MPP power pipes, also known as MPP jacking pipes or pulling pipes, are divided into excavation and non-excavation types.

MPP power pipes are made primarily from modified polyolefin. They are ideal for laying pipelines without extensive excavation of mud, soil, or destruction of special locations such as roadways, buildings, and riverbeds. With their high-temperature resistance and ability to withstand external pressure, they are suitable for cable trays of high-voltage transmission lines over 10KV. They are available in standard and reinforced types. The standard type is suitable for excavation and non-excavation construction where the burial depth is less than 4 meters; the reinforced type is for non-excavation construction with burial depths greater than 4 meters.

The welding machine for MPP power cable protection pipes uses hot melt welding for butt joints, with the melting point around 200 degrees, not exceeding 220 degrees. Once the temperature is reached, the two ends can be joined together. Moreover, the MPP power pipes are orange-red, featuring high thermal deformation temperature and low-temperature impact resistance. They are also lightweight, smooth, have low frictional force, and can be joined using hot melt welding.
