Several special properties of PE pipe
1, PE pipe does not leak characteristics? Polyethylene pipe mainly uses fusion joints (hot melt connection or electrofusion connection), essentially ensuring the identity of the interface material, structure and pipe body itself, to achieve the integration of joints and pipes. Experiments have confirmed that the tensile strength and burst strength of the interface are higher than that of the pipe body. Compared with rubber joints or other mechanical joints, there is no joint leakage problem.
2, PE pipe high toughness characteristics? Polyethylene pipe is a high toughness pipe, its elongation at break generally exceeds 500%, the ability to adapt to uneven settlement of the pipe base is very strong. It is also a pipe with excellent seismic performance. In the 1995 Kobe earthquake in Japan, polyethylene gas pipes and water pipes were the only pipe systems that were spared. Therefore, after the earthquake in Japan, the use of PE pipes in the gas field was vigorously promoted.
3. The PE tube has excellent flexibility. The flexibility of the polyethylene allows the polyethylene tube to be coiled and supplied over a long length without the need for various connecting fittings. For non-excavation technology construction, the direction of the polyethylene pipe can be easily changed according to the requirements of the construction method, and the original size and size can be restored after the construction.
