Heat Exchanger Tube Inspection Equipment
Heat exchanger tube inspection checks condenser, heat exchanger and fin fan tubes from the inside for wall thinning, pitting and cracks, without damaging them. Asia NDE supplies ETher NDE eddy current tube testing instruments and the SteelCheck flux leakage tube tester across Malaysia and Southeast Asia. We serve oil and gas and petrochemical customers, with calibration and repair support from our Subang Jaya office.
What it’s used for
- Eddy current tube testing of non-ferrous tubes in heat exchangers and condensers.
- Testing carbon steel and fin fan tubes with magnetic flux leakage.
- Telling inside (ID) defects from outside (OD) defects and measuring wall loss.
- Mapping tube sheets and producing reports for shutdown records.

Frequently asked questions
How are heat exchanger tubes inspected?
A probe is pushed through each tube from the tube sheet and pulled back at a steady speed while the instrument records the signal. Eddy current testing is used for non-ferrous tubes. Magnetic flux leakage is used for carbon steel tubes, including fin fan tubes. The results show wall loss, pitting and cracks for each tube.
Which method should I use for fin fan tubes?
Carbon steel fin fan tubes are usually tested with magnetic flux leakage (MFL), as on the SteelCheck. Unlike remote field eddy current, it is not affected by the external aluminium fins, and it can tell inside defects from outside defects.
