Our state-of-the-art MPP Conduit Pipe is a marvel of modern engineering. Crafted from Modified Polypropylene (MPP), it stands as a testament to innovation, enhancing the inherent qualities of polypropylene for superior performance. Perfectly designed for the rigors of cable protection projects across diverse sectors like electricity and communications, our MPP pipe emerges as the ultimate choice for power cable protection. Its extraordinary resistance to high temperatures and pressures, combined with its eco-friendly attributes, make it exceptionally suited for trenchless projects and the most demanding environments.
- Exceptional High Temperature Resistance:
Boasting a notable working temperature range of -5ºC to 120ºC, our MPP pipe demonstrates remarkable resilience. It can even endure short-term spikes up to 150ºC, such as during cable overloads, outshining CPVC pipes which cap at 70ºC. This makes it perfect for challenging thermal conditions.
- Superior High Compressive Strength:
Engineered for durability, with a ring stiffness of ≥8kN/m² (common level), it is robust enough to withstand substantial ground loads and the pressure of construction machinery, affirming its reliability and strength in demanding scenarios.
- Outstanding Corrosion Resistance:
Our MPP pipe is expertly resistant to corrosive substances like acid, alkali, salt spray, and organic compounds, making it ideal for installation in chemical zones, sewage treatment plants, and similarly challenging environments.
- Superior Insulation Properties:
With its high volume resistivity, this pipe expertly prevents current leakage, maintaining optimal power safety and ensuring reliable performance across all applications.
- Eco-Friendly and Non-Toxic:
Crafted from recyclable raw materials and free from harmful heavy metal additives, our MPP pipe aligns with stringent RoHS standards, standing as an environmentally responsible choice that doesn't compromise on safety or sustainability.

Installation Steps (Hot Melt Connection):
1. Cutting: Utilize a specialized cutter to achieve a perfectly straight pipe end, ensuring precision in every cut.
2. Heating: Set the hot melt machine's heating plate to a precise temperature of 200±10ºC. Adjust the heating time based on wall thickness, typically between 30-60 seconds, for optimal results.
3. Docking: Swiftly apply pressure to the docked pipes and maintain it until they have cooled and taken shape, ensuring a seamless connection.
Other Connection Methods:
1. Socket Connection: Ideal for smaller pipe diameters (DN≤110mm), this method requires a rubber sealing ring for a tight, leak-proof fit.
2. Flange Connection: Perfect for linking to inspection wells or equipment interfaces, offering robust and secure connectivity.
