Problems needing attention in the production of PE pipe by PE three-layer co-extrusion pipe equipment


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 is very sanitary, non-toxic, does not contain heavy metal additives, does not scale, does not breed bacteria, and solves the problem of secondary pollution of drinking water. Its light weight ensures the convenience of transportation and installation. The inner wall is smooth, the friction coefficient is low, and has excellent wear resistance. The unique electric fusion connection, hot-melt butt joint and hot-melt socket connection technology make the interface strength higher than the pipe body, ensuring the safety and reliability of the interface.


Many customers have many questions about PE pipes. Let's take a look at the quality requirements of PE pipes during processing? What problems need to be paid attention to?


Generally, the service temperature of PE pipes shall not exceed 45 . Because it is mainly used in the fields of gas transmission and distribution and municipal water supply, as well as in indoor cold water transmission, sewage discharge, irrigation, aquaculture, etc., the extruder of PE pipe shall be selected in the production of PE pipe, the screw shall be constructed with barrier and mixing head, and the barrel shall be a new slotted barrel, which has good plasticization and mixing effect, large extrusion capacity and very stable.


Generally speaking, for the processing of pipes in PE pipe production line, the quality of pipes should be guaranteed, and continuous innovation should be carried out. In the production and processing of pipes, we should pay attention to the accurate processing method of each process, and carry out strict quality inspection requirements. We should not neglect the details in the production process in order to improve work efficiency.


At the same time, the staff of the production line should also have the training of corresponding skills and management skills, constantly discuss their production skills, and have a reasonable management system. In terms of enterprises, we must first have a relatively suitable production environment. Some equipment of the production line is relatively complete and has a certain production capacity. We must have high-quality goods and pay attention to the cultivation of skilled talents.


On the processing process of PE three-layer co-extrusion pipe equipment, only by doing a good job in quality can we win the market test!
