Abstract
The present invention relates to a system for the nondestructive testing of the thickness of boiler tubes. The system comprises a probe assembly which includes a mounting unit for mounting the assembly in a mud or water drum of a boiler at the location of a boiler tube to be tested. The probe assembly is comprised of an ultrasonic transducer for transmitting and receiving ultrasonic signals. The probe assembly further includes a motor drive connected to the transducer. A control unit is provided which includes a motor control portion connected to the motor drive to selectively position the transducer at a plurality of locations in the boiler tube to be tested. The control unit also includes an ultrasonic drive for producing an ultrasonic pulse for driving said transducer means. A water control is connected to the control unit, a source of water supply, a drain, and the probe assembly. The water control selectively fills the boiler tube in a region of the boiler tube prior to testing and drains the boiler tube after testing. An electronic storage unit is provided, connected to the transducer, via the control unit for storing data relating to wall thicknesses at each of the plurality of locations. An output stage is provided which is connected to the storage unit via the control unit for outputting the data.
