Elliott’s 900 Series Flaring Boiler Expanders are self-feeding, specifically made for use in superheaters in watertube boilers or evaporator tubes. In only one operation, these expanders roll tubes parallel and flare projecting tube ends at 15 degrees from the tool center line.
Tube Size: 0.620” to 1.500” (15.4 – 38.1mm) OD
Roll Type: Flaring
Application: Superheaters, watertube boilers, and evaporator tubes.
Elliott’s 1500 Series Flaring Boiler Expanders are self-feeding, specifically made for use in Firetube and watertube boilers. In only one operation, these expanders roll tubes parallel and flare projecting tube ends at 20 degrees from the tool center line.
Elliott’s 3400 Series Flaring Boiler Expanders are the recommended tube expanders for expanding and flaring tubes in Firetube and watertube boilers. The prong style collar allows for uniform flare lengths as well as torque controlled tube rolling to obtain uniform expanded joints.
Elliott’s 3300 Series Straight Boiler Expanders are the preferred tube expanders for expanding tubes in Firetube boilers or in self-contained steam boiler units. They are recommended for any requirement for parallel expansion of tubes in tube sheets.
Elliott’s Collet Style Support Sheet Expanders are used with a handheld short stroke hydraulic ram and lightweight, low-pressure hydraulic pump to support sheet expand finned or prime surface tubes commonly found in chillers.
There are two motor power sources that are used for expanding tubes mechanically: electric rolling motors and pneumatic rolling motors. Determining what motor to use for a job will depend on operator preference, availability of electricity or air, and the application.
