[0002] HDPE winding reinforced pipe is a pipe product made mainly of high-density polyethylene (HDPE). It has excellent wear resistance, corrosion resistance and pressure resistance, and is suitable for various pipeline projects for transporting media, including water, sewage, chemicals, etc. HDPE winding reinforced pipes usually adopt special production processes, and the strength and pressure resistance of the pipes are improved by winding reinforcing materials (usually fiberglass or carbon fiber) outside the HDPE pipes. This design enables the pipes to withstand high pressures and temperatures and has a long service life. It is a pipe product with superior performance, reliability and durability.

[0003] However, due to the limitations of material properties, at present, both the outer wall and the inner wall of the wound corrugated pipe are made of PE materials, and the price of PE materials is relatively high. Although the wound corrugated pipe made entirely of PE materials can obtain good performance, the production cost is relatively high. Moreover, in some occasions that require high strength, the all-PE pipe cannot meet the high-strength requirements, is easily deformed by external forces, and even breaks, resulting in a shortened service life of the wound flat-wall pipe. Summary of the Utility Model

[0022] As shown in the attached Figure 1 to the attached Figure 4 figures, an embodiment of the present utility model provides a high-strength HDPE winding reinforced pipe, which includes a pipe body 1. Connecting pipe orifices 2 are fixedly connected to both ends of the pipe body 1. A reinforcing rib 3 is fixedly sleeved on the outer surface of the pipe body 1. The pipe body 1 includes an inner pipe 12. A wear-resistant layer 13 is bonded inside the inner pipe 12. A plurality of fixing rings 11 are evenly distributed on the outer surface of the inner pipe 12. An outer pipe 14 is bonded to the outer surface of the fixing ring 11. A protective layer is provided on the outer surface of the outer pipe 14.

[0023] As shown in the attached Figure 5 figures, the number of the fixing rings 11 is multiple. A steel wire mesh 15 is fixedly connected between the multiple fixing rings 11. A plurality of elastic ribs 16 are fixedly connected to the outer surface of the steel wire mesh 15. The plurality of elastic ribs 16 are evenly distributed on the outer surface of the steel wire mesh 15. By using the provided elastic ribs 16, the supporting force between the multiple fixing rings 11 is increased. While improving the bearing capacity of the steel wire mesh 15, the radial supporting capacity of the HDPE winding reinforced pipe is increased.

[0024] As shown in the attached Figure 4 figures, the fixing ring 11 includes an inner ring 111 and an outer ring 112. A plurality of reinforcing strips 113 are fixedly connected between the inner ring 111 and the outer ring 112. An intersecting V-shaped structure is formed between the plurality of reinforcing strips 113. By using the structure between the reinforcing strips 113, the supporting force of the fixing ring 11 is improved, thereby increasing the radial supporting capacity of the HDPE winding reinforced pipe and improving the firmness strength of the fixing ring 11.

[0025] Among them, the inner ring 111 is fixedly installed on the outer surface of the inner pipe 12. The outer surface of the outer ring 112 and the steel wire mesh 15 is fixedly connected to the inner wall of the outer pipe 14.

[0026] By providing the fixing ring 11 and the steel wire mesh 15, when the surface of the HDPE winding reinforced pipe is subjected to pressure, the inner surface of the outer pipe 14 is supported by the elastic ribs 16 and the steel wire mesh 15, the pressure borne is absorbed, and in cooperation with the setting of the steel wire mesh 15, the generated pressure is buffered, so that the HDPE winding reinforced pipe has better compressive capacity and effectively avoids the inner pipe 12 from being broken due to force.

[0027] Among them, the reinforcing rib 3 includes an HDPE outer sleeve 31, the HDPE outer sleeve 31 is spirally and fixedly connected to the outer surface of the outer pipe 14, a sleeve hole 32 is formed inside the HDPE outer sleeve 31, and a reinforcing iron wire 33 is fixedly sleeved inside the sleeve hole 32.

[0028] Among them, the protective layer is a UPVC layer.

[0029] Among them, the wear-resistant layer 13 is made of carbon fiber material. By using the wear-resistant layer 13, the inner wall of the wear-resistant layer 13 itself also has good wear resistance, avoiding the wear of impurities contained in the conveying medium on the inner wall of the wear-resistant layer 13, thereby affecting the service life of the wear-resistant layer 13.

While improving the bearing capacity of the wire mesh 15, when the surface of the HDPE wound reinforced pipe is subjected to pressure, the inner surface of the outer pipe 14 is supported through the elastic ribs 16 and the wire mesh 15, the applied pressure is absorbed, and in cooperation with the arrangement of the wire mesh 15, the generated pressure is buffered, so that the HDPE wound reinforced pipe has better compressive capacity and effectively avoids the inner pipe 12 from being damaged due to force;

[0032] By using the HDPE outer sleeve 31 and the reinforcing iron wire 33, the axial direction of the HDPE wound reinforced pipe is supported. At the same time, by using the reaction force of the reinforcing iron wire 33 itself, the axial force of the HDPE wound reinforced pipe is buffered and supported, and in cooperation with the wire mesh 15 and the elastic ribs 16, thereby improving the axial support force of the HDPE wound reinforced pipe.
