Tianjin Dingrunda Group Co.,Ltd Specializing in the production of PE pipes, PVC pipes and related accessories
Trenchless modified polypropylene(MPP)power cable protective pipeis made by modified polypropyl-ene as the main raw material associated with special formula and processing technique to make a new type composite pipe.It has much advantages of high strength,good high temperature resistant perfor- mance,easy installing,convenient construction,cost savings and so on.
The MPP power cable protective pipe’s features could be highlighted as a trenchless tube,which conforms to the development require- ments ofmodem cities and is suitable for buried depth of 2-18 meters.The trenchless construction technique has the characteristics of non-pollution,no impeded traffic,small damage to the underlying structure,secure construction,shortcycle,low construction cost,ensuring the reliabity andsecurity of the pipe network,reducing the failure rate of pipe network and so on.
It has remarkable social and economical benet efit and also greatly improved the city environment.The MPP power cable protective pipe could be applied to excavation and trenchless areas for protecting high pressure and ultra-high voltage power cables buried underground.
MPP (Modified Poly-Propylene) electric power tube
MPP (modified polypropylene) pipe for electrical communication cable protection is manufactured as the new type of plastic pipe adopting modified polypropylene as the main raw material and using a special formula and processing technology,with good features of high strength,temperature resistance,handling easily,convenient installation and cost saving.The modified polypropylene trenchless pipe is widely used as the protection pipe of electrical communication cable. Its characteristics is more obvious as a towing pipe. It conforms to the development requirements of modern cities and is suitable for buried depth of 2~18m.
Technology of trenchless
Technology of trenchless is widely used based on its good advantages of non pollution of environment, not affect traffic, little damage to stratigraphic texture,no need of soil transportation and pilling,cost-effective and remarkable social and economic benefits.This kind of trenchless technology not only ensures the reliability of the network and reduces the failure rate, but also makes the environment of the city greatly improved.There is no need to dig up and destroy the road surface largely.It is very suitable for laying pipelines, cables and other construction works in special areas such as roads, railways, buildings and under river etc.
Superiority:
Superiority:
1. M-PP pipe has excellent electrical insulation.
2. M-PP pipe has higher thermal deformation temperature and low temperature impact performance.
3. M-PP pipe has higher tensile and compression resistance than HDPE.
4, M-PP pipe is light, smooth, frictional resistance is small, can be hot-melt butt joint.
5, M-PP tube long-term use temperature-5 ~ 70 ºC.
6. Construction instructions
It is strictly forbidden to drop, hit, scratch, or expose to the sun during the transportation and construction of pipes.
The axis of the two pipes must be aligned during the hot-melt butt joint, and the end face cutting should be vertical and flat.
The processing temperature, time, pressure, and climate conditions are adjusted accordingly.
The minimum bending radius of the pipe should be ≥75 pipe outer diameter.
