure,

industrial, domestic and agricultural markets.” These include a range of both polyolefin and
PVC grades – ranging all the way up to PE100 for high pressure applications. In the domestic market, new polyolefin grades have been used for safe and cost-effective pipe systems in clean water supply, wastewater discharge, heating and cooling. Its HDPE materials have also been used in the manufacture of pipes used for pressure- and drip-irrigation. Pipes in industrial sites are often exposed to
high pressures, aggressive fluids and abrasive substances. PE100 and other grades have been developed for these types of application. Infrastructure is a key area for pipes. One
growing area is energy distribution – and here, the company has developed a custom solution for to protect underground power cable ducts. In addition, it has developed a biaxial pipe technology – offering up to 30% of material savings over existing polyolefin pipes. In addition, it boasts superior resistance to slow-crack growth, to facilitate cost-efficient trenchless installation. �

Sikora has developed the new X-Ray 6000 Pure device to measure the dimensions of single-layer tubes. The first two models – 6070 Pure and 6120 Pure
– measure tubes and hoses from 6-65mm and 10-110mm, respectively. As well as measuring single-layer tubes and
hoses, the total wall thickness of many multi-layer products can also be measured. Combined with the Ecocontrol Pure – a processor system with a 15in touchscreen display – the measured values are clearly displayed for further analysis. X-Ray 6000 Pure is cost-effective, safe and a powerful alternative to conventional technologies, says Sikora. It allows constant monitoring of wall thickness to reduce it to the minimum tolerance
