20-110mm PE Pipe Production Line

Small-Diameter HDPE Pipe Extrusion Line

This line is designed for PE and HDPE pipe projects where stable extrusion, accurate outside diameter, smooth pipe surface, mark-line quality and coiling performance are important.

• Pipe range: 20-110mm, project-based configuration
• Material: PE80, PE100, HDPE and polyethylene compounds
• Applications: water supply, gas, irrigation, drainage, conduit and industrial pipe

1. Single Screw Extruder

The single screw extruder is selected according to PE material, pipe size, SDR and target output. For small-diameter pipe production, stable plasticizing and smooth pipe surface are important.

• Suitable for PE80, PE100 and HDPE materials
• Output matched with 20-110mm pipe range
• Control system synchronized with downstream speed

2. Color Marking Co-extruder

A color marking co-extruder is used when water supply or gas pipe needs blue, yellow or customized mark lines. The mark line must be matched with the pipe die head and pipe standard.

• Optional blue, yellow or customized mark line
• Useful for PE water and gas pipe identification
• Matched with pipe die head and material formula

3. PE Pipe Die Head

The PE pipe die head forms the pipe diameter and wall thickness. For 20-110mm pipe production, die design affects pipe surface, concentricity and mark-line position.

• Selected by pipe diameter range and SDR
• Supports optional color mark line connection
• Designed for stable melt distribution

4. Vacuum Calibration Tank

The vacuum calibration tank controls pipe outside diameter and initial cooling. Small-diameter PE pipes need stable vacuum and water temperature for consistent size.

• Vacuum sizing for outside diameter accuracy
• Cooling matched with pipe wall thickness
• Tank length selected by production speed

5. Spray Cooling Tank

The spray cooling tank provides additional cooling before hauling and cutting. Cooling stability helps protect roundness, surface quality and line speed.

• Additional cooling for continuous pipe production
• Spray system matched with speed and diameter
• Supports stable downstream traction

6. Haul-off Machine

The haul-off machine pulls the pipe at synchronized speed. Stable traction is important for pipe wall thickness, outside diameter and coiling quality.

• Speed synchronized with extruder
• Traction structure selected by pipe size
• Supports cutting and coiling stability

7. Chipless Cutter

The chipless cutter is used when fixed-length pipe cutting is required for small-diameter PE pipe. It should be matched with pipe diameter, wall thickness and production speed.

• Clean chipless length cutting
• Independent from pipe coiler function
• Selected according to pipe wall thickness

8. Pipe Coiler

The pipe coiler is used for small-diameter PE pipe coils. Coiling design should be confirmed according to pipe diameter, coil size, pipe stiffness and packing method.

• Important for irrigation, water supply and gas pipe coils
• Coil diameter and winding method can be customized
• Works after haul-off and cutting/coiling control

Factory Workshop and Assembly

Small-diameter PE pipe production lines require careful matching between extruder, mark-line co-extruder, die head, calibration, cooling, haul-off, cutter and coiler.

Machine Parts Checking

Before delivery, moulds, calibration parts, electrical cabinet, coiler and spare parts are checked according to the final configuration list.

Export Packaging and Container Loading

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

Exhibition and Project Communication

Winsoar communicates with buyers about pipe diameter range, SDR, application, color mark line, coiling, output and factory conditions before preparing a practical quotation.

It is a small-diameter HDPE pipe extrusion line for producing polyethylene pipes from 20mm to 110mm, including extrusion, color marking, calibration, cooling, hauling, cutting and coiling.

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

A color marking co-extruder is required when the pipe needs blue, yellow or customized mark lines for water, gas or project identification.

Many small-diameter PE pipes are packed and shipped in coils. Coiler size, winding force and control method affect coil quality and packing efficiency.

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