Pipeline and heat exchanger testing

The advantage of this eddy current method is that high test performance can be achieved and stored in a short time.

Quality inspection with high throughput

Pipelines of energy and chemical plants are tested from the inside using eddy current probes. Whether in a boiler with ferritic pipes or in heat exchangers made of stainless steel, aluminium or copper, with our eddy current probes we inspect several hundred pipes per shift and can thus detect damage. In the case of non-ferritic pipes with a wall thickness of up to 5 mm, it is possible to distinguish between internal and external damage. In the case of heat exchangers, both the long tubes (and U tubes) and the roll-in areas can be tested. This is where the advantage of eddy current testing lies in the high testing performance and the fact that (non-conductive) deposits and/or coatings in the tube do not significantly restrict testing.

A detailed documentation gives information about the overall condition, as well as about each individual pipe. The measurement data is stored so that the evaluation can be traced at any time. This is a means of preventing standstills. We test pipes with large diameters, such as water pipes with diameters of up to 1600 mm and internal coatings of up to 10 mm, with pigging systems.

Error detections:

  • Corrosion damages
  • Large area erosion
  • Vibration damage, e.g. rattling damage
  • Dezincification
  • Conductivity changes
  • Structural changes due to heat or chemical influences
