PE Pipe Extruder Conical Twin Screw Barrel

PE products and PE pipes are usually produced using single screw extruders. But HUACHEN Screw and China’s leading extruder manufacturers have collaborated to develop energy-efficient conical twin screw barrels for PE pipe extruders.

This PE pipe extruder conical twin screw barrel has higher conveying efficiency and requires less power to install than a single screw barrel. HUACHEN’s conical twin screw barrels for PE pipe extruder are one of our most popular product lines, and we keep a lot in stock. Feel free to contact us for a quote.

PE pipe extruder conical twin screw barrel

1. Specifically developed for PE pipes and products, the conical twin screw has a special compression ratio and thread configuration. Production can be achieved with powder mix raw material direct extrusion. Compared to a single screw barrel with the same power main motor, a conical twin screw barrel nearly doubles the output. That’s almost 40% less electricity consumed in a year by the extruder, saving producers a lot of money.

2. Conical twin screws designed for PE are low-shear and high-conveyance. Basic output and pipe production speed are much higher than with a single screw barrel, which allows for in-line flaring and other flow operations. The screw barrel set can produce large solid wall PE pipes, double wall corrugated PE pipes, PE winding pipes, and wood-plastic PE sheets.

3. There are venting ports on the conical barrel. It helps overcome the problem of air bubbles on the inside and outside of the pipes because of moisture in raw materials.

4. Improved wear resistance of the screw and barrel. Screw barrel made from high quality 38CrMoAlA, which is rigorously tempered and nitrided. Next, the conical twin screw’s vulnerable parts get bimetallic alloy treatment. We can supply you with SKD sleeve fitted barrel of higher quality. PE pipe conical twin screw barrels offer extremely high wear and corrosion resistance and increased service life.
