With stable product quality and advanced manufacturing processes, we provide safe, durable and efficient pipeline solutions for various infrastructure construction projects.
MPP power conduit, also known as modified polypropylene power cable protection pipe, uses modified polypropylene as its main raw material. It allows for the laying of pipelines and cables in special locations such as roads, railways, buildings, and riverbeds without extensive dredging or road surface damage. Compared to the traditional “trenching and burying method,” trenchless power conduit engineering is more environmentally friendly, eliminating the dust, traffic congestion, and other disturbances caused by traditional construction. This technology can also be used to lay pipelines in areas where excavation is not feasible, such as historical sites, urban areas, crop and farmland protection areas, highways, and rivers. Its high temperature resistance and external pressure resistance make it suitable for high-voltage power transmission cables of 10KV and above. Available in sizes from 110mm to 250mm, it is divided into standard and reinforced types.
The standard type is suitable for trenching and trenchless crossing projects with a burial depth of less than 4 meters; the reinforced type is suitable for trenchless crossing projects with a burial depth greater than 4 meters. This product has passed the testing of the National Chemical Building Materials Testing Center and has achieved good social and economic benefits.

● Before connecting pipes, mill the connecting ends, clean, heat the pipe openings, and ensure both ends of the pipe are flat and pressure-welded securely to form a uniform convex joint.
● When horizontally directional drilling is used to lay power cable pipes, the drilling trajectory, reference points, and control elevation of the construction area must be monitored at all times. Construction must be stopped immediately if any problems are found.
● Before connecting pipes, check their appearance, dimensions, and manufacturer. If pipes from different manufacturers need to be mixed, they must be inspected and confirmed to be of equivalent quality before use.
● After each connection is completed, an inspection should be conducted. Any connections that do not meet requirements must be reworked.
● Pipes should be stacked neatly, kept away from high temperatures, and handled with care during transport; they must not be thrown or dropped.
● During construction, the project should undergo phased acceptance according to its implementation details, culminating in a final acceptance inspection upon completion. The acceptance sequence should be: acceptance by the construction team, acceptance by the construction unit’s quality inspection department, and then submission to the supervision unit and the construction unit for final acceptance.
● The drilling process of the pilot hole should be supervised on-site, and the drilling trajectory should be confirmed and certified.
● The pipe welding and assembly process should be supervised on-site, and the pipe welding and assembly should be inspected and certified.
● After pipe laying, the construction unit should, together with the supervision unit, inspect and certified the numbering of the pipelines at both ends and the pipe flow test.
● The construction of the manholes at both ends of the pipeline and the connecting pipework should be inspected according to relevant regulations.
● Test reports for the pipes and their joints should be included in the project completion materials and ultimately submitted to the construction unit for acceptance. The construction unit will organize the final acceptance inspection upon project completion.
