The MPP pipe, or Modified Polypropylene Pipe, stands as a pinnacle of modern polymer engineering. Meticulously crafted from polypropylene (PP), its performance is elevated through an advanced modification process. This exceptional pipe is prominently utilized in cable protection projects across pivotal sectors such as electricity and communications. Praised for its outstanding characteristics, MPP pipe is the top choice for safeguarding power cables, excelling in high temperature resistance, pressure tolerance, and environmental sustainability. Its robust design is particularly advantageous for trenchless projects and challenging environments, ensuring reliability and durability.
- High Temperature Resistance:
With an impressive working temperature range spanning from -5ºC to 120ºC, and the capability to withstand short-term temperatures up to 150ºC (notably during cable overloads), it surpasses the limits of CPVC, which caps at 70ºC. This makes it an ideal choice for high-heat applications.
- High Compressive Strength:
Boasting a ring stiffness of ≥8kN/m² at the common level, it is engineered to endure substantial ground load and the pressure of construction machinery, ensuring steadfast performance in demanding conditions.
- Corrosion Resistance:
Designed to resist the corrosive effects of acids, alkalis, salt sprays, and organic substances, this pipe is perfectly suited for chemical zones, sewage treatment facilities, and other harsh environments, delivering long-term reliability.
- Good Insulation:
Featuring high volume resistivity, this pipe effectively prevents current leakage, thereby safeguarding power systems and enhancing operational safety.
- Environmentally Friendly and Non-Toxic:
Crafted from recyclable raw materials and free from heavy metal additives, the MPP pipe adheres to RoHS standards, reflecting our commitment to sustainability and health safety.

Installation steps (hot melt connection):
1. Cutting: Employ a specialized cutter to guarantee that the end of the pipe is impeccably straight, setting the foundation for seamless connections.
2. Heating: Precisely regulate the temperature of the hot melt machine's heating plate to 200±10ºC. Adjust the heating duration according to the pipe's wall thickness, typically ranging from 30 to 60 seconds, to ensure optimal fusion.
3. Docking: Rapidly apply pressure to the docking joint and sustain this pressure until the cooling and shaping process is complete, ensuring a robust and secure connection.
Other connection methods:
1. Socket connection: Ideal for smaller pipe diameters (DN≤110mm), this method requires a rubber sealing ring to maintain tightness and prevent leaks.
2. Flange connection: Specifically designed for interfacing with inspection wells or equipment interfaces, providing a reliable and adaptable connection solution.
