1. The inner wall of PE agricultural irrigation pipe is smooth, with small fluid resistance and no rust. It does not require strict water quality and does not accumulate scale.

　　2. PE agricultural irrigation pipe has good low temperature resistance and can be used normally in a wide temperature range of -20℃ to 40℃.

　　3. Good wear resistance. When used as a movable branch pipe, dragging on the ground will not affect the service life of the pipe material.

　　4. Adding special additives to prevent damage to buried pipes by rodents and other gnawing animals.

　　5. The pipe has stable performance, good sanitary performance, does not affect water quality, and does not affect the non-toxic and pollution-free of crops.

　　6. PE agricultural irrigation pipe has excellent aging resistance, and its performance can be guaranteed under long-term exposure to sunlight or burial.

　　7. Materials processed into PE agricultural irrigation pipes dissolve multiple nutrients during the water conveyance process, making the water nutritious, increasing nutrient accumulation in crops during photosynthesis, and providing sufficient nutrients.

　　8. The addition of mineral elements mineralizes the water, such as manganese as an activator, which can promote starch decomposition, seed germination, growth, and increase the organic and mineral content of crops.

　　9. The addition of antibacterial agents to the pipe can inhibit Escherichia coli at 1000/L, ensuring the safety of agricultural product consumption.

　　10. PE pipes have good toughness, can be bent, coiled, and conveniently stored.

　　11. PE agricultural pipes have excellent resistance to rapid crack propagation and slow crack growth, as well as good resistance to hanging.

　　12. PE agricultural irrigation pipe has good corrosion resistance and stable performance. When transporting water with injected fertilizers, it will not be corroded and will not destroy the nutrients in the fertilizer, ensuring the production needs of crops.

　　13. Particularly resistant to chemical substances, especially resistant to seawater intrusion, suitable for coastal marshy areas, strong adaptability to soft ground, suitable for seawater aquaculture, irrigation waterways, farmland consolidation, etc. The use of polyethylene pipelines greatly saves labor and equipment materials for installation, reduces operation and maintenance costs, and extends service life, thus having lower comprehensive engineering costs.
