Are aluminum and wooden plugs used to keep a plastic pipe round while threaded?

Using aluminum and wooden plugs to keep a plastic pipe round while threading is indeed a common practice. When plastic pipes are threaded, especially under conditions where the pipe might collapse or bend, these plugs serve a crucial role. They provide internal support, helping to maintain the shape of the pipe as it is being worked on. This is particularly important for ensuring that the threads are formed correctly, allowing for a proper fit when connecting different pipe sections.

Maintaining the roundness of the pipe not only facilitates effective threading but also contributes to the integrity of the connections that will be made. If the pipe were to deform during the threading process, it could lead to uneven threads or even cause damage to both the pipe and the threading equipment.

This technique is not limited to metal pipes; however, it is particularly relevant for plastic pipes, which do not have the same structural rigidity as metal options. Thus, recognizing the role of these plugs in both maintaining pipe shape and ensuring a successful threading process underscores why the statement is true.
