PE pipe extrusion line and manufacturing process

Ningbo Fangli Technology Co., Ltd. is a mechanical equipment manufacturer with nearly 30 years’ experiences of plastic pipe extrusion equipment, new environmental protection and new materials equipment. Since its establishment Fangli has been developed based on user’s demands. Through continuous improvement, independent R&D on the core technology and digestion & absorption of advanced technology and other means, we have developed PVC pipe extrusion line, PP-R pipe extrusion line, PE water supply / gas pipe extrusion line, which was recommended by the Chinese Ministry of Construction to replace imported products. We have gained the title of “First-class Brand in Zhejiang Province”.

PE pipe extrusion line has unique structure, high degree of automation, convenient operation, stable and reliable continuous production.

The pipes produced by the plastic pipe extrusion line have moderate rigidity, strength, good flexibility, creep resistance, environmental stress cracking resistance and good thermal welding performance, and have become the first choice for urban gas pipelines and outdoor water supply pipes. 

Composition of PE pipe extrusion line:

The pipe extrusion line is composed of a control system, an extruder, a machine head, a shaping cooling system, a tractor, a planetary cutting device and a turning frame. Each pipe extrusion line has two extruders. One of the main extruders uses powerful conveying bushings and high-efficiency screws, and the other smaller extruder is used to extrude the marking line.

Mould and auxiliary machine: The machine head adopts the latest designed basket machine head or spiral split-flow extruded pipe composite machine head, which has the characteristics of convenient adjustment and uniform discharge. The sizing sleeve adopts a unique slotting process and water ring cooling to ensure the forming accuracy of the pipe.

The PE pipe extrusion line adopts PE high-efficiency screw, slotted barrel, and powerful water jacket cooling, which greatly improves the conveying capacity and ensures efficient extrusion; high-torque vertical structure gear box; DC drive motor.

The basket composite die head suitable for polyolefin processing not only ensures the stability of high-efficiency extrusion, but also achieves the minimum stress and the highest pipe quality brought about by the low melt temperature.

High-efficiency double-cavity vacuum sizing technology and spray cooling water tank are used to increase the yield of pipes and meet the needs of high-speed production.

The multi-track tractor is adopted, and the traction is even and stable. Each track is driven by an independent AC servo motor, and the drive technology controlled by a digital controller realizes accurate speed adjustment to achieve a high degree of synchronization.

The cutting machine adopts high-speed and precise design, the cutting section is flat, and is equipped with a powerful chip suction device to minimize maintenance.

Advantage:

PE pipe extrusion line is mainly used to produce HDPE pipes of various pipe diameters and wall thicknesses, such as agriculture, construction and cable laying. The device consists of a conical twin-screw extruder, vacuum mode (such as two) composed of claws, three claws and so on.

Application:

PE pipes used for sewage treatment are also called HDPE pipes. This kind of pipe is often used as the first choice for municipal engineering, mainly used in the sewage treatment industry. Because of its wear resistance, acid resistance, corrosion resistance, high temperature resistance, high pressure resistance, etc., especially because of its light weight, it has gradually replaced traditional pipelines such as steel pipes and cement pipes. Light weight, easy to install and move, this is the first choice for new materials.

When choosing pipes of this material, users should pay special attention to the following points:

1. Special attention should be paid to the selection of raw materials for plastic pipes. There are thousands of brands of polyethylene raw materials, and the prices of raw materials on the market are as low as thousands of yuan per ton. Products made with this raw material cannot be built, otherwise the rework loss will be huge.

2. The selection of the pipe manufacturer should be based on the standard professional manufacturer.

3. When choosing to purchase PE pipes, check on the spot whether the manufacturer has production capacity.
