Tubular heat exchangers play a very important role in several sensitive processes. Their use is vital in industries like power and chemical and refining. The shell and tube side are made to be kept separate at all times, so a tube leak can have catastrophic consequences if left unattended. From ecological consequences to lack of efficiency, earnings, and in the worst case loss of life.
An assortment of non-destructive testing methods is developed to help prevent these situations from happening. Before only nuclear power stations would perform routine inspection because of the large costs involved. However, because of efficiencies in manufacturing prices have come down considerably and non-destructive testing methods are now used widely within the gas and oil industries.

RFET (Remote Field Electromagnetic Technique) is one of the principal techniques used for carbon steel and other metals that are magnetic. Inspections utilizing RFET are conducted by the tube’s ID (Inner Diameter) and utilizes a multichannel strategy. RFET has the benefit of requiring little preparation, being quick to do and using a high reliability and policy.
Another important technology utilized is ECT (Eddy Current Technique). Eddy Current is used for non-conductive alloys like stainless steels, copper nickels, titanium, and brass. Again testing is conducted by the ID (Inner Diameter) of the tubes. Eddy currently is similar to RFET for non-magnetic alloys, it supplies lots of the very same advantages and is normally the go-to technologies for fast cost-effective review.
