Φ110–400mm PPH Pipe Extrusion Line

Φ110–400mm PPH Pipe Extrusion Line

Project Overview

This video presents the running test of a Φ110–400mm PPH pipe extrusion line supplied by QTech-Machinery for an overseas customer. The production line is designed for large-diameter PPH pipe manufacturing, covering the complete process from extrusion to vacuum calibration, spray cooling, servo haul-off, ring cutting and pipe discharge.

Complete PPH Pipe Production Process

From Extrusion to Finished Pipe Handling

The video shows the full workflow of the PPH pipe extrusion line. PPH material is plasticized and extruded by the SJ90 single screw extruder, then enters the pipe mould for forming. After extrusion, the pipe passes through the vacuum calibration tank for accurate sizing and initial cooling.

The pipe is further cooled by the spray cooling tank, pulled forward by the four-caterpillar servo haul-off machine, cut to the required length by the ring cutting machine, and finally transferred to the discharge rack for collection.

Key Machine Configuration

Main Technical Specifications

SJ90 Single Screw Extruder

Stable Plasticizing for PPH Material

The SJ90 single screw extruder is the main extrusion unit of the production line. It is designed for stable plasticizing and continuous extrusion of PPH material.

Key features include:

• 38CrMoAlA screw and barrel
• Flender gearbox
• 6 barrel heating zones
• 25 die heating zones
• Fan cooling system
• Siemens PLC control
• 15-inch touch screen operation
• 110kW servo motor
• Swing-arm control cabinet for convenient operation

Vacuum Calibration and Spray Cooling System

Accurate Pipe Sizing and Efficient Cooling

The line uses a 9m vacuum calibration tank for pipe sizing and initial cooling. The tank is made of SUS304 stainless steel with a thickness of 5mm, providing strong durability and corrosion resistance.

The vacuum tank adopts a two-chamber vacuum sizing structure, helping the pipe maintain accurate diameter and roundness after extrusion. The 6m spray cooling tank further cools the pipe surface and improves pipe stability before hauling and cutting.

Four-Caterpillar Servo Haul-Off Machine

Stable Traction for Large-Diameter Pipes

The four-caterpillar servo haul-off machine provides strong and stable traction for Φ110–400mm PPH pipes. Each caterpillar is driven by a servo motor, allowing accurate speed control and synchronized hauling.

Main advantages:

• Four-caterpillar structure for stable pipe clamping
• Maximum traction force: 20000N
• Haul-off speed: 0.1–5m/min
• Servo-controlled speed adjustment
• Real-time line speed display
• Pneumatic upper clamping
• Motorized lower lifting

Φ110–400mm Ring Cutting Machine

Smooth Cutting for Thick-Wall PPH Pipes

The ring cutting machine is designed for large-diameter pipe cutting. It supports pipe sizes from Φ110mm to Φ400mm and can cut pipes with a maximum wall thickness of 50mm.

The machine uses an imported SKD11 cutting blade, Siemens PLC control and touch screen operation. The cutting process is stable, accurate and suitable for thick-wall PPH pipes.

Application of the PPH Pipe Extrusion Line

Suitable for Industrial Pipe Production

This Φ110–400mm PPH pipe extrusion line is suitable for producing large-diameter PPH pipes used in industrial pipeline systems.

Typical applications include:

• Chemical fluid transportation
• Industrial drainage systems
• Corrosion-resistant pipeline projects
• Ventilation and exhaust pipe systems
• Environmental protection engineering pipelines
