Abstract: The present invention discloses a pipe material including the pipe body. Spacers are set inside the pipe body. The outer wall of the spacer is in close fit with the inner wall of the pipe body. In the present invention, the spacer set inside the pipe material can well support the pipe wall and better enhance the mechanical strength and anti-bending performance of the pipe.

The interaction of multiple spacers ensures the local stability of the pipe body between spacers. The interaction between the spacer and the pipe wall ultimately improves various performances of the pipe, especially its anti-bending performance.
