The Application of Ultrasonic Nondestructive Testing Technology in Refrigeration Pipeline

Abstract

The working principle of refrigeration equipment is that the refrigerant changes state in the pipeline under the action of the compressor, so as to achieve the effect of refrigeration and cooling, so there can be no defects in the internal metal pipeline. Ultrasonic nondestructive testing technology is an efficient, accurate and non-invasive evaluation method, with the advantages of non-destructiveness, high precision, high efficiency, flexibility and low cost. It will not cause any damage to the refrigeration pipeline, ensuring the safety of the detection process and the integrity of the pipeline. At the same time, modern ultrasonic testing equipment has high resolution and sensitivity, which can accurately detect tiny defects and improve the reliability and accuracy of detection. In addition, the technology is suitable for refrigeration pipelines of various materials and shapes, including metal, non-metal and complex geometric shapes, and has a wide range of applicability. This paper attempts to summarize and analyze the nondestructive testing technology of ultrasonic waves in metal pipelines, explain the principles and methods of ultrasonic testing, and has important significance for promoting the development of nondestructive testing technology.
