What Is The Difference Between PE 80 And PE 100?
Jun 11, 2024| 1. What is the PE 80
PE 80 is a polyethylene grade that has medium density and is commonly used for gas and water pipelines. It has a minimum required strength of 8 MPa and a minimum required density of 0.93 g/cm³. PE 80 is less strong and more flexible than PE 100, but still has good chemical resistance and can be welded easily. It is often used in low-pressure applications where flexibility is important. PE 80 is also sometimes referred to as MDPE (medium density polyethylene).
2. What is the PE 100
PE 100 is a high-density polyethylene (HDPE) resin that has a minimum required strength of 10 megapascals (MPa) and a minimum required density of 0.95 grams per cubic centimeter (g/cm³). PE 100 is widely used in various industries, including water supply, gas distribution, and sewage systems, due to its high strength, excellent chemical resistance, and low weight. It is also known for its durability and resistance to temperature changes and abrasion.
3. What is the difference between PE 80 and PE 100
PE 80 and PE 100 are both polyethylene pipe grades and share some common characteristics, such as being relatively lightweight and durable. However, there are some key differences:
PE 100 has a higher density, with a minimum required density of 0.95 g/cm³ compared to PE 80, which has a minimum required density of 0.93 g/cm³. This makes PE 100 slightly stronger and more rigid than PE 80.
PE 100 has a higher minimum required strength of 10 MPa, while PE 80 has a minimum required strength of 8 MPa. This means that PE 100 is stronger and more resistant to pressure, making it suitable for high-pressure applications.
PE 80 is commonly used for low-pressure applications like water supply and irrigation systems, while PE 100 is used in high-pressure applications such as gas distribution and mining activities.
Both PE 80 and PE 100 are easy to weld, but PE 80 requires a lower welding temperature than PE 100.
In summary, while both grades are made from the same material and are similar in many ways, the higher density and strength of PE 100 make it better suited for high-pressure applications.
4. What is the price of PE 80 and PE 100
The prices of PE 80 and PE 100 can vary depending on several factors, such as the country of production, the supplier, and the quantity ordered. Generally, PE 100 is more expensive than PE 80 due to its higher density and strength.
