Remote Field Electromagnetic Technique (RFET) has proven to be a very reliable and dependable Nondestructive Method for evaluating general corrosion wall loss in tubular materials which includes both ferritic and austenitic materials. Up to this time quantitative measurements of corrosion wall loss was not available and RFET provide an excellent way of determining the wall losses. Details of RFET methods, the instrumentations used, the signal processing software and field examples are presented in this paper.
