Qingdao Yongke Machinery Co., Ltd., established in 2010, is a professional manufacturer specializing in pipe extrusion equipment. Our Pre-Insulated HDPE Jacket Pipe Extrusion Machine is designed for high-efficiency production of pre-insulated pipes used in district heating, cooling systems, and industrial pipelines. Combining advanced extrusion technology with robust construction, this machine delivers consistent jacket layer quality, precise wall thickness control, and energy-saving operation. With ISO9001, ISO14000, and OHSAS18001 certifications, we ensure every unit meets international standards.
This extrusion line integrates a dedicated HDPE jacket extruder, co-extrusion crosshead, cooling trough, haul-off unit, and automatic winding or cutting system. It is capable of producing solid or foam-insulated pipes with a smooth outer HDPE jacket, suitable for both single- and multi-layer applications. The machine's modular design allows customization according to pipe diameter, wall thickness, and line speed requirements.
Key Features and Technical Specifications
High-output extruder with optimized screw design (barrier-type) to ensure uniform melting and stable discharge.
Precision co-extrusion crosshead for even distribution of HDPE jacket layer over the core pipe (PEX, steel, or aluminum).
PLC touch-screen control with Siemens or Mitsubishi components, offering real-time monitoring of temperature, pressure, speed, and layer thickness.
Energy-efficient heating/cooling system with automatic PID control reduces power consumption by up to 20% compared to conventional machines.
Double-layer die design (optional) enables simultaneous extrusion of two different materials for specialized applications.
Stainless steel cooling trough with high-efficiency spray nozzles and motorized height adjustment.
Heavy-duty haul-off unit with caterpillar belts and variable frequency drive, suitable for continuous operation.
Automatic coiler or cutter (optional) to meet different packaging requirements.

Frequently Asked Questions (FAQ)
Q: What materials can this extrusion machine process?
A: It is primarily designed for HDPE (high-density polyethylene), but can also process LDPE, LLDPE, and certain blends. The screw and barrel can be customized for different melt flow indexes.Q: What is the typical jacket thickness range?
A: The jacket thickness can be adjusted from 0.5 mm to 6 mm, depending on the pipe diameter and die design. Thicker jackets may require a slower line speed.Q: Can I produce foam-insulated pipes with this machine?
A: Yes, by adding a secondary extruder and foam injection system (optional), our machine can produce foam-insulated pipes with an HDPE jacket layer.Q: What is the minimum order quantity?
A: For standard models, one set is acceptable. Customized machines may require a minimum of one set with a deposit.Q: Do you provide installation and training?
A: Yes, we offer free installation guidance and on-site training (travel and accommodation at buyer's cost). Remote support via video call is also available.Q: What is the warranty period?
A: Typically 12 months from the date of shipment, covering manufacturing defects. Extended warranty can be negotiated.Q: How long does delivery take?
A: For standard models, delivery is 30–45 days after confirmation. Customized orders may require 45–60 days.Q: Can the machine produce PE-RT or PEX jacket pipes?
A: With appropriate screw design and temperature control, it is possible. Please consult our engineers for material compatibility.
