Pipe Deformation Analysis (PDA)

Our deformation analysis is based on:

  1. Analysing Caliper Data
  2. Analysing Deviation
  3. Allowable Free tool flexible bending. Bending in 0.5° per 10m corresponds to bending in 80mm

Please see examples below.

Fig 2. Casing ID is 118.4mm.
95mm OD Tool of 12 m length with allowable bending 0.5degrees per 10m could come through the Casing.

Fig 15. We can detect deformation of any calibre. Depending on the AER severity class (1 through 4) – the consequences of a deformed pipe can lead to serious environment contaminations and production loss.
