The characteristics and applications of HDPE pipes can be summarized as follows: 1. HDPE pipe stands for High-Density Polyethylene pipe; 2. Its main application areas include urban water supply systems, gas transmission pipelines, drainage facilities, and agricultural irrigation projects; 3. This material has corrosion resistance and can effectively resist chemical corrosion; 4. It has excellent anti-aging properties, which can significantly extend its service life; 5. The smooth inner wall structure can prevent dirt deposition; 6. The design that reduces water flow resistance helps to improve fluid transportation efficiency.
