Straightening

Straightening of oil and gas tubes TUBES, square bars and profiles, which were previously straightened almost exclusively through the rolling process or by simple manual presses, can now be precision straightened to ensure tight linearity tolerances. The Galdabini Gantry heavy-duty machine is designed for straightening long raw tubes and bars, forged or finished. Workpiece measurement takes place by continuous scanning (laser), which allows reading and reconstruction of the actual deformation curve. The aim of reducing longitudinal dimensions to the minimum is achieved, maintaining machine frame stability and flexibility of use. The machine is electromechanically or hydraulically controlled, depending on the tonnage. Measuring before and after

Heavy-duty automatic straightening machines have improved through the use of sophisticated kinematics, actuators and electronics. Applications in fields such as energy, oil and gas, steel mills and hydraulics require processes that guarantee high quality finished products. For example, in the oil and gas and nuclear fields the increasingly stringent international API guidelines and recent events have made quality standards of pipes for these applications among the most rigorous in the world.

straightening allows full traceability of the product, with an important impact on the quality of the production cycle. Easy maintenance is assured by diagnosis and maintenance messenger systems for the remote control of customer service.

Fully automatic straightening is fast and optimises machine parameters, in addition to controlling workpiece deformation (absolute and linearity error). The advantage of this process is the straightness results over the entire length, certified and repeatable measurements and high productivity of the system, especially when operating 24 hours a day, equipped with loading/ unloading units.

the energy field (nuclear) and heat exchangers. The Faspar slitting lines can process grade 1 and 2 coils, VT1-0 up to 10 tons, at line speeds up to 200m/min, and in thickness from 0.4 to 2.5mm, in order to produce strips with width from 35 to 200mm, suitable for the tube mill lines and final output tube diameter. Olimpia 80 tube mills lines can process tubes with outside diameters from 12 to 60.3mm, and thickness from 0.4 to

FASPAR, a specialist in coil processing equipment, and Olimpia 80, an expert in systems and equipment for welded tubes, have shared their experience and core business to ensure the quality of strip products at the entry of tube mills. This operation can be underestimated, but it is important in order to fully exploit the capacity of the tube mill. Faspar has been a producer of turnkey equipment for the processing of metal coils since 1966. Its main product range includes slitting lines; levelling, straightening and cut-to- length lines (with feeder, rotary shear or flying shear); surface finishing lines; feeding and pressing/punching/bending lines; and tension/stretch levelling lines. Olimpia 80 Srl has specialised in the engineering and manufacture of systems and equipment for welded tubes since 1980. The main product range of Olimpia 80 consists of complete tube mills and components. Faspar and Olimpia 80 recently put into operation one slitting line and two tube mills, positioned side by side, in a Ukrainian plant of one of the world’s largest titanium producers. The final use of these titanium tubes is in
