PE4710 HDPE pipe (Polyethylene 4710), as an advanced plastic pipe, is widely used in water conservancy, natural gas transmission, oil pipelines, sewage pipelines and other infrastructure construction. It is made of high-density polyethylene (HDPE) material and has excellent corrosion resistance, wear resistance, pressure resistance and long service life. The name of PE4710 pipe comes from the standard number and characteristics of its material. “PE” stands for polyethylene, and “4710” indicates the specific level of performance of the material, especially the parameters related to compressive resistance and long-term load bearing capacity.
Overview of High-density Polyethylene (HDPE)
Polyethylene (abbreviated as PE) is a common thermoplastic with good chemical stability, high tensile strength and good processability. According to different densities, polyethylene can be divided into low-density polyethylene (LDPE), medium-density polyethylene (MDPE) and high-density polyethylene (HDPE). HDPE has strong mechanical strength, corrosion resistance and oxidation resistance due to its compact molecular structure and high density.
PE4710 is a special grade of high density polyethylene, a high quality polyethylene material that meets international standards. Compared with other types of PE materials, PE4710 has higher environmental stress cracking resistance (ESCR) and longer service life.
PE4710 HDPE Pipe Specifications
Outer Diameter (OD): PE4710 pipes usually have a wide range of outer diameters, generally ranging from 20mm to 2000mm or more. The specific size depends on the use requirements.
Wall Thickness (WT): Wall thickness and outer diameter together determine the pressure rating of the pipe. Common wall thicknesses have the following common standards:
SDR11 (relatively small wall thickness, suitable for higher pressure occasions)
SDR17 (moderate, suitable for general pressure requirements)
SDR26 (relatively thick, suitable for low pressure applications)
Pressure level: PE4710 material has high pressure resistance, common pressure levels are:
PN6 (for 6 bar pressure)
PN8 (for 8 bar pressure)
PN10 (for 10 bar pressure)
PN16 (for 16 bar pressure)
PN20 (for 20 bar pressure)

Features of PE4710 HDPE pipe
1. Excellent corrosion resistance
PE4710 pipe has strong corrosion resistance and can resist the erosion of various chemicals, including acids, alkalis, salts and many organic solvents. This feature makes it widely used in industries such as oil, natural gas and sewage treatment.
2. Long service life
The design life of PE4710 pipe can usually reach more than 50 years. Its resistance to environmental stress cracking, UV resistance and aging resistance enable it to maintain stable performance in various harsh environments. This is its important advantage in urban infrastructure construction, long-distance water pipelines and other fields.
3. High pressure resistance and wear resistance
Because PE4710 pipe has a high density and a strong molecular structure, it can withstand greater pressure and has strong wear resistance. Even in the long-term use process, the pipe will not be blocked or broken due to wear.
4. Good toughness and impact resistance
PE4710 pipe has good toughness and can resist external impact and pressure. In low temperature environments, the pipe will not break due to embrittlement, ensuring the reliability of the pipeline under extreme climatic conditions.
5. High and low temperature adaptability
High-density polyethylene pipes maintain their physical properties under a wide temperature range. Generally speaking, the operating temperature of PE4710 pipes can be between -40℃ and 60℃, adapting to cold and hot environments, and suitable for engineering projects in different geographical areas.
6. Non-toxic and environmentally friendly
PE4710 pipes do not release harmful substances during use, so they are widely used in drinking water transportation, food industry, and environmental protection. It is an environmentally friendly material that meets the needs of modern sustainable development.
Application fields of PE4710 pipes
1. Urban water supply pipelines
PE4710 pipes have become ideal materials for urban water supply pipeline construction due to their excellent corrosion resistance and long service life. Especially in the case of complex water quality such as groundwater transportation and seawater transportation, PE4710 pipes can effectively avoid water pollution and pipeline corrosion.
2. Natural gas and oil transportation
The high pressure resistance and corrosion resistance of PE4710 pipes make it play an important role in the transportation of natural gas and oil. Compared with traditional metal pipes, PE4710 pipes are more corrosion-resistant and high-pressure-resistant, and the construction process is more convenient.
3. Sewage discharge and sewage treatment
Because PE4710 pipes have extremely high chemical corrosion resistance, they are widely used in sewage discharge and sewage treatment. Especially when treating sewage containing acidic, alkaline or corrosive substances, PE4710 pipes show excellent performance.
4. Agricultural irrigation system
PE4710 pipes also play an important role in agricultural irrigation. It can not only effectively prevent pipelines from rusting or corrosion, but also resist high temperature and frost damage, ensuring the stability and long-term operation of the irrigation system.
5. Power and communication cable protection pipes
PE4710 pipes can also be used as protection pipes for power and communication cables to protect the cables from the external environment and extend the service life of the cables. Especially when laying cables underground, PE4710 pipes can provide additional physical protection.
Installation and Maintenance
Installation Method
PE4710 pipe is usually installed by hot-melt or electric-melt connection. Hot-melt connection heats the connecting parts of the pipe to melt and form a permanent joint, while electric-melt connection uses electric heat to heat HDPE Electrofusion Fittings. Both connection methods can ensure the reliability and tightness of the pipe connection.
Maintenance and Inspection
PE4710 pipe requires almost no excessive maintenance during use. Regular inspection of the integrity of the pipe and whether there are leaks at the joints is the key to maintenance. Due to its material properties, PE4710 pipe is almost not affected by biological deposition, so it is not easy to get blocked.
As a new type of engineering pipeline material, PE4710 HDPE pipe has become an important choice in many industries with its excellent physical and chemical properties. Whether in water conservancy projects, oil and gas transportation, or sewage treatment, PE4710 pipe has shown its unique advantages. With the continuous advancement of technology, the application field of PE4710 pipe will be further expanded and become one of the indispensable materials in future infrastructure construction.
