315-800mm PE Pipe Production Line

1. Single Screw Extruder

The single screw extruder is selected according to PE80/PE100 material, diameter range, SDR and target output. For large diameter pipe production, screw design, gearbox torque and stable plasticizing are critical.

• Classical 33D or high-efficiency 38D options
• Output range matched with SDR and wall thickness
• Temperature control and melt stability affect pipe quality

2. Color Marking Co-extruder

The color marking co-extruder adds color stripes to HDPE pipes, such as blue mark lines for water supply pipe and yellow mark lines for gas pipe. It is an optional but important unit when the pipe standard or customer project requires visual identification.

• Optional mark line for water, gas and project identification
• Matched with the main die head and PE material
• Useful for customers comparing complete PE pipe production line configuration

3. Pipe Die Head

The pipe die head forms pipe diameter and wall thickness. For 315-800mm HDPE pipe projects, die head structure, melt distribution and heating zones must be selected according to pipe diameter range, SDR and material output.

• Correct die head image and configuration
• Diameter tooling selected by pipe range
• Spiral die design supports stable melt distribution
• Color mark line connection can be matched when required

4. Vacuum Calibration Tank

The vacuum calibration tank controls outside diameter, roundness and initial cooling. Large HDPE pipes need stable vacuum, sufficient tank length and reliable water circulation.

• Vacuum sizing for OD accuracy
• Cooling length matched with thick-wall pipes
• Independent filters and water level control by project

5. Spray Cooling Tank

Additional spray cooling keeps pipe dimensions stable before hauling and cutting. For 315-800mm pipe, cooling capacity is one of the main factors affecting real production speed.

• Extended cooling for thick-wall HDPE pipe
• Water temperature and spray layout matched with output
• Supports stable continuous operation

6. Haul-off Machine

The haul-off machine pulls heavy PE pipe at synchronized speed. Caterpillar number and clamping structure should be selected by pipe diameter, wall thickness and pipe weight.

• Strong traction for large diameter pipe
• Speed synchronized with extruder and cutter
• Stable clamping helps reduce pipe deformation

7. Planetary Cutter

The planetary cutter is used for fixed-length cutting of large diameter PE and HDPE pipes. Cutting mode should be selected according to pipe wall thickness, chip control and cutting length accuracy.

• Automatic length control
• Suitable for large-diameter PE / HDPE pipe cutting
• Matched with haul-off speed and pipe wall thickness

8. Pipe Stacker / Turnover Rack

The pipe stacker or turnover rack is a separate downstream handling unit after cutting. It supports finished PE pipes and helps transfer them away from the cutting area according to pipe length and workshop layout.

• Separate from the planetary cutter
• Supports and transfers finished PE pipes
• Selected according to pipe length, diameter and factory layout

Factory Workshop and Assembly

Winsoar checks the extruder, color marking co-extruder when selected, vacuum tanks, spray cooling tanks, haul-off, cutter and control system matching before shipment. Large-diameter PE projects need careful layout review.

Machine Parts Checking

Moulds, calibration parts, electrical cabinet, spare parts, mark line unit and configuration list should be checked against the final quotation before delivery.

Export Packaging and Container Loading

Packaging and loading plans are arranged according to equipment dimensions, tank length, shipment route and unloading conditions.

Exhibition and Project Communication

Before quotation, Winsoar communicates with buyers about pipe diameter range, SDR, application, output, voltage, factory conditions and color mark-line requirements.

It is a large-diameter HDPE pipe extrusion line for producing polyethylene pipes from 315mm to 800mm, including extrusion, optional color marking, calibration, cooling, hauling, cutting and stacking.

Many PE water supply and gas pipe projects require color stripes for pipe identification. The color marking co-extruder is selected when the project standard or customer specification requires blue, yellow or other mark lines.

The final extruder should be selected according to pipe diameter range, SDR, wall thickness, output requirement and PE material grade. The full 33D and 38D parameter tables help compare available model ranges.

Yes. The configuration can be selected for PE water supply pipes, PE gas pipes, drainage pipes and industrial pipe projects according to pipe standard and SDR.

Please provide pipe diameter range, SDR or wall thickness, material grade, pipe application, output target, voltage, workshop layout and color mark-line requirement.
