Pipeline anti-crawling part

The utility model discloses a pipeline anti-crawling part. The anti-crawling part is a metal plate, wherein triangular holes and triangular thorns overturned towards one face outside the edge of the triangular holes are densely distributed on the metal plate; the holes and the thorns are formed by punching the metal plate with a triangular punching part. Furthermore, the metal plate is circular-arc-shaped, and the triangular thorns are overturned towards the outside of the circular arc. The anti-crawling part is formed by punching on the metal plate, is easy to machine, and is low in production cost; the triangular thorns are densely distributed on the metal plate, so that a climber can be prevented from climbing from a pipeline when the metal plate is arranged on the outer surface of the pipeline, and the potential safety hazard of buildings is eliminated greatly; the surface of the metal plate is coated with paint which plays a role in resisting rust, decorating and warning.
