Internally threaded copper pipes are grooves cut on the inner wall of copper pipes, similar to the threads on bolts. They are generally used in condensers or radiators to increase the contact area between the liquid flowing through the pipeline and the pipe wall, thereby improving heat exchange efficiency.
Compared to ordinary copper pipes, the area of the inner wall of internally threaded copper pipes has increased significantly. On copper pipes of the same length, the heat exchange efficiency of internally threaded copper pipes is much higher.
