Abstract
The utility model relates to an embedded pipeline which belongs to the technical field of conveying pipelines for crude oil, natural gas or other liquids and gases. The embedded pipeline comprises a pipe body, wherein an adhesive layer is coated outside the pipe body; an anti-corrosive protective layer is arranged outside the adhesive layer; and the anti-corrosive protective layer consists of at least one of a bottom rubber layer, a functional rubber layer and a protective rubber layer. The embedded pipeline has good anti-corrosive property and low production cost.
Description
Technical field
The utility model belongs to the conveyance conduit technical field of crude oil, rock gas or other liquid and gas.
Background technique
According to international norm, buried metal pipeline all adopts the associating protecting method of anticorrosive coat and cathodic protection, and pipeline anticorrosion coating is the first road barrier, is directly connected to the antiseptic property and the service life of buried pipeline.
Outer anticorrosion early stage employing petroleum tar, coal tar enamel and the solvent-borne type of domestic long distance pipeline are epoxide coal bituminous.Because the continuous attention of national environmental pollution and enterprise employee health, petroleum tar, coal tar enamel or epoxide coal bituminous anticorrosion mode are by clinkery epoxy powder (FBE) and polyethylene three-layer composite structure (3PE) anticorrosion replacement at present.Because FBE and 3PE have advantages of good anticorrosion performance and stronger anti-mechanical deterioration ability, are used widely at home.But the site operation scratch resistance performance of FBE is poor, and 3PE cathode current shadoweffect makes it have a lot of problems when widely applying.
Summary of the invention
At the problem that prior art exists, the purpose of this utility model is to design the technological scheme that a kind of buried pipeline is provided, and this buried pipeline antiseptic property is good, and cost of production is low.
Described a kind of buried pipeline comprises body, it is characterized in that the body outsourcing covers to put adhesive layer, and the adhesive layer outsourcing covers puts corrosion protective covering, and described corrosion protective covering is made of the one deck at least in end rubber layer, functional layer rubber layer and the protection rubber layer.
Described a kind of buried pipeline is characterized in that rubber layer of the described end is the mixing glue-line of natural rubber, nitrile butadiene rubber and neoprene.
Described a kind of buried pipeline is characterized in that rubber layer thickness of the described end is 1-2mm.
Described a kind of buried pipeline is characterized in that described functional layer rubber layer is butyl rubber layer, butyl rubber layer or butyl rubber bromide glue-line.
Described a kind of buried pipeline is characterized in that described functional layer rubber layer thickness is 1.5-2.5mm.
Described a kind of buried pipeline is characterized in that described protection rubber layer is neoprene layer or chlorosulfonated polyethylene rubber layer.
Described a kind of buried pipeline is characterized in that described protection rubber layer thickness is 2-3mm.
Described a kind of buried pipeline is characterized in that the outer sulfuric horizon that is provided with by the nylon cloth sulfuration of described corrosion protective covering.
Above-mentioned a kind of buried pipeline, simple in structure, reasonable in design, winding technology is extruded in utilization continuously and the MULTILAYER COMPOSITE technology is provided with the corrosion protective covering that is made of end rubber layer, functional layer rubber layer and protection rubber layer on body.Buried pipeline of the present utility model is compared with existent technique, has following advantage:
1) can change structural adhesive layer and glue-line prescription arbitrarily, for multiple industrial use pipeline provides good designability;
2) utilize the good workability of rubber, even the pipeline outside has stiffening rib also can guarantee the corrosion protective covering zero defect of producing;
3) because the elasticity of rubber and good physical and mechanical properties, corrosion protective covering has the characteristic of excellent crashproof, scratch proof, anti-stab, antifreeze, high-low temperature resistant, constructs under the various geological conditions pipeline with burying and brings convenience;
4) corrosion protective covering has good recoverability, but the reparation of small size damage field condition does not need special equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: the 1-body; The 2-adhesive layer; Rubber layer at the bottom of the 3-; 4-functional layer rubber layer; 5-protects rubber layer.
Embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure, a kind of buried pipeline comprises body 1, and body 1 has metallic material to make, on the outer surface of body 1, coat adhesive layer 2 is set, adhesive layer 2 is made of the Bond of brushing, and Bond is a kind of commodity Bond, can adopt the Kai Muluoke that sells on the market, ROHM AND HAAS etc.Adhesive layer 2 outsourcings cover puts corrosion protective covering, and corrosion protective covering can be made of the one deck at least in end rubber layer 3, functional layer rubber layer 4 and the protection rubber layer 5.Therefore can outside adhesive layer 2, only coat the one deck that is provided with in end rubber layer 3, functional layer rubber layer 4 or the protection rubber layer 5; can cover two-layer arbitrarily in bottom set rubber layer 3, functional layer rubber layer 4 or the protection rubber layer 5 in adhesive layer 2 outsourcings, also can adhesive layer 2 outside, coat successively and end rubber layer 3, functional layer rubber layer 4 are set and protect rubber layer 5.
End rubber layer 3 is the mixing glue-line of natural rubber, nitrile butadiene rubber and neoprene, and its thickness is 1-2mm, and it mainly acts on is to combine with adhesive layer 2, and effects such as buffering are provided.
Functional layer rubber layer 4 is butyl rubber layer, butyl rubber layer or butyl rubber bromide glue-line, and thickness is 1.5-2.5mm, and best thickness is 2mm.Functional layer rubber layer 4 mainly is to prevent that water and various corrosivity electrolytic solution in the outside landfill material from infiltrating end rubber layer 3, plays the effect of isolating exterior environment.
Protection rubber layer 5 is neoprene layer or chlorosulfonated polyethylene rubber layer, and thickness is 2-3mm.Mainly play a protective role, the one, collision, scraping in the loading and unloading transportation process; The 2nd, the bump in the landfill process, extruding, scraping; The 3rd, store transportation, bury the aging corrosion of spreadable life behind the ground.
Can evenly wrap up one deck nylon cloth on its outer surface after corrosion protective covering is wrapped, be placed on the enterprising cylinder sulfuration of sulfuration car, constitute sulfuric horizon after the sulfuration, take off nylon cloth then, packing becomes finished product.
Buried pipeline of the present utility model is ageing-resistant, corrosion-resistant, anti-collision, repairing performance are good, and glue-line is to metallic conduit cohesive force height, and long-term use can not peeled off.
Shown in the above and the figure only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
