Anti-corrosion steel pipe is buried in the underground metal body, but due to the use of environmental reasons, despite careful construction, the general steel pipe is inevitably easy to aging, the steel pipe will still have some damage defects, and in order to extend the life of the steel pipe, we must set up on the outside of the steel pipe corrosion prevention layer (Anticorrosion layer). In the actual pipeline use process, anti-corrosion steel pipe a variety of models to choose from, a variety of steel pipe, although the type is different, but each has its own different advantages, in the future development will be based on anti-corrosion type. Because the anti-corrosion steel pipe in the construction and practical application has the following four major advantages:
1. Simple construction, quick steps, in the factory and on-site construction site can be carried out. Anti-corrosion steel pipe construction is very simple compared to the old time steel pipe, without major equipment and sites, the site is very suitable for operation, can be in the field while construction process at the same time anti-corrosion.
2. longer life, ordinary steel pipe has a certain life expectancy, when the ordinary material for anti-corrosion treatment, its life expectancy can be as long as 20-30 years or longer, can be called the pipeline in the "longevity", the use of the replacement of the maintenance and other costs are saved.
3. the project cost is cheap and economic. In the case of steel pipe quality and life combination of comparison, service life and investment can reach a reasonable proportion, more economical than the old pipeline, which is also an important determinant of people's procurement.
4. anti-corrosion steel pipe to environmental protection as the centre of design ideas. In today's green environmental protection, this design is more in line with the needs of the times, in the future for the carrier of the fluid transport pipeline, environmental protection requirements will become more and more stringent, can not follow the times of environmental protection and development of products will eventually be eliminated.
