MPP trenchless power pipe is also called MPP jacking pipe or dragging pipe. It has the characteristics of high temperature resistance and external pressure resistance. MPP power pipe uses modified polypropylene as the main raw material. It does not require a large amount of mud, excavation and road surface damage. It is a construction project for laying pipelines and cables in special areas such as roads, railways, buildings, and riverbeds. Compared with the traditional "trench digging and pipe burying method", trenchless power pipe projects are more in line with current environmental protection requirements. MPP power pipes are subdivided into many types, among which compression-resistant MPP power pipes are more widely used.
