PE 80 is a common material grade for HDPE (high density polyethylene) pipes and is widely used in a variety of piping systems, especially where pressure and corrosion resistance are required. It represents one of the different grades of high-density polyethylene and has a certain difference in the market compared to other types of polyethylene pipes such as PE 100. Below, we will introduce the meaning and application of PE 80 in HDPE tube in detail.
PE 80 is a molecular structure grade of high-density polyethylene (HDPE), which is usually used in the production of various pressure piping systems. The "80" in PE 80 refers to the design pressure rating of the material, that is, the maximum long-term working pressure it can withstand is 8 MPa (megapascals), which is equivalent to a pressure of 80 bars.
Compared with PE 100, PE 80 has a slightly lower pressure bearing capacity, so its application range may be limited to a certain extent, but it is still a very economical and practical choice in many environments that do not require extremely high strength.
1. Strong corrosion resistance: PE 80 pipe has excellent chemical stability and can resist corrosion from a variety of acids, alkalis and salts. Its corrosion resistance makes it widely used in industries such as agricultural irrigation, sewage treatment, and oil and gas transportation.
2. Good pressure resistance: Although the pressure resistance of PE 80 pipes is lower than that of PE 100, its design pressure reaches 8 MPa, which can meet the requirements of most conventional pipeline projects, especially in low-pressure pipeline systems, PE 80 pipes can give full play to their advantages.
3. Toughness and impact resistance: PE 80 has good toughness and can maintain good impact resistance in cold climates, reducing losses caused by pipeline rupture.
4. Easy processing: PE 80 pipes have excellent processing performance and good weldability. They can be connected by hot melt, butt welding and other methods. They have strong adaptability and are easy to construct.
PE 80 pipes are used in many fields due to their excellent performance. Here are some typical application scenarios:
1. Drinking water transportation: The corrosion resistance and good physical properties of PE 80 pipes make it an ideal choice for water supply systems. Although PE100 pipes are more common in high-pressure pipelines, PE 80 can also meet the needs well in some low-pressure areas.
2. Natural gas transportation: PE 80 pipes are often used in urban natural gas pipelines. They have the ability to resist chemical corrosion and impact, and can effectively avoid pipeline damage caused by the external environment.
3. Agricultural irrigation: In agricultural irrigation, PE 80 pipes are often used in water pipelines due to their low cost and good weather resistance. It can resist the erosion of various chemical substances and ensure the smooth flow of water.
4. Sewage and wastewater pipelines: In the transportation of sewage and wastewater, PE 80 pipes have good corrosion resistance and pressure resistance, can adapt to various harsh environments, and reduce maintenance costs.
Although both PE 80 and PE 100 belong to HDPE pipes, their main differences lie in the design pressure and application areas:
1. Design pressure: The long-term use pressure of PE 100 pipes is usually 10 MPa, which is suitable for pipeline systems with higher pressures, while the design pressure of PE 80 pipes is 8 MPa, which is more suitable for pipeline systems with lower pressures.
2. Physical properties: PE 100 has higher strength, better pressure resistance and weather resistance than PE 80, and is suitable for more demanding environments, such as applications exposed to ultraviolet rays or extreme temperatures for a long time.
3. Cost difference: Due to the superior performance of PE 100, its cost is usually higher than PE 80. Therefore, in some cases where the budget is limited but reliable performance is still required, PE 80 is a cost-effective choice.
As an important grade of HDPE pipe, PE 80 is widely used in drinking water, natural gas transmission, agricultural irrigation and sewage treatment for its good corrosion resistance, pressure resistance and toughness. Although its design pressure is lower than PE 100, it still has quite strong performance and can meet the needs of most conventional piping systems. In addition, the cost of PE 80 is relatively low, so for some projects with tight budgets, PE 80 pipe is undoubtedly an ideal choice.
