With the acceleration of urbanization, the problem of sewage treatment has attracted more and more attention. As an important part of it, domestic sewage treatment is of great significance to ensure people's production and life. As a new type of pipeline material, plastic-coated steel pipe has gradually been widely used in domestic sewage treatment. This paper will elaborate on the characteristics, advantages, applications and development prospects of plastic-coated steel pipes for domestic sewage treatment.

First, the characteristics of plastic-coated steel pipes.
Plastic-coated steel pipe is a kind of pipe made of anti-corrosion materials such as polyethylene and epoxy resin on the surface of the steel pipe. Compared with traditional steel pipes, plastic-coated steel pipes have the following characteristics:
1.Strong corrosion resistance: The anti-corrosion material of plastic-coated steel pipe can effectively resist the erosion of various corrosive substances such as acid, alkali and salt, and significantly improve the service life of the pipeline.
2.Good environmental performance: the anti-corrosion material of plastic-coated steel pipe is non-toxic and tasteless, harmless to the environment, and meets the requirements of environmental protection.
3.Low fluid resistance: The inner wall of the plastic-coated steel pipe is smooth and not easy to accumulate fouling, which effectively reduces the fluid resistance and improves the fluid transportation efficiency.
4.Various connection methods: Plastic-coated steel pipes can be welded, flanged, clamped and other connection methods to facilitate construction and installation.
5.Low overall cost: Although the unit price of plastic-coated steel pipe is high, the overall cost is relatively low due to its long service life and low maintenance cost.
2. The advantages of plastic-coated steel pipes in domestic sewage treatment.
In domestic sewage treatment, the application of plastic-coated steel pipes has the following advantages:
1.Strong adaptability: Plastic-coated steel pipes can adapt to different soil conditions and ambient temperatures, and have strong durability and stability.
2.Reduced maintenance costs: Due to the strong corrosion resistance of plastic-coated steel pipes, the frequency of repairs and replacements of pipes can be reduced, thereby reducing maintenance costs.
3.Improve conveying efficiency: The inner wall of the plastic-coated steel pipe is smooth and not easy to accumulate fouling, which can effectively improve the efficiency of sewage transportation and reduce energy consumption.
4.Improve water quality: The plastic-coated steel pipe has good sealing and pressure resistance, which can ensure that the sewage does not leak and pollute the environment during the transportation process, and at the same time reduces the secondary pollution of water quality.
5.Easy installation: The connection methods of plastic-coated steel pipes are diverse, and the installation is simple and fast, which can shorten the project period and reduce the construction cost.
3. Application of plastic-coated steel pipes in domestic sewage treatment.
Plastic-coated steel pipes are widely used in the following fields in domestic sewage treatment:
1.Drainage pipes: Plastic-coated steel pipes can be used as drainage pipes for collecting and treating domestic sewage, rainwater, etc. It has good corrosion resistance, which can effectively extend the service life and reduce maintenance costs.
2.Inspection wells: Plastic-coated steel pipes can be used as materials for inspection wells, which is convenient for staff to inspect and maintain. Its excellent durability and stability can improve the service life of the inspection well.
3.Pumping station: The plastic-coated steel pipe can be used as the inlet and outlet pipe of the pumping station, which has the advantages of low fluid resistance and good pressure resistance. At the same time, its anti-corrosion performance can effectively resist the erosion of acidic substances inside the pumping station.
4.Sewage treatment plant: Plastic-coated steel pipes can be used as pipelines and equipment materials for sewage treatment plants to improve water quality and reduce secondary pollution to the environment.
5.Landscape Lake Water Conveyance: Plastic-coated steel pipes can be used in landscape lake water conveyance systems because of their good environmental performance. It can not only meet the requirements of water transportation, but also reduce the secondary pollution of water bodies.
Fourth, the development prospect of plastic-coated steel pipes.
With the increasing awareness of environmental protection and the acceleration of urbanization, plastic-coated steel pipe, as a new type of pipeline material, has broad development prospects. In the future, with the continuous progress of technology and the continuous expansion of application fields, the performance and quality of plastic-coated steel pipes will be further improved. At the same time, with the continuous increase of national policy support for the environmental protection industry, the market demand for plastic-coated steel pipes will be further expanded. Therefore, we have reason to believe that plastic-coated steel pipes will become one of the important materials in the field of domestic sewage treatment in the future.
