Advantages of HDPE double-wall corrugated pipe over traditional cement pipe

Before HDPE double-wall corrugated pipe is widely used, municipal drainage projects mostly rely on cement pipes. However, in recent years, with the continuous progress of HDPE double-wall corrugated pipe technology, its application scope is rapidly expanding, and it gradually replaces the traditional cement drainage pipe.

So, why can HDPE double-wall corrugated pipe get such a wide range of applications? Compared with the traditional cement pipe, what unique advantages does it have?

1. **Excellent Flexibility***

   Drainage pipes buried underground need to withstand pressure from the ground. Traditional cement pipes are prone to rupture under heavy pressure, leading to high maintenance costs. HDPE double-wall corrugated pipe has excellent flexibility, which can effectively disperse the pressure without changing its shape, avoiding pipe rupture and significantly reducing maintenance costs.

2. **Extremely long service life**

   The service life of cement drainage pipe is usually about 25 years, while HDPE double-wall corrugated pipe adopts advanced high-density polyethylene material, which has strong corrosion resistance, and can maintain stable characteristics in all kinds of complex underground environments, and its service life can be up to more than 50 years.

3. **Excellent sealing **

   HDPE double-wall corrugated pipe, as a plastic product, has good waterproof performance itself and will not leak. In addition, the pipe has a long single length, a relatively small number of interfaces, and a simple and reliable connection, which further ensures the sealing of the system.

4. **Low water flow resistance**

   Due to the smooth inner wall of HDPE double-wall corrugated pipe, the hydraulic friction coefficient is small, under the same caliber condition, its flow rate is about 30% higher than that of cement pipe, the water flow is smoother and the conveying efficiency is higher.

5. **Convenient transportation and construction

   HDPE double-wall corrugated pipe is light in weight and flexible, which is easy to be transported and handled without the aid of large-scale professional equipment. In the construction process, the installation speed is fast, and the laying of 40 meters of pipeline can be completed within 8 hours, and only three to four workers can meet the construction needs. In contrast, the cement pipe is more bulky, not only transportation is inconvenient, and must be installed with the help of mechanical equipment, consuming a lot of manpower and material resources, increasing the construction cost.

In summary, although the initial purchase cost of HDPE double-wall corrugated pipe is slightly higher than that of cement pipe, from the point of view of overall cost and service life, choosing HDPE double-wall corrugated pipe is undoubtedly a more economical choice.
