power plants, shipbuilding and repairs, petroleum refineries, sugar plants, defence establishments, and air conditioning and refrigeration. The product range includes tube and pipe manufactured from copper, capillary, cupro- nickel, admiralty brass, aluminium brass and other brasses, together with bare, low fin and U-bend tubes. Other products include copper-alloy rods, profiles and alloys such as aluminium and manganese bronze, naval brass, cadmium and tellurium copper. The company, which exports to all developed countries, has won 11 Indian export excellence awards in the last 13 years.

Historically, these tube cutting figures were unpredictable even with 100-800 cuts. These results have been verified at one customer in the mid-USA, saving in excess of US$1mn on their tube mill from the actual scrap steel tube produced. The cost of new blades and sharpening has therefore been reduced by more than 400 per cent. Total cost reductions in one tube mill line approached US$1.4mn per annum. In addition to these cost saving advances, New-Form Tools has developed a patented quick change blade/jaw system that dramatically reduces downtime in tube shearing. The New-Form quick change tool systems can now be adapted to fit most existing tube-shear cutting machines and can transform production lines into higher profit work centres. Tool package changes that would total up to 60 minutes have been reduced to as little as 60 seconds. Nexans Deutschland Industries GmbH & Co KG develops and designs the Uniwema ® 650 welding machine, which is used to manufacture corrugated stainless steel pipes up to an OD of 650mm and a wall thickness of 3mm. Prior to this recent development, the Uniwema machine had been limited to an OD of 400mm. New solutions for today’s onshore and offshore LNG (liquefied natural gas) transfer and terminal applications are provided by flexible stainless steel pipes that are vacuum-insulated with an outer diameter of up to 16". This product is important to the environmental and safety aspects that play the most important role in the increasingly sensitive LNG market. The well-proven technology of the split clamp caterpillar capstan, in combination with Uniwema corrugation technology, will be used for this world’s largest continuous forming, welding and corrugating machine. Nexans is therefore in a position to deliver any corrugated pipe system up to an ID of 600mm with any length. This depends on transportation restrictions, which usually specify a typical length of pipe section from 55m to 350m. Nexans Germany 9C41 Website : www.newformtools.com

The drive system of the split clamp caterpillar capstan is based on a hydraulic system, with the electrically driven corrugation unit synchronised to the capstan speed. The welding is performed through the company’s patented and ASME approved Polyarc process. The unique Uniwema technology is claimed to be the only technology capable of continuously producing 16" and 20" flexible metal pipes. Onshore and offshore LNG terminals are vital as they prevent excess- gas burning of natural gas. › The Uniwema ® 650 welding machine is designed for LNG stainless steel pipe

New-Form Tools Ltd Canada

New-Form Tools has developed speciality blades and cutting systems for high tensile and high strength materials including stainless steels and exotic metal tubing. The titanium coated shear blades are impact resistant and wear resistant. Those that have struggled with sawing and shearing can now depend on consistent saw quality cuts in varying size and wall thickness. Unpredictability in blade life can be avoided as these products guarantee long life and high quality cuts far beyond that of regular sawing and shearing of high strength steel tubing. Examples from users of these shear blades show that 5,000-11,000 cuts are possible in difficult high strength tubing with 6½" diameter and 0.179 wall thickness. fi New-Form has developed a patented quick change blade/jaw system
