Product Description

Product Description

Our HDPE pre - insulated pipe extruder is developed by Qingdao Huashida Machinery Co., Ltd., integrating advanced German extrusion technology. The line combines an extruder, vacuum calibrating system, cooling, pulling, cutting, and stacking functions, offering excellent automatic operation, extrusion capacity, stability, and durability. Compared with lines using internal pressure methods, our vacuum calibrating method significantly improves pipe stiffness, pressure resistance, and surface smoothness.

 

The vacuum calibrating pre - insulated pipe extrusion line is one of the most advanced and widely used machines globally. It is perfect for producing energy - efficient, trenchless laying pipelines with thermal insulation. The produced pipes, consisting of a steel or galvanized steel carrier pipe, a polyurethane foam insulation layer, and an outer protective shell of HDPE or galvanized steel, provide excellent rigidity and insulation properties.

Our Advantages

 

• Enhanced Pipe Properties: Vacuum calibration improves pipe stiffness, flexibility, and mechanical strength, ensuring better performance in various applications.
• High Intelligence: The high - degree automation reduces labor costs and boosts production efficiency, giving you a competitive edge.
• Fast Production Speed: 30% faster than similar equipment, increasing your throughput and productivity.
• Durability: High - quality hardware and software minimize maintenance costs, ensuring long - term stable operation.

Machine Advantages

• High - efficiency Extruder: Delivers large output with stable performance, ensuring consistent production quality.
• Smooth Pipe Walls: Reduces raw material waste, and the pipe thickness is adjustable to meet different project needs.
• No Edge Trimming: Achieves one - time forming, eliminating the need for additional trimming and saving time and labor.
• High Automation: Can be operated by a single person, significantly reducing labor costs.

Working Conditions

• Electric Source: 3 - phase, 380V (±10%, +5%), 50Hz
• Total Power: ~160kW
• Cooling Water: ≤20ºC, ≥0.3Mpa, 26 - 30 m³/h
• Compressed Air: 0.4m³/min, >0.5MPa
• Dimension: 24m x 3m x 3m
• Material: HDPE Granules

Applications

Our HDPE pre - insulated pipe extrusion line is widely used in district heating, hot and chilled water piping systems, gas pipelines, water mains, geothermal heating, and other fields for producing protective jackets of thermal insulated pipes.

Pipe Usage

The pipes produced by our line are designed for thermal insulation purposes and are widely applied in central heating, oil, natural gas, and other industrial sectors. The pipe/jacket diameter range is 110 - 1200mm, making it suitable for a wide variety of applications.

Features

 

• High - efficiency Single Screw Extruder: Equipped with a barrier & mixing head and a new - model barrel with slotting (channel), ensuring good gelation, large output, and stable performance.
• Die - head: The inner surface in contact with plastic materials is polished and chrome - plated for smooth material flow and rust prevention. The uniformity of pipe wall thickness can be adjusted by bolts, and the copper calibrating sleeve cools and calibrates the pipe's outer diameter.
• Vacuum Calibration Tank: Composed of a frame, stainless steel tank, vacuum system, spray cooling system, and position adjustment device. The vacuum pump pressurizes the pipe to ensure the correct diameter, and spray nozzles provide all - round cooling.
• Hauling Machine: Driven by an AC motor with frequency conversion control, it can adapt to different extrusion speeds, ensuring smooth operation.
• No - Dust Cutter: Utilizes the blade punching principle for dust - free cutting, with cutting, clamping, and synchronous movement devices for high efficiency.
• Control System: Controlled by an advanced Siemens PLC system with a user - friendly interface. All technical parameters can be set and monitored via a touch screen, and customizable control systems are available.
