An article to help you understand HDPE pressure pipes

This text is about the technical specifications and characteristics of HDPE (high density polyethylene) pressure pipe. HDPE pressure pipe is a piping system used to transport liquids and has many advantages and suitability features. Let me briefly explain this information:

Dimensions and DR Values (Dimensional Ratio):

HDPE pressure pipe dimensions are 1 inch diameter with a specific thickness of 0.138 inches. Pipes can be provided in different sizes and DR values (pressure levels) according to different needs, ranging from 7-32.5.

Standard specifications:

This pipe complies with multiple international standards, including ASTM D3035, ASTM F714, AWWA C906, ISO 4427, GB/T 13663, EN12201, AS/NZS, DIN, GOST, etc. These standards ensure the quality and performance of the pipes, which you can customize to your needs.


HDPE pressure pipe uses PE4710 resin, which is a PE445574C grade material. This resin has excellent performance characteristics and is suitable for different application scenarios.

Color Coding:

Different colors of pipes are used for different applications, such as blue for water pipes, green for sewer pipes, purple for recycling systems, red for fire mains, and yellow for gas pipes.

Features and Benefits:
1. Hot-melt joints: Use hot-melt joints to achieve fully constrained and zero-leakage pipe connections.
2. Chemical resistance: Not prone to rust, rot, corrosion or support biological growth.
3. Flow characteristics: The inner surface is smooth and has excellent fluid flow characteristics.
4. Pressure resistance: able to withstand surge pressure higher than the working pressure.
5. Flexibility and durability: With excellent flexibility, toughness and durability, it is suitable for trenchless applications.
6. Lightweight: The pipe is light and ductile, making it easy to carry and install.
7. Anti-fatigue ability: Excellent anti-fatigue ability against frequent surge events.
8. Impact resistance: Excellent impact resistance.
9. Anti-ultraviolet: Long-term anti-ultraviolet, suitable for use on the ground.
10. Low Maintenance Costs: Reduced maintenance and life cycle costs due to zero leakage, fully restrained joints and chemical resistance.
11. Long-term performance: With over 70 years of proven long-term performance.

These properties make HDPE pressure pipe an ideal pipe material in many projects and applications, especially where durability, chemical resistance and ease of installation are required.
