MPP power pipe is mainly made of modified polypropylene. It does not require extensive excavation of mud, soil or damage to the road surface. It is an engineering project for laying pipes, cables, etc. in special areas such as roads, railways, buildings and riverbeds. Compared with the traditional "trenching and pipe laying method", trenchless power pipeline engineering is more in line with the current environmental protection requirements. This technology eliminates the troublesome factors such as dust and traffic congestion brought by traditional engineering. It can also lay pipelines in areas where excavation work cannot be carried out, such as historical site protection areas, busy streets, crop and farmland protection areas, expressways, and rivers. It features high temperature resistance and external pressure resistance, and is suitable for the transmission pipe materials of high-voltage transmission lines above 10KV. The 110mm to 250mm range is divided into common type and reinforced type. The common type is suitable for excavation and laying projects as well as non-excavation and crossing projects with a burial depth of less than 4M. The reinforced type is suitable for non-excavation crossing projects with a burial depth greater than 4 meters. This product has passed the test of the National Chemical Building Materials Testing Center and achieved good social and economic benefits.
