Description

Technical Field

[0001] The present invention relates to the technical field of pipeline detection, and in particular to pipeline detection equipment. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors, and valves for transporting gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, then flow from high-pressure areas to low-pressure areas in the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of uses, primarily in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations. In some cases, some stainless steel pipelines require welding, and the welds at these locations are typically inspected by staff to determine if they are acceptable. Currently, this is typically done using handheld ultrasonic detectors to inspect the welds around the surface of the pipeline, which is cumbersome to operate and has low inspection efficiency. Therefore, we have proposed a pipeline inspection device to address this issue. Summary of the Invention
