[0002] PE pipe, or polyethylene pipe, is a polymer pipe made from polyethylene (PE) and is widely used in a variety of industries, including water supply, drainage, gas, chemical industry, power, and telecommunications. PE pipe is highly resistant to most chemicals and will not rust, making it suitable for transporting materials in a variety of corrosive environments. PE pipe also maintains excellent toughness at low temperatures, unlike metal pipes that become brittle.
[0003] When using PE pipes, depending on the installation environment and the needs of their function, they are sometimes installed in a pre-buried manner. The pipe trench is excavated according to the design drawings, the debris in the trench is cleaned, the foundation is leveled, the PE pipe is placed in the trench, the pipe docking is completed, and some sealing tests are performed before the soil is backfilled. During the soil backfill process, the soil may contain some hard materials such as stones, which may damage the PE pipe during the backfill process.
