What does the beading process in tube formation achieve?

The beading process in tube formation is primarily designed to increase support for fittings. During this process, beads or raised rings are formed along the tube's length, which ensure a tighter and more secure fit when the tube is connected to various fittings. This added support is crucial as it helps to prevent leaks and provides structural integrity at the joint, which can be a weak point if not properly reinforced.

While beading can influence aesthetic appearance and possibly fluid flow due to changes in geometry, its foremost purpose is to enhance the connection strength between the tube and fittings, ensuring a reliable and safe assembly in fluid systems. Strengthening the entire tube can be an indirect effect, but the main goal remains the reinforcement for fitting assembly.
