Multi-Layer PPR Water Supply Pipe Extrusion Production Line
Introduction:
pipe extrusion line specially designed for PPR pipe making, also supply PPR pipe production line
These final product pipe are mainly used in the area of agricultural water supply system, architectural water supply system, gas pipe, sewages pipes,pavement of cables,etc.
The main parts of the line are PLC control, high degree of automation .
Adopting compound spiral engine head , effectively deleting memory function of the material .
Adopting co-extrusion head to improve the tube color line.
Vacuum calibration , constant temperature control , eliminating pipe stress.
High extrusion capacity, low temperature of melt , equal temperature of melt.
Wide processing range of raw materials.
For different diameter range pipe,will be equipped with corresponding different production lines.
we can supply PE pipe production lines for diameter:
16mm,20mm,25mm,32mm,40mm,50mm,63mm,75mm,90mm,110mm,
125mm,160mm,200mm,250mm,280mm,315mm,
355mm,400mm,450mm,500mm,550mm,630mm.

Material Feeding & Drying
PPR resin pellets and barrier layer materials (e.g., EVOH, aluminum) are fed into separate hoppers and dried to remove moisture.
Co-Extrusion
Multiple extruders melt and extrude different layers simultaneously.
A special multi-layer die head combines the molten materials into a single pipe structure with PPR inner/outer layers + middle barrier layer.
Vacuum Calibration & Cooling
The pipe passes through a vacuum calibration tank to fix dimensions.
Spray or immersion cooling tanks rapidly cool the pipe for solidification.
Hauling & Cutting
A servo-controlled haul-off unit pulls the pipe smoothly.
An auto-cutting machine cuts pipes to required lengths.
Printing & Stacking
Inkjet/laser printing marks pipe specifications (size, pressure rating, standards).
An automatic stacking system organizes finished pipes for packaging.
Quality Testing
Hydrostatic pressure test, wall thickness measurement, and ovality check ensure compliance with industry standards.
Features
The Multi-Layer PPR Water Supply Pipe Extrusion Production Line is an advanced manufacturing system designed to produce high-performance multi-layer Polypropylene Random Copolymer (PPR) pipes with enhanced strength, durability, and thermal stability. These pipes are widely used in hot & cold water supply, HVAC systems, and industrial fluid transport, offering superior leak-proof performance and long service life.
By combining multiple layers (PPR + adhesive + barrier layers), the pipes achieve better pressure resistance, reduced thermal expansion, and improved oxygen barrier properties compared to single-layer PPR pipes. The production line features high automation, precision control, and energy efficiency, ensuring consistent quality that meets international standards (ISO 15874, DIN 8077/8078).
