I ndustry N ews Rise in production quality at Huaigang Huaigang Special Steel Co Ltd, a company of the Chinese Jiangsu Shagang Group, has placed an order with the German company Friedrich Kocks GmbH & Co KG in Hilden for the modernisation of their existing rod and SWAGELINING Limited specialises in the control and prevention of internal corrosion in new and existing pipelines. The company uses polymer lining technologies developed from a concept originally created by British Gas and United Utilities. The company’s official Australian partner, ITS Trenchless, has announced that it has secured a $4mn contract with South Australia’s water utility corporation, SA Water, to perform the largest polymer lining drinking water project to be undertaken in Australia. The £2.5mn contract, which is now underway, will take approximately four months to complete. The project involves lining 4,630m of existing 24" nominal diameter water main that runs beneath one of the busiest roads in Adelaide. PROLIFIQUE Rolls Pvt Ltd is a roll and tooling manufacturing company based in Northern India, with experience of manufacturing rolls over a period of 15 years. Around two years ago the company’s brand name was changed to Prolifique Rolls when new management took charge of the manufacturing facility. The company provides quick delivery and uses high quality material imported from Europe. Over the last two years the company has received numerous orders

bar mill. The target of this modernisation, which will be reached to a high degree by implementing a Kocks 3-roll reducing and sizing block, is to raise the product quality in order to strengthen the market position. The new reducing and sizing block is dimensionedtooperatewithfour3-rollstands and a nominal roll diameter of 215mm. It will be implemented as finishing block in the 600,000 t/a rolling mill behind an existing ten-year-old Danieli Morgårdshammar roughing and intermediate mill consisting of 18 2-high HV stands. The 3-roll block will roll straight bars from 13mm Ø to 22mm Ø onto the cooling bed. The RSB allows rolling out of only one pass series from the roughing and intermediate mill and thus significantly reduces the number of required feeders. Stephen Barnes, managing director at Swagelining Limited said, “Our patented Swagelining™ technology was originally developed specifically for rehabilitating utility pipes in challenging locations, such as beneath busy roads. “The Swagelining system is highly versatile with liner thickness varying from project to project. In the case of the Adelaide project a 594mm polyethylene (PE) 100 liner with a wall thickness of 56mm is being used to meet the client’s requirement for a liner with full structural capability. “This is in contrast to another water project recently completed in the UK where the requirement was for a thin semi-structural liner, which saw us install a 1,016mm PE100 liner with a wall thickness of only 20mm.” Swagelining Limited’s from reputed international firms based all over Europe, North America, Africa and South East Asia. Its manufacturing facility uses the latest CNC turning centres, imported from Germany, to deliver high quality and precision end products that are used in various sectors, including auto and bicycle industry, construction, engineering, petroleum, boiler and heat exchanger and conveyor industry. Prolifique Rolls recently received a large order of approximately $3.5 million to

Any desired finished dimension of the complete dimensional range can be produced in any desired sequence with a minimum number of roll sets and just a few stand changes. The Kocks scope of supply includes the 3-roll reducing and sizing block with automatic quick stand changing system, remotely controlled adjustment of passes and guides as well as the roll shop equipment with quick roll change and CAPAS – the computer aided system for accurate adjustment of rolls and roller guides of 3-roll stands.

Mr Barnes continued, “Unlike open trenching methods, Swagelining has minimum impact not only on the community, but offers significant environmental benefits as well. These include a reduction in raw material usage, less waste to be disposed of, lower noise levels, less dust, and the ability to complete the project within a short time frame.” Swagelining Limited – UK Email: enquiries@swagelining.com Website: www.swagelining.com manufacture more than 12,000 rolls for an Indian OEM for one of the largest steel producers in the country, currently on a massive expansion.
