Compared to traditional piping materials, HDPE potable water pipeline systems feature a range of characteristics:

1. The polyethylene pipe systems are connected using electric heat fusion.

2. Polyethylene has a low-temperature brittleness temperature that is low, making it usable within a temperature range of -60 to 60°C. During winter construction, it is less prone to pipe cracking.

3. HDPE pipes are resistant to corrosion from a variety of chemicals, and the chemical substances present in the soil do not cause degradation to the pipes. Therefore, they are not prone to rotting, rusting, or electrochemical corrosion; in addition, they also do not promote the growth of algae, bacteria, or fungi.

4. Excellent Flexibility: The flexibility of HDPE pipes allows them to bend easily, which can be advantageous in engineering by routing the pipeline around obstacles. In many cases, the flexibility of the pipes can reduce the need for fittings and lower installation costs.

5. Low Flow Resistance: HDPE pipes feature a smooth inner surface with a Manning coefficient of 0.009. The smoothness and non-adhesive properties ensure that HDPE pipes have higher conveying capacity than traditional pipes, while also reducing pressure loss in the pipeline and water transportation energy consumption.

6. Easy to Handle: HDPE pipes are lighter than concrete pipes, galvanized pipes, and steel pipes, making them easy to transport and install. This requires less labor and equipment, thereby reducing the installation costs of the project.

7. Various Construction Methods: HDPE pipes offer a range of construction techniques, including conventional excavation, as well as non-excavation methods such as jacking, directional drilling, lining, and pipe bursting. This is an excellent choice for locations where excavation is not permitted.
