Embodiment Construction

[0033] The following is attached Figure 1-8 The application is described in further detail.

[0034] The embodiment of the present application discloses a PE spiral pipe.

[0035] refer to figure 1 A PE spiral pipe includes an inner pipe 1 , an insulation layer 2 and an outer pipe 3 . The inner pipe 1 is arranged on the innermost side, and the insulation layer 2 is arranged between the inner pipe 1 and the outer pipe 3. The inner pipe 1, the insulation layer 2 and the outer pipe 3 cooperate with each other to make the water pipe have higher strength and toughness. When the water pipe is impacted by an external force, it is not easily deformed, thereby prolonging the service life of the water pipe.

[0036] refer to figure 1 and figure 2 A helical cavity 11 is opened inside the inner tube 1, and the inner tube 1 is provided with a reinforcing crystal bar 12 in the helical cavity 11, and the reinforcing crystal bar 12 is arranged inside the inner tube 1 to further improve...

Abstract

The invention relates to a PE spiral pipe and a machining device thereof, and belongs to the technical field of PE pipes. The PE spiral pipe comprises an inner pipe, a heat preservation layer and an outer pipe, the outer side of the inner pipe is arranged in a spiral shape, a spiral groove is arranged in the outer side of the inner pipe in a reserved mode, the heat preservation layer is provided with a protrusion matched with the groove, a spiral cavity is formed in the interior of the inner pipe, reinforcing crystal strips are arranged in the spiral cavity of the inner pipe, the outer pipe is arranged on the outer side of the heat preservation pipe, and spiral protruding strips are arranged at one end, away from the heat preservation pipe, of the outer pipe. The PE spiral pipe has the effect of being long in service life.

Description

technical field [0001] The present application relates to the technical field of PE pipes, in particular to a PE spiral pipe and a processing device thereof. Background technique [0002] PE is the English abbreviation of polyethylene. PE has excellent resistance to most domestic and industrial chemicals. At present, PE pipes made of PE materials are a kind of pipes with a wide range of applications. When processing PE pipes, PE pipes are usually manufactured using processing devices. [0003] Usually, the PE material is melted first, and then the melted PE material is stretched and molded. After the melted PE material is processed into a single-layer pipe, the single-layer pipe can be used as a drainage pipe. [0004] In view of the above-mentioned related technologies, the inventor believes that when the above-mentioned PE pipe is used as a drain pipe, when the drain pipe is bent by an external force, it is easy to cause damage to the structure of the drain pipe, thereby ...
