HDPE dr11 pipe, also known as HDPE sdr11 pipe, is a high-quality pipe material widely used in urban water supply networks, agricultural irrigation, petrochemicals, and other fields.
HDPE sdr11 pipe definition
HDPE SDR11 pipe is named because its size ratio SDR (Standard Dimension Ratio) value is 11, which means that the ratio of the outer diameter of the pipe to the wall thickness is 11. This specification of pipe is usually used to transport gaseous artificial gas, natural gas and liquefied petroleum gas due to its moderate wall thickness. Compared with PE pipes such as SDR17.6 used for low-pressure and courtyard pipelines, SDR11 has higher strength and pressure resistance and is suitable for use in medium-pressure gas pipelines.
Material properties
HDPE (High Density Polyethylene) is a highly crystalline, non-polar thermoplastic resin with excellent physical properties and chemical stability. Its original appearance is milky white, and it is translucent to a certain extent in a thin cross-section. HDPE materials have good tolerance to most domestic and industrial chemicals, but some highly corrosive chemicals, such as concentrated nitric acid, xylene, and carbon tetrachloride, may cause chemical corrosion.
Advantages of HDPE SDR11 pipe
1. Corrosion resistance: HDPE SDR11 pipe can resist corrosion from a variety of chemical media, and the chemicals present in the soil will not cause degradation to the pipe. Therefore, it is particularly suitable for conveying corrosive media or buried installation.
2. High strength and toughness: HDPE SDR11 pipe has high strength and toughness and can withstand greater external pressure and impact. This makes it have a wide range of application prospects in municipal water supply and drainage projects, agricultural irrigation, and other fields.
3. Lightweight material: HDPE material is lightweight and easy to carry and install, which greatly reduces the demand for manpower and equipment and reduces installation costs.
4. Wear resistance: Compared with steel pipes, HDPE SDR11 pipes have better wear resistance. Under harsh conditions such as mud transportation, HDPE pipes have a longer service life and a better economy.
5. Aging resistance: HDPE SDR11 pipes have good aging resistance and can be stored or used outdoors for up to 50 years without damage due to ultraviolet radiation.
6. Connection performance: HDPE SDR11 pipes are connected by electric hot melt, and the strength of the joint is higher than the strength of the pipe body. This connection method ensures the overall stability and reliability of the pipeline system.
Application fields
1. Municipal engineering: HDPE SDR11 pipe is widely used in municipal water supply and drainage projects, including tap water pipes, sewage pipes, rainwater pipes, etc. Its corrosion resistance, smooth inner wall, and easy installation make HDPE pipe an ideal substitute for traditional steel pipes and polyvinyl chloride drinking water pipes.
2. Agricultural irrigation: HDPE Irrigation Pipe is light, easy to install, and has a long service life. It is particularly suitable for water pipes and sprinkler pipes in agricultural irrigation systems. Its wear resistance and aging resistance ensure the stability and reliability of the pipe in long-term use.
3. Petrochemical: In the field of petrochemicals, HDPE SDR11 pipe is used to transport various corrosive media due to its excellent corrosion resistance.
HDPE dr11 pipe has become the preferred material for modern pipeline systems with its excellent corrosion resistance, high strength and rigidity, lightweight materials, good wear resistance and aging resistance, and reliable connection methods. With the advancement of science and technology and the improvement of environmental awareness, HDPE SDR11 pipe will be widely used in more fields, bringing more convenience and benefits to people’s lives and production.
