The American Society Of Mechanical Engineers (ASME) develops standards to provide consistency and ensure public safety and reliability. While these codes are not always required, they have been widely adopted and implemented across many industries. As a result, it is important to be knowledgeable and aware of these standards prior to beginning a job.

How To Achieve A Proper Bead When Using A Roll Bead Expander

Single roll beading expanders simultaneously expand and bead the tube ends in firetube boiler applications. This tool accomplishes the creation of a pressure-tight tube-to-tube sheet joint, and a beaded tube end, by utilizing the natural feed force built into the expander to push the beading roll against the end of the tube while expansion is taking place.

Is the free speed RPM of a torque control the best indicator of how fast a tube can be rolled?

For 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.
