Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated pipes, and particularly relates to a P0E polymer compression-resistant composite double-wall corrugated pipe. Background Art

[0002] As an important fluid transportation device, corrugated pipes are widely used in industries such as petroleum, chemical industry, electric power, and water conservancy.

[0003] The traditional corrugated pipe has weak compression resistance. During the transportation and construction of the pipe, due to external forces such as bumps and squeezes, the corrugated structure on the outer wall of the pipe is concavely deformed, resulting in the overall flattening or cracking of the pipe. At the same time, the long-term buried extrusion of the corrugated pipe easily causes the pipe body to be damaged, which is not convenient for use. Therefore, a P0E polymer compression-resistant composite double-wall corrugated pipe with good compression performance is proposed. Summary of the Invention

The corrugated outer wall layer uses POE elastic composite material, which provides good elasticity and durability. The corrugated design increases the strength and flexibility of the pipeline, enabling it to resist external pressure. The reinforcing rib plate improves the connection stability and enhances the overall strength of the pipeline. The compression layer adopts a wire cross-net structure, which enhances the compression resistance of the pipeline, can withstand greater external pressure, has high strength, high durability and good compression performance, and is suitable for pipeline applications in various harsh environments.

The reinforcing rib plates for improving the connection stability are installed on the corrugated outer wall layer at equal intervals. The sealing layer is installed between the smooth inner wall layer and the corrugated outer wall layer to connect the smooth inner wall layer and the corrugated outer wall layer. A cavity sandwich is formed between the smooth inner wall layer and the corrugated outer wall layer. The compression layer is installed inside the cavity sandwich, and the compression layer is set as a wire cross-net structure. From the inside to the outside, there are sequentially arranged a smooth inner wall layer, a compression layer, and a corrugated outer wall layer.

[0016] The utility model discloses a P0E polymer compression-resistant composite double-wall corrugated pipe. The P0E polymer compression-resistant composite double-wall corrugated pipe mainly comprises a smooth inner wall layer 1, a corrugated outer wall layer 2, a sealing layer 3, reinforcing rib plates 4, and a compression-resistant layer 5. The corrugated outer wall layer 2 is installed outside the smooth inner wall layer 1. The smooth inner wall layer 1 is made of high-density polyethylene material, and the corrugated outer wall layer 2 is made of POE elastic composite material. The reinforcing rib plates 4 for improving the connection stability are installed on the corrugated outer wall layer 2 at equal intervals. The sealing layer 3 is installed between the smooth inner wall layer 1 and the corrugated outer wall layer 2 to connect the smooth inner wall layer 1 and the corrugated outer wall layer 2. A cavity sandwich layer is formed between the smooth inner wall layer 1 and the corrugated outer wall layer 2. The compression-resistant layer 5 is installed inside the cavity sandwich layer. The compression-resistant layer 5 is arranged in a wire cross-net structure. From the inside to the outside, there are arranged the smooth inner wall layer 1, the compression-resistant layer 5, and the corrugated outer wall layer 2 in sequence.

[0017] Fluids enter the pipeline through the smooth inner wall layer 1. Due to the smooth inner wall of the high-density polyethylene material, the fluid flow resistance is small, and the fluid transportation efficiency is high. The corrugated outer wall layer 2 and the reinforcing rib plates 4 provide good elasticity and durability, can resist external pressure, and ensure the structural stability of the pipeline. The compression-resistant layer 5 adopts a wire cross-net structure, enhancing the compression resistance of the pipeline and being able to withstand greater external pressure. The anti-corrosion treatment and the pressure-reducing filler 6 further improve the corrosion resistance and compression resistance of the pipeline and extend the service life.
