5mm Double Layer White Outside Black Inside PE Small Pipe Extrusion Production Line
This 5 mm PE small pipe extrusion line is designed for producing double-layer tubing with a white outer layer and a black inner layer. The line is equipped with two SJ-40/28 single-screw extruders and one double-layer co-extrusion die head.
The production line includes extruders, a double-layer die head, a vacuum sizing tank, a traction unit, a winding unit and an electrical control system. Its designed production speed is 10–20 m/min, and the maximum extrusion capacity is approximately 30 kg/h.
The electronic meter measures the pipe length during production and allows the finished pipe to be cut according to the preset length. Machine voltage, pipe dimensions, layer structure and auxiliary equipment can be customized according to the customer’s production requirements.
Dual Extrusion System
Two SJ-40/28 single-screw extruders separately melt and feed the inner and outer PE materials to produce white-outer and black-inner double-layer pipes.
Double-Layer Co-Extrusion Die Head
Combines the materials from both extruders to form a stable double-layer pipe with uniform wall thickness and strong layer bonding
Vacuum Cooling and Sizing Tank
Uses vacuum sizing and circulating cooling water to quickly shape the pipe, ensuring consistent diameter, roundness and surface quality.
Electrical Control System
Centrally controls the extrusion temperature, production speed, haul-off unit and winding system for stable operation and convenient adjustment.
Belt Haul-Off Unit
The upper and lower belts continuously pull the pipe at a stable speed, reducing deformation and maintaining consistent wall thickness.
Electronic Length Counter
Measures the pipe length in real time and helps control the preset length of each finished roll.
Dual-Station Winder
Winds the finished pipe neatly into rolls. The dual-station design allows convenient roll changes and reduces production downtime.
Application Scenarios
Customer Case
In 2025, HWYAA partnered with a top Uzbek water-saving irrigation enterprise. Plagued by inefficiencies of traditional manual punching, the enterprise inspected HWYAA's pre-drilling line in China, confirmed satisfaction on-site, and signed the contract immediately.
HWYAA delivered the equipment as scheduled, with on-site installation, commissioning and full training provided by our engineers. The client praised: "Stable operation, easy operation, exceeding expectations" — its productivity and competitiveness improved significantly.
Driven by proven benefits and trust, the client plans to purchase all available stock.
F A Q:
Q1: What type of pipe can this production line manufacture?
This production line is designed for manufacturing 5 mm PE small pipes with a white outer layer and a black inner layer. Other colors and pipe structures can also be customized.
Q2: What is the standard pipe specification?
The standard finished pipe specification is 5 mm in diameter with a wall thickness of approximately 0.8 mm.
Q3: How is the white outer and black inner structure produced?
The line uses two SJ-40/28 single-screw extruders and a specially designed double-layer co-extrusion die head. The two extruders separately feed the outer and inner layer materials.
Q4: What raw materials can be used?
The machine is mainly suitable for PE materials. The specific material grade and formulation should be selected according to the required flexibility, strength, color and application of the finished pipe.
Q5: What is the production speed?
The designed production speed is approximately 10–20 m/min. The actual speed depends on the raw material, pipe diameter, wall thickness and production conditions.
Q6: What is the maximum extrusion capacity?
The maximum extrusion capacity is approximately 30 kg/h, depending on the selected raw material and final pipe specification.
Q7: Can the pipe diameter and wall thickness be customized?
Yes. The pipe diameter, wall thickness, layer structure and color can be customized. Please provide a pipe sample, drawing or detailed specifications before ordering.
Q8: What equipment is included in the complete production line?
The standard line includes two extruders, a double-layer co-extrusion die head, a vacuum cooling and sizing tank, a belt haul-off unit, a winding unit and an electrical control system.
Q9: Is the water chiller included?
The 5 HP water chiller is optional. We will recommend suitable auxiliary equipment according to the local temperature, cooling-water conditions and production requirements.
Q10: Can the machine voltage be customized?
Yes. The voltage and frequency can be customized according to the customer’s local power supply, such as 380 V/50 Hz or 440 V/60 Hz.
Q11: Is installation and technical support available?
Yes. We provide operating manuals, installation guidance and remote technical support. If required, our engineers can also provide on-site installation and commissioning services.
Q12: What is the warranty period?
The main mechanical parts are covered by a one-year warranty. Electrical parts are covered by a six-month warranty, excluding damage caused by improper operation or force majeure.
Q13: Can you test the machine before shipment?
Yes. We will test the complete production line before shipment. Machine photos and test videos can be provided, and customers are also welcome to visit our factory for inspection.
Q14: How can I get an accurate quotation?
Please provide the required pipe diameter, wall thickness, layer structure, raw material, production speed, voltage and winding specifications. We will prepare a suitable configuration and quotation accordingly.
