20-630mm HDPE Pipe Extrusion Line with Single-screw Extruder and Vacuum Calibration for PE Pipe Production Line

The HDPE Water & Gas Pressure Pipe Extrusion Line is independently designed and manufactured by Qingdao Huashida Machinery Co., Ltd., incorporating advanced extrusion technology and years of experience in plastic pipe machinery manufacturing.

The production line is mainly used for manufacturing HDPE and PE pipes. With suitable screw, die-head and auxiliary equipment configurations, it can also process PP, PB, PERT and other thermoplastic materials.

The pipes produced feature excellent flexibility, high mechanical strength, corrosion resistance, environmental stress crack resistance and long service life.

The production line is widely used in municipal water supply, natural gas transportation, agricultural irrigation, drainage and industrial fluid transportation.

The complete HDPE pipe extrusion line mainly consists of the following equipment:

1. Single Screw Extruder
2. Extrusion Die-Head
3. Vacuum Calibration Tank
4. Spray Cooling Tank
5. Haul-off Machine
6. No-Dust Cutting Machine
7. Automatic Discharging Rack

Optimized screw and barrel design ensures excellent plasticizing performance, stable output and continuous production.

The vacuum calibration system ensures accurate pipe diameter, good roundness and consistent product dimensions.

The specially designed extrusion die-head allows precise adjustment of pipe wall thickness.

Frequency-controlled haul-off ensures synchronized operation and stable pipe production.

Automatic length measurement and no-dust cutting provide accurate cutting and improve production efficiency.

The pneumatic discharging rack automatically unloads finished pipes, reducing manual operation.

The production line can be customized according to pipe diameter, wall thickness, material, production capacity and customer requirements.

Note: Customized production solutions and larger pipe diameter configurations are available upon request.

The extruder consists of an AC motor, hardened gearbox, screw and barrel system, heating and cooling system, and electrical control system. It provides stable plasticizing and continuous extrusion for different plastic materials.

The die-head consists of a mandrel, mold neck, spiral body, die body, cover and heating elements. Its inner surface is polished and chrome-plated to ensure smooth material flow and prevent corrosion. Wall thickness can be adjusted through adjustment bolts.

The vacuum calibration tank consists of a stainless steel tank, vacuum system, spray cooling system and movable adjustment device. Vacuum pressure helps the extruded pipe fit closely against the calibration sleeve, ensuring accurate outer diameter and roundness.

The spray cooling tank uses multiple water nozzles to cool the pipe evenly from different directions, ensuring complete cooling and stable pipe forming.

The haul-off machine adopts a frequency-controlled driving system and traction structure. Its adjustable traction speed matches the extrusion speed. An automatic length measuring system controls the cutting process.

The cutting machine adopts a blade punching principle to achieve clean and accurate cutting with minimal dust. It includes a cutting device, clamping device, synchronous moving mechanism and supporting frame.

The discharging rack features a stainless steel supporting surface and pneumatic overturning mechanism for automatic pipe unloading and collection.
