Remote Field Electromagnetic Technique (RFET)
Remote Field Electromagnetic Technique (RFET) is designed to quickly and accurately inspect ferrous tubing from the I.D. TesTex has pioneered the advancement of this technique for both the inspec- tion of small diameter tubing and large diameter piping. This method is effective in detecting a variety of internal and external defects suchas general corrosion, erosion, pitting, etc.
