It has many advantages, including excellent electrical insulation, high heat deformation temperature and low temperature impact performance, higher tensile and compressive resistance than HDPE, light and smooth, low friction resistance, can be hot-melt welded, and the long-term use temperature range is -5 to 70°C. In addition, MPP pipe does not require a large amount of dredging, digging and road surface damage. It can be widely used in pipeline projects such as laying pipelines and cables in special areas such as roads, railways, buildings, and riverbeds. It can be widely used in municipal, telecommunications, electricity, gas, tap water, heat and other pipeline projects.

[0003] Most existing MPP pipes are connected by hot-melt connection. However, the operation process of hot-melt connection is relatively complicated and requires multiple steps such as pretreatment, heating, and docking of the pipes, which results in a slow and inconvenient connection speed of the MPP pipe combination.
