Solution for flexibility of pipe production EVER-increasing requirements for pipe tolerances set virtually impossible tasks for more and more manufacturers, resulting in serious economic risks for the companies. Special pipes for the gas and oil industry, with a wall thickness above one inch and increasing for clad pipes as well, are subject to such sophisticated tolerance requirements that only a few pipe manufacturers are able to match. pipe manufacturers have to deal with rolling flaws, pinch points and severe welding problems when pre-bending with rolls, the combined Graebener crimping technology ensures a minimum of straight pipe ends for a perfect joining result even with the most demanding materials.

Both plate edges are pre-bent simultaneously throughout the entire plate length in a step-by-step process – without any pinch points which pose serious problems for the operators of roll pre-bending machines when it comes to the final acceptance by their customer. Thanks to specially arranged cylinder systems, increased tolerance requirements are no longer a problem. A movable tool table gives users of the new technology a quick change between the crimping tool and the calibration, straightening and bending tool. “Future oriented pipe production lines must cover multiple work steps reliably. Only in this way we can we ensure the highest flexibility for our customers as well as a quick return on investment,” said Dieter Kapp, managing director of Graebener. Graebener Maschinentechnik will present more information and technical details on the new production line at Tube in Düsseldorf. This year the machine builder will put the spotlight on production concepts for economic and flexible pipe production, such

Many companies are lacking suitable production machines that can meet these requirements efficiently, reliably and economically. The German machine builder Graebener has specialised for years in the task of preparing pipe manufacturers worldwide for exactly these challenges. The latest response to the current trends of pipe production is a combination of proven machine concepts – a combined calibration, straightening, bending and crimping press. It is a four-in-one design – crimp plates, calibrate pipes, straighten pipes and bend pipes using only one machine. Especially designed for thick-walled materials and clad pipes with small and rapidly changing lot sizes, the newly developed technology offers a number of advantages. During the crimping process, conventional post-bending presses and roll pre-bending machines quickly meet technological limits. While numerous

Inspection, measuring and testing CONTRÔLE Mesure Systèmes (CMS), a specialist in non-destructive testing methods, offers a large range of NDT equipment, especially for tube inspection, on- or off-line, in ferrous or non-ferrous metals. These rotating heads can be combined with other CMS equipment, RotoUTscan ultrasonic rotating head for inspection of steel alloy bars

such as magnetising units, rotating systems or support coils, and can be installed together in a strong control bench including centring devices. Supervision software allows the display of combined signals (UT/ET) and creation of inspection reports that can be used as control evidence for quality services and customers during any future scans. Stored data can be recalled for analysis and quality treatment. All the systems meet quality standards such as API, ASTM and DIN.

The two main CMS products are RotoETscan eddy current rotating heads for tube inspection in a 1 to 220mm diameter range, for surface, subsurface and punctual flaws detec- tion; and RotoUTscan ultrasonic rotat- ing heads for tube/bar inspection in stainless steel, titanium, zirconium, or carbon steel (6 to 250mm diameter range), for longitudinal and transversal defect detection, thickness measure- ment, OD, ID and ovalisation.
