Special properties of PE pipes


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”.


1. What are the corrosion resistance characteristics of PE pipes?

Polyethylene is a plastic raw material, which can resist the corrosion of various chemical media. No electrochemical reaction, no anti-corrosion coating.


2. PE pipe does not leak out?

Fusion connection (hot melt connection or electric melt connection) is the key choice of polyethylene pipeline, which essentially ensures the unity of socket material, structure and nozzle itself, and completes the integration of joint and pipe. The test confirmed that the compressive strength and engineering blasting strength of its socket are higher than that of the pipe body. Compared with rubber joints or other mechanical joints, there is no joint leakage problem.


3. High wear resistance of PE pipe?

Polyethylene pipe is a kind of pipe with high wear resistance. Its tensile strength usually exceeds 500%, and it is very adaptable to uneven settlement of pipe base. It is also a kind of pipeline with high seismic and anti-seismic grade. During the Kobe earthquake in Japan in 1995, polyethylene gas pipes and water supply pipes were spared. Therefore, after the earthquake in Japan, the application of PE pipes in the gas industry was vigorously developed.

4. PE pipe has the characteristics of high quality flexibility?

The flexibility of polyethylene enables the polyethylene pipe to be coiled and supplied in a long length without various connecting pipe fittings. With the trenchless construction technology, the direction of polyethylene pipe can be easily changed according to the provisions of the construction method, and the original size and size can be restored after construction.


5. How to understand the characteristics of PE pipe with excellent scratch resistance?

Scratches cause stress on raw materials and damage to pipelines. When the trenchless technology is selected, whether laying new pipes or replacing old pipes, scratches are difficult to avoid. Research in recent years has proved that PE80 grade polyethylene pipe has good working ability to resist slow crack growth and scratch resistance, and PE100 polyethylene pipe has better scratch resistance. Therefore, polyethylene pipes are widely used in non-excavation construction sites.
