2.Good insulation: The three-layer polyethylene anti-corrosion layer has excellent insulation properties, which effectively reduces the risk of electrochemical corrosion of the pipeline.
3.Excellent anti-aging performance: The three-layer polyethylene anti-corrosion layer adopts advanced production technology, which has good anti-aging performance and ensures the long service life of the pipeline.
4.Environmental protection and safety: The three-layer polyethylene anticorrosive spiral steel pipe is non-toxic and tasteless, harmless to the environment, and meets national environmental protection standards.
5.Easy installation: The three-layer polyethylene anticorrosive spiral steel pipe is light in weight and easy to transport and install, reducing the difficulty and cost of the project.
3. Production process of three-layer polyethylene anticorrosive spiral steel pipe.
The production process of three-layer polyethylene anticorrosive spiral steel pipe mainly includes the following steps:
1.Steel pipe rust removal: remove the oxide scale, oil stain and impurities on the surface of the steel pipe to ensure the adhesion of the anti-corrosion layer.
2.Spraying primer: spray a layer of primer with strong adhesion and good anti-rust performance on the surface of the steel pipe to improve the adhesion between the anti-corrosion layer and the steel pipe.
3.Production and coating of polyethylene anti-corrosion layer: high-temperature melt extrusion technology is used to evenly coat the polyethylene material on the surface of the steel pipe to form a dense anti-corrosion layer.
4.Temperature resistance test: The temperature resistance test is carried out on the coated steel pipe to ensure that it can work normally within the specified temperature range.
5.Quality inspection and packaging: Carry out quality inspection on qualified steel pipes, such as appearance, thickness, adhesion, etc., and finally package them out of the factory.
