Polyethylene insulation steel pipe
Polyethylene thermal insulation steel pipes are a type of lightweight, high-strength, and corrosion-resistant non-metallic piping system. They are manufactured by winding a glass fiber-reinforced resin matrix layer by layer onto a rotating mandrel according to specific process requirements. A layer of quartz sand is evenly spread between the fibers to enhance structural integrity. This advanced wall structure optimizes material performance, ensuring both strength and rigidity while maintaining product stability and reliability. Due to its excellent chemical resistance, light weight, high strength, no scaling, strong impact resistance, long service life, low overall cost, fast installation, and reliable performance, this type of pipe has gained widespread acceptance among users.
**Performance Characteristics of High-Density Polyethylene Thermal Insulation Steel Pipes:**
1. The thermal insulation material used is rigid polyurethane with low thermal conductivity, offering excellent 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 superior heat retention.
3. These pipes have strong waterproofing and corrosion resistance, eliminating the need for additional pipe trenches. They can be directly buried underground or underwater, making installation simple, fast, and cost-effective.
4. They also exhibit good corrosion and impact resistance under low-temperature conditions, allowing them to be directly buried in permafrost areas.
5. The outer casing is made of high-density polyethylene (HDPE), which is resistant to biological and chemical corrosion.
6. The pipes are available in various diameters from DN20 to DN1200, with customizable insulation thicknesses and matching fittings such as elbows, tees, reducers, and fixed joints, tailored to user needs.
7. The product complies with urban construction industry standards, ensuring quality and safety.
8. To ensure the quality of three-dimensional high-density polyethylene thermal insulation steel pipes, the outer surface of the steel pipe is shot-blasted before foaming, and the inner surface of the plastic pipe undergoes corona treatment. Rust removal meets strict requirements, and the surface tension of the outer shell reaches 50 dynes/cm.
9. Made from high-density polyethylene and enhanced with additives like antioxidants, the raw materials and finished products undergo rigorous inspection to meet the CJ/114-2000 standard and technical requirements for buried pipe protection. Detailed technical specifications are provided in the table below.
10. The company uses both imported and domestic high-pressure foaming machines and hydraulic pipe threading machines, significantly improving product quality and performance.
These features make high-density polyethylene thermal insulation steel pipes an ideal solution for modern heating and insulation systems, offering durability, efficiency, and cost-effectiveness. Whether in residential, commercial, or industrial applications, they provide a reliable and long-lasting alternative to traditional steel pipes.
