| Parameter name | Unit | Typical values/standard requirements | Explanation |
| Raw materials | - | PE80orPE100 | High-density polyethylene, PE100, has higher long-term hydrostatic strength and crack growth resistance |
| Density | g/cm | ≥0.941 | Reflect the purity and crystallinity of the material |
| Melt flow rate (MFR) | g/10min | ≤0.4 (190°C, 5kg) | The lower the value, the higher the molecular weight, and the better the resistance to environmental stress cracking |
| Tensile strength | MPa | ≥20 | The ability of pipe materials to resist tensile damage |
| Elongation at break | % | ≥350 | It reflects the flexibility and ductility of the pipe material. The higher the value, the better the toughness |
| Thermal stability (oxidation induction time OIT) | min | ≥20 (200°C) | The ability of materials to resist thermal and oxidative aging is related to their long-term service life |
| Resistant to environmental stress cracking | hr | ≥1000 (F₀Conditions) | The ability to resist cracking under the combined action of medium and stress is a key indicator |
The HDPE Power Pipe boasts exceptional strength and ring stiffness, ensuring it withstands soil pressure, heavy loads, and external impacts without deformation. Its inherent flexibility allows it to bend smoothly around obstacles, reducing the need for extra fittings and minimizing installation complexity. This dual benefit of strength and flexibility makes it ideal for both straight runs and complex routing in urban or rugged terrains.
Equipped with excellent corrosion resistance and chemical resistance, the pipe remains unaffected by soil chemicals, moisture, and harsh environmental conditions. It also offers reliable insulation, protecting power cables from short circuits and external interference. Unlike metal or concrete alternatives, it won’t rust, degrade, or crack over time, maintaining performance even in challenging settings.
Convenient construction is a key advantage—its lightweight design simplifies transportation, handling, and on-site installation, cutting labor costs and project timelines. With a long service life and maintenance-free operation, it delivers lasting value, eliminating the need for frequent repairs or replacements. Additionally, its environmental friendliness aligns with sustainable construction practices, reducing carbon footprint.
Ideal for urban power grid construction and renovation, the pipe is widely used for cable laying under city roads, residential communities, and commercial areas. It ensures safe, unobtrusive cable placement in densely populated zones, supporting reliable power supply for homes and businesses.
It plays a vital role in transportation infrastructure, including expressways, railways, airports, and ports. For large-scale engineering projects like power plants, substations, petrochemical bases, and mines, the pipe provides robust cable protection in high-demand industrial environments.
In the new energy field, it’s employed in solar photovoltaic power stations, wind farms, and charging pile networks, safeguarding cables that power renewable energy systems. It also supports communication and signal transmission, housing optical fibers and communication cables for seamless data transfer.
