Maus R/50 & R/51 Tube Expander Series

High-Precision Expansion for Thick Tubesheets

Engineered for Thick Material

The Maus R/50 and R/51 series are designed specifically to handle the challenges of thick tubesheets in industrial heat exchangers, boilers, and condensers. Featuring an extended expansion depth capability of up to 171.5 mm, these tools ensure deep, consistent, and uniform sealing that meets rigorous industrial standards.

Key Advantages

• Extended Reach: Adjustable depths suited for thick, heavy-duty sheets.
• High Durability: Alloy-steel construction designed for frequent industrial use.
• Repeatable Quality: Compatible with Maus torque-controlled drives to ensure exact expansion force.

Technical Comparison

Metric	R/50 Series	R/51 Series
Tube Ø	12.7–38.1 mm	15.9–38.1 mm
Exp. Depth	9.5–152.4 mm	28.6–171.5 mm
Roller Length	38.1 mm	57.1 mm

Expert Insight: Expansion in thick tubesheets requires superior depth control and uniform radial pressure. The R/50 and R/51 series' three-roller mechanism provides the balanced force necessary to prevent tube distortion while creating a reliable, leak-free seal across the entire thickness of the tubesheet.
