Abstract

The utility model pertains to the transmission pipeline technology field and in particular discloses a steel composite pipe for mines and oilfields. The main technology is characterized in that: the utility model contains an inner pipe body; an inner wire line layer and an outer wire line layer that spirally wind along different direction are positioned outside the inner pipe body in turn; the outer wall of the outer wire line layer is covered by an outer pipe body. As a further improvement of the utility model, the helix angle of the inner wire line layer 2 and the outer wire line layer 3 is 30-60 degrees, thereby resolving the problem that the transmission pipeline made of the current plastic material has poor pressure resistance and the metal pipeline has poor corrosion resistance, friction resistance and anti fouling performance. The utility model is widely applied to the field such as mines and oilfields.

Description

Steel is compiled composite pipe
Technical field
The utility model belongs to the pipe technology field, relates in particular to the conveyance conduit of a kind of mine, oil field use.
Background technique
At present, the conveyance conduit of liquid such as conveying crude oil and tailings is made by materials such as polyvinyl plasticss mostly on oil field and mine.That this conveyance conduit has is corrosion-resistant, rub resistance, good antiscale property performance, than metallic conduit long service life, and has reduced cost.But this conveyance conduit compressive strength is low, uses plastic pipe in the occasion that pressure is big slightly, causes danger easily.Therefore, can only adopt metallic conduit in this kind occasion, because corrosion-resistant, the rub resistance of metallic conduit, good antiscale property poor performance, working life is short, the cost of production height.
The model utility content
Problem to be solved in the utility model just provides the steel of a kind of corrosion-resistant, rub resistance, good antiscale property, good pressure-resistant performance, long service life and compiles composite pipe.
For addressing the above problem, the technical solution adopted in the utility model is: comprise interior tube body, outside described interior tube body, be enclosed with successively the interior tinsel layer that twines along the different direction spiral and outside the tinsel layer, and the coated outside of tinsel layer has outer tube body outside.
Its additional technical feature is: the helix angle of tinsel layer and outer tinsel layer is 30 degree-60 degree in described; The helix angle of tinsel layer and outer tinsel layer is 45 degree in described.
Steel provided by the utility model is compiled composite pipe compared with prior art, have the following advantages: one, since outside interior tube body, be enclosed with successively the interior tinsel layer that twines along the different direction spiral and outside the tinsel layer, and the coated outside of tinsel layer has outer tube body outside, has improved the compressive strength of conveyance conduit greatly; Its two because the tinsel layer is surrounded by interior tube body and outer tube body, improved corrosion-resistant intensity; Its three spend because the helix angle of interior tinsel layer and outer tinsel layer is 30 degree-60, make the intensity of conveyance conduit further increase.
Description of drawings
Accompanying drawing is compiled the structural representation of composite pipe for the utility model steel.
Embodiment
Concrete structure and the use principle of the utility model steel being compiled composite pipe below in conjunction with accompanying drawing are described in further details.
As shown in drawings, the utility model steel is compiled composite pipe and is comprised the interior tube body of being made by polyethylene or other corrosion-resistant materials 1, the outer wall of interior tube body 1 be enclosed with successively the interior tinsel layer 2 that twines along the different direction spiral and outside tinsel layer 3, tinsel layer 3 coated outside have outer tube body 4 outside.
In order to improve the compressive strength of conveyance conduit, the helix angle of interior tinsel layer 2 and outer tinsel layer 3 is set to 30 degree-60 degree.Certainly, be preferably 45 degree.

Claims (3)

1, steel is compiled composite pipe, comprises interior tube body, it is characterized in that: outside described interior tube body, be enclosed with successively the interior tinsel layer that twines along the different direction spiral and outside the tinsel layer, and the coated outside of tinsel layer has outer tube body outside.
2, steel according to claim 1 is compiled composite pipe, it is characterized in that: the helix angle of tinsel layer and outer tinsel layer is 30 degree-60 degree in described.
3, steel according to claim 2 is compiled composite pipe, it is characterized in that: the helix angle of tinsel layer and outer tinsel layer is 45 degree in described.
