CNC Horizontal Tube Expander Machine HVAC Machine
1.Introduction
The tube expander machine is divided into the horizontal tube
expander and vertical tube expander type. The horizontalexpander
ideal applications are in the case of large tube lengths, even for
limited
production lots, and are characterized by the speed and ease of
programming
(for coils already performed it is only necessary to call up the
code).
The expansion of the tubes may be performed by pushing
(for straight tube heat exchangers) or pulling (for hairpin heat
exchangers);
in the latter case, the process guarantees the execution of tubes
of the
same length – eliminating all downstream trimming processes as the
remaining stick-out of the expanded is only determined by the cut
length
of the tubes, all due to an exact calculated, controlled shrink
rate.
Having the ability to combine different geometries, tube diameters
and
push or pull systems – this horizontal tube expander truly offers
the most
flexible expander on the market. Our industry knowledge and deep
engineering
has allowed our company be the top supplier for the horizontal
expander market.
