Abstract

The utility model discloses a kind of petroleum pipeline, be made up of, wherein on the outer wall of internal layer, be stained with heating wire four layers of being followed successively by skin, reinforced layer, thermal insulation layer and internal layer from outside to inside, this heating wire insulation layer institute is coated.The utility model adopts lamination layer structure, and buries heating wire underground wherein, realizes heating the oil in pipeline, reduces its viscosity; And thermal insulation property is strong, transfer oil is convenient; Resistance to pressure is good, not easily breakage occurs, and improves Security.

Description

Petroleum pipeline

Technical field

The utility model relates to oil transportation device technical field, especially a kind of petroleum pipeline for oil transportation.

Background technique

Must be transported to corresponding machining sector after petroleum production, just can more preferably be utilized, wherein the petroleum pipeline of transfer oil is then absolutely necessary equipment.Existing petroleum pipeline is straight tube structure, due to the viscosity of oil own, is easy to stick on tube wall, results in blockage, make troubles to transfer oil.

Summary of the invention

The utility model, for the deficiencies in the prior art, proposes a kind of petroleum pipeline, and transfer oil is convenient, not easily blocks.

In order to realize above-mentioned model utility object, the utility model provides following technological scheme: a kind of petroleum pipeline, form by four layers that are followed successively by skin, reinforced layer, thermal insulation layer and internal layer from outside to inside, wherein on the outer wall of internal layer, be stained with heating wire, this heating wire insulation layer institute is coated.

Further, this heating wire is for being spirally wound on inner layer outer wall.

Further, this reinforced layer is metal net layer.

Compared with prior art, the utility model has the following advantages: adopt lamination layer structure, and bury heating wire underground wherein, realize heating the oil in pipeline, reduce its viscosity; And thermal insulation property is strong, transfer oil is convenient; Resistance to pressure is good, not easily breakage occurs, and improves Security.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model petroleum pipeline.

Embodiment

Be described in detail the utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.

A kind of petroleum pipeline as shown in Figure 1, four layers of, reinforced layer 2, thermal insulation layer 3 and internal layer 5 outer 1 by being followed successively by from outside to inside are formed, the outer wall of internal layer 5 is stained with heating wire 4, this heating wire 4 insulation layer 3 institute is coated, the heat that such heating wire 4 produces all realizes the heating to internal layer 5, thus significantly reduce the viscosity of oil in pipeline, improve oil flow, decrease blocking.

Adopt in the periphery of internal layer 5 coated thermal insulation layer 3, make hot oil oil viscosity in internal layer 5 low, good fluidity; Again at thermal insulation layer 3 outer cladding reinforced layer 2, as metal net layer, improve the crushing resistance of integrated piping, not easily fracture phenomena occurs; Outermost surface more coated common plastics as outer 1.

Heating wire 4 be spiral wrap on the outer wall of internal layer 5, can magnetic field heating oil, the heating of pipeline PetroChina Company Limited. can be passed to through heat transfer again, make heating effect best, reduce and occur adhesion phenomenon at tube wall, thus avoid occurring blocking, be applicable to various oil transportation.

The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.

Claims

1. a petroleum pipeline, is characterized in that: form by four layers that are followed successively by skin, reinforced layer, thermal insulation layer and internal layer from outside to inside, wherein on the outer wall of internal layer, be stained with heating wire, and this heating wire insulation layer institute is coated.

2. petroleum pipeline as claimed in claim 1, is characterized in that: this heating wire is for being spirally wound on inner layer outer wall.
