What is a seamless tube drawn over?

A seamless tube is typically drawn over a mandrel, which is a solid rod or form that helps shape the tube during the manufacturing process. This method allows for the creation of tubes without welded seams, resulting in a stronger and more uniform product. The drawing process involves pulling the heated metal over the mandrel to achieve the desired diameter and wall thickness. This technique is commonly used in industries requiring high-strength components, such as aerospace and automotive manufacturing.
