PPR Three Layers Pipe Making Machine 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.

Extrusion line details:

Loader → Dryer → Single-screw Extruder→ Mould→ Vacuum &Spraying Cooling Tank →Hauling-off → Cutter/Winder → Pipe stacker

Material Feeding & Drying

PPR resin pellets are loaded into the hopper and automatically fed into the drying system to remove moisture, ensuring optimal extrusion quality.

Extrusion

The dried material is melted in a single-screw or twin-screw extruder with precise temperature control.

The molten PPR is pushed through a pipe die head to form a continuous pipe shape.

Vacuum Calibration & Cooling

The pipe enters a vacuum calibration tank to stabilize the diameter and wall thickness.

It then passes through a cooling water tank to solidify the structure.

Hauling & Cutting

A haul-off machine pulls the pipe at a controlled speed to maintain uniformity.

An automatic cutting machine cuts the pipe to the required lengths.

Printing & Stacking

A printing machine marks the pipe with specifications (size, pressure rating, brand, etc.).

The finished pipes are collected by an automatic stacking machine for packaging.

Quality Inspection

Each pipe undergoes dimensional checks, pressure testing, and visual inspection to ensure compliance with industry standards.

Features

Enhanced Durability & Strength

The three-layer co-extrusion structure (PPR + adhesive layer + outer protective layer) improves impact resistance, pressure endurance, and long-term performance.

Superior Leak & Corrosion Resistance

The middle adhesive layer ensures perfect bonding between layers, preventing delamination and leakage.

Outer protective layer shields against UV rays, chemicals, and abrasion, extending pipe lifespan.

Energy Efficiency & Insulation

The multi-layer design provides better thermal insulation, reducing heat loss in hot water applications.

High Precision & Consistency

Advanced co-extrusion technology ensures uniform wall thickness and smooth inner/outer surfaces for optimal fluid flow.

Cost-Effective Production

Automated extrusion control minimizes material waste and labor costs while maintaining high output speeds.

Wide Application Range

Suitable for hot/cold water systems, heating networks, and industrial pipelines with varying pressure requirements.

Compliance with International Standards

Meets ISO 15874, DIN 8077/8078, and other certifications for quality assurance.

Low Maintenance & User-Friendly Operation

PLC-controlled system with real-time monitoring ensures stable production with minimal downtime.
