— Suncenter, a leading innovator in industrial manufacturing solutions, has unveiled its cutting-edge Electro-Hydraulic Tube Expander, a specialized hydraulic expansion device designed to revolutionize tube-to-tube sheet joining in critical equipment such as heat exchangers, condensers, high-pressure heaters, steam turbines, and boilers. This state-of-the-art equipment ensures uniform tube expansion through high-pressure hydraulic oil, enhancing reliability and performance in industrial applications.

Key Features and Advantages

1. Wide Compatibility: Capable of full-thickness, single-pass uniform expansion for tube sheets ranging from 15mm to 500mm, ensuring consistent results across diverse applications.

2. Precision Control: Digitally automated operation allows precise pressure settings via an intuitive interface, guaranteeing repeatable and reliable expansion quality.

3. Leak-Free Hydraulics: An integrated hydraulic system eliminates oil leakage, reducing maintenance needs and environmental impact.

4. Versatile Tube Handling: Compatible with internally threaded tubes, seamed welded tubes, and tubes with significant dimensional tolerances. On-site adjustments to mandrel diameter accommodate imperfect tube bores.

5. Corrosion Resistance: Low residual stress in expanded tubes minimizes risks of crevice and stress corrosion, extending equipment lifespan.

6. Noise Reduction: Post-expansion axial contraction of heat exchange tubes lowers operational noise levels in industrial settings.

7. Material Flexibility: Supports expansion of copper, carbon steel, stainless steel, duplex steel, titanium alloys, and composite materials.

8. Clean and Efficient: Non-polluting expansion process ensures compatibility with post-expansion welding requirements.

Enhanced Productivity and Durability

- Lightweight Design: The ergonomic handheld unit weighs just 1.5kg, enabling single-operator use and rapid, continuous expansion.

- High-Pressure Reliability: Imported fatigue-resistant rubber expansion sleeves withstand extreme pressures, averaging 100+ cycles per sleeve.

- Quick-Change Components: A unified mandrel design simplifies replacement of wear-prone parts, minimizing downtime.

- Unmatched Efficiency: Each unit can expand 2,000+ tube holes per shift, drastically reducing labor intensity while boosting output.
