The MPP Cable Conduit Extruder for Pipes is a high-performance manufacturing system specifically engineered for producing modified polypropylene (MPP) conduits—critical components in protecting underground cables from mechanical damage, moisture, and environmental stress. Its design focuses on delivering superior pipe mechanical properties and high production efficiency, addressing the growing demand for reliable cable protection in power grids, telecom networks, and renewable energy installations.

At its core is a specialized screw design with a 33:1 L/D ratio, optimized for MPP material processing to ensure uniform melt distribution and consistent material properties. Paired with a high-torque gearbox (15,000 N·m), this extruder achieves exceptional impact resistance (Charpy V-notch ≥25 kJ/m²) and long-term chemical stability—key requirements for underground conduit applications. The system supports multi-layer co-extrusion (up to 3 layers), enabling integration of recycled materials in inner layers while maintaining structural integrity with virgin MPP in outer layers. With precision vacuum calibration (±0.1 mm diameter tolerance) and production speeds up to 60 m/min, it efficiently manufactures DN80-DN250 mm pipes that comply with GB/T 19472.1 and ASTM F2300 standards, making it a versatile solution for diverse infrastructure projects.
Material Compatibility: Primarily processes MPP (modified polypropylene) with melt flow rate 0.5-3.0 g/10min (230°C/2.16kg), with additional compatibility for PP-R and PE materials. Supports recycled content up to 30% in multi-layer configurations without compromising mechanical performance.
Extrusion System: φ90-φ120 mm single-screw extruder featuring a grooved feed section for improved material feeding and a barrier-type screw design for efficient melting. Delivers 300-600 kg/h output with stable melt pressure (5-15 MPa).
Die Design: Spiral mandrel die with internal flow channels that ensure low-pressure extrusion (≤10 MPa), resulting in a smooth inner surface (Ra ≤0.8 μm) to minimize cable pulling friction. Die lips are adjustable for precise wall thickness control.
Vacuum Calibration Tank: Multi-zone cooling (3-5 independent zones) with adjustable vacuum pressure (0.02-0.08 MPa) to ensure dimensional stability. Tank length of 3-6 meters accommodates different cooling requirements based on pipe diameter and speed.
Hauling Unit: Servo-driven caterpillar with 6-12 pairs of polyurethane-coated rollers that provide uniform gripping without marking the pipe surface. Delivers 10-50 kN traction force with speed accuracy ±0.5%.
Cutting System: Flying saw with PLC-controlled positioning achieving ±0.5 mm length accuracy, equipped with a dust collection system to manage cutting debris. Supports automatic length measurement and batch counting.
PLC+HMI Interface: 15-inch touchscreen provides real-time monitoring of melt temperature (180-230°C, ±2°C accuracy), pipe diameter (via laser scanning), and production speed (5-60 m/min). Stores 100+ production recipes for different pipe sizes.
Energy Efficiency: Equipped with IE4 premium efficiency motors and variable frequency drives that reduce power consumption by 20% compared to standard systems. Includes heat recovery from extruder cooling to preheat process water.
Power Grid Construction
Manufactures MPP conduits for 110kV and 220kV cable laying in urban and suburban areas, with high compressive strength (≥8 MPa) to withstand soil pressure and traffic loads.
Supports horizontal directional drilling (HDD) installations with bend radius ≤12D (where D is pipe diameter), enabling trenchless cable laying under roads, rivers, and buildings.
Telecom Infrastructure
Produces multi-duct systems for fiber optic cable networks, with UV resistance (ISO 4892-3, 3000-hour exposure) and rodent protection (incorporating repellent additives in outer layers).
Manufactures micro-duct bundles for FTTH (Fiber to the Home) deployments, ensuring precise dimensional control for easy cable blowing.
Industrial Drainage
Processes chemical-resistant MPP pipes for industrial wastewater and chemical transport systems, complying with AS/NZS 4130 for chemical resistance to acids, alkalis, and solvents.
Creates non-toxic conduits for food processing facilities, meeting FDA 21 CFR 177.1520 standards for food contact materials.
Renewable Energy
Constructs solar farm conduits with low thermal conductivity (≤0.4 W/m·K), minimizing heat-induced expansion/contraction that could damage cables.
Produces wind farm cable protection systems resistant to vibration and extreme temperature cycles (-40°C to 80°C).
Q: What is the maximum pipe length this extruder can produce?
A: It supports continuous extrusion with customizable cutting lengths from 1 meter up to 12 meters, with automatic length adjustment via the PLC system. Longer lengths can be accommodated with extended haul-off and cutting units.
Q: Can it handle recycled MPP materials?
A: Yes, with an upgraded screen changer (150-mesh filtration) and high-shear mixing elements in the extruder, it efficiently processes up to 30% recycled MPP content in multi-layer pipes. The outer layer remains virgin material to ensure UV resistance and mechanical strength.
Q: What certifications does the MPP conduit hold?
A: The produced MPP conduits comply with CE (Machinery Directive 2006/42/EC), UL 651A for electrical non-conductivity and flame resistance, and ISO 9001:2015 for quality management. Specific project certifications (e.g., KEMA, SGS) can be arranged upon request.
Q: How long does it take to change between different pipe diameters?
A: With the quick-change die system and pre-stored recipes, diameter changeovers between standard sizes (e.g., DN110 to DN160) can be completed in 30-45 minutes, including die replacement, calibration, and parameter setup.
