CIPP Calibration and Deformation Measurement
Engineering rules and standards consider caliber measurement (determination of the inner diameter ID) as an important precondition before performing any pipeline rehabilitation, i.e. inserting a new angular flexible tube into the old pipe.
The measurements should be made continuously with measuring distances ≤5cm.
The accuracy of the devices is ≤1mm. The device measuring accuracy is certified by the certification body TÜV.
The measuring results are documented graphically and arithmetically in a protocol and finally handed over to the contracting body.
