Plastic-coated steel pipe is a new type of steel pipe material, which has the characteristics of excellent corrosion resistance, environmental protection and non-toxicity, light and durable, smooth internal and external surfaces, etc., and is widely used in water supply, drainage, fire protection, petroleum, chemical industry and other fields. Among them, the plastic-coated steel pipe with a diameter of 1620*16 is a large-diameter pipe material, which is particularly widely used in the field of water supply. Plastic-coated steel pipes for water supply
First, the characteristics of plastic-coated steel pipes.
1.Strong corrosion resistance: The outer surface of the plastic-coated steel pipe is coated with organic materials such as polyethylene and polyvinyl chloride, which have good corrosion resistance, which can effectively prevent the pipeline from being affected by soil, air, water and other media, and prolong the service life of the pipeline.
2.Environmentally friendly and non-toxic: The material of the plastic-coated steel pipe is environmentally friendly and non-toxic, will not cause harm to the environment and the human body, and meets the requirements of national environmental protection regulations.
3.Lightweight and durable: The plastic-coated steel pipe is light in weight, easy to install and handle, and has good impact resistance and compressive strength, which can meet the high pressure requirements of water supply pipelines.
4.Smooth internal and external surfaces: The internal and external surfaces of plastic-coated steel pipes are smooth, not easy to accumulate dirt and bacteria, easy to clean and disinfect, and ensure the cleanliness and hygiene of the pipeline.
Second, the application of 1620*16 diameter plastic-coated steel pipe.
As a large-diameter pipe material, plastic-coated steel pipe with a diameter of 1620*16 is particularly widely used in the field of water supply. It can meet the needs of large flow of feed water, and has excellent pressure resistance and corrosion resistance, which can ensure the safety and stability of feed water.
In urban water supply projects, plastic-coated steel pipes can effectively prevent pipelines from being affected by groundwater and soil, and ensure the quality and safety of water supply. At the same time, the inner surface of the plastic-coated steel pipe is smooth, not easy to accumulate dirt and bacteria, which can ensure the cleanliness and hygiene of the pipeline and meet the requirements of national health standards.
In the fields of petroleum and chemical industry, plastic-coated steel pipes have also been widely used. Due to its excellent corrosion resistance and compressive strength, it can meet the requirements of fluid transportation in various complex environments. At the same time, the material of the plastic-coated steel pipe is environmentally friendly and non-toxic, will not cause harm to the environment and the human body, and meets the requirements of national environmental protection regulations.
3. Production process of plastic-coated steel pipe.
The production process of plastic-coated steel pipe mainly includes the following steps:
1.Pretreatment: Pretreatment such as derusting and degreasing the steel pipe to ensure the adhesion and service life of the coating.
2.Coating: Electrostatic spraying or other coating methods are used to coat organic materials on the outer surface of steel pipes.
3.High-temperature curing: The coating is heated to a certain temperature to form a tightly bonded coating with the surface of the steel pipe.
4.Testing: Thickness testing, adhesion testing, compressive strength testing and other testing of the coating are carried out to ensure the quality and safety of the product.
Fourth, the development trend of plastic-coated steel pipes.
With the continuous development of science and technology, as a new type of steel pipe material, the development trend of plastic-coated steel pipe is becoming more and more obvious. In the future, plastic-coated steel pipes will pay more attention to environmental protection and health performance, and continue to develop more environmentally friendly, safe and durable new products. At the same time, with the continuous development of intelligent manufacturing technology, the production process of plastic-coated steel pipes will also be continuously upgraded and improved to improve production efficiency and quality level.
In short, as a large-diameter pipe material, the plastic-coated steel pipe with a diameter of 1620*16 has a wide prospect and important significance in the field of water supply. In the future, plastic-coated steel pipes will continue to give full play to their excellent performance and advantages, and make greater contributions to the development of water supply projects and other fields in China.
