Summary of HDPE Pressure Pipe Characteristics and Specifications

 This paragraph describes the characteristics and specifications of HDPE (high density polyethylene) pressure pipe. HDPE pipe is a type of pipe used to convey water, sewers, recycling systems, fire protection pipes and gas pipelines, and has a variety of excellent properties and applicability.



1. Dimensions and pressure ratings:

    - HDPE pressure pipe is available in sizes from 1 inch to 138 inches.

    - Available pressure levels include IPS (iron pipe size) and DIPS (plastic pipe size).

    - DR (Dimension Ratio) range from 7 to 32.5.


2. Standard specifications:

    - Compliant standards include ASTM D3035, ASTM F714, AWWA C906, NSF/ANSI 6, ASTM D3350, ISO 4427, GB/T 13663, EN12201, AS/NZS, DIN, GOST, etc.


3. Resin and color:

    - Made of PE4710 Cell Class PE445574C standard resin.

    - Standard stripe colors include blue (water), green (sewer), purple (recycling), red (fire main), yellow (gas), etc., used to distinguish pipes for different purposes.


4. Features and Benefits:

    - Hot melt, fully restrained, zero-leak joints.

    - Excellent chemical resistance, does not rust, rot, form tubes, corrode or support biological growth.

    - Smooth inner surface provides excellent flow characteristics.

    - Able to withstand surge pressures above operating pressure.

    - Unparalleled flexibility, toughness and durability for trenchless applications.

    - The pipe is lightweight and highly ductile, which improves the convenience of handling and installation.

    - Excellent fatigue resistance to frequent surge events.

    - Excellent impact resistance.

    - Long-term UV resistance, suitable for use on the ground.

    - Minimizes maintenance and life cycle costs due to zero leakage, fully restrained joints and excellent chemical resistance.

    - Tested for over 70 years for reliable long-term performance.


These properties make HDPE pressure pipe an ideal choice in many fields, including industry, municipal engineering, environmental engineering, and construction.
