Pipe wall thinning in the secondary piping system of a nuclear power plant is currently a major problem that typically affects the safety and reliability of the nuclear power citroen c4 grand picasso boot liner plant directly.Regular in-service inspections are carried out to manage the piping system only during the overhaul.Online thickness monitoring is necessary to avoid abrupt breakage due to wall thinning.To this end, a transducer that can withstand a high-temperature environment and should be installed under the insulation layer.We propose a thin plate type of embedded ultrasonic transducer based on magnetostriction.

The transducer was designed and fabricated to measure the thickness of a pipe under k24a4 block a high-temperature condition.A number of experimental results confirmed the validity of the present transducer.
