What are the characteristics of MPP single wall corrugated pipes?
MPP single wall corrugated pipes are widely used in our current market because they are different from other types of pipes. So, what are the advantages of MPP single wall corrugated pipes?
1. Good rigidity: MPP corrugated pipe has a high ring stiffness due to its special single wall corrugated structure design and high elastic modulus material. During construction, there is no need to use cement encapsulation on the outside of the pipeline, and it can be directly backfilled with pipe sleepers and fine sand, which greatly reduces construction dust and reduces construction costs.
2. Flexibility: The unique single wall corrugated structure of MPP corrugated pipes gives them good flexibility and can adapt to ground settlement or changes in construction foundation. * The pipes have a normal protective effect on cables.
3. Smooth: The inner and outer surfaces of MPP corrugated pipes are smooth, with low friction coefficient; Its inner surface is a single wall corrugated structure, in point contact with the cable, with low drag resistance and reduced construction difficulty.
4. Insulation: The main material of MPP corrugated pipe is 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.
5. Heat resistance: The main material of MPP corrugated pipe is polypropylene, and the Vicat softening temperature is above 120 ℃. Therefore, it can still maintain good external pressure capacity at higher temperatures, making it suitable for use as a protective sleeve for high-voltage power lines. Even when heating, cables can still be used safely and confidently.
6. Environmental protection: The main material of MPP corrugated pipes is polypropylene, mainly composed of carbon and hydrogen elements, which is hygienic and environmentally friendly. Pipe waste can be recycled twice, and there is no white pollution in the production and recycling process.
