Description
Technical field
The utility model relates to pipeline corrosion protection field more particularly to Sandwich pipeline corrosion-resistant fields.
Background technique
Currently, underground is embedded in for transfer oil, natural pipeline, by these conveyance conduits, so that people live more
More convenient, therefore petrochemical industry, natural gas and some industrial circles are also facilitated in substance transportation aspect, so that industry
Have a long-range development, but pipeline bring it is convenient with development while also to face it is some must solve the problems, such as, by
Be embedded in underground in pipeline, and pipeline distance, the buried time is long, maintenance is inconvenient more, and the arrangement of pipeline can across it is various not
With the area of soil environment, need to cope with various complex environments, the corrosion condition of pipeline is by no small challenge.
Mainly having for corrosion factor: the corrosion of stray electrical current, microorganism, acid, alkali, salt etc. is caused to pipeline, it is therefore desirable to
Prevent pipeline from occurring the electrochemical corrosion of oxygen uptake burn into, hydrogen sulfide corrosion, bacterial corrosion etc., the corrosion of pipeline be threat tube just
The greatest problem often conveyed, if effectively cannot prevent or fail to handle corrosion in time, it will lead to pipe perforation, gently then cause
It conveys goods and materials to be lost, ambient contamination, burning even explosion that is heavy then causing conveying goods and materials occurs injury accident, leads to people
Member's injures and deaths and property loss, it is therefore necessary to take measures to prevent the generation of corrosive pipeline.
Current existing corrosion-proof technology for pipeline has: anticorrosion with painting coating, setting insulating layer, installation protective layer etc., these pipes
Although road anti-corrosion measure plays certain protective effect, so that the service life of pipeline is ensured to a certain extent,
But anti-corrosion effect is not fine, for example when facing the stray electrical current that corrosion is maked an inspection tour the most, effect is poor, therefore is badly in need of now
A kind of better pipeline corrosion protection measure of anti-corrosion effect solves the etching problem of pipeline.
Utility model content
The purpose of this utility model is to solve the problems, such as that pipeline when goods and materials transport is carried out using pipeline to be corroded, and is mentioned
For one kind is at low cost, applied widely, Corrosion Protection is good, high reliablity Sandwich pipeline anti-corrosive apparatus.
Technical solution adopted by the utility model: a kind of Sandwich pipeline anti-corrosive apparatus, comprising: interior conduit, channel rubber,
Interlayer system is collectively formed in casing, erosion resistant coating, protective layer, said inner tube road, channel rubber and casing；The channel rubber is by rubber
Glue is constituted, and is located at outside interior conduit, and interior conduit is close to, and insulation performance is good and corrosion-resistant；Described sleeve pipe is metal tube, is located at rubber
Outside interlayer, the space for placing channel rubber is collectively formed with interior conduit, described sleeve pipe is close to channel rubber；The erosion resistant coating is anti-
Rotten coating is applied to sleeve surface, repeatedly sprays repeatedly, forms fine and close dope layer；The protective layer is wrapped on the outside of erosion resistant coating,
The protective layer is made of rubber material, has certain flexibility and elasticity, can prevent to lead due to vibration or other physical impacts
The interior conduit and casing damage of cause.
Preferably, the channel rubber is poured by the rubber under molten condition.
Preferably, the axle center of said inner tube road and casing is same axle center.
Detailed process is as follows for a kind of Sandwich pipeline anti-corrosive apparatus of the utility model:
(1) interior conduit and casing clean: cleaning interior conduit and casing, removes rusty stain and the dirt of its surfaces externally and internally
Object avoids it from causing to corrode；
(2) channel rubber is set: watering the rubber of molten condition in the outer surface of interior conduit, before rubber solidification, will be covered
Pipe sleeve continues the rubber that the region between interior conduit and casing pours into molten condition outside interior conduit and molten rubber, it is ensured that
Interior conduit and casing are full of rubber, and casing and interior conduit are same axle center, form channel rubber after rubber is cooling；
(3) spraying corrosion resistant coating: anticorrosive paint is sprayed at bushing outer surface, is repeatedly sprayed, and angle from different directions
Degree is sprayed, and fine and close erosion resistant coating is ultimately formed；
(4) packing protective layer: protective layer is wrapped in outside erosion resistant coating, and by the elasticity of protective layer, protective layer is tightly pasted
In anti-corrosion layer surface.
The step of specific implementation (two), puts on casing after molten rubber is tentatively watered in the outer surface of interior conduit, and
The position of casing and interior conduit is primarily determined, then proceedes to pour into molten rubber, should guarantee casing and interior conduit it
Between be full of rubber tight, also to ensure that casing is identical as interior conduit axle center and avoid the occurrence of eccentric shaft.
The utility model has the beneficial effects that the system that (1) is collectively formed by casing, channel rubber and interior conduit, both had
The rigidity of standby casing is but also with channel rubber flexibility, so that interior conduit not only can guarantee the stability of structure when conveying goods and materials, but also
Physical impact and vibration can be coped with；(2) channel rubber avoids contact and stray electrical current of the corrosive substance with interior conduit
It flows into, while casing is metal material, interior conduit surrounds in the inner, forms protective layer, and field effect is avoided to cause interior conduit electric
Stream；(3) even if local corrosion occurs in casing, the function of stopping electric field can be still played, therefore reliability and stability are higher；(4)
Material therefor is simple and easy to get, has sale in the market, and cheap, cost is relatively low.
