Description


TwinScrew’s PPR Pipe Extrusion Line is designed for producing polypropylene random copolymer (PPR) pipes.
PPR pipes are widely used in domestic hot/cold water supply, central heating, chemical fluid transport, and industrial pipelines due to their high temperature resistance, durability, chemical stability, environmental safety, and long service life.
TwinScrew offers a complete production system that ensures stable extrusion performance and high product consistency, allowing customers to achieve efficient and reliable production.


What Is a PPR Pipe Extrusion Line?

A PPR pipe extrusion line typically uses a single screw extruder to melt and plasticize PPR material.
The melted material passes through a pipe die and sizing sleeve, then enters a vacuum calibration tank to achieve accurate sizing. Afterward, the pipe goes through a cooling tank to complete the cooling process.
The haul-off unit provides continuous pulling force, while the planetary cutter ensures clean and accurate cutting. The finished pipes are transferred to the stacker.
The entire line is controlled via a PLC system, ensuring synchronized operation, stable extrusion output, and consistent pipe quality.
TwinScrew’s PPR line offers stable dimensions, excellent roundness, smooth surfaces, and uniform wall thickness. It is suitable for producing household piping, commercial piping, industrial piping, and irrigation piping.


Key Advantages of TwinScrew PPR Pipe Extrusion Line

1. High Extrusion Efficiency

The optimized single screw extruder ensures uniform plasticizing of PPR material, giving the pipe consistent wall thickness and stable quality.

2. Energy-Saving Heating System

A multi-zone PID heating system provides precise temperature control, reducing energy consumption while maintaining high productivity.

3. Precision Sizing & Cooling

Multi-stage vacuum calibration and spray cooling systems ensure dimensional accuracy and smooth pipe surfaces, improving overall product consistency.

4. Servo-Controlled Haul-Off & Clean Cutting

The servo haul-off unit ensures stable pulling force, while the planetary cutter provides clean, dust-free cutting for smooth pipe ends.

5. Optional In-Line Socketing

Automatic socketing equipment can be added for in-line pipe socket forming, reducing downstream processing time.

6. Smart PLC Control System

A PC/PLC integrated control platform simplifies operation and supports recipe storage, quick changeovers, monitoring, and real-time alarm functions.

7. Wide Diameter Range

Capable of producing 16–110 mm PPR pipes (and larger diameters for extended needs), suitable for residential, commercial, and industrial applications.

FAQ

Q1. What is the difference between PPR pipes and PP/PE pipes?

PPR pipes have better heat resistance and are suitable for hot-water systems.
PP/PE pipes are more commonly used for cold water, irrigation, or gas systems.

Q2. Can this line produce multilayer reinforced PPR pipes?

Yes. With a co-extruder, it can produce PPR-GF-PPR multilayer pipes, offering improved pressure resistance and reduced thermal expansion.

Q3. How is dimensional accuracy ensured?

The vacuum calibration tank ensures accurate pipe diameter.
Spray cooling tanks stabilize pipe roundness, while the servo haul-off and planetary cutter maintain stable line speed and clean cutting.
