Technical Field

[0001] This utility model relates to the field of composite pipe technology, specifically to a spiral steel cord reinforced polyethylene wear-resistant composite pipe. Background Technology

[0002] Currently, wear-resistant composite pipes are industrial pipelines manufactured using multi-layer material composite technology. Their core feature is the use of the synergistic effect of different materials to improve wear resistance, and they are mainly used to transport liquid materials.

[0003] Currently, the flow within composite pipes is mainly controlled by conveying equipment, and the flow within the pipe is uniform, making it impossible to extend the flow within the pipe. When conveying hot liquids, heat dissipation treatment is required for the hot liquids, but the fixed pipes result in reduced heat dissipation efficiency. Utility Model Content

[0004] This utility model provides a spiral steel cord reinforced polyethylene wear-resistant composite pipe. Through the composite inner pipe, spiral steel strip and spiral cross divider, the flow velocity of the liquid in the pipe can be extended by using spiral cross dividers with different spirals, thereby increasing the heat dissipation efficiency of the liquid in the pipe and making the liquid flow in spiral rotation, making the flow more stable.

[0011] This utility model provides a spiral steel cord reinforced polyethylene wear-resistant composite pipe. It has the following beneficial effects:

[0012] This spiral steel cord reinforced polyethylene wear-resistant composite pipe, through its composite inner tube, spiral steel strips, and spiral cross dividers, can utilize different spiral cross dividers to extend the flow velocity of the liquid inside the pipe, thereby increasing the heat dissipation efficiency of the liquid inside the pipe and making the liquid flow in a spiral rotation, resulting in a smoother flow.

Three spiral steel strips 4 are fixedly embedded at equal intervals along the circumferential surface between the composite outer tube 1 and the filling layer 2. A threaded cross divider 5 is fixedly embedded in the inner wall of the composite inner tube 3. An anti-wear layer 6 is fixedly sleeved on the outer wall of the composite outer tube 1.

[0020] In this implementation scheme: a composite pipe is formed by a composite outer pipe 1, a filling layer 2, and a composite inner pipe 3. At the same time, three spiral steel bars 4 are embedded to increase the strength of the pipe. The threaded cross divider 5 can make the liquid flow in the pipe spiral and divide the flowing liquid into multiple streams. By using different thread degrees, the speed of liquid flow can be changed, increasing the time that the liquid flows in the pipe, thereby improving the heat dissipation of the pipe. The wear-resistant layer 6 increases the wear resistance of the outer wall of the pipe.

[0021] Specifically, both the outer composite tube 1 and the inner composite tube 3 are made of polyethylene material.

By using different thread degrees, the speed of liquid flow can be changed, increasing the time that the liquid flows in the pipe. Multiple flow holes are used to allow flow between the streams.

[0027] Specifically, the wear-resistant layer 6 is made of carbon fiber.

[0028] In this embodiment, the wear-resistant layer 6 is made of carbon fiber to increase the wear resistance of the outer wall of the pipe.
