How to Achieve Long-Term Safe Operation and Production Capacity Improvement for PE Gas/Water Pipe Production Lines?

Ningbo Fangli Technology Co., Ltd. is a mechanical equipment manufacturer with over 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”.

The HDPE gas/water pipe extrusion production line achieves 30% energy savings: an optimized screw structure combined with a reverse slotting design in the feeding section ensures high production capacity while enabling low-temperature melting and even plasticization of the material. The extruder heating system provides rapid warm-up, and the main servo motor delivers excellent energy efficiency at equivalent output.

Core Advantages:

▶ The HDPE gas/water pipe extrusion line can produce two-layer, three-layer, multi-layer composite pipes, or reinforced composite pipes by changing the pipe die and increasing the number of single-screw extruders.

▶ The die of the HDPE gas/water pipe extrusion line is made from 40Cr die steel, tempered, forged, and hard chrome-plated, offering greater wear resistance, high deformation resistance, and precision.

▶ The vacuum calibration tank and spray cooling tank maintain stable vacuum, providing uniform cooling around the pipe and ensuring sufficient cooling length.

▶ Special screw design enables fast heating, and the main servo motor ensures significant energy savings at the same extrusion output.

▶ The HDPE gas/water pipe extrusion line is equipped with a German INOEX gravimetric dosing unit for highly accurate meter weight control, improving pipe quality.

▶ A well-designed haul-off structure keeps the pipe aligned with the haul-off center at all times, allowing easy user adjustment.

▶ The fully automatic chipless cutter produces pipe ends that are smooth, flat, noiseless, dust-free, and low in energy consumption, reducing waste and saving material for users.

▶ The Siemens PLC control system allows operating parameters to be freely defined and displayed on the screen.

Applications:

Pipes produced by this line offer clear performance advantages in stiffness, flexibility, heat resistance, aging resistance, mechanical strength, creep resistance, corrosion resistance, and thermal weldability.

They are widely used in urban water supply networks, drinking water pipelines in urban and rural areas, industrial fluid transport lines for chemical, food, forestry, light industry, and papermaking sectors, agricultural irrigation pipelines, postal and telecommunication conduits, power cable protection sleeves, mining slurry transport pipelines, and similar applications.
