Articles on Tube Expander:
Tube Expander is a tool used for expansion of tubes in tube sheet holes of boiler, heat exchanger, condenser, evaporator & other process equipments. Boiler Tube Expander. Tube Expansion gives leak proof joint between tube & tube sheet & it can sustain even at high pressure & temperature.
There are different type of tube expander based on type or shape of expansion & length of expansion required at end of tubes.
In boiler tube expander, there mainly 3 type of expanders are:
1. BA series tube expander: (3 plain roller) : for plain expansion.
2. BAF3 series tube expander (3 plain, 3 flare) : For Flare/Bellmouth expansion of tube
3. BCSB series tube expander : (3 or 5 plain roller) : for bottom end of tube sheet where space is either not available or very less. This expander is mainly used in bottom end of Sugar Mills PAN equipment.

Other tube expanders are:
4. B114 tube expander
5. B1000 series tube expander
6. B2000 series tube expander
7. BSB series tube expander
8. Combination of Beading Expander
Less no of tubes can be expanded manually by using tube expander with reversible ratchet wrench.
If no of tubes are more than 200 or 500 nos then it's advisable to use either electric tube expansion machine or hydraulic tube expansion machine.
To select tube expander, below details are required:
a. Tube OD (outside diameter)
b. Tube ID (inside Diameter)
c. Tube Sheet/drum thickness
d. Material of Tube
e. No of tubes to be expanded.
