MPP power pipe

MPP power pipe uses modified polypropylene as the main raw material, which is a construction project of laying pipes and cables in special sections such as roads, railways, buildings, and under the riverbed without massive dredging, digging and damage to the pavement. Compared with the traditional "trenching and pipe burying method", the trenchless power pipe project is more suitable for the current environmental protection requirements, and the dust flying, traffic congestion and other disturbing factors caused by the traditional construction can be removed. This technology can also be used to lay pipelines in some areas where the excavation operation cannot be carried out, such as historic sites protection areas, downtown areas, crop and farmland protection areas, highways, rivers, etc.
