Tube Expander Tools
Tube expanding is the art of cold-working the ends of tubes into intimate contact with the metal of the containing tube holes to form a leakproof mechanical seal and/or joint. In other words, it is a mechanical method of establishing a mechanical joint between a tube and a tube hole. While there are various types of tube expanders, they all share the common components of mandrels, rolls, and cages.
At Equipment Group International, we supply superior-quality tube expander tools from Airetool and Krais, including condensed heat exchanger expanders, boiler expanders, furnace expanders, and many special application expanders designed for ultimate reliability and performance.

Tube Expanders at EGI
At EGI, we maintain an extensive inventory of high-performance expanders. Our selection includes a range of styles and tube-expanding capabilities from Airetool and Krais designed for condensers, boilers, and specialized applications.Components in Tube Expanders
While each style of tube expander is manufactured for specific applications, all tube expanders consist of a mandrel, roll, and cage:- Mandrel: A tapered pin through the center of the expander to which the power is attached and, when advanced, pushes the rolls against the tubes.
- Rolls: A set of (3 or more) tapered cylindrical parts that are driven by a mandrel and contact the tube wall to be expanded. The taper on the rolls is in the reverse direction and one-half the taper of the mandrel if it is a parallel roll expander.
- Cage: This is the expander body (or housing) that holds the mandrel and rolls in place. The slots that contain the rolls also provide a feed angle that helps pull the mandrel in to provide expansion of the rolls.
Condenser Tube Expanders
Condenser tube expanders are engineered to provide precise and uniform expansions for heat exchangers and condensers. These expanders create leakproof seals that improve the performance and longevity of your equipment, even under extreme conditions. Our selection of condenser tube expanders include:- 900 and 1300 Series Expanders: Built for heavy-duty performance, the 900 and 1300 Series expanders excel in high-pressure environments.
- 800 and 1200 Series Expanders: The 800 and 1200 Series expanders feature a versatile design that delivers precise results in a variety of condenser configurations. Ideal for medium-duty applications.
- Specialty Expanders: We offer specialty expanders designed for unique or custom applications. Able to cater to specialized requirements.
Boiler Tube Expanders
Boiler tube expanders are built to withstand the high-pressure and high-temperature environments in industrial boiler systems. These expanders create robust tube-to-tube sheet connections for superior efficiency. Our selection of boiler tube expanders includes:- Straight Roll Expanders: Our Firetube Boiler Tube Expanders are designed for straight tubes, creating a uniform roll and a tight seal to prevent leaks.
- Flare Roll Expanders: Our Firetube Flare-Roll Series expanders are engineered for flaring and rolling tubes simultaneously. They are ideal for enhanced sealing and a professional finish.
- Specialty Boiler Expanders: We custom-design boiler expanders to meet specific boiler tube requirements.
