National standard MPP pipe

The pipe is also called the power cable protection pipe and is divided into excavation type and non-excavation type. The non-excavation pipe is also called jacking pipe or tow pipe. The pipe uses modified polypropylene as the main raw material. It has the characteristics of high temperature resistance and external pressure resistance, and is suitable for the above high-voltage transmission line and cable row pipes.

< br/>Introduction
_ Editor
Using modified polypropylene as the main raw material, it does not require a large amount of dredging, excavation and damage to the road surface. It can be used under roads, railways, buildings, river beds, etc. Construction projects such as laying pipelines and cables in special areas. Compared with the traditional method of digging trenches and burying pipes, trenchless power pipe projects are more adaptable to current environmental protection requirements and eliminate the nuisance factors such as dust and traffic congestion caused by traditional construction. This technology can also be used in some areas where excavation is not possible. Pipelines are laid in areas of operation, such as historical protection areas, downtown areas, crop and farmland protection areas, highways, rivers, etc.
The common specifications of pipes are ~medium diameter, divided into ordinary type and reinforced type. The ordinary type is suitable for excavation and paving construction and trenchless crossing construction projects with a burial depth of less than 1. The enhanced type is suitable for trenchless crossing construction projects with a burial depth of greater than 1. This product has passed the testing of the National Chemical Building Materials Testing Center and has achieved good social and economic benefits.
Scope of application
_ Edit
It can be widely used in pipeline projects such as municipal administration, telecommunications, electricity, gas, tap water, and heat.
Urban and rural non-excavation horizontal directional drilling power pipe drainage projects, and open excavation power pipe drainage projects.
Urban and rural non-excavation horizontal directional drilling sewerage and sewage pipe projects. Industrial wastewater discharge project.
Advantages of tubes
_ Editor
Tubes have excellent electrical insulation.
The tube has high heat deformation temperature and low temperature impact performance.
The pipe has high tensile and compressive properties.
The pipe is light, smooth, has little friction, and can be hot-melt welded butt jointed.
The long-term use temperature of the pipe is 1~℃.
, Construction Instructions
During the transportation and construction of pipes, it is strictly prohibited to throw, hit, score, or expose them to the sun.
During hot-melt butt jointing, the axes of the two tubes must be aligned, and the end faces must be cut vertically and flat.
The processing temperature, time, and pressure will be adjusted accordingly depending on the climate conditions.
The minimum bending radius of the pipe should be the outer diameter of the pipe.
