Heat Exchanger Inspection

Fin Fan NDT Inspection
TesTex provides scheduled and emergency inspection services for all types of tubular heat exchangers including air cooler fins and fans. Unlike most other NDT companies, heat exchanger inspection is a TesTex specialty; we build the equipment used for inspections, and all of our crews are trained on it. When you contact us with an immediate need, one of our 40 highly-trained field service crews will respond.

For carbon steel and other magnetic metals, the TesTex Eagle 2000 RFET System is deployed. It performs inspections from the ID.

For non-magnetic metals such as stainless steels, copper nickels, brass, titanium, the TesTex TX 4400 Multi-frequency/Multichannel Eddy Current System is deployed.

Because TesTex manufactures its own RFET and ECT equipment, we have the necessary test equipment available for large jobs, and each inspection team is supplied with sufficient back-up/redundant equipment to keep the work going. Because we also manufacture all of our own probes and calibration standards, we can respond to emergency needs better than any other heat exchanger inspection company.

In addition to the inspections based on our REFT and ECT equipment, we also provide IRIS Ultrasonic tube inspection and video borescoping services.

Whether you have one heat exchanger or several hundred, we have the capabilities to perform an inspection.
