MPP Eelectric Pipe (modified polypropylene power pipe) is a new type of protective pipe developed for power cable laying scenarios. It is made of high-performance modified polypropylene (MPP) as the core material and is integrated into a single piece through specialized extrusion equipment. With excellent physical and mechanical properties and construction adaptability, it has become the preferred product for non excavation engineering and long-distance power pipeline construction, and is an upgraded solution to replace traditional power protection pipes.

The product adopts a modified polypropylene single substrate structure, with uniform wall thickness and dense structure of the pipe body. The core design focuses on the dual goals of "engineering adaptation+safety protection": on the one hand, the rigidity and toughness of the pipe body are improved through raw material modification technology, and the tensile, rolling, and deformation resistance are strengthened to meet the laying needs under complex geological conditions.

Its core advantages are reflected in "efficient construction+reliable protection": it is suitable for non excavation pipe jacking and pipe pulling construction processes, does not require large-scale excavation of the road surface, greatly shortens the construction period, and reduces construction costs; Wide temperature resistance range (-20 ℃~110 ℃), capable of withstanding high temperatures during cable operation and extreme outdoor weather conditions; It is anti-aging, anti-corrosion, and resistant to geological settlement, and it is not easy to be damaged when buried; The connection method is mainly based on hot melt docking, with joint strength consistent with the pipe body, tightly sealed and leak proof.

• Strong connection, good sealing and anti-leakage effect

  Hot melt butt joints or socket rubber ring connections can be used. The interfaces are resistant to pulling out, settling, and are waterproof and anti-seepage;

  Complies with EN 12814, DIN 16928

• Wide temperature range and weather resistance, suitable for both north and south regions

  ‑30℃～90℃ stable use, resistant to freeze-thaw and temperature difference, suitable for both cold and high-temperature areas;

  Comply with ASTM F714, GB/T 18252

• Light weight, efficient construction and low cost

  The pipe material is easy to cut and can be directly buried, piped, or laid without excavation, which greatly shortens the construction period;

  Comply with GB 50268, ISO 10460

• Long service life and low comprehensive operation and maintenance costs

  The service life of buried working conditions is ≥50 years, and it requires no anti-corrosion maintenance. It is widely used in municipal power grids, high-speed rail, photovoltaic, and urban renewal power pipeline networks;

  Comply with GB 50235, AWWA C906
