AB Series Tube Expander
Features of AB Series Tube Expander
- High-productivity boiler tube expander designed for parallel rolling without flaring the tube ends.
- Sturdy construction with expansion rolls self-contained inside the cage.
- Time-tested and durable design provides consistent performance in demanding industrial applications.
- Integrated bearing reduces frictional buildup during tube-expansion cycles.
- Reduced friction provides smoother tool operation and helps improve expansion consistency.
- Bearing-supported construction helps increase the useful operating life of the tube expander.
- Provides accurate and uniform tube expansion for strong tube-to-tube-sheet joints.
- Suitable for high-production applications where tube-end flaring is not required.
