as well as the optimised tool handling. As a result of drive optimising, further reduction in the CO 2 value can also be recorded positive by the customer. The latest generation of Reika chamfering lines operating according to API 5 L & CT standards, is used for weld and thread preparation of longitudinally welded steel tubes with a wall thickness of up to 25.4mm and a material strength of up to 900N/mm 2 . The line is equipped with a concentric and automatically adjustable three jaw clamping system as well as complete tooling systems for different API angles and geometries. Fast changeover times are achieved by the quick tool change system with integrated handling device and tool monitoring. A completely re-designed rugged high-performance spindle unit with up to 100kW continuous power ensures extreme cutting performance.

equipped with corresponding charging and discharging handling systems as well as straightness measuring devices. Allen Bradley machine controls were installed upon request of the customer, which were designed and executed by Bültmann’s in-house electrical department. The required alignment accuracy <0.2mm/m is reliably achieved, which was verified by the successful machine acceptance.

lightweight construction and in orders for straightening machines. Due to the growing demand for peeling and drawing machines, two additional tube straightening machines were recently delivered to a US customer with subsidiaries in the EU. The two machines of the type RRM 10/032 and RRM 10/150 are the supplement for the type RRM 10/350; already delivered in the past. Both machines, which cover tube diameter ranges of 4.8 to 152mm with wall thicknesses of 0.5 to 13.5mmand lengths of 5 to 13.5m, are 10-roll straighteners,
