What does PE100 grade HDPE pipe mean?
PE100 grade HDPE pipe refers to pipes made of PE100 grade in high-density polyethylene (HDPE) material.
What is PE100?
PE (Polyethylene) Grading: HDPE materials are divided into different grades according to density, mechanical properties and pressure resistance, and the common ones are PE32, PE63, PE80 and PE100.
PE100 is the highest performance grade at present, with higher compressive strength, crack propagation resistance and long-term durability.
The number (such as 100) represents the minimum required strength (MRS) in MPa. The MRS of PE100 is 10 MPa, which is an upgraded version of PE80 (8 MPa).
Characteristics of PE100 grade HDPE pipe
High strength: can withstand higher pressure (common pressure grades: PN10, PN16, etc.), suitable for high-pressure scenarios such as water and gas transmission.
Chemical corrosion resistance: Resistant to acids, alkalis, salts and other chemicals, suitable for industrial wastewater systems.
Lightweight and flexible: Lightweight (only 1/8 of metal pipes), easy to transport and install, and can be bent to adapt to the terrain.
Long life: Design life can reach more than 50 years, UV resistance (if carbon black is added) and environmental stress cracking resistance.
Environmentally friendly and non-toxic: Meets drinking water standards (such as ISO 4427) and is often used in water supply networks.
Common application areas
Water supply system: municipal tap water, direct drinking water pipeline.
Gas transmission: medium and low pressure gas pipeline network (must comply with standards such as ISO 4437).
Industrial pipeline: chemical fluid, slurry transportation.
Drainage/sewage system: strong corrosion resistance, suitable for rainwater and sewage discharge.

International Standard Reference
ISO 4427: Production and testing standard for PE100 water supply pipes.
EN 12201: European standard for HDPE pipes for water supply.
GB/T 13663: National standard for PE pipes for water supply in China.
PE100 grade HDPE pipes have become the preferred material for modern pipeline engineering due to their high strength, corrosion resistance and long life, especially suitable for high-pressure and high-demand application scenarios. When choosing, pay attention to the certification standards (such as ISO or GB) and the actual working conditions.
