PE100 is a grade of High-Density Polyethylene (HDPE) pipe material characterized by its superior strength. Specifically, PE100 signifies Polyethylene with a Minimum Required Strength (MRS) of 10.0 MPa (megapascals), or 100 at 50 years and 20°C according to ISO 4427 standards. This means it is designed to withstand a stress of 10 MPa for at least 50 years at a temperature of 20°C.
In simpler terms, PE100 is a high-performance plastic used primarily for pressure pipes, prized for its durability, longevity, and resistance to cracking.
Here's a breakdown of its key features:
- Material: High-Density Polyethylene (HDPE)
- MRS (Minimum Required Strength): 10.0 MPa (100 at 50 years and 20°C according to ISO 4427)
- Application: Primarily pressure pipes for water and gas distribution.
- Advantages: High strength, long lifespan, chemical resistance, and excellent resistance to slow crack growth.
Compared to other PE grades like PE80, PE100 offers:
- Higher pressure rating: Allowing for the transport of fluids at higher pressures with the same pipe wall thickness.
- Thinner pipe walls: For the same pressure rating as PE80, PE100 pipes can have thinner walls, resulting in material savings.
- Enhanced durability: Better resistance to slow crack growth and long-term degradation.
Therefore, PE100 is a superior choice for demanding piping applications where reliability and longevity are crucial.
