Brushes for removing the coating of tubes LESSMAN, Germany, makes wire brushes for industrial applications like de-burring of working components or cleaning or structuring surfaces of materials and removing the coating of tubes. The external surface of steel pipelines is often coated with epoxy resin and PE or PP layers. These protect the tube from corrosion but must be removed at the tube ends to enable the welding procedure to take place when the tubes are put together. Usually several rings of knotted wire brushes are mounted together to get one massive block of wheel brushes. Diameter of the brush, wire thickness and the overall shape of the brush are defined by the sizes of the tube, the material of the layers and the cut back machine in use. The company offers brushes up to the diameter of 500mm, filled with hard drawn high tensile wire. Most of the brushes are made-to-order, as the individual applications often vary. Beside these cut back brushes, Lessmann offers various special tools for the pipeline industry like brushes for cleaning weld seams or brushes for pigs to clean the inside of tubes. Lessmann GmbH – Germany Fax : +49 9082 70778 Torlon PAI shapes are available in extruded, injectionmoulded and compressionmoulded grades, for a range of highly demanding applications in various industries, especially the aerospace, chemical processing, energy and semiconductor sectors. Quadrant Engineering Plastic Products – Switzerland Email : sigrid.dopfer@qplas.com Website : www.quadrantplastics.com Torlon PAI also displays high creep resistance and inherent low flammability, as well as resistance against high energy radiation (gamma- and X-rays).

QUADRANT EPP has launched www. designwithtorlon.com, a multimedia website that provides information to engineers, designers and machinists on the material properties and advantages of the company’s machinable Torlon ® PAI shapes. In addition to standard material information such as product specifications, basic application information and downloadable documentation, the new site also features specially commissioned video elements that hope to increase the site’s usefulness for the design community. Video segments cover topics such as saw cutting, turning, milling and fly-cutting. Site visitors can see first hand how these processes are performed in Quadrant’s Technical Centres. The processes demonstrated address many frequently asked questions about designing parts with Torlon PAI and many other advanced engineering plastics. In addition to the video segments on material fabrication and machining

procedures, Quadrant has introduced a newly commissioned series of video shorts modelled on a US talk show format that address design and performance concepts. These segments are grouped in the site’s Vodcast area and are intended to be light- hearted, entertaining and informative. The show can be subscribed to as an RSS feed by visitors who want to stay connected to new updates from the programme. The primary aim of the site is to illustrate the material properties and performance advantages of Torlon PAI when compared to machinable polyimide materials. The versatile performance benefits Torlon PAI offers at elevated temperatures, ranging from 150°C to 250°C, are not always understood in the wider materials design and engineering community. These include excellent wear and frictional performance, exceptional strength, stiffness, and dimensional stability – all of which are described in the ‘Why Torlon’ section of the site.
