QTech-Machinery’s PPR Pipe Extrusion Line

PPR Pipe Extrusion Line Video Introduction

This video introduces a customized PPR pipe extrusion line developed by QTech-Machinery for a customer in the plumbing and plastic pipe manufacturing industry. The production line is designed for making PP and PPR pipes from Φ20mm to Φ110mm, supporting stable output, accurate pipe dimensions and efficient long-term operation.

Through this video, viewers can understand the complete PPR pipe production process, including single-screw extrusion, color marking, vacuum calibration, spray cooling, caterpillar haul-off and no-chip cutting. It also shows how QTech-Machinery configures a pipe extrusion solution based on the customer’s pipe diameter range, output target, material, local voltage, automation level and application requirements.

Project Background

Customer Requirement

The customer needed a high-efficiency PPR pipe extrusion line to improve production capability in the plumbing industry. The line had to support a wide diameter range, deliver consistent product quality and use durable components for reliable long-term production.

Key requirements included:

• Production of PPR pipes from Φ20mm to Φ110mm
• Suitable processing for PP and PPR materials
• High production efficiency with controlled energy consumption
• Stable pipe dimensions and surface quality
• Advanced automation for easier operation
• Robust machine construction for long service life
• Clean and accurate pipe cutting
• Optional color marking for product identification

QTech-Machinery Solution

QTech-Machinery supplied a complete PPR pipe extrusion line centered on an SJ75/33 single screw extruder. The system also includes a color marking extruder, vacuum calibration tank, spray cooling tank, three-jaw caterpillar haul-off, no-chip cutting machine and automated electrical control system.

The line was configured to improve plasticizing quality, enhance cooling efficiency, maintain dimensional stability and provide clean cutting for PP/PPR pipe production.

What Visitors Can See in the Video

Complete PPR Pipe Production Flow

The video shows the complete production process from raw material extrusion to pipe shaping, cooling, hauling and cutting. It helps buyers understand how each section works together to produce high-quality PPR pipes.

Efficient Single-Screw Extrusion

The SJ75/33 single screw extruder is the core of the line. Its 75mm screw, 33:1 L/D ratio and optimized BM screw structure help ensure high plasticization, stable material output and uniform melt quality.

Color Marking for Pipe Identification

The SJ25/25 color marking extruder can add a colored line to the pipe surface. This is useful for product identification, brand differentiation and market requirements.

Vacuum Calibration and Spray Cooling

The 6-meter vacuum calibration tank helps maintain pipe roundness and dimensional accuracy, while the 6-meter spray cooling tank provides rapid and uniform cooling. This combination supports stable pipe quality during continuous production.

Stable Haul-Off and Clean Cutting

The three-jaw caterpillar haul-off machine provides steady traction with an adjustable speed range of 0.2-15 m/min. The no-chip cutting machine cuts pipes from Φ20mm to Φ110mm cleanly and accurately, reducing material waste and improving finished product appearance.
