Abstract
The invention discloses a petroleum heat insulation pipeline. The pipeline comprises an inner steel pipe, wherein an asphalt felt layer, a calcium silicate tile layer, an outer steel pipe and a polyethylene layer are sequentially arranged on the outer wall of the inner steel pipe from inside to outside. The pipeline is suitable for being laid underground, the space between the inner steel pipe and the outer steel pipe is filled with a heat insulation material, and the outer steel pipe is coated with the polyethylene layer to enhance corrosion resistance of the pipeline.
Description
Technical field
The present invention relates to petroleum pipeline technical field, especially a kind of heat-insulating oil pipeline.
Background technology
Oil is a kind of pitchy being made up of various hydro carbons or dirty-green viscous liquid state or semi-solid combustible, especially
It is when temperature is relatively low, and the stickiness of oil increases, and mobility weakens, and easily blocks in course of conveying.In order to keep away
Exempt to occur petroleum pipeline clogging in autumn and winter microthermal climate, particularly in pipeline buried-pipe laying it should carry out petroleum pipeline
Road is incubated.
Content of the invention
The invention aims to solving the above problems, there is provided a kind of heat-insulating oil pipeline.
The purpose of the present invention to implement by the following technical programs：
A kind of heat-insulating oil pipeline, including in steel pipe, described interior outer wall of steel pipe is followed successively by malthoid layer, calcium silicates tile from inside to outside
Layer, outer steel pipe and polyethylene layer.
Further, the thickness of described calcium silicates tile layer is 80-150mm, and the thickness of polyethylene layer is 1.5-3mm.
Beneficial effects of the present invention are：
The heat-insulating oil pipeline that the present invention provides, is suitable for buried-pipe laying, fills insulation material between interior steel pipe and outer steel pipe,
Layer of polyethylene is applied on outer steel pipe, strengthens the corrosion resistance of pipeline.
Brief description
Fig. 1 is the structure chart of heat-insulating oil pipeline of the present invention.
In figure：Steel pipe in 1-；2- malthoid layer；3- calcium silicates tile layer；The outer steel pipe of 4-；5- polyethylene layer.
Specific embodiment
As shown in figure 1, heat-insulating oil pipeline described in the embodiment of the present invention, including in steel pipe 1, interior steel pipe 1 outer wall wraps
Wrap up in malthoid layer 2, interior 1 set of outer steel pipe 4 of steel pipe, the thick calcium silicates watt of filling 80-150mm between interior steel pipe 1 and outer steel pipe 4
Lamella 3, outer steel pipe 4 applies outward the thick polyethylene layer of 1.5-3mm, strengthens the corrosion resistance of pipeline.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to aforementioned reality
Apply example the present invention has been described in detail, for a person skilled in the art, it still can be to aforementioned each enforcement
Technical scheme described in example is modified, or carries out equivalent to wherein some technical characteristics.All essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
Claims (2)
1. a kind of heat-insulating oil pipeline, including in steel pipe it is characterised in that described interior outer wall of steel pipe is followed successively by malthoid from inside to outside
