Heat Exchanger Tube Inspection

Heat exchangers, nuclear reactors, boilers and condensers are used in all fields of energy supply, such as the oil, gas and petrochemical industries. Failure of the tubing within these heat exchangers, will result in the undesirable discharge and
mixture of the contained media.

Consequences of defective heat exchanger tubing

• Loss of investment due to damage of high value plant components.
• Loss of profit due to interuption or complete breakdown of plant production.
• Increased reject rate due to a mixture of media.
• Environmental pollution.
• Loss of image.

 

Our state of the art corrosion inspection method with the eddy current technique, can help avoid costly production disturbances, by early detection of possible tube wall damage. This with the advantage of accurate documentation for further preventative maintainance.

KontrollTechnik carry out all inspections with the latest state of the art TMT eddyMax® eddy current computerised technology, which provides fast data acquisition and entire defect result documentation.
With 35 years of field experience our operators and analysts ensure a reliable and quality service to all inspection tasks undertaken, no matter how extraordinary the requirements.
