Polyethylene thermal insulation steel pipe is a modern, lightweight, high-strength, and corrosion-resistant non-metallic piping solution. It is manufactured by winding a glass fiber-reinforced resin matrix around a rotating mandrel in layers according to specific process requirements. A layer of quartz sand is evenly distributed between the fibers to enhance structural integrity. The tube wall design is both rational and advanced, allowing for optimal material performance. This ensures that the product maintains high rigidity while meeting all strength requirements, guaranteeing stability and reliability.
Due to its excellent resistance to chemical corrosion, light weight, high strength, no scaling, strong impact resistance, and long service life—compared to traditional steel pipes—this type of pipe has gained widespread acceptance among users. It also offers a low overall cost, quick installation, and reliable performance, making it an ideal choice for various applications.
Performance characteristics of high-density polyethylene (HDPE) thermal insulation steel pipe include:
1. It uses rigid polyurethane foam as the thermal insulation material, which has a low thermal conductivity and provides superior insulation properties.
2. When transporting water at 130°C over a distance of 40 kilometers, the temperature drop is only about 1°C, demonstrating excellent thermal efficiency.
3. The pipe offers strong waterproofing and corrosion resistance, eliminating the need for additional trenching. It can be directly buried underground or underwater, simplifying construction and reducing overall costs.
4. It performs well under low-temperature conditions, with good corrosion and impact resistance, allowing it to be buried in permafrost regions.
5. The outer casing is made of corrosion-resistant high-density polyethylene (HDPE), which is immune to biological and chemical degradation.
6. Custom sizes ranging from DN20 to DN1200 are available, along with matching fittings such as elbows, tees, reducers, and fixed joints, tailored to user requirements.
7. The product complies with industry standards for urban construction, ensuring quality and safety.
8. To ensure the quality of three-dimensional HDPE thermal insulation steel pipes, the outer surface of the steel pipe undergoes shot blasting before foaming, and the inner surface of the plastic pipe is treated with corona discharge. These processes meet strict rust removal and surface tension requirements, with the inner surface tension reaching 50 dynes/cm.
9. The pipe is made from high-density polyethylene material, enhanced with additives like antioxidants. Raw materials and finished products are rigorously tested to meet the CJ/114-2000 standard and technical specifications for buried pipe outer protection. 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, significantly improving product quality and consistency.
This innovative piping system is not only durable and efficient but also environmentally friendly, making it a preferred choice for modern infrastructure projects. Whether used in heating systems, industrial pipelines, or municipal utilities, it delivers long-term value and performance.
