What happens here

Before applying heat, an internal bending spring must be inserted into the PVC conduit. This long, flexible metal spring is specifically designed for the conduit's diameter (e.g., 3-inch) and is pushed into the section of the pipe that will be heated and bent. The purpose of the spring is to provide internal support, preventing the PVC walls from collapsing, kinking, or flattening as it becomes soft during heating and is shaped into a bend.

Goal: Place the bending spring inside the conduit to maintain its shape during bending.
