Pipe manufacturing, 3D laser profiles and circumferential welding

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 the materials 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 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
