Abstract
The invention discloses a heat preservation pipeline and relates to the technical field of petroleum pipelines. The heat preservation pipeline comprises an inner barrel (1), a heat preservation layer (3), an asphalt layer (4) and an outer barrel (5). Supporting columns are arranged between the heat preservation layer (3) and the inner barrel (1). The supporting structure of the heat preservation pipeline can play a supporting function, and clearances among the supporting columns can play a heat preservation and insulation effect to some extent.
Description
Technical field
The present invention relates to petroleum pipe line heating device technology area, it provides a kind of thermal insulatnig petroleum pipeline road.
Background technology
Oil is in oil recovery process, owing to oil is too high containing cured amount, carry oil concentration big, often cause oil pipeline oil transportation difficulty, especially in cold season, heating on petroleum pipe line is needed to solve the problem of oil transportation difficulty, existing electric heater for petroleum pipeline is generally be arranged on petroleum pipe line outer wall, and petroleum pipe line is in order to be incubated, often cylinder in the many employings of petroleum pipe line, thermal insulation layer and urceolus, although the setting of thermal insulation layer can reduce scattering and disappearing of the interior oil heat of pipe, but heat insulation effect is not good enough, and it is not corrosion-resistant, work-ing life is short, particularly general inside and outside two-tube between, namely also need to set up necessary safeguard structure between outer tube body internal surface and interior tube body outside surface, rectificate stability far away later.
Summary of the invention
In order to address the aforementioned drawbacks, it is an object of the invention to provide a kind of thermal insulatnig petroleum pipeline road.
In order to realize above-mentioned purpose the present invention by the following technical solutions:
A kind of thermal insulatnig petroleum pipeline road, it comprises interior cylinder (1), thermal insulation layer (3), brea bed (4), urceolus (5), is provided with and supports between thermal insulation layer (3) and interior cylinder (1).
In technique scheme, described interior cylinder (1) adopts aluminium.
In technique scheme, thermal insulation layer (3) adopts glass wool.
In sum, hinge structure of the present invention, has following useful effect:
Supporting structure of the present invention can be played a supporting role, and certain function of heat insulation can be played in the space between supporting.
Accompanying drawing explanation
Fig. 1 is for the invention is intended to;
Cylinder in 1-in figure, 2-support, 3-thermal insulation layer, 4-brea bed, 5-urceolus.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
A kind of thermal insulatnig petroleum pipeline road, it is characterised in that: comprise interior cylinder 1, thermal insulation layer 3, brea bed 4, urceolus 5, it is provided with between thermal insulation layer 2 and interior cylinder 1 and supports.
In technique scheme, described interior cylinder 1 adopts aluminium.
In technique scheme, thermal insulation layer 3 adopts glass wool.
Claims (3)
