OverviewConcepts

Calibrating and straightening in one machine. Graebener® calibration and straightening presses are efficient and economic multi-purpose machines which offer the highest possible flexibility for the production of LSAW pipes. Welded pipes are calibrated and straightened to the set dimension in your Graebener® calibration and straightening press. The press tool is of a modular design. This way you can process various pipe diameters in this multi-purpose machine without have to use a different tool for each diameter.

We have developed our technology further following the ever increasing market requirements for flexibility of lot sizes. Our newest machine development, the combined Graebener® calibration, straightening and crimping press allows you to benefit from a patented 4in1 technology. Pre-bending respectively crimping of plates, calibration and straightening of pipes in one single machine. This concept is unmatched worldwide.

Benefit now from

  • Highest efficiency and flexibility thanks to multifunction technology (2in1 / 4in1)
  • Less and shorter changeover times thanks to modular tool structures
  • Fast tool change right next to the machine
  • Easy maintenance

Our solutions are ideally suited for a wide range of pipe dimensions.

Plate / pipe length:

up to 18 m

External pipe diameter:

up to 64" (1,624 mm)

Wall thickness:

up to 60 mm

The design of the Graebener® calibration and straightening presses is based on decades of experience in the pipe industry as well as the constant interaction and collaboration with our customers and partners. The result of this are individual customized solutions which provide you with the decisive competitive edge. The new combined Graebener® calibration, straightening and crimping press is one proof among many worldwide for this successful approach.

When designing the press, we pay special attention to offer you as machine operator the highest possible flexibility to be achieved with a multi-purpose technology. For this reason, we also designed the tool change to be fast and operator-friendly. The change is carried out right next to the machine by moving the tool sideways out of the press reinserting it after the tool change. This saves time and money.

To ensure optimum results your Graebener® machine is equipped with a controlled ram for the closing, pressing and opening of the tools. The ram cylinders are designed as controlled axes thus ensuring an acceleration without pressure peaks and a controlled deceleration.
