With the development of my country's economy, technological progress and urban construction, the importance of pipeline transportation has been widely recognized. The role of pipelines has become increasingly prominent, and transportation media has become increasingly diversified. Among them, pipeline perforations caused by corrosion of deep-buried steel pipes are more frequent. At this time, pipeline anti-corrosion work must be done in advance to extend the service life of pipeline anti-corrosion, protect production safety and save money. Do you know the process and advantages of anti-corrosion pipelines?

What are the requirements for the anti-corrosion layer of the anti-corrosion pipeline?

1. The anti-corrosion layer of underground pipelines is not easy to repair. In order to ensure the service life of the pipeline, the anti-corrosion layer has a long anti-corrosion life.
2. The selected coating should have excellent rust resistance, permeability and moisture resistance. Considering that the pipeline may cross contaminated soil or rivers, the coating should also have good chemical resistance.
3. The coating should be able to resist the penetration of plant root diameter.
4. Considering the needs of equipment and transfer, anticorrosion should have good wear resistance, scratch resistance and firmness.

The steps of the pipeline corrosion protection steps

The anti-corrosion of the steel pipe is according to the requirements of the drawing. The epoxy coal tar paint is used to wrap the glass cloth, and the outer wall is coated with the top paint. The construction process of the outer wall is: pipe derusting → primer coating → first pass top coat → second pass top coat → wrapped glass cloth →finish paint→finish paint; inner wall construction process: pipe derusting→primer paint→first finish finish→second finish finish→third finish finish

Advantages of anti-corrosion pipeline in practical application

1. The anticorrosive pipeline has a long service life. After ordinary steel pipes are treated with anticorrosion, the service life of ordinary steel pipes can be as long as 20-30 years or longer. It can be called "life" in the pipeline, which can save the cost of replacement and maintenance.
2. The anti-corrosion pipeline construction is simple and quick, and can be carried out in the factory and on-site. Compared with ordinary steel pipes, the construction of anti-corrosion steel pipes is very simple, there is no main equipment and site, and the on-site operation is very suitable. During the construction process, anti-corrosion can be performed on one side of the site at the same time.
3. The anti-corrosion pipeline project is cheap and economical. Combining the quality and service life of steel pipes, its service life and investment can reach a reasonable ratio, which is more economical and applicable than old steel pipes. It is also an important factor for people to buy.
4. The anti-corrosion pipeline design is centered on environmental protection. Today, this design is more in line with the needs of the times. In the future, fluid transportation pipelines will have stricter requirements for environmental protection, and products that cannot be developed with the environmental protection of the times will eventually be eliminated.

The above is the relevant introduction on the anti-corrosion of anti-corrosion pipelines. Old steel pipes will be eliminated in engineering use. Anti-corrosion pipelines will occupy an increasingly important proportion in the future market development. Pipeline construction in the future will be the main force.
