Heat Exchanger And Boiler Tube With Tube Sheet Mapping Eddy Current Detector
HEF-C35RFT eddy current instrument with remote field technology option is a new generation eddy current instrument. HEF-C35RFT with full-digital, multi-frequency, multi-channel is a versatile system offering a comprehensive array of electromagnetic testing techniques available on a single instrument HEF-C35RFT can be used to accurately and efficiently inspect both non-ferromagnetic and ferromagnetic tubing materials for flaws such as pitting corrosion vibrations wear steam erosion and cracking.
HEF-C35RFT combines the advanced testing capabilities of the HEF-C35RFT with a highly sensitive remote field technology option, makes the instrument an ideal solution for a broad range of tubing applications in the petroleum chemical and power generation industries. Where inspection of both non-ferromagnetic and ferromagnetic materials is required. In contrast to other ferromagnetic tubing inspection, the HEF-C35RFT provides not only a more complete --100% coverage with inner and outer surface discontinuity detection, but also thickness measurement -- in a fraction of the time.
