Tube Inspections

While our operators were performing NDT inspections on heat exchangers and the corresponding piping, they were frequently asked whether it would be possible to additionally inspect the actual condition of the piping, focusing on erosion, corrosion, wall thickness and crack formation.

In cooperation with our German Delta Test colleagues, we are able to carry out state-of-the-art Eddy Current test services, according to customer requirements and based on respective norms and standards. We are specialised in all kinds of Eddy Current tests and provide these around the world. Tests of paramagnetic and ferromagnetic heat exchangers play a significant part in this.

We guarantee short response times from the initial enquiry through to job execution, and furthermore optimally short test times with at the same time high quality test results. Our aim is to provide information through high-quality and reliable test results, which will help you to lower your costs for maintenance and repair in the long-term.

With this reliability and our availability around the clock, we can achieve a relationship of complete trust with our customers.
