Abstract

The utility model relates to a composite tube which comprises an inner layer, a metal composite layer and an outer layer. The metal composite layer is positioned between the inner layer and the outerlayer. The composite tube is characterized in that the metal composite layer adopts a metal wire helically enwound on the inner layer; and the metal wire is tightly arranged between the inner layer and the outer layer in a helical manner. Glue binding layers are arranged among the metal composite layer, the inner layer and the outer layer. The metal wire adopts a steel wire. The utility model hasthe advantages of high strength, simple structure, static elimination and convenient manufacture.

Description

A kind of composite pipe

Technical field

The utility model relates to a kind of building pipe, particularly a kind of composite pipe.

Background technique

Along with wideling popularize of national environmental protection policy, polypropylene tube has comprehensive advantage because of it at aspects such as health, heatproof, withstand voltage, toughness, so polypropylene tube has obtained using widely in China's every field.In use there are shortcomings such as tension, compressive strength are not enough, frangible, electrostatic precipitation in existing polypropylene tube, causes pipe shaft to break, hold the Electrostatic Absorption dirt easily, causes that pipe shaft pollutes.For solve existing polypropylene tube tension, compressive strength is low, problems such as easy electrostatic precipitation, the PPR composite pipe of metal composite layer has appearred increasing in polypropylene tube at present, but the metal composite layer in this PPR composite pipe is the wire of braiding structure, this PPR composite pipe manufacturing process complexity, often occur the uneven situation of braiding in the braiding process, the easy like this metal composite layer density unevenness that causes is even, influences tension, the compressive strength of PPR composite pipe.

Summary of the invention

The technical problems to be solved in the utility model is, provide a kind of intensity height, simple in structure, can eliminate static, and the convenient composite pipe of making.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of composite pipe, comprise internal layer, metal composite layer and skin, metal composite layer is characterized in that between internal layer and skin: metal composite layer is the wire that is spirally wound on the internal layer.

Described wire shape in the shape of a spiral closely is arranged between internal layer and the skin.

Be equipped with the glue adhesive layer between described metal composite layer and internal layer and the skin.

Described wire is a steel wire.Described wire also can adopt copper wire or Al-alloy metal silk.

The utility model adopts wire to be wrapped in inner layer outer wall as metal composite layer, wire shape in the shape of a spiral closely is arranged between internal layer and the skin, and be equipped with the glue adhesive layer between wire and internal layer and the skin, wire can combine densely with internal layer and skin like this, make the composite pipe bulk strength become big, and can eliminate the static that produces in the composite pipe using process.The utility model simply twines by wire, just can form metal composite layer uniformly densely between composite pipe internal layer and skin, and is not only simple in structure, and convenient the manufacturing.

In sum, the utlity model has the intensity height, simple in structure, can eliminate static, and the convenient beneficial effect of making.

Embodiment

As Fig. 1, Fig. 2, shown in Figure 3, a kind of composite pipe comprises internal layer 1, metal composite layer 2 and skin 4, and metal composite layer 2 is between internal layer 1 and outer 3, and metal composite layer 2 is for being spirally wound on the wire on the internal layer 1.Wire shape in the shape of a spiral closely is arranged between internal layer 1 and outer 3.Be equipped with glue adhesive layer 4 between metal composite layer 2 and the internal layer 1 and outer 3, glue adhesive layer 4 makes the more firm of metal composite layer 2 and internal layer 1 and outer 3 bondings.The internal layer 1 of composite pipe and outer 3 all adopts the atactic copolymerized polypropene material, i.e. the PPR material.Wire adopts steel wire.
