High Speed Eddy Current Inspection of Non-Ferrous Tubes
The problem
Over the period of their life, a proportion of Tubes will suffer from erosion/corrosion, flaws in the material, as the tube wall thins or dependent on the type of cooling water and chemistry.
The Solution
TIPO HEAT EXCHANGERS High speed eddy current system can detect even the smallest of defects at an average rate of up to 5 tubes per minute for a 10 metre condenser.
Our system uses compressed air to propel the eddy current probe through the tube at a rate of up to 6 meters per second. The computerized control system detects the end of the tube and automatically stops and reverses, being pulled back through the tube at a speed of up to 3 meters per second, whilst surveying the tube wall for defects and metal loss. The results are recorded using special software and are analyzed by our PCN Level 2 inspector in real time.
