Some of the most overlooked best practices of tube expansion involves the use of pre-expansion tools. In order to create a better mechanical joint and prolong tool life, it is important that the appropriate pre-expansion tools are used.
CTI’s operators were pleased to find that the Midi-Torq and Maxi-Torq were perfect for their job application. The motors supported the tube OD range, torque range, and production rate required for their work. Additionally, the motors were very durable and reliable, essential for CTI since a large part of their work is performed in the field, all over the world.
Between less tool replacements and faster cycle times, the manufacturer was able to save significant production time by using the 24 Series Expanders.
With Elliott’s 24 Series Expander, this fabricator experienced a significant increase in tool life and ease of use, reducing rework and hassles.
Elliott’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.
US Fabricator Metalforms challenge was threefold: improve consistency while maintaining their high-quality standards, decrease the overall cost of the process, and increase the safety of their employees, in order to maintain a competitive edge in the marketplace.
The manufacturer with the widest chiller solution and service portfolio in the world was working to overcome some challenges. Their main concern was regarding their employee’s health. The Sr Manufacturing and Environmental Engineer and the operators are amazed at the difference the Rapid Hawk has made in improving the ergonomics of the rolling process and absorbing the torque from the motor.
With 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.
The design of the wet pass boiler can be frustrating for Boilermakers due to the limited access to install tubes in the combustion return area of the boiler.
To 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.
