MPP pipe (Modified Polypropylene Pipe) is a state-of-the-art polymer pipeline, innovatively enhanced through a meticulous modification process based on premium polypropylene (PP). It is predominantly utilized in cable protection projects, making it an indispensable asset in the realms of electricity, communications, and beyond. Esteemed for its exceptional high-temperature resilience, remarkable pressure endurance, and eco-friendly attributes, MPP pipe has emerged as the preferred choice for power cable protection. It excels in trenchless construction projects and thrives in the most demanding environments.
- High Temperature Resistance:
Operating within an impressive temperature range of -5ºC to 120ºC, and capable of withstanding short-term spikes up to an astonishing 150ºC during instances of cable overload, this pipe outperforms other materials like CPVC, which is limited to a maximum of 70ºC.
- High Compressive Strength:
Engineered with a formidable ring stiffness of ≥8kN/m² at the common level, MPP pipes are designed to endure substantial ground loads and withstand the weight of construction machinery with ease.
- Corrosion Resistance:
Crafted to resist the corrosive effects of acids, alkalis, salt spray, and organic substances, this pipe is ideal for deployment in chemical zones, sewage treatment facilities, and other challenging environments.
- Excellent Insulation:
Featuring high volume resistivity, these pipes are engineered to prevent current leakage, thereby ensuring unparalleled electrical safety.
- Environmentally Friendly and Non-toxic:
Manufactured from recyclable raw materials, devoid of harmful heavy metal additives, and in full compliance with RoHS standards, these pipes champion sustainability and safety.

Installation Steps for Hot Melt Connection:
1. Cutting: Ensure precision and perfection by using a specialized cutter to achieve a flawlessly straight pipe end.
2. Heating: Carefully control the hot melt machine's heating plate at a precise temperature range of 200±10ºC. Adjust the heating time according to the wall thickness, typically ranging from 30 to 60 seconds, for optimal results.
3. Docking: Rapidly apply pressure during the docking process and maintain it until the connection is fully cooled and shaped to perfection.
Other Connection Methods:
1. Socket Connection: Perfect for smaller pipe diameters (DN≤110mm), this method requires the use of a durable rubber sealing ring to ensure a tight fit.
2. Flange Connection: Ideal for connecting with inspection wells or various equipment interfaces, providing a robust and adaptable solution.
