Copper tubes for ACR and plumbing Nissan Copper Limited is a manufacturer of copper and copper alloy pipes, tubes, rods and flats. The company has complete in-house facilities for melting, casting, extrusion, pilgering, cold drawing, finishing and inspection. As a part of its expansion programme, Nissan is setting up a project to manufacture copper tubes for ACR and plumbing applications. The company will be producing plain and inner grooved copper tubes in straight lengths, pancake coils and LWCs, with ‘cast and roll’ technology. The new plant is under commissioning and the commercial production was scheduled to commence in January 2011. The installed capacity will be 1,000 MT per month. Butting’s range of manufacturing capabilities includes a versatile and sophisticated laser processing centre. A major customer in the petro-chemical sector is taking advantage of this; the family owned company is manufacturing ready-to-install piping components, which the customer will later use in a reformer. The pipes, in sizes 174 x 3mm, are continuously manufactured from coils, using thematerials Alloy 800HT and Alloy 602CA. The laser cutting equipment is used as part of the subsequent processing to produce special 3D profile cuts. Ceramic granulate catalysts are later placed in the completed piping components, and process gas going through will then escape via the laser- cut profiles as defined. The piping components will have a total component length of 9,952mm and are manufactured by the internal diameter, with a tolerance of ±0.5mm and a simultaneous ovality of ±0.85mm

Nissan supplies many types of copper tubing

The company has plans to expand its existing tube plant with the installation of a proposed new imported extrusion press and pilger mill with sophisticated downstream machinery to produce high value copper alloy products, such as tubes, rods, sections and profiles. The alloys used will include 70/30 and 90/10 cupro nickel, cunifer, aluminium brassandadmiraltybrass, variousbronze

alloys, tellurium copper, chromium copper and sulphur copper. Nissan Copper also has plans to manufacture cupro nickel pancake coils, copper capillary tubes for ACR applications and PVC coated copper tubes for plumbing and gas piping applications.

Pipe manufacturing, 3D laser profiles and circumferential welding, from a single source

maximum. All the welding seams are 100 per cent FE-tested. Previously, these pipes were processed further by three other companies after being manufactured by Butting, before the end-product reached the customer ready to be installed. Thanks to its

expanded laser capacities, Butting can now perform all the subsequent work processes in-house. H Butting GmbH & Co KG – Germany info@butting.de www.butting.de
