technical field

The invention relates to the field of pipeline detection, in particular to a pipeline flaw detection device.

Background technique

A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. In the prior art, engineers and technicians usually use pipeline detection equipment to check the leakage point of the pipeline, so that only the pipeline that has leaked can be detected, and the pipeline cannot be preventively detected, so it is difficult to effectively monitor the real-time status of the pipeline. Effectively avoid the possibility of pipeline leakage.
