Polyethylene thermal insulation steel pipe is a lightweight, high-strength, and corrosion-resistant non-metallic piping system. It is manufactured by winding a glass fiber-reinforced resin matrix onto a rotating mandrel according to specific process requirements. A layer of quartz sand is evenly distributed between the fibers to enhance structural integrity. This advanced and rational wall structure ensures optimal material performance. By meeting the necessary strength requirements, it enhances rigidity and guarantees product stability and reliability. Due to its excellent chemical resistance, light weight, high strength, no scaling, strong impact resistance, long service life, and lower overall cost compared to traditional steel pipes, as well as fast installation and high reliability, this type of pipe has gained widespread acceptance among users.
Performance characteristics of high-density polyethylene thermal insulation steel pipe include:
1. The use of rigid polyurethane with low thermal conductivity as an insulating material provides superior thermal insulation properties.
2. When transporting water at 130°C over a distance of 40 kilometers, the temperature drop remains minimal, around just 1°C.
3. It offers strong waterproofing and corrosion resistance, eliminating the need for additional pipe trenches. It can be directly buried in the ground or underwater, making construction simple, quick, and cost-effective.
4. It also exhibits excellent corrosion and impact resistance under low-temperature conditions, allowing direct burial in permafrost layers.
5. The outer casing is made of high-density polyethylene (HDPE), which is resistant to both biological and chemical corrosion.
6. High-density polyethylene thermal insulation steel pipes are available in various diameters ranging from DN20 to DN1200, with customizable insulation thicknesses and matching fittings such as elbows, tees, reducers, and fixed joints.
7. The product complies with industry standards for urban construction.
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 required standards, and the surface tension of the outer shell reaches 50 dynes/cm.
9. Made from high-density polyethylene with added antioxidants and other additives, the raw materials and finished products are strictly tested 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 is equipped with imported and domestic high-pressure foaming machines and hydraulic pipe threading machines, ensuring high-quality production and improved performance of the final product.
