Boiler Tube Expander
Key things operators watch:
- Proper torque (over-rolling can crack tubes)
- Tube material vs tube sheet material
- Expansion length and wall thinning
- Whether seal welding is also required
We are the manufacturer of boiler tube expanders in india for the last 25 years catering to various industries and major boiler manufacturers in India and abroad.
Description
A boiler tube expander is a tool used to secure boiler tubes into tube sheets in boilers, heat exchangers, and condensers.
It expands the end of a tube so it tightly grips the tube sheet hole, creating a leak-proof and mechanically strong joint.
How it works:
- Insert the expander into the tube end
- Rollers inside the tool press outward as it’s rotated
- The tube plastically expands against the tube sheet
- Result: tight seal + structural hold
Common types:
- Manual tube expanders – hand-driven, small jobs
- Pneumatic expanders – faster, controlled torque
- Hydraulic expanders – high precision, heavy-duty boilers
- Combination expanders – rolling + beading in one tool
Where it’s used:
- Power plant boilers
- Marine boilers
- Heat exchangers
