Plastic PPR Pipe Extrusion Making Production Line
Introduction:
The Plastic PPR Pipe Extrusion Production Line is a
state-of-the-art manufacturing system designed for the continuous
production of high-quality Polypropylene Random Copolymer (PPR)
pipes. These pipes are widely used in hot and cold water supply,
heating systems, and industrial fluid transportation due to their
excellent heat resistance, corrosion resistance, and long service
life.
Our extrusion line ensures precise control over pipe dimensions,
wall thickness, and mechanical properties, delivering consistent
and durable PPR pipes that meet international standards (such as
ISO 15874, DIN 8077/8078). The production line features advanced
automation, energy efficiency, and user-friendly operation, making
it ideal for large-scale pipe manufacturing.
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.
