FAQs From Masterclass

We're helping service providers to invest in the quality of their measurements and the safety of their inspectors. Our High-Temperature Masterclass equips NDT inspection teams with the skills they need to meet the high-temperature demands of their customers for on-stream asset integrity data. Having provided several courses to date, we thought it would be helpful to share some of the questions and answers that are frequently discussed.


I haven't had any high-temperature training in the past. Can I still attend?

Yes! There is a gap in most of the inspector's and technician's knowledge regarding high temperatures because it is not covered in the primary syllabus of conventional level 1 / 2 Ultrasonic Testing courses.


How much training is involved?

The course is delivered with your busy schedules in mind and takes only half a day, including a practical session. The training is split between theory and practical, with lots of discussion in between with lots of time for questions, which we actively encourage! It's the perfect time to ask an experienced member of our team!


How hot can the probe get?

Ionix inspection probes are accurate high-temperature probes. They can be left in an asset ≥ 350°C / 660 °F indefinitely, without cooling, which is excellent for corrosion mapping as you only need one probe. A 50% 20s duty cycle (20s on, 20s off) should be used for temperatures from 350 °C / 660 °F to 500 °C / 932 °F, and we can offer specific advice if you want to go even hotter!


Do my procedures need to be altered to include high-temperature measurements?

All training will be tailored to your current procedures for inspection; it's an excellent opportunity to go through processes in detail; it's usually the case that high-temperature inspection is already covered.


Can I use my current flaw detector and or thickness gauge?

The practical part of the training is showing you how to work with your current ultrasonic gauges to make accurate and repeatable measurements at high temperatures. Ionix inspection probes are designed to be compatible with industry-standard equipment, including Flaw detectors and Thickness gauges and cables.


How do I set my zero offsets at high temperatures?

Due to the unique design of Ionix probes, before we zero the probe offset, we teach you to heat the search to the asset's temperature; once we have thermal stability, we can set an accurate zero, which will be stable for multiple thickness measurements. You will be shown how to set the offset in line with your procedures to give the most robust measures. This is covered in detail in the course.




How do I adjust my measurement for the effect of temperature?

You will be introduced to the different methods used to manually compensate for the effect of temperature on the sound of sound within a material which affects the thickness. We will also show you how to use your UT thickness gauge/ flaw detector's automatic features. The class will also cover other sources of error introduced when measuring high temperatures.


Won't my couplant dry out and smoke at high temperatures?

Regular couplant would. The correct couplant is vital when taking high-temperature measurements; the course details selecting the right coupling for the application.


What type of probes is the HS582i?

Dual element 5 MHz 8mm dia.

Dual element probes are best suited for detecting a more comprehensive range of damage mechanisms, from uniform wall loss to pitting, and are preferred for high-temperature inspection.

Ionix also offers 5MHz 12mm probes for scanning and 2.5MHz 12mm probes for thick or cast samples.


Does Ionix provide other inspection equipment?

Ionix provides dual probes for thickness, corrosion and erosion surveys and high-temperature TOFD probes for weld inspection. Ionix also provides installed probes and automated data collection systems for monitoring.
