MPP pipes and pipe fittings are structural wall plastic pipes and pipe fittings made through a vacuum forming process using modified polypropylene (MPP) as the main raw material. It has the following characteristics:
High cost performance: MPP pipes and fittings have a corrugated outer wall structure, which can save 40% to 70% of material costs compared with MPP solid-wall pipes with the same specifications and ring stiffness requirements.
High ring stiffness: Due to the special single-wall corrugated structure design and high elastic modulus materials, it has high ring stiffness. During construction, there is no need to use cement to encapsulate the outside of the pipeline. Pipe pillows and fine sand can be used directly to backfill, which greatly reduces construction costs.
Smooth inner wall: The inner surface of MPP pipes and fittings has a single-wall corrugated structure, which is in point contact with the cable, resulting in low drag resistance, which reduces the difficulty of construction.
High resistance to settlement: The unique single-wall corrugated structure makes it highly flexible and can adapt to ground settlement or changes in the construction foundation to ensure the protection of cables.
High insulation: The main material of MPP is polypropylene, which does not conduct electricity or heat. It has good insulation properties and meets the requirements for safe use of high-voltage electricity.
Environmental performance: MPP pipes and fittings are more environmentally friendly than the traditional "trenching and buried pipe method". There is no need to dig up a large amount of soil or destroy the current road surface. This construction method is more in line with environmental protection requirements.
Wide scope of application: MPP power pipe is also called MPP power cable protection pipe. The lengths of MPP power pipes commonly used in the market are 6m, 9m or 12m each. Of course, these wall thicknesses are not static. During the actual construction process, the length, diameter and wall thickness of MPP pipes can be customized according to actual needs.
In short, MPP pipes and fittings have the characteristics of high cost performance, high ring stiffness, smooth inner wall, high resistance to settlement, high insulation, environmental protection performance and wide application range. They are excellent pipes and fittings for power protection.
