Can the hot PE pipe be rotated?

It is generally not recommended to rotate the PE pipe when ironing. Keeping the pipe stable is the key to ensure the quality of the connection.

the hot melt connection of the PE pipe is to heat the connection part of the pipe and the pipe fitting to the molten state through a special hot melt equipment, and then quickly connect and apply a certain pressure to make the two fully fused. After cooling, a firm and sealed whole is formed. In this process, accurate operation and stable pipe position are essential. When the PE pipe is heated to the appropriate temperature, the surface of the pipe is in a softened state and the molecular chain becomes active. If the pipe is rotated at this time, the connection part that has been aligned will be misaligned, which will destroy the accuracy of the hot melt connection. Once misalignment occurs, uniform and comprehensive fusion cannot be achieved between the pipe and the pipe fitting, resulting in gaps in the connection part.

turning the pipe can also cause the connection to be not tight. The principle of hot melt connection is that the molecules of the pipe and the molten part of the pipe are diffused and entangled with each other, thus forming a high-strength connection. Rotation behavior will interfere with the orderly diffusion of molecules, making the molecular chains unable to intertwine effectively, reducing the connection strength. For PE rural irrigation pipes used for rural irrigation, if the connection is not tight, under the action of water pressure, leakage may occur at the connection, affecting irrigation efficiency; for PE drinking water pipes for transporting drinking water, the connection may not be tight, which may lead to water pollution and threaten the safety of residents' water.

In addition, turning the pipe when ironing the PE pipe may also cause a series of chain problems. For example, the torque generated by rotation may generate stress concentration inside the pipe, making the pipe more prone to rupture due to factors such as pressure and temperature changes during subsequent use. Especially in some large-scale water supply and drainage projects, a large number of PE water supply pipes are used. Once a connection has quality problems due to rotation, it will not only affect the water supply in local areas, but also consume a lot of manpower, material resources and time costs for maintenance.
