Condenser tubes make going on a common item of item within the non destructive laboratory analysis industry. They vibrancy a necessary role in many choice industries; even even though particularly process joined industries, oil and gas, refining and facility. The condenser tubes make happening the main part of the condenser, and disclose water to flow through in order to shorten steam coming into the unit.
Due to the temperate regulate, and water flowing through the tubes, they’something following a prime victim for fouling, corrosion and added defects. Non destructive examine offers many every choice technique to analyse the condition of the tubes, and each offers oscillate advantages and disadvantages depending approximately the scope of inspection required.
IRIS – Internal Rotary Inspection Technique is an ultrasonic technique that offers a highly high correctness of inspection, picking going on vis–vis little pits and defects, which delivers a high put in image. IRIS suffers from a couple of drawbacks however, and these are due to its high conclusive. The first is the eagerness, because of its tall optional accessory, it needs to be pulled through the tube slower, in order for the technician to analyse the data. It moreover requires a high level of cleanliness, in order to fabricate an image. Because the technique is based on the order of the subject of ultrasonics, it requires a fine malleability behind the tube, and because of this, intensely thorough cleaning of the tubes is required.
Eddy Current Inspection – ECT as its known is an electromagnetic technique that with than more offers a high degree of correctness. Between the two, IRIS has a slightly remote unadulterated, and would be the irregular for more necessary jobs, though eddy current is pleasant as soon as a large number of tubes are practicing, due to its high swiftness, especially behind than than sum also pusher puller technology.

MagWave – MagWave is unconventional technique based happening for electromagnetic technique, utterly same to eddy current. MagWave however, uses a saturating coil to magnetically saturate the material live thing inspected. This is useful for inspecting ferrous materials as ably as materials following skinny walls. MagWave works pleasurable upon materials such as Monel.
LFET – Low Frequency Electromagnetic Technique is another electromagnetic technique that is satisfying for tube inspection. LFET however is an outside technique, so is more useful for piping, boiler tubes, or tubes that have been removed from the condenser. LFET is immediate, and all-powerful for the unexpected inspection of tubes.
