Polyethylene insulation steel pipe
Polyethylene thermal insulation steel pipes are lightweight, high-strength, and highly resistant to corrosion, making them an ideal non-metallic piping solution. These pipes are manufactured by winding a glass fiber-reinforced resin matrix around a rotating mandrel according to specific process requirements. A layer of quartz sand is evenly distributed between the fibers to enhance structural integrity. The resulting wall structure is both rational and advanced, maximizing the performance of the materials used. This design ensures high rigidity while maintaining the required strength, thus guaranteeing the product's stability and reliability.
Due to its excellent resistance to chemical corrosion, light weight, high strength, and long service life, this type of pipe has gained widespread acceptance among users. Compared to conventional steel pipes, it offers advantages such as no scaling, strong impact resistance, lower overall costs, faster installation, and higher reliability.
**Key Performance Features of High-Density Polyethylene Thermal Insulation Steel Pipes:**
1. High-performance rigid polyurethane foam is used as the insulation material, offering low thermal conductivity and superior thermal insulation properties.
2. When transporting water at 130°C over a distance of 40 kilometers, the temperature drop is only about 1°C, demonstrating exceptional thermal efficiency.
3. The pipes are highly waterproof and corrosion-resistant, eliminating the need for additional pipe trenches. They can be directly buried underground or underwater, simplifying construction and reducing overall costs.
4. They also exhibit excellent corrosion and impact resistance in low-temperature environments, allowing direct burial in permafrost layers.
5. The outer casing is made from high-density polyethylene (HDPE), which is resistant to biological and chemical corrosion.
6. Customized options are available, including various pipe diameters ranging from DN20 to DN1200 and adjustable insulation thicknesses, along with matching fittings like elbows, tees, reducers, and fixed joints.
7. The product complies with industry standards for urban construction, ensuring quality and safety.
8. To ensure optimal performance, the outer surface of the steel pipe undergoes shot blasting before foaming, while the inner surface of the plastic pipe is treated with corona discharge. Surface tension is maintained at 50 dynes/cm, meeting strict quality requirements.
9. Made from high-density polyethylene and enhanced with additives such as antioxidants, the raw materials and finished products are thoroughly tested to meet the CJ/114-2000 standard and technical specifications for buried pipelines. Detailed technical parameters are provided in the table below.
10. The company utilizes both imported and domestic high-pressure foaming machines and hydraulic pipe threading equipment, further enhancing product quality and performance.
These features make high-density polyethylene thermal insulation steel pipes a reliable and cost-effective choice for a wide range of industrial and municipal applications.
