摘要： Methods and devices for inspecting waterwall tubes for the detection of fire side damage over a long length of the tube are described. The system of the invention uses a magnetostrictive strip and a flat coil-type plate magnetostrictive sensor (MsS) that are held in place on the waterwall using a specially designed frame and an electromagnetic circuit. The magnetostrictive strip and plate type MsS are positioned against a tube in the waterwall using an elastomeric pad or a fluid filled bladder to achieve close contact and good mechanical coupling between the magnetostrictive strip and the tube surface. When current activated, the electromagnet holds the entire assembly in place and provides a DC bias magnetic field required for plate magnetostrictive sensor probe operation. Long-range guided-waves are pulsed into the tube and reflected signals are detected within the same sensor structure. The received signal data representative of a long section of the tube under investigation is then analyzed for the presence of anomalies and defects. When data acquisition for a particular tube or tube section is completed the electromagnet is turned off and the entire device is moved to the next tube in the waterwall.

摘要： Sensor assemblies and methods are described that facilitate the use of a long-range torsional guided-wave inspection system for inspecting pipes, tubes, or other longitudinal cylindrical structures, with a partial excitation and detection around the pipe circumference. The sensor assemblies comprise a plate-type magnetostrictive sensor probe positioned beneath a compressible/expandable bladder and an inverted U-shaped frame that retain and position the sensor probe against the external wall of the pipe under inspection. Preferably, a magnetostrictive strip is positioned in direct contact with the pipe wall over which the plate magnetostrictive sensor probe is positioned. The probe is preferably curved to match the curvature of the external surface of the pipe. A pad may be positioned between the probe and the magnetostrictive strip to improve compliance with irregular pipe surfaces. The frame (and therefore the sensor assembly) is held in place by a belt that encircles the pipe and may be tensioned in order to pull the frame against the pipe, and through the compressive force associated with the bladder, direct the magnetostrictive sensor probe against the surface of the pipe or against the magnetostrictive strip positioned on the surface of the pipe. Methods are described for placement of the magnetostrictive strip and the positioning of the magnetostrictive sensor probe.

摘要： Provided are an ultrasonic testing probe and an ultrasonic testing apparatus capable of reducing the time required for flaw detection while maintaining the flaw-detection capability, irrespective of the shape of the inner surface of a tested object. A first probe (21) and a second probe (22) are provided, in each of which a plurality of oscillators that transmit ultrasonic waves to a tested object (T) and detect the ultrasonic waves reflected from the tested object (T) are arrayed. The first probe (21) is disposed closer to a flaw in the tested object (T) than the second probe (22) is. The first probe (21) generates longitudinal ultrasonic waves that propagate on an inner surface (T5) of the tested object (T) opposite to an outer surface (T2) thereof where the first probe (21) and the second probe (22) are disposed and transverse ultrasonic waves that propagate from the outer surface (T2) toward an inside of the tested object (T). The second probe (22) generates longitudinal ultrasonic waves that propagate on the outer surface (T2) and longitudinal ultrasonic waves that propagate from the outer surface (T2) toward the inside of the tested object (T).

摘要： An inspection device and an inspection method for boiler furnace water wall tubes. The inspection device includes a scanner including columns placed upright and fixed by magnets onto the surfaces of multiple water wall tubes extending in the up-down direction on the inner wall surfaces of the boiler furnace, a support frame fixed to the columns to support a displacement sensor producing laser light to be irradiated onto the surface of a water wall tube, and a moving mechanism for moving the displacement sensor in the axial direction of the water wall tube relative to the support frame. A signal processing unit calculates the amount of reduced wall thickness of the water wall tube from a difference between the cross-sectional surface shape of the water wall tube based on a signal from the displacement sensor and a reference shape without reduction in wall thickness.
