Techint Technologies strengthens position Techint Technologies has joined forces with Hypertherm, a key-player in India for the design and supply of industrial furnaces for the metal industry. Located in Mumbai, Hypertherm was set up in late 2001 by six technocrats with a combined furnace industry experience of more than 150 years. The company, with a reference list of more than 50 installations in India and abroad, is specialised in the thermal engineering field with renowned competences in Reheating Furnaces, Furnaces for Processing Lines, Continuous and Batch Heat Treatment Furnaces, Aluminium Furnaces, Lime and Dolomite Kilns and Kilns for Ceramics. The joint venture, named Techint Hypertherm Pvt Ltd, will continue its operations from Mumbai where they employ almost 70 people and mainly serve the Indian market.

Commissioning of the plant is scheduled for early 2008. SMS Mevac GmbH – Germany Fax : +49 211 881 4386 Cable specialist Nexans will present optimised corrugator technologies for its UNIWEMA® machines at TEKNO/Tube Arabia 2007, which takes place in Dubai from 13-16 th January 2007. UNIWEMA machines are used to manufacture smooth or corrugated tubes and cable sheaths by continuous forming and welding of metal strips. The machines process stainless steel, steel, copper or aluminium and their alloys, welding the material in the TIG (tungsten inert gas) process or using lasers. Depending on the machine model and equipment, tubes with an outer diameter of 2mm-350mm can be produced. Typical wall thicknesses for steel are between 0.1mm and 3mm.

Zwick comes out on top in universal hardness testing With its latest ZHU-topLine hardness tester, Zwick is strengthening its market lead as a supplier of premium universal hardness testing equipment. The first fully functioning prototypes were showcased at last year’s International Forum for Materials Testing in October in Ulm, Germany. These machines have test loads from 1 to 250kg (9.81 to 2452N) and went on sale at the start of the year. During the development process, special emphasis was placed on high operating and measurement convenience. As a technology leader this universal hardness tester is designed for hardness tests according to Vickers, Brinell, Rockwell, and other procedures. It has been developed especially for test laboratories/materials research, or quality assurance in industrial production. Unique features of the machine include its advanced digital zoom optics for carrying out a wide range of applications using a single lens, and ‘closed loop’ technology for automatic load application. An optional image processing system is available for fully automatic evaluation of the indentations, as are other options and modules, like a motorised turret and motorised compound table. Corrugation gives tubes or cable sheaths flexibility. A rotating disc-type tool presses helical or annular corrugations into the tube, with the shape of the corrugations varying depending on the tool, feed rate, pressure and corrugator speed. The company’s new optimised tools feature structural improvements to the corrugator head bearing, allowing the creation of deeper corrugations. Production speeds of up to 35m/min (with UNIWEMA 25) and corrugator speeds up to 6,000rpm can be achieved. The new tools can also be used to retrofit older UNIWEMA systems. With the corrugation depth, the surface per cable length increases, which improves heat dissipation and increases flexibility.

The hardness tester connects directly to Zwick’s proprietary testXpert® software resulting in a very easy to use and reliable testing system. In addition, the online language switching is extremely useful for international organisations and applications. Zwick will be introducing more hardness testers from this series up to 750 and 3000kg (7357N and 29,430N) during 2007.

And it is that technology that can also provide benefits in vehicle air conditioning systems, where shock and pressure-resistant flexible corrugated stainless steel tubes take on the task of transporting carbon dioxide, which is soon to replace conventional refrigerants.
