Large Dia. Line Pipe

Graebener Maschinentechnik tube calibration & straightening press

These press types serve for calibrating and straightening LSAW pipes.    The pipe is calibrated step by step.    The respective pipe section is placed into the semicircular lower tool.    Press forces and tool geometry are designed in a way that material spring-back can be compensated.    Stresses in the weld seam are reduced.

Calibration & straightening press

This type of press has been developed for calibration & straightening press LSAW pipes.   The pipe is moved through the machine and calibrated and straightended by the tool in a step-by-step process.    Press forces and tool geometry are designed so as to compensate material spring-back.
