Polyethylene is a widely used plastic material and is widely used in fields such as water supply, drainage, gas transmission, agricultural irrigation, and industrial fluid transmission due to its good chemical stability, corrosion resistance, low friction coefficient, and good flexibility. Plastic pipes are divided into different grades, such as PE-80 and PE-100, corresponding to different pressure-bearing capacities. Due to the characteristics of simple installation, long service life, and low maintenance cost of plastic pipes, they are widely used in modern pipeline projects.
