Standard specifications: dn20mm~2000mm.
Standard length: usually 5m, but flexible lengths such as 6m, 9m, etc. can be provided according to customer needs.
SDR 9 HDPE pipe production process
SDR 9 HDPE pipe is made of high-density polyethylene as the main raw material through advanced extrusion technology. This material has excellent corrosion resistance and can resist the erosion of various chemical media, ensuring that the pipeline will not be damaged by corrosion during long-term use. At the same time, HDPE material also has good impact resistance and cracking resistance, can withstand large external pressure and impact force, and ensure the stability and safety of the pipeline system.
Product Features
1. Corrosion resistance: SDR 9 HDPE pipe has strong corrosion resistance and can withstand the erosion of various chemical media. It has no electrochemical corrosion and does not require an anti-corrosion layer.
2. High strength: SDR9 HDPE pipe has high flexibility and good impact and earthquake resistance. Its elongation at break exceeds 350%, and it has a strong adaptability to uneven foundation settlement and dislocation.
3. Reliable connection: It adopts hot-melt butt, hot-melt socket, flange connection or electric hot-melt connection. The connection is convenient and reliable, and the strength of the joint is higher than the strength of the pipeline body.
4. Easy construction: SDR9 HDPE pipe is light and easy to carry, and can be constructed using a variety of new non-excavation technologies such as pipe jacking and directional drilling, which greatly reduces the difficulty and cost of construction.
5. Long service life: The service life can reach 50 years, greatly reducing the cost of maintenance and replacement.
Application Advantages
1. The application field of SDR 9 HDPE pipe is very wide. In the urban water supply system, SDR 9 HDPE pipe has become an ideal HDPE Water Supply Pipe with its excellent corrosion resistance and hygienic performance. Its inner wall is smooth and not easy to scale, which effectively avoids the problem of secondary pollution of water quality and ensures the safety of drinking water for residents.
2. In the drainage system, the pipe can effectively transport and treat various wastewater and sewage with its good chemical resistance and wear resistance, avoiding pipeline corrosion and blockage problems. At the same time, it has good flexibility and can adapt to geological activities such as foundation settlement and earthquakes to ensure the stability and safety of the drainage system.
3. SDR 9 HDPE pipe also plays an important role in agricultural irrigation, construction, mining, environmental protection and other fields. In the agricultural irrigation system, with its corrosion resistance, UV resistance and anti-aging characteristics, it ensures the long-term use of the pipe in the outdoor environment.
4. In construction and mining projects, it is used as a pipeline for transporting various fluids and gases to meet engineering needs.
5. In environmental protection projects, it is used in wastewater treatment, landfill leachate collection and other systems. Its environmental protection characteristics meet the requirements of green development and help protect the safety of the environment and water resources.
In summary, SDR 9 HDPE pipe has been widely used in various fields with its many advantages and has become the preferred material in modern pipeline systems.
