Description

Technical Field

[0002] Firefighting piping refers to the pipe materials used in firefighting to connect firefighting equipment and devices and transport firefighting water, gas, or other media. Because firefighting piping is often stationary, stringent requirements apply to it, requiring it to withstand pressure, corrosion, and high temperatures. Before installation and construction of firefighting piping, it is necessary to conduct quality inspections. The most common method for inspecting pipelines is non-destructive testing (NDT), a non-invasive testing technique that uses NDT equipment to assess the integrity and performance of pipelines without damaging the structure.

[0003] Existing nondestructive testing equipment typically requires a worker to hold a probe and then move it to locate and detect defects on the pipe surface. However, manual testing is not only cumbersome but also unstable. It is not convenient to fully inspect different locations on the pipe wall and is prone to missing some inspection areas, resulting in low inspection efficiency and affecting detection accuracy. To address this issue, we designed a pipeline inspection device for fire protection engineering. Summary of the Invention

When the penetrant enters the cracks and pores on the inner wall of the pipeline, the penetrant in that part will be reduced, so that the color developer will not be completely colored, resulting in a difference in color in that area, which is convenient for the staff to find and detect defects such as cracks, gaps and pores on the inner wall of the pipeline.
