CRC-Evans Pipeline Equipment, USA, has announced the introduction of a mandrel designed to boost pull-cycle productivity by as much as 20 per cent. The Advantage mandrel requires only a single bending machine operator, who simply pushes a button on the control panel. The self-powered mandrel quickly and automatically finds its correct position relative to the die without a reach rod, eliminating the guesswork and safety issues that go with standard manual placement. The operator makes the pull, the pipe is advanced, and the job continues. “ Automatic centring means that the cycle times get shorter and jobs move faster, ” commented Fred Lysak, pipeline equipment division president. “ Setting the pace ahead of the welding crews, especially on long

pipelines, means that a contractor can get the pipeline bent and built faster. ” The chances of wrinkles and buckles at bends are greatly reduced, because the new mandrel’s advanced technology ensures that it is perfectly positioned for every pull, enabling accurate, quality bends every time. Since the process is completely automatic, it can be easily and quickly repeated until the bend is complete. With no reach rod involved, loading can be done from either the pin-up or stiff-back end, for greater flexibility of access, improving performance where the right of way is narrow. CRC-Evans Pipeline Equipment builds and distributes a complete line of pipeline construction equipment, including pipe bendingmachines, ditch padding equipment, pipe handling and support equipment, pipe

Long and super-slim borescopes for effective inspection

The Gradient Lens Corporation (GLC), USA, has launched a new and longer Hawkeye Pro SuperSlim borescope for easier inspection of defects in deep bores and the narrowest tubes. The scopes give a sharp, clear view of deep, very narrow bores in machined parts, fuel and hydraulic systems, castings, tubing, firearms and other products. The scopes are available in lengths of 10", 14" and 17". The long Hawkeye Pro SuperSlim borescopes have an outside diameter of 0.110" (2.8mm) allowing inspection of bores as small as 1 / 8 ". They use GLC’s patented endoGrins ® lens system, which allows them to relay images at a long distance while maintaining image quality. Users can clearly see surface finishes and defects like burrs in deep bores and cross-holes. The scopes feature a 0° direction-of-view, a 40° field-of-view, and offer a rotating 90° direction-of-view with a mirror tube attachment. “These new longer scopes offer easy inspection of internal problems in the deepest bores and microscopic holes in components like spray tips and nozzles,” said Dr Douglas S Kindred, GLC’s president. For more than 20 years, Gradient Lens Corporation has designed, engineered and manufactured precision optics and optical instruments. The company’s offerings include complete lines of Hawkeye precision borescopes, Hawkeye Blue borescopes, borescope accessories and Luxxor lighting and video visual inspection products.

Tungsten carbide dies and mandrels Agir Technologies (Mouton + Rivom), France, is a specialist in the manufacture of tungsten carbide tools for cold metal forming. These tungsten carbide dies and mandrels are manufactured in the company’s two workshops. The company’s customers manufacture tubes in

different steels and in non- ferrous metals for various applications, from smooth tubes with small dimensions (internal diameter 0.25mm, external diameter 0.33mm), to the largest tubes with an internal diameter of 200mm and external diameter of 300mm.

The most complex shapes are used for gearbox shafts or injection pipes in the automotive industry. The cooling of thermal and nuclear power plants requires specific steel pipes with helical grooved profiles that only a few companies are able to manufacture. In operation for over 80 years, Agir Technologies also manufactures adjustable dies with carbide blocks for simple profiles (square), and helical mandrels dedicated to the production of copper tubes used in air conditioners. The company has also developed a specific programme to optimise the range of best-suited dies to obtain the final required profile.
