[0001] The utility model belongs to the technical field of pipeline marking, and relates to a pipeline rolling marking device, in particular to a small-diameter pipeline rolling marking device. Background Art

[0002] Due to the limitation of the construction site, small-diameter pipes are usually mixed together after arrival, and the pipeline construction site requires a variety of pipes with different diameters, different wall thicknesses or different materials, which need to be identified by construction workers before use. In the prior art, after the pipelines pass the inspection upon arrival, identification plates indicating the pipe diameter, wall thickness and material are inserted into the pipe ports to distinguish them. However, due to the complex and harsh environment of the construction site, the identification plates are easily lost or corroded by the external environment, resulting in unclear information. Moreover, after the pipes are cut into multiple sections, the cut parts cannot be marked. The diameter, wall thickness and material of each small-diameter pipe cannot be accurately distinguished from the appearance alone, and low-diameter pipes are often used instead of high-diameter pipes or misused, which poses a great hidden danger to the safe operation of the pipeline system.
