Plastic PPR Pipe Extrusion Making Production Line

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.
