Maus 5R/80 & 5R/81 Tube Expander Series
Five-Roller Systems for Thick Tubesheets
Precision for Thick Tubesheets
The Maus 5R/80 and 5R/81 series are engineered for the high-precision mechanical expansion of thin-walled tubes into thick tubesheets. The five-roller architecture provides superior stability and uniform radial compression, making these tools essential for maintenance in industrial heat exchangers, boilers, and condensers.
Key Advantages
- • Extended Depth: Capable of reaching expansion depths up to 203.2 mm.
- • Distortion Control: 5-roller design minimizes tube wall deformation.
- • Industrial Build: Alloy-steel construction for long-term reliability.
Technical Specifications
| Metric | 5R/80 Series | 5R/81 Series |
|---|---|---|
| Tube Ø | 15.9–38.1 mm | 15.9–38.1 mm |
| Exp. Depth | 9.5–184.2 mm | 28.6–203.2 mm |
| Roller Length | 38.1 mm | 57.1 mm |
Note: By integrating these expanders with a torque-controlled drive, you ensure the exact expansion torque is applied uniformly across the entire length of the thick tubesheet, guaranteeing a professional-grade, leak-free seal.
