Do you know the special characteristics of PE Plastic Tube Core?

PE is polyethylene plastic, a basic plastic, plastic bags, and plastic wrap are PE, HDPE is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin section. PE has excellent resistance to most domestic and industrial chemicals. Welding of PE Plastic Core, PE plastic tube core pipe butt weld, this method provides reliability and range of diameters and pressure processes: the end of the heated tube, using a tool called contact pressure and temperature defined under "Mirror".

1. What is the corrosion resistance of PE Plastic Tube Core?

Polyethylene is an inert material that can withstand the attack of many chemical media. No electrochemical corrosion, no need for anticorrosive coating.

2. What are the characteristics of PE plastic tube core not leaking?

Polyethylene pipes are mainly welded (hot-melt or electric-fused), which essentially guarantees the identity of the interface material and structure with the pipe itself, and realizes the integration of joints and pipes. Experiments have confirmed that the tensile strength and burst strength of the interface are higher than the pipe body. Compared with rubber joints or other mechanical joints, there is no joint leakage problem.

3. High toughness characteristics of PE plastic tube core ?

Polyethylene pipe is a kind of pipe with high toughness. Its elongation at break generally exceeds 500%, and its ability to adapt to uneven settlement of the pipe base is very strong. It is also a kind of pipeline with excellent seismic performance. During the 1995 Kobe earthquake in Japan, polyethylene gas pipes and water supply pipes were spared. Therefore, after the earthquake in Japan, the use of PE pipes in the gas field was vigorously promoted.

4. PE plastic tube core has excellent flexibility characteristics?

The flexibility of polyethylene allows polyethylene pipes to be coiled and supplied in longer lengths without the need for various connection fittings. For non-excavation construction, the orientation of the polyethylene pipe can be easily changed according to the requirements of the construction method, and the original size and dimensions can be restored after the construction is completed.

5. How to understand the characteristics of PE plastic tube core with good resistance to scratches?

Scratches cause stress concentration in the material and cause pipeline damage. When using non-excavation technology, whether it is laying new pipes or replacing old pipes, scratches are more difficult to avoid. Recent studies have proven that PE80 grade polyethylene pipes have better resistance to slow crack growth and scratch resistance, and PE100 polyethylene pipes have better scratch resistance. Therefore, polyethylene pipes are very common in non-excavation construction.

6, PE plastic tube core has good fast crack propagation resistance characteristics?

Rapid cracking of a pipeline is an occasional accident. The crack rapidly grows at a certain rate, causing the pipeline to rupture tens of meters or even thousands of kilometers in an instant. The resulting consequences are catastrophic. As early as the 1950s, several rapid cracking accidents occurred in gas pipelines in the United States. In actual use, no rapid cracking of polyethylene gas pipes has been found. In recent years, a lot of researches have been conducted on the rapid cracking of pipes in the world. The results show that the ability of polyethylene pipes to resist rapid crack propagation is among the best.
