  • Process of making variable wall thickness tubing
    Publication number: 20060112558
    Abstract: A method for manufacturing a tube with varying wall thickness includes the step of drawing a tube over a generally cylindrical mandrel having an outer diameter that fluctuates along the length of the mandrel between a first diameter and a second diameter. The tube is drawn over the mandrel to form a tube wall having a thickness that fluctuates along the length of the tube between a first wall thickness and a second wall thickness. After the tube is drawn over the mandrel, the mandrel is removed from the tube. The outer surface of the tube may be finished to form a substantially uniform outer diameter along the length of the tube.
