Abstract

The invention discloses a heating heat-preserving petroleum transportation pipeline, which comprises a petroleum pipeline (1), and is characterized in that: a heating layer (2) is arranged on the outer wall of the petroleum pipeline (1), and a heat-preserving layer (3) is wrapped outside the heating layer (2); and the length range of the heating layer (2) is 0.5m to 1m. The heating heat-preserving petroleum transportation pipeline has a simple structure, ingenious design and high heat conversion rate, and is convenient to install and maintain.

Description

Heating and heat-insulating type oil delivering pipe

Technical field

The present invention relates to a kind of oil delivering pipe, especially a kind of can be to heating in the pipeline, and have the heating and heat-insulating type oil delivering pipe of heat insulation function.

Background technique

At present, can realize that the structure of petroleum pipeline heating generally has two kinds, a kind of is the hot water pipe box of socket heat supply water flows outside petroleum pipeline; Utilize the hot water in it to come petroleum pipeline is heated; But this structure is not only bulky, and cost is expensive, and if the situation that boiler stops to heat; The easy bursting by freezing of (like winter) water pipe under comparatively cold environment causes the accident.Another kind of heating arrangement then adopts the mode of electric heating wire; Electric heating wire is wrapped on the outer wall of petroleum pipeline, though this structure advantages of small volume, because the area of contact between electric heating wire and the petroleum pipeline is less; The thermal efficiency is lower; It is higher to consume energy, in case and the electric heating wire problem that occurs opening circuit, the maintenance trouble very of getting up.Therefore need a kind of nonpetroleum pipeline heating arrangement that can address the above problem now.

Summary of the invention

The present invention is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, designs ingeniously, and heat conversion is high, installs, heating and heat-insulating type oil delivering pipe easy to maintenance.

Technical solution of the present invention is: a kind of heating and heat-insulating type oil delivering pipe, comprise petroleum pipeline 1, and it is characterized in that: the outer wall of described petroleum pipeline 1 is provided with zone of heating 2, and outside zone of heating 2, also is coated with thermal insulation layer 3.

The length range of described zone of heating 2 is a 0.5-1 rice.

The present invention compares with existing technology, has following advantage:

The oil delivering pipe of this kind of structural type, it is simple in structure, designs ingenious; Its special construction can be realized higher heat conversion, has improved the efficiency of heating surface, cuts operating costs; Its creationary modularization zone of heating design simultaneously makes it in installation, more convenient and flexible when using; If the breakage of zone of heating only need be changed damaged zone of heating and get final product, the cost and the work of inspection and maintenance have greatly been reduced.Therefore we can say that this heating and heat-insulating type oil delivering pipe has possessed multiple advantage, be particularly suitable in the oil carrier, applying that its market prospects are comparatively wide.

Description of drawings

Fig. 1 is the structural representation of the embodiment of the invention.

Fig. 2 is that the A-A of Fig. 1 is to sectional view.

Embodiment

Below with accompanying drawings embodiment of the present invention.Like Fig. 1, shown in Figure 2: a kind of heating and heat-insulating type oil delivering pipe, comprise petroleum pipeline 1, the outer wall of petroleum pipeline 1 is provided with zone of heating 2, and the length span of zone of heating 2 is: 0.5-1 rice, optimum value are 0.8 meter; Outside zone of heating 2, also be coated with thermal insulation layer 3, can slow down the heat that zone of heating 2 produced and distribute to the external world.

In the winter of cold; The oil delivering pipe of the embodiment of the invention is when work, and zone of heating 2 is worked, and the heat of generation is sent in the petroleum pipeline 1; Simultaneously because the existence of thermal insulation layer 3; Zone of heating 2 does not directly contact with ambient air, so this part heat again can be very not fast is dispersed into the external world, has improved the thermal efficiency.

And the zone of heating in the present embodiment 2 is a modular type; Promptly adjacent on the length direction of petroleum pipeline 1 a plurality of zones of heating 2 are set; Form total zone of heating, the benefit of this mode of structure is: be convenient to the maintenance man and find the concrete zone of heating 2 go wrong, and only need change problem, idle zone of heating 2 gets final product; Can reduce maintenance cost on the one hand, can also increase work efficiency on the other hand.

Claims

1. a heating and heat-insulating type oil delivering pipe comprises petroleum pipeline (1), it is characterized in that: the outer wall of described petroleum pipeline (1) is provided with zone of heating (2), and outside zone of heating (2), also is coated with thermal insulation layer (3).

2. heating and heat-insulating type oil delivering pipe according to claim 1 is characterized in that: the length range of described zone of heating (2) is a 0.5-1 rice.
