Can PE pipe be directly threaded?

In the installation and construction of plastic pipes, there are often questions about the connection method, among which "can PE pipes be directly threaded?" is a question that has attracted much attention. The answer is no, PE pipes cannot be directly threaded under normal circumstances.

PE pipe, that is, polyethylene pipe, its material characteristics determine that it is not suitable for the traditional threaded connection process. PE pipe has good flexibility and corrosion resistance, but at the same time its rigidity is relatively low. Threaded connections require cutting at the end of the pipe. This process will cause damage to the pipe structure of the PE pipe, which can easily lead to stress concentration at the thread of the pipe, which can lead to cracking, leakage and other problems. In addition, the thermal expansion coefficient of PE pipe is large, and it is difficult to ensure long-term sealing performance and structural stability of the sleeve wire connection. Under the action of water pressure or when the temperature changes, the connection is prone to loosening, which affects the safe operation of the entire pipeline system.

Since PE pipe cannot be directly threaded, what reliable connection methods do it usually use? At present, the mainstream connection methods of PE pipe include hot-melt butt connection and electrofusion connection. Hot-melt butt connection is to heat the ends of two PE pipes to a molten state, quickly fit and press them, and form a firm whole after cooling. This connection method is suitable for large-diameter PE pipes, and has the advantages of high connection strength, good sealing performance, and convenient construction. Electrofusion connection is through the electric resistance wire inside the electrofusion pipe fittings to heat up, so that the contact surface between the pipe fittings and the pipe is melted, so as to achieve a close combination of the two. Electrofusion connection is suitable for PE pipes of various diameters, especially in pipeline emergency repair, pipe fittings and pipe connections and connections under complex working conditions. Its connection quality is stable and reliable, and it is less affected by human factors.
