HDPE PE100 pipe is a new type of plastic pipe made of high-density polyethylene raw materials. It is the highest grade product among polyethylene pipes. Its minimum required strength (MRS) reaches 10MPa. It has excellent physical properties and chemical stability and is widely used in municipal engineering, construction engineering, agricultural irrigation and other fields.
