Description

Technical Field

[0001] This utility model relates to the field of ultrasonic testing technology for stainless steel oil pipe welds, specifically to an ultrasonic testing device for stainless steel oil pipe welds. Background Technology

[0002] Ultrasonic testing of stainless steel oil pipe welds utilizes the physical properties of ultrasound waves, which reflect and refract at interfaces between different media, to perform non-destructive testing on internal and surface defects in stainless steel oil pipe weld joints. It is widely used in the quality control of high-pressure stainless steel oil pipes in the petroleum, chemical, and automotive industries. During testing, the ultrasonic probe emits high-frequency sound waves (typically 2-5MHz) towards the weld area. After penetrating the weld, if the sound waves encounter internal cracks, porosity, incomplete penetration, slag inclusions, or other defects, they will generate reflected waves. The testing instrument receives the reflected signals and converts them into electrical signals. By analyzing the waveform images, the location, size, and shape of the defects are determined, and whether the weld meets quality standards. The testing process does not damage the oil pipe itself, enabling precise inspection of the entire weld cross-section and avoiding risks such as pressure failure and media leakage due to weld defects.

[0003] For example, CN202122154834.6 discloses an ultrasonic testing device for weld inspection, which relates to the technical field of weld inspection. It addresses the problem that the flaw detector head of a flaw detector has a certain angle, making it difficult to clean impurities inside, leading to errors in the emission and reception of ultrasonic waves at the weld. The device includes a detection component and a cleaning component, with the cleaning component mounted on the detection component. The detection component includes an ultrasonic flaw detector body, a data cable, and a flaw detector head, which is electrically connected to the ultrasonic flaw detector body via the data cable. This application integrates a cleaning component into the ultrasonic flaw detector body. A motor drives a cylindrical cleaning cylinder to rotate, allowing for rapid and thorough cleaning of the flaw detector head. This effectively removes dirt from the angle of the flaw detector head, preventing impurities from affecting the generation and reception of ultrasonic waves, thus making the detection data more accurate. However, this ultrasonic testing device suffers from drawbacks such as easy displacement during testing leading to data deviation, disorganized storage causing easy loss of accessories, poor operational adaptability resulting in easy damage to core components, unsafe use, and susceptibility to moisture and oil contamination.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed an ultrasonic testing device for stainless steel oil pipe welds. Utility Model Content
