MPP high and low voltage 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.

MPP high and low voltage power pipe

2、 Applicable Scope of MPP Power Pipe

● MPP power pipe can be widely used in municipal, telecommunication, power, gas, tap water, heat and other pipeline projects.

● MPP power pipeline urban and rural trenchless horizontal directional drilling power pipeline engineering, and open excavation power pipeline engineering.

● MPP power pipe urban and rural trenchless horizontal directional drilling sewage drainage works. Industrial wastewater discharge project.

3、 Advantages of MPP Power Pipe

1. MPP power pipe has excellent electrical insulation.

2. MPP power pipe has high thermal deformation temperature and low temperature impact performance.

3. MPP power pipe has higher tensile and compressive properties than HDPE

4. MPP power pipe is light, smooth, with small friction force, and can be welded by hot fusion.

5. The long-term service temperature of MPP power pipe is 5~70 ℃.

4、 Construction Instructions for MPP Power Pipe

● During the transportation and construction of MPP power pipe, it is strictly prohibited to throw, hit, scratch and expose to the sun at will.

● The axes of the two pipes shall be aligned and the end cutting shall be vertical and flat when the MPP power pipes are butt welded by hot melting.

● The processing temperature, time, pressure and temperature of MPP power pipe shall be adjusted according to the climatic conditions.

● The minimum bending radius of MPP power pipe shall be ≥ 75 pipe outer diameter.
