Description
Technical Field
The invention relates to the field of pipeline corrosion prevention, in particular to a natural gas pipeline corrosion prevention method.
Background
The gas pipeline is mainly made of carbon steel materials, and the conveyed gas contains a small amount of corrosive impurities such as water, carbon dioxide, hydrogen sulfide gas and the like, so that the inner wall of the pipeline is corroded after long-time action; the outside of the buried pipeline is corroded due to the action of water, acid, alkali, salt, mineral substances, microorganisms and stray current in soil; corrosion of pipelines causes damage to equipment and accidents, such as fire, explosion, gas leakage, etc., and besides economic loss and environmental damage, life is sometimes injured, so that high attention must be paid to corrosion.
At present, the common method for pipeline corrosion prevention is to add an anticorrosive coating and add cathodic protection, the common external anticorrosive coating is mainly a three-layer polyethylene anticorrosive coating (3PE), but the adhesion between the anticorrosive coating and the outer wall of the pipeline is not enough, so that the anticorrosive coating falls off, and the corrosion of the steel pipe is accelerated; therefore, the pipeline can be additionally provided with a cathode protection device, so that the corrosion of the protected pipeline is slowed down as a cathode in the electrochemical cell, but the cathode protection effect is difficult to achieve due to the problems of improper installation, improper maintenance of the test pile and the like, and the installation and maintenance cost is high.
Disclosure of Invention
The invention aims to provide an underground gas pipeline anticorrosion method which has the advantages of good anticorrosion effect, low use cost, cathode protection effect and internal and external anticorrosion aiming at the defects of the prior art.

(1) and polishing, cleaning and drying the inner surface of the pipeline, uniformly coating a second graphene primer coating on the inner surface of the pipeline with the thickness of 0.05mm, coating a second graphene finish coating on the second graphene primer coating with the thickness of 0.1mm after a period of time, and finally curing at room temperature to form the inner anticorrosive coating of the pipeline. (2) Polishing, cleaning and drying the outer surface of the pipeline, uniformly coating the first graphene primer coating on the outer surface of the pipeline with the thickness of 0.05mm, coating the first graphene finish coating on the first graphene primer coating with the thickness of 0.1mm after a period of time, then adding a polyethylene protective layer on the second graphene finish coating with the thickness of 1.5mm, and finally curing at room temperature to form the outer-pipeline anticorrosion coating.
The preparation method of the graphene primer coating comprises the following steps: uniformly stirring fillers such as epoxy resin, zinc powder and graphene powder in a dispersing device according to a certain proportion, then adding other auxiliaries and solvents, grinding to a certain fineness by using a grinder, and filtering to obtain the graphene primer coating;
the preparation method of the graphene finish paint comprises the following steps: uniformly stirring epoxy resin, mica iron oxide and graphene powder filler in a dispersing device according to a certain proportion, then adding other auxiliaries and solvents, grinding to a certain fineness by using a grinding machine, and filtering to obtain a finish paint;
the graphene primer coating comprises the following components: 25-35 parts of epoxy resin, 30-50 parts of zinc powder, 1-2 parts of graphene powder and 15-20 parts of other auxiliaries and solvents;
the graphene finish paint comprises the following components: 35-45 parts of epoxy resin, 20-40 parts of mica iron oxide, 1-3 parts of graphene powder and 20-30 parts of other auxiliaries and solvents;
the thickness of the graphene primer coating is 0.05-0.06mm, the thickness of the graphene finish coating is 0.1-0.2mm, and the thickness of the polyethylene protective layer is 1-2 mm;
the invention has the beneficial effects that:
(1) the graphene primer coating is doped with zinc powder with the self-corrosion potential more negative than that of the metal pipeline, and the zinc powder contained in the coating is preferentially corroded as an anode in the corrosion process, so that the generation and development of the corrosion reaction of the metal pipeline are delayed, and the metal pipeline is effectively protected;
(2) the graphene primer coating and the graphene finish coating have better comprehensive protection performance, and can effectively improve the physical shielding effect and isolate corrosive media (such as water, oxygen, salt mist and the like) from protected metal, thereby preventing the formation of a corrosion battery or inhibiting the diffusion of the corrosion battery;
(3) the polyethylene protective layer can protect the external coating of the pipeline, and the damage of the graphene coating caused by artificial factors in the pipeline installation process is effectively reduced;
(4) the method has the advantages that the anticorrosive layer is arranged inside and outside the pipeline, the pipeline protection effect is improved, the corrosion is reduced, the anticorrosive effect is enhanced, the use cost is reduced, and the practicability is high.
