Description
Technical field
The present invention relates to pipeline corrosion protection field more particularly to the pipeline corrosion protection fields of wet environment.
Background technique
When carrying out remote liquid or gas transport, pipeline transportation is often used, and during transportation, pipeline buries more
It in underground, and needs across different zones, the roughing-in in different underground environments, this is no small challenge to pipeline.Cause
For, there are the source of corrosion that a variety of pairs of pipelines have corrosiveness, stray electrical current, microorganism, acid, alkali, salt etc. all can be rotten in underground environment
Pipeline is lost, so that the electrochemical corrosion of oxygen uptake burn into, hydrogen sulfide corrosion, bacterial corrosion etc. occur for pipeline.
Moist underground environment is especially obvious to the corrosion of pipeline, there is a large amount of moisture in wet condition, these water
Divide so that acid, alkali, salt can form solution, mobility is stronger, and also more closely, chemical property is being dissolved in water to the contact with pipeline
What is also showed afterwards is more abundant, and corrosivity is stronger.For wet environment more favorably with the growth of microorganism, microbial activity is stronger, rotten
Corrosion is also with increase.Damp soil resistance is smaller, and propagation resistance is just smaller in the soil for stray electrical current, and current strength is more
Greatly, it is easier to enter pipeline, when flowing through pipeline caused by corrosion failure it is also even more serious.Wetland is more slack and undisciplined, by
External force easily deforms, is recessed, can be gradually recessed under the long term of pipeline gravity, so that pipeline settles, increases
The shear stress of pipeline, or even damage pipeline.
Various corrosion can be all enhanced in wet condition, so that pipeline receives more serious damage, but stray electrical current exists
Corrosiveness enhancing under wet environment is the most obvious, and not only current strength is influenced to significantly increase by slowly drained soil, Er Qie electricity
Stream itself is propagated rapidly, and electrochemical corrosion itself is also more rapider and stronger to the corrosivity of pipeline than other corrosion, therefore
When pipeline is by moist underground environment, need that corresponding measure is taken to reduce electrochemical corrosion.
Existing corrosion-proof technology for pipeline application is wide, but does not have specific aim, and anti-corrosion effect is less desirable, especially
It is for electrochemical corrosion caused by stray electrical current in wet environment, without corresponding specific aim measure.
Summary of the invention
The problem of corroding present invention aim to address pipeline in wet environment, especially stray electrical current causes electrification
The problem of learning corrosion, provide it is a kind of it is with strong points, Corrosion Protection is good, high reliablity, construction technology are easy, humidity at low cost
The pipeline corrosion protection structure and anti-corrosion method of environment.
A kind of the technical solution adopted in the present invention: pipeline corrosion protection structure of wet environment, comprising: pipeline, pedestal, insulation
Erosion resistant coating, metal mesh, waterproof insulating layer;
Pedestal described further is formed by concreting, is located at below pipeline, is primarily served supporting pipeline, separate pipeline
With lower section wet environment, while increasing forced area, avoids effect of the pipeline by gravitational settling;
Further, the insulating corrosion layer is made of natural rubber by chemical industry vulcanizing treatment, is located at pipeline periphery, is close to
Pipeline wall surface, does not interspace, and not only has good insulating properties, but also corrosion-resistant, has both anti-corrosion and insulation function;
Further, the metal mesh is wrapped on insulating corrosion layer, is close to insulating corrosion layer, metal mesh is by anti-corrosion
Reason, surface is coated with anticorrosive paint;
Further, by non-conductive fibre product as ground, leaching is made the waterproof insulating layer with insulated paint, is located at metal mesh
Outside, metal mesh is closely clipped in the middle together with insulating corrosion layer, the waterproof insulating layer has certain mechanical strength, and insulate
Property is good, while moisture-resistance is strong, has both insulation and water-proof function.
A kind of pipeline corrosion protection method of wet environment of the present invention is as follows:
(1) it pours pedestal: in the pipeline groove excavated, along channel bottom, going out to place pipeline institute with concreting
The pedestal needed;
(2) line treatment: integrally carrying out cleaning treatment to pipeline, by the rusty stain, greasy dirt, dust of pipeline surfaces externally and internally, this
The substance unfavorable to pipeline is removed a bit;
(3) insulating corrosion layer is set: insulating corrosion layer being close to pipeline setting, it is made not have gap between pipeline;
(4) it winds metal mesh: preservative treatment being carried out to metal mesh, metal mesh is dipped in anticorrosive paint, keeps metal mesh each
Anticorrosive paint is sufficiently smeared on a surface, does not stay dead angle, and then metal mesh is tightly wound around on insulating corrosion layer;
(5) waterproof insulating layer is set: waterproof insulating layer being arranged in outside metal mesh, it is made tightly to wrap metal mesh, it will
Metal mesh is clamped between waterproof insulating layer and insulating corrosion layer.
Beneficial effects of the present invention: (1) concreting at pedestal pipeline and lower section wet environment are separated, reduce
Influence of the wet environment to corrosive pipeline, while increasing forced area, avoid pipeline by gravitational settling;(2) natural rubber chemical industry
The insulating corrosion layer formed after processing had not only had good insulating properties, but also corrosion-resistant, the electrification that can prevent stray electrical current from being formed
Corrosion is learned, and is avoided that other kinds of corrosion;(3) waterproof insulating layer except insulation in addition to can also humidity, reduce wet environment
Influence to corrosion;(4) double hyer insulation makes stray electrical current be difficult to flow directly into pipeline, and the presence of metal mesh be capable of forming it is quiet
Electrical shielding reduces influence of the electric field of electric current flowing formation in soil to pipeline whereby.
