HDPE double-wall corrugated pipe originated in Germany. It was widely used in China due to the many problems that occurred in the use of traditional cement drainage pipes in the country. The traditional cement drainage pipe in China was gradually replaced by HDPE double-wall corrugated pipe after many problems occurred in its use. The application of HDPE double-wall corrugated pipe means the development of the country in the road engineering industry because it has many advantages compared with the traditional cement pipe. You can see the actual advantages.
1. HDPE double wall corrugated pipe is not easy to crack under strong working pressure
First of all, let's compare the main parameters. HDPE double wall corrugated pipe is a kind of plastic pipe with very good tensile strength, 20 times of seamless steel pipe and 6.5 times of pvc pipe, which means that HDPE double wall corrugated pipe is not easy to be deformed and cracked when the road will move down or when earthquake disaster happens. It is not the traditional cement drainage pipe, and the advantage is higher than PVC pipe.
2. HDPE double-wall corrugated pipe has lower occupancy rate
The occupancy rate of HDPE double-wall corrugated pipe is 0.005. 0.018 for cement pipe. the advantage of this is that it is not easy to cause environmental pollution to the underground natural environment in the case of industrial wastewater, while the installation of cement pipe is easy to cause the problem of poor connection, and this infiltration problem will be more serious.
3. HDPE double-wall corrugated pipe long service life
Traditional cement drainage pipe after everyone's certification, 20 years can not be used. HDPE double-wall corrugated pipe has passed the certification. Can be used for more than 50 years, or even more than 70 years. The economic benefit of traditional cement drainage pipe is incomparable to HDPE double wall corrugated pipe.
The glossiness of HDPE double-wall corrugated pipe is far better than that of traditional cement pipe. It also has other advantages, such as not easy to accumulate, light quality, easy to install, even when encountering strong acid and alkali or under the road, it is not easy to cause cracking and tearing, so most of the sewage current stage pipes are HDPE double wall corrugated pipe.
