Abstract
The invention discloses an anti-corrosion petroleum pipeline. The anti-corrosion petroleum pipeline comprises a steel pipe for conveying petroleum. An epoxy coal pitch resin layer, a dicyclopentadiene resin layer and a polyethylene layer are sequentially arranged on the outer wall of the steel pipe from inside to outside. The pipeline is high in alkali tolerance and suitable for being laid underground in alkaline land, and the service life of the pipeline reaches 50 years or longer.
Description
Technical field
The present invention relates to petroleum pipeline technical field, especially a kind of corrosion resistant petroleum pipeline.
Background technology
The system of laying of petroleum pipeline includes built on stilts laying and buried-pipe laying.When petroleum pipeline buried-pipe laying, can be subject to
Acid in soil, alkali, salt and other there is the infringement of corrosive substance, petroleum pipeline is after laying it should be ensured that pipeline is several
Ten years normally use, and do not occur to lead to pipeline breaking, oil leakage phenomenon because of corrosion, do well Ru anti-corrosion, the life-span of pipeline
Can greatly shorten, so during petroleum pipeline buried-pipe laying, must carry out anti-corrosion, particularly more should in saline and alkaline underground laying
Carry out petroleum pipeline anti-corrosion.
Content of the invention
The invention aims to solving the above problems, there is provided a kind of corrosion resistant petroleum pipeline.
The purpose of the present invention to implement by the following technical programs：
A kind of corrosion resistant petroleum pipeline, including the steel pipe of transfer oil, is followed successively by Epoxy coal drip from the inside to the outside in described outer wall of steel pipe
Blue or green resin bed, dcpd resin layer and polyethylene layer.
Further, the thickness of described epoxide coal bituminous resin bed is 1-1.5mm, the thickness of described dcpd resin layer
Spend for 0.8-1.5mm, the thickness of described polyethylene layer is 2-3mm.
Further, apply one layer of epoxide-resin glue between described epoxide coal bituminous resin bed and dcpd resin layer,
One layer of epoxide-resin glue is applied between described dcpd resin layer and polyethylene layer.
Beneficial effects of the present invention are：
The corrosion resistant petroleum pipeline that the present invention provides, alkaline resistance properties strong it is adaptable to buried-pipe laying in alkaline soil, the use of pipeline
Life-span reaches more than 50 years.
Brief description
Fig. 1 is the structure chart of corrosion resistant petroleum pipeline of the present invention.
In figure：1- steel pipe；The epoxide coal bituminous resin bed of 2-；3- epoxide-resin glue；4- dcpd resin layer；5- epoxy
Resin glue；6- polyethylene layer.
Specific embodiment
As shown in figure 1, corrosion resistant petroleum pipeline described in the embodiment of the present invention, including the steel pipe 1 of transfer oil, in described steel pipe
Outer wall first applies the thick epoxide coal bituminous resin bed 2 of 1-1.5mm, then applies epoxy glue layer 3, then applies the bicyclic of 0.8-1.5mm thickness
Pentadiene resin bed 4, then apply epoxy glue layer 5, finally apply the thick polyethylene layer 6 of 2-3mm.
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.
