Tube Expander

Horizontal Progressive Expander

 

HPE

 

The Horizontal Progressive Expanders use a small bore hydraulic cylinder to expand tubing in a heat exchanger coil. Single Tube Expanders consist of one cylinder that expands a single tube at a time. Single Hairpin Expanders typically consist of 3 cylinders arranged in a triangular pattern so that both legs of any hairpin may be expanded at the same time. Other configurations are available upon request, These machines are very versatile, and can be set up for different coil configurations in just a few minutes. They are also capable of providing very high expansion forces for expanding stainless steel and other exotic tubing materials.
