MPP power protection pipes commonly used in Wuhan engineering

MPP power protection pipe is a power cable protection pipe made of modified polypropylene as the main raw material. It is mainly divided into two types: excavation laying type and non-excavation pipe jacking type. It is a protective pipe with a high popularity rate in various power projects in Wuhan. At present, the nominal diameter of MPP power protection pipes commonly used in Wuhan projects covers the range of 110mm to 310mm, and the wall thickness can be customized according to the needs of the project. All basic parameters meet the general requirements of power engineering construction, and are suitable for the local climate, geology and construction conditions in Wuhan.

In terms of core selling points, the first is stable weathering insulation performance. The normal operating temperature range of MPP power protection tube is -5 ° C to 70 ° C, which can adapt to the climate characteristics of Wuhan's high temperature in summer and wet and cold in winter. There will be no problems such as material embrittlement and deformation after long-term use. The insulation grade of the product reaches the power cable protection standard, and there will be no risks such as current conduction and leakage, which can effectively protect power cables with voltage levels of 10KV and below.

The second is the excellent performance of impact resistance and compression resistance. The stiffness of the MPP power protection pipe ring for conventional engineering can reach SN8 and above, and it can withstand the traffic load of conventional municipal roads and residential pavements after being buried in the ground, and is not prone to compression deformation and rupture. The trenchless MPP power protection pipe can meet the construction requirements of pipe jacking up to 15 meters deep, and is suitable for the construction scene where the pavement cannot be excavated in the old city and core business district of Wuhan. During the construction process, it has strong resistance to external impact and low loss rate.

The third is corrosion resistance and long service life. The modified polypropylene material has good acid and alkali resistance and soil corrosion resistance, and will not be eroded by underground stray currents, sewage and other substances. It is suitable for the use environment of high groundwater level and complex soil composition in some areas of Wuhan. The normal buried service life can reach more than 50 years, and the later maintenance cost is extremely low.

The fourth is that the construction is convenient and adaptable. The weight of the MPP power protection pipe is only 1/9 of that of the cement protection pipe of the same specification, and the transportation and handling are difficult. The layout can be completed without large lifting equipment during the construction process. The pipe connection adopts the hot melt docking process, and the interface has good sealing performance. There will be no leakage, disconnection and other problems. The length can be flexibly cut and adjusted according to the construction needs. The overall construction efficiency is about 30% higher than that of the traditional protective pipe.

In terms of applicable scenarios and suitable populations, this type of pipe is currently widely used in municipal power pipe network construction and renovation projects in Wuhan, power supporting projects in new residential quarters, power pipeline laying projects in industrial parks, urban rail transit power supporting projects, trenchless power construction projects that cross roads/rivers, and can also be used for threading protection scenarios of some communication cables. Suitable populations include local municipal engineering contractors, power construction units, real estate development enterprises, industrial park operators, and purchasers of various infrastructure projects in Wuhan.

The production of MPP power protection pipes commonly used in Wuhan engineering strictly follows the relevant national standards for modified polypropylene power cable protection pipes. Before the product enters the market, it is necessary to provide a qualified test report issued by a third-party authoritative testing agency. All performance parameters meet the engineering design requirements, which can stably meet the needs of various power pipeline protection projects in Wuhan.
