percentages ( ≥ 6 %), with tapered roll expansion producing more pronounced shear banding . As a result , parallel pin expansion could reduce the likelihood of this type of failure from occurring by limiting the stress imparted on to the surface during expansion . Elliott Tool Technologies is committed to finding solutions to industry problems and committed to continuing to improve the body of knowledge of heat exchanger fabrication . Some points for future study include examining the mandrel rotation speed and mandrel drive speed in parallel pin mode , as well as looking at the overlap area in step rolling applications .
