Abstract

The utility model relates to a wear-resisting cold-resistant anticorrosive pipeline, including first pipeline and second pipeline, first pipeline is located the second pipeline and through a plurality of go-between fixed connection between first pipeline and the second pipeline, the inner wall and the outer wall of first pipeline, the surface of go-between and the inner wall of second pipeline all coat and have the anticorrosive coating, second pipeline outer wall is equipped with the cold-resistant layer of polyimide, the cold-resistant layer surface of polyimide is equipped with halogen-free flame retardant coating, halogen-free flame retardant coating outer surface is equipped with the metal mesh layer, the metal mesh layer surface is equipped with the silica gel wearing layer. The utility model discloses a two-layer pipeline that the go-between is connected makes the inner chamber of inner layer pipeline back transported substance material between two-layer pipeline flow after breaking, avoids the individual layer pipeline to break the loss that causes, and metal mesh layer and silica gel wearing layer make the wear-resisting and resistant destructiveness of pipeline obtain promoting simultaneously, and the cold-resistant layer of last polyimide can keep the temperature of pipeline body under chilly condition, avoids the pipeline frost crack.

Description

Wear-resistant and cold-resistant anti-corrosion pipeline

Technical Field

The utility model relates to an anticorrosive pipeline technical field especially relates to a wear-resisting cold-resistant anticorrosive pipeline.

Background

The pipeline of carrying oil, gas is most in complicated soil environment, and the medium of carrying also has corrosivity more, therefore pipeline inner wall and outer wall all can suffer to corrode, and the pipeline is very easy to be frozen apart under the environment of severe cold simultaneously, in case the pipeline is corroded the perforation, causes oil, gas leakage promptly, not only makes the transportation interrupt, can the polluted environment moreover, probably arouses the conflagration even, causes harm.

Disclosure of Invention

The utility model aims at solving the defects of the prior art and providing a wear-resistant and cold-resistant anti-corrosion pipeline.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:

the utility model provides a wear-resisting cold-resistant anticorrosive pipeline, includes first pipeline and second pipeline, first pipeline is located the second pipeline and through a plurality of go-between fixed connection between first pipeline and the second pipeline, the inner wall of first pipeline and the surface of outer wall, go-between and the inner wall of second pipeline all coat and have the anticorrosive coating, second pipeline outer wall is equipped with the cold-resistant layer of polyimide, the cold-resistant layer surface of polyimide is equipped with halogen-free flame retardant layer, halogen-free flame retardant layer outer surface is equipped with the metal mesh layer, the metal mesh layer surface is equipped with the silica gel wearing layer.

Particularly, the metal mesh layer is criss-cross metal wires formed by weaving.

The utility model has the advantages that: the utility model discloses a two-layer pipeline that the go-between is connected makes the inner chamber of inner layer pipeline back transported substance material between two-layer pipeline flow after breaking, avoids the individual layer pipeline to break the loss that causes, and metal mesh layer and silica gel wearing layer make the wear-resisting and resistant destructiveness of pipeline obtain promoting simultaneously, and the cold-resistant layer of last polyimide can keep the temperature of pipeline body under chilly condition, avoids the pipeline frost crack.

in the figure: 1-a first conduit; 2-a second conduit; 3-connecting rings; 4-an anticorrosive layer; 5-polyimide cold resistant layer; 6-a halogen-free flame retardant layer; 7-a metal mesh layer; 8-silica gel abrasion resistant layer;

Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, a wear-resistant and cold-resistant anticorrosive pipeline, includes first pipeline 1 and second pipeline 2, first pipeline 1 is located second pipeline 2 and passes through a plurality of go-between 3 fixed connection between first pipeline 1 and the second pipeline 2, the inner wall and the outer wall of first pipeline 1, the surface of go-between 3 and the inner wall of second pipeline 2 all coat and have anticorrosive coating 4, the outer wall of second pipeline 2 is equipped with the cold-resistant layer 5 of polyimide, the cold-resistant layer 5 surface of polyimide is equipped with halogen-free flame retardant layer 6, the outer surface of halogen-free flame retardant layer 6 is equipped with metal mesh layer 7, the outer surface of metal mesh layer 7 is equipped with silica gel wearing layer 8.

Specifically, the metal mesh layer 7 is a crisscross metal wire formed by knitting.

First pipeline 1 and second pipeline 2 through a plurality of go-between 3 fixed connection, can corrode liquid at go-between 3 after first pipeline 1 corrodes and break, flow in the inner chamber between first pipeline 1 and the second pipeline 2, avoid corroding the outside pollution that causes the environment of liquid outflow pipeline, the temperature of pipeline body can be kept under chilly condition in the setting of the cold-resistant layer 5 of polyimide, can not influence the quality of steel pipe body under the condition that the external temperature reduces, metal mesh layer 7 and silica gel wearing layer 8 make the wear-resisting and the resistant destructiveness of pipeline obtain promoting.

The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above embodiments, and various improvements made by the method concept and technical solution of the present invention or directly applied to other occasions without improvement are all within the protection scope of the present invention.
