tube expanders for boilers and boiler  accessories

AB series - boiler tube expanders

Configuration:  three Parallel rollers with thrust bearing

Tube sizes covered: 7/8"OD up to 4.1/2"OD

The AB Series covers tube sheets from 1/2" to 2.5/8".

AB Series with fitted thrust bearing

features:

Thrust bearing reduces frictional build up for smooth expansion cycles.

Similar to the A Series for straight parallel expansion.

Use:

The AB Series is similar to the A Series expanders apart from being fitted with a thrust bearing which reduces frictional heat build up within the tool. This extends the life of the rollers and mandrel and allows the expander to be used for extended periods of time.

Consult the PDF Specifications below to cross refer all data to the tube OD, wall thickness and tube sheet thickness. Also, part numbers for spare mandrels and rollers can be found here. If the PDF is two pages then the data has to be read across the two pages.
