TesTex provides inspection services for all types of tubular heat exchangers including Air Cooler-Fin/Fans. We do this work on scheduled outages as well as emergency situations. Unlike most other NDT companies, Heat Exchanger Inspection is one of TesTex’s specialties. So when you call us with an immediate need, you know you will get a field service crew who is trained in tubing inspections; when you contact other NDT firms that do all NDT disciplines, and you have an immediate need, you will usually get someone who happens to be “available” but does not have the proper training or experience in Heat Exchanger Inspections – however, they may be the best UT technician in the world. When you have dozens or even hundreds of Heat Exchangers to inspect, rest assured knowing that TesTex can provide over (40) Heat Exchanger Inspection teams at any given time.

For carbon steel and other magnetic metals, we use the TesTex Eagle Plus Single and Multichannel Remote Field Electromagnetic Technique (RFET) System.

For non-magnetic metals such as Stainless Steels, Copper Nickels, Brass, Titanium, etc. we use the TesTex TX 4400 Multifrequency/Multichannel Eddy Current System.

Because TesTex manufactures it’s own RFET and ECT equipment, we are never short of the necessary test equipment to handle your needs; this also means that each of our inspection teams come prepared with ample back-up/redundant equipment. We also manufacture all of our own probes and calibration standards. Therefore, we can respond to emergency needs better than any other Heat Exchanger Inspection company.

In addition to the inspections listed above, we also provide IRIS Ultrasonic Tube Inspections as a back-up or as the primary technique. We also offer Video Borescoping services.

Whether you have one heat exchanger, or several hundred heat exchangers, we are set up to support your inspection needs.
