Is the free speed RPM of a torque control the best indicator of how fast a tube can be rolled?
Erica Dzomba2019-11-25T14:11:44-05:00For tube expanding it is desirable to roll the tube quickly as it prevents work hardening of the tube and less frictional heat is generated. The limiting factors in this balance of speed vs. power are voltage or pneumatic pressure. These either limit the speed or power being produced.
How To Prevent Tubes From Rotating When Rolling
Erica Dzomba2019-11-25T14:11:44-05:00Tube rolling occurs when the tube rotates due to inadequate friction between the tube OD and the hole in the tube sheet. This can cause increased expansion times and decrease the efficiency of the operator. Increasing the friction between the tube and tube sheet and or collar the tube will not rotate within the tube sheet. Increasing the friction can be done using several different methods:

Keller & Associates Inc. Finds The Best Bead In The Market
Erica Dzomba2019-11-25T14:11:55-05:00Elliott’s Single Roll Beading Expander saves Keller & Associates on labor costs as compared with the manual method of using an air hammer and beading tool which takes three operations instead of one.
What Is Parallel Pin Expansion?
Erica Dzomba2024-08-14T15:11:22-05:00With parallel pin expansion, the rolls are set parallel with the mandrel with zero feed angle. This means that the mandrel will not self-feed as a traditional expander would. Instead, the mandrel is pushed through the expander by force, in most cases hydraulic, allowing the tube to expand.
Best Practices For Extending Expander Tool Life
Erica Dzomba2020-03-05T10:08:09-05:00To ensure high-quality tube expansions, the tube wall must be reduced by a predetermined percentage and be consistent with each expansion. In order to complete the job efficiently, it is important to achieve the maximum expander tool life in order to reduce cost and downtime.
Challenges Created Due To Over-Rolling A Tube
Erica Dzomba2019-11-25T14:11:56-05:00A mechanical tube joint is formed when the outer diameter of the tube is compressed against a fixed container. Rolling to the proper wall reduction will decrease the chances of under rolling and over rolling a tube, creating higher quality mechanical joints.
