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.
