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”.


As one of the common plastic machines, the composite pipe production line needs to be regularly maintained, which should also be operated according to certain procedures and the relevant requirements of the corresponding equipment safety technical performance. This is conducive to the operation of equipment and can effectively ensure the maximum safety of equipment and personnel.


The following describes how to maintain the composite pipe production line:

1. The maintenance of screw, barrel and other important parts must be carried out according to the requirements of the manual.

2. It is necessary to regularly check the pipeline leakage of plastic pipe equipment and the fastening condition of fasteners.

3. The cooler shall be soaked and cleaned with carbon tetrachloride solution every 5 ~ 10 months.

4. Regularly check the ground wire connection, insulation of electrical components and aging of wires.

5. Always check whether the safety device of the machine is normal and effective, especially after replacing the mold, check whether the mechanical insurance has been adjusted accordingly.

6. Regularly check the reliability of the lubrication system, lubricate the moving parts as required, and check whether the oil volume of the lubricating pump oil tank and the base oil tank is sufficient.

7. The composite pipe equipment shall be regularly maintained and repaired several times according to the operation time, focusing on cleaning, lubrication, adjustment, disassembly and maintenance

8.  Regularly check the condition of oil filter screen or filler, timely clean and replace, and often pay attention to whether the oil quality is polluted and deteriorated. When the hydraulic oil turns black brown and emits odor, it is a sign of oxidation and deterioration. The hydraulic oil should be updated as soon as possible; When there are small black spots or transparent bright spots in the hydraulic oil, it indicates that impurities or metal powder are mixed, and the oil should be filtered or changed.
