Tank Floor Scanner is widely used NDT technique for the inspection of tank walls. Magnetic flux leakage principle is applied here for the inspection of tank bottom plates. Unlike the basic conventional NDT- MPI, the tank floor equipment uses sensors to detect the leakage field due to corrosion, pitting, wall loss and will be recorded in the system connected to Sensors.
For in-service inspection of tank plates, pipeline corrosion monitoring MFL is widley used. It is faster than other corrosion mapping techniques and also give better results. Dimensions of the defects can be well determined with this technology as the system uses encoders, software’s to track and record data
