Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic analysis of storage tank bodies, and in particular to an ultrasonic guided wave monitoring device for corrosion of storage tank bodies. Background Art

[0002] In many industries such as petroleum and chemical industry, storage tanks are widely used to store various liquid or gaseous media. However, the tank body is prone to corrosion damage due to long-term corrosion by internal media, erosion by the external environment, and stress. This may not only lead to medium leakage and safety accidents, but also cause huge economic losses. Therefore, it is extremely important to effectively monitor the corrosion condition of the tank body. As an emerging non-destructive testing technology, ultrasonic guided wave detection technology has shown unique advantages in the detection of long-distance pipelines and plate structures, and has gradually been applied to the detection field of storage tank bodies. Ultrasonic guided waves can propagate over long distances in the structure, and can achieve rapid scanning and detection of large areas, reducing detection time and cost.

The present invention reduces the sagging of the magnetic suspension on the inner wall of the tank body by a heating plate, ensures that the magnetic powder is relatively evenly distributed, and improves the device's ability to detect the corrosion resistance of the tank body.
