Description :
Sapsons Hydraulic Tube Expansion Systems are industrial-grade tools manufactured by Sapsons Industrial Equipments Pvt. Ltd., designed for precise and reliable expansion of tubes into tube sheets in critical equipment like heat exchangers and boilers.
Product Description :
Sapsons hydraulic tube expansion systems use controlled hydraulic pressure to expand tubes radially, ensuring a tight, leak-proof, and mechanically strong joint between the tube and tube sheet—without welding or adhesives.
These systems are widely used in industries such as:
• Power generation
• Oil & gas
• Petrochemicals
• HVAC and refrigeration systems
Key Features :
• High precision expansion for consistent joint quality
• Leak-proof sealing ensuring long-term reliability
• Hydraulic pressure control for uniform force application
• Suitable for various tube materials (including stainless steel and thick-walled tubes)
• Durable construction for long service life
Components (Typical Sapsons System) :
• Hydraulic power pack (pressure generation unit)
• Expansion tool / expander head
• Hoses and connectors
• Control system (manual or automatic)
Working Principle :
1. The hydraulic expander is inserted into the tube.
2. Pressurized hydraulic fluid activates the expansion mechanism.
3. The tube expands outward into the tube sheet hole.
4. A permanent, tight mechanical bond is formed.
Advantages :
• Eliminates need for welding
• Reduces risk of tube damage
• Ensures uniform expansion across all tubes
• Improves efficiency and reduces rework
• Ideal for critical applications requiring leak-proof joints
Typical Applications :
• Heat exchangers
• Condensers
• Boilers
• Chillers
• Oil coolers
Summary :
Sapsons Hydraulic Tube Expansion Systems are engineered for precision, durability, and efficiency, making them a preferred choice for industries where tube joint integrity and leak prevention are critical.
