Modified Polypropylene (MPP) double wall corrugated pipes for power cable protection are a new type of structural wall plastic pipes made from modified polypropylene as the main raw material, using a composite reinforced modified special formula and processing technology. They have a series of advantages such as novel structure, high strength, good temperature resistance, simple construction, and cost saving. As a new industry product for excavation power pipes, this pipe solves industry difficulties such as process molding difficulties and material composite reinforcement and modification. It creatively designs novel product structures and button connection methods. Therefore, this technology has broad application prospects.

FEATURES

      1、High cost-effectiveness: MPP double wall corrugated pipe is made of modified polypropylene, which is currently the lightest material among all buried pipes. Under the premise of achieving the same performance, fewer materials can be added to save material costs. Compared with MPP pipes with the same ring stiffness requirements, it saves 40% to 70% in material costs.

      2、Good rigidity: MPP double wall corrugated pipe has a high ring stiffness due to its special high elastic modulus material, which is three times higher than that of ordinary PVC corrugated pipe. Without special requirements for working conditions, the outside of the pipeline does not need to be sealed with cement during construction, and can be directly filled with pipe sleepers and fine sand, which greatly reduces construction dust and reduces construction costs.

      3、Smooth: The inner and outer surfaces of MPP double wall corrugated pipes are smooth, with low friction coefficient; Low drag resistance reduces construction difficulty.

      4、Flexibility: The unique corrugated structure of MPP double wall corrugated pipes gives them good flexibility and can adapt to ground settlement or changes in construction foundation, ensuring the normal protective effect of the pipes on the cables.

      5、Heat resistance: The main material of MPP double flange corrugated pipe is modified polypropylene, and the Vicat softening temperature is above 120 ℃. Therefore, it can still maintain good external pressure resistance at higher temperatures and is suitable for use as a protective sleeve for high-voltage power lines, ensuring that the cable can still be used safely and confidently even when heated.

6、Low temperature resistance: MPP double wall corrugated pipes have good low-temperature impact resistance, and have better impact resistance when subjected to unexpected impacts at lower temperatures during construction or use in the south.

      7、Insulation: The main material of MPP double wall corrugated pipe is modified polypropylene, which is non-conductive and non heat transfer. It has good insulation performance and meets the requirements for safe use of high-voltage power.

      8、Corrosion resistance: The main material of MPP double wall corrugated pipes is modified polypropylene, which has the advantages of corrosion resistance and acid alkali resistance. There is no acid alkali neutralization corrosion of fiberglass steel pipes or acid corrosion of metal pipes, and the service life can reach up to fifty years.

      9、Sealable: MPP double wall corrugated pipes can be connected by hot melt connection and special clamps. The former is sealed by wave peak butt welding, while the latter is elastic sealing. There are no welding seams or flash edges of other pipes, and the cables will not be scratched or cut during dragging.

      10、Environmental protection: The main material of MPP double corrugated pipe is modified polypropylene, mainly composed of carbon and hydrogen elements, which is hygienic and environmentally friendly. Pipe waste can be recycled and reused, and there is no white pollution in the production and recycling process.
