times that of ordinary plastic pipes. The hollow structure is lined with a high-strength steel skeleton, which effectively reduces the weight of the pipe itself, greatly Improve the stiffness of the pipe ring. ><:><:>
< r : rbrrMicrosoft Yahei,: : >: >The utility model relates to the technical field of pipes, and discloses a hollow wall plastic steel winding pipe, which includes steel The pipe wall has a first ring hole, the steel frame is placed in the first ring hole and abuts against the upper part of the first ring hole, and the pipe wall corresponds to the The outer surface at the first ring hole is in the shape of a convex arc. The outer surface of the pipe wall in the utility model is in the shape of a convex arc corresponding to the first ring hole in the pipe wall. In this way, the outer surface of the entire pipe is in the shape of a convex arc. It is uneven, that is, the outer surface of the place where the steel frame is placed in the pipe wall is convex, and the upper part of the steel frame placed in the first pipe wall abuts the upper part of the first ring hole. In this way, the external pressure is on Most of the pressure on the pipe wall of the pipe is borne by the steel frame in the pipe wall, while the pressure on the pipe wall without the steel frame is very small, which can greatly improve the ring stiffness of the pipe.
