Large diameter MPP power pipe, stable material selection for new construction of municipal power grid

The large-diameter MPP power pipe is a power cable protection pipe made of modified polypropylene as the main raw material. It is mainly developed for the use of buried high-voltage cables in municipal power grid construction projects. The conventional nominal diameter range covers 110mm to 315mm, which can meet the requirements of multiple sets of large-diameter power cables for simultaneous threading. The production of products follows the relevant general standards for power engineering pipes.

In terms of core selling points, the first is weather resistance and stable adaptation to complex working conditions: it can withstand the conventional use environment temperature from -5 ° C to 70 ° C, has excellent impact resistance and settlement resistance, and can withstand surface load, soil acid and alkali corrosion and a small amount of underground seepage erosion after buried laying. No additional anti-corrosion treatment is required, and the service life can reach more than 50 years. The second is strong insulation anti-penetration protection: the insulation grade of the pipe body meets the relevant safety requirements of the power industry, which can effectively block the infiltration of external water vapor and soil impurities, avoid hidden dangers such as leakage and short circuit of the cable due to external environmental interference, and reduce the impact of external open flames and external force damage on the cable. The third is that the construction is convenient and the comprehensive cost is controllable: the quality of the pipe is about 1/8 of that of the steel pipe of the same specification. There is no need for large lifting equipment for transportation, handling and installation. The pipe connection can be completed by hot melt docking. The seam has strong sealing performance. The construction period is about 30% shorter than that of traditional pipes, and the operation and maintenance cost is lower in the later stage. Fourth, the ring stiffness meets the standard load bearing capacity: the ring stiffness of the large diameter specification product can reach SN8 and above, which can meet the load requirements of the direct laying of sidewalks, non-motor vehicle lanes and motor vehicle lanes. There is no need to pour additional concrete protective layer, and it is suitable for a variety of buried depth construction requirements.

Applicable scenarios mainly include municipal power grid construction and renovation projects in urban core areas, power supporting pipeline projects in industrial parks, power pipeline laying projects in urban underpass tunnels, and power pipeline projects for urban rail transit. Suitable groups are municipal engineering construction units, power grid construction units, power engineering design units, and general contracting units for pipeline projects.

The production process of this product strictly follows the relevant national general standards and industry norms for plastic pipes used in power engineering. Before leaving the factory, the core indicators such as ring stiffness, impact strength and insulation performance are completed in batches, which meets the relevant compliance requirements of municipal power grid engineering materials. The corresponding batch of test reports can be provided for verification by the purchaser.
