and bars, the latter recording a big order with delivery of seven machines to a new pipe mill in Saudi Arabia. Reika’s RingSaw ® Avantgarde has the potential to become tomorrow’s classic: detailed test runs together with leading manufacturers of roller bearings confirmed and even exceeded remarkable savings by that new technology saw head that orbits the stationary workpiece: cost savings of 50 to 80 per cent, compared to conventional carbide saws at 30 to 60 percent faster capacity, leading to quickly redeemed investment. Meanwhile, new test runs with bars, smaller (40mm diameter) and bigger (600mm diameter) tubes, reported impressive results. Everybody at Reika is really proud of this machine, performing almost every day since its launch at the Tube Show in Düsseldorf in April 2010. But the company, based in Hagen, North Rine Westphalia, Germany, is still anxious to keep the tool technology up to date. High-tech tools are constantly being developed to optimise the outstanding results. Continous development is also the KeywordatGräbenerMaschinentechnik. AmongHydroformingandhot-stamping- presses and plate edge milling machine for manufacture of ship deck sections, there is a particular attention to machine tools for manufacture of longitudinal welded pipes. Milling machines, pipe forming presses, 3- and 4-roll bending machines, post-bending presses, continuous root tacking machines, end facing machines and so on – all machines will be updated to the latest technological standards. The most recent example is Gräbener’s pipe forming press delivered to a pipe mill in Malaysia, which is among the fastest in the world. Gräbener engineers and technicians reduced the real pipe bending time to three minutes, an outstanding proof for Gräbener Group performance and success.

The inventor of the original Big Bore Type BB chuck offers a large product portfolio to cover all applications from standard API or premium pipe to fully automatic machining of couplings in one operation. Open centre chucks up to 560mm through hole for pipe threading and hydraulic indexing chucks for couplings up to approximately 18" are now standardised. Straight or bent pipe can be clamped for threading by utilising either self centre or compensating jaw chucks. The innovative Big Bore Type BB-FZA 6 jaw sequence chuck, with three integrated centring jaws and three compensating clamping jaws incorporated in the same chuck body, allows a fully automatic clamping sequence for pipe of any quality. Associated couplings can be machined in only one set up by using the new SMW-Autoblok hydraulic ring indexing chuck Type SF-RAZ. Cutting the thread of both sides of the coupling in one set up ensures concentricity and quality. Robust design with long lifetime and long service intervals minimise machine downtime, and quick clamping cycles, large jaw strokes and high gripping force ensure safe and economical clamping of all OCTG products. Various sizes of each chuck model can be supplied as a standard, so the need for expensive special chucks with long delivery times is eliminated. turnkey solutions and service to improve the productivity and the product quality of pipe plants. The company’s new catalogue, ‘Chucks for Oil Country Tubular Goods’, is available now, on request. SMW-Autoblok offers
