HDPE DR11 Pipe, which is a pipe with a Standard Dimension Ratio of 11, is a pipe with superior performance and wide application. The following is a detailed introduction to HDPE DR11 Pipe:
High-density polyethylene (HDPE): HDPE is a highly crystalline, non-polar thermoplastic resin with excellent resistance to most household and industrial chemicals. At the same time, HDPE is non-hygroscopic, has good water vapor resistance, and has excellent electrical properties, especially high dielectric strength of insulation, making it suitable for a variety of application scenarios.
Standard Dimension Ratio (SDR): SDR is the ratio of the nominal outer diameter of the pipe to the wall thickness. The SDR value of HDPE DR11 Pipe is 11, which means that its wall thickness is 1/11 of the outer diameter. This design allows the pipe to have a lighter weight and better flexibility while maintaining a high pressure bearing capacity.
1. Strong pressure bearing capacity: Despite the high SDR value, HDPE DR11 Pipe still has a high pressure bearing capacity and can meet the needs of various pressure levels.
2. Chemical corrosion resistance: HDPE pipes can resist corrosion from a variety of chemical media, and the chemicals present in the soil will not cause any degradation to the pipes.
3. Good low-temperature impact resistance: The low-temperature brittle temperature of polyethylene is extremely low. HDPE DR11 Pipe can be safely used in the temperature range of -60℃ to 60℃, and the pipe will not be brittle during winter construction.
4. Good wear resistance: Compared with steel pipes, HDPE DR11 Pipe has better wear resistance, which means that HDPE pipes have a longer service life and better economy.
5. Good flexibility: The flexibility of HDPE DR11 Pipe makes it easy to bend. In engineering, obstacles can be bypassed by changing the direction of the pipeline, reducing the amount of pipe fittings and reducing installation costs.
6. Low water flow resistance: HDPE pipe has a smooth inner surface and its Manning coefficient is 0.009. The smooth performance and non-adhesive characteristics ensure that HDPE pipe has a higher conveying capacity than traditional pipes, while also reducing the pressure loss and water delivery energy consumption of the pipeline.
1. Municipal engineering: HDPE DR11 Pipe is often used as a pipe material for water supply and drainage systems, ensuring the effective delivery and discharge of water resources.
2. Agricultural irrigation: Its lightness, corrosion resistance and easy installation make it the preferred material for irrigation systems, effectively improving irrigation efficiency and water resource utilization.
3. Industrial production: In the chemical, petroleum, natural gas and other industries, HDPE DR11 Pipe is widely used in fluid delivery systems and is favored for its chemical corrosion resistance and high strength.
Connection method: HDPE DR11 Pipe usually adopts two methods: electric hot melt connection and hot melt butt welding. Electric hot melt connection is suitable for pipes with smaller diameters, while hot melt butt welding is suitable for pipes with larger diameters. Both connection methods can ensure that the strength of the pipe joint is higher than the strength of the pipe body.
Maintenance cost: Due to the excellent corrosion resistance and wear resistance of HDPE DR11 Pipe, its maintenance cost is relatively low. At the same time, its light weight and easy installation characteristics also reduce the installation cost.
HDPE DR11 Pipe is a recyclable and reusable material that meets the requirements of modern engineering for sustainable development. During the production and use process, HDPE DR11 Pipe does not produce harmful substances and is environmentally friendly.
In summary, HDPE DR11 Pipe plays an increasingly important role in modern engineering with its superior performance, wide application fields, and environmental sustainability.
