- What are the corrosion resistance characteristics of PEX Expansion Fittings?
Polyethylene is an inert material and can withstand the erosion of a variety of chemical media. No electrochemical corrosion, no anti-corrosion layer.
- The non-leakage characteristics of PE pipes?
Polyethylene pipes mainly adopt welding connection (hot-melt connection or electro-fusion connection), which essentially guarantees the identity of the interface material, structure and the pipe body itself, and realizes the integration of the joint and the pipe. Experiments have confirmed that the tensile strength and blasting strength of the interface are higher than the pipe body. Compared with rubber joints or other mechanical joints, there is no joint leakage problem.
- What are the high toughness characteristics of PE pipes from PEX Crimp Fitting manufacturers?
Polyethylene pipe is a kind of high-toughness pipe, its elongation at break generally exceeds 500%, and its adaptability to uneven settlement of the pipe base is very strong. It is also a kind of pipeline with excellent seismic performance. In the Kobe earthquake in Japan in 1995, polyethylene gas pipes and water supply pipes were the piping systems that survived. Therefore, after the earthquake in Japan, the use of PE pipes in the gas field was promoted vigorously.
