Modified polypropylene (MPP pipe) power protection sleeve, without a large amount of dredging, digging and damage to the road surface, in the road, railway, buildings, river bed and other special sections of the laying of pipelines, cables and other construction projects. Compared with the traditional "digging and burying method", trenchless engineering is more suitable for the current environmental protection requirements, removing the dust, traffic congestion and other disturbing factors caused by traditional construction. This technology can also lay pipelines in some areas where excavation cannot be implemented, such as historic monument protection areas, downtown areas, crop and farmland protection areas, highways, rivers and so on. MPP pipe can be widely used in municipal, telecommunications, electric power, gas, water, heat and other pipeline projects.
The modified polypropylene MPP power protection sleeve has the characteristics of high temperature resistance and external pressure resistance, which is suitable for high voltage transmission wire and cable row pipe above 10KV. The common specification of the pipe is medium 110~ medium 250, which is divided into ordinary type and reinforced type.
Ordinary MPP pipe is suitable for excavation laying construction and trenchless crossing construction buried depth of less than 4M projects; The reinforced type is suitable for trenchless crossing construction; Works with a depth greater than 4M. MPP tube products have passed the test of the National Chemical Building Materials Testing Center, and the promotion and application have achieved good social and economic benefits.

MPP Power protection sleeve Features:
1, with excellent electrical insulation.
2, with high thermal deformation temperature and low temperature impact performance.
3. The tensile and compressive properties are higher than HDPE pipes.
4, light weight, smooth, small friction resistance, hot fusion welding butt.
5, long-term use temperature -5~70℃.
Main use
1, urban and rural trenchless horizontal directional drilling cable piping project, and open excavation cable piping project.
2, urban and rural trenchless horizontal directional drilling sewage, pipe engineering.
3. Industrial wastewater discharge project.
Construction instruction
1. It is strictly prohibited to throw, hit, carve and expose during pipe transportation and construction.
2, the two pipe axes should be aligned when the hot melt butt, and the end cutting should be vertically flat.
3, processing temperature, time, pressure, depending on the climate to adjust accordingly.
4, MPP pipe minimum bending radius should be ≥75 pipe diameter.
