MAUS TUBE EXPANDER R141 & R161 Series
Description
Technical specification
Maus R/141 & R/161 Multiple‑Pass Tube Expanders
The MAUS TUBE EXPANDER R141 & R161 Series are multiple‑pass, three‑roller tube expanders engineered for deep and thick tubesheet applications.
Designed to expand tubes in thick tubesheets by repositioning the collar without removing the tool, they offer both efficiency and precision.
Key Features & Applications
Quick‑Release Thrust Collar
Both R/141 and R/161 models feature a unique click‑in collar which allows fast repositioning between passes.
This step‑by‑step expansion method ensures thorough expansion across the full sheet thickness without removing the expander.
Tube Diameter & Depth Ranges
-
-
- R/141: Compatible with Ø 15.9 – 25.4 mm (⅝″–1″) tubes; adjustable expansion depth from 25.4 mm up to 200 mm (1″–7 ⅞″)
- R/161: Tubes Ø 15.9 – 25.4 mm; depth adjustment from 44.5 mm to 225.4 mm (1 ¾″–8 ⅞″)—ideal for very thick sheets
-
Three‑Roller Balanced Design
The three‑roller configuration provides uniform radial pressure, ensuring consistent tube-to-tubesheet contact, minimizing distortion, and enhancing sealing integrity.
Industrial Applications
Widely used in boilers, heat exchangers, and condensers with thick tubesheets where single‑pass expansion would be inadequate.
The multiple‑pass incremental method ensures complete expansion and optimal sealing.
Ease of Use & Efficiency
Quick collar release significantly reduces manual adjustment time.
Works with pneumatic or electric torque-controlled drivers for controlled expansion in each pass.
