Condenser Tube Expanders/Heat exchanger Tube Expanders

Condenser Tube Expanders/Heat exchanger Tube Expanders enlarges the ends of copper, brass, and aluminum tubing so that another tube of same size may be inserted into expanded section and soldered for leak-resistant joint. Expanders are designed to leave 0.015 " clearance for slip fit. Average depth of expansion is 3/4 ". These Tube Expanders comes with several improvements in the design and manufacture of condenser tube expanders have been pioneered by Powermaster. The New Generation II series Condenser Tube Expanders / Heat Exchanger Tube Expanders will outlast any other manufacturers tube expanders. Optimal roll alignment for fast rolling. Maximum roll to tube contact reducing spring back effect. Equal load distribution leading to extended tube expanders life. CNC machined cages give Precision guiding to rolls during expansion.
One piece constructed mandrel on all models mates with well contoured rolls to give un-briged smooth expanded tube. State of the art cryogenic and heat treatment facility guarantees best grain structure in both pre-machined and finished forms. Dual purpose collars with reversible nose to expanders tubes flush with tube sheet and tubes projecting from tube sheet. Highest quality bearings eliminate heat due to friction. Double radius rolls for easy long reach step rolling, supplied standard on all models. Use of high end solid modeling design and finite element analysis software optimize results and eliminate design & assembly flaws.
