Copper Tube
58 Tube Products International January 2010
Industrial tube from Wolverine Tube,
Inc consists of small and medium-
diameter copper tube made to
customer specifications for equipment
manufacturing. Industrial tube products
include coils in lengths of up to one
mile (to permit economical transport
to customers for further processing),
smooth straight tube, internally-
enhanced tube with internal surface
ridges to increase heat transfer in
air conditioning coils, and very small
diameter capillary tube (as small as
0.01") for control valve operations.
Wolverine Tube’s smooth surface tube
components have helical integral ridges
that allow for efficient heat transfer.
These integral ridges improve the
efficiency of heat exchangers in which
refrigerant condenses or evaporates
within the tube. The smooth surface
tube products can be supplied in level
wound coils, or in straight lengths.
Inner grooved copper tubes are found
in residential and commercial air con-
ditioning and refrigeration applications.
The company’s seamless inner grooved
tube’s (IGT) highly precise dimension
and integral groove shape increases
the efficiency of heat exchangers,
continuously driving improvements in
environmentally friendly refrigerants.
Capilator© tube is Wolverine’s capillary
tube, used throughout the refrigeration
and air conditioning industry for flow
restriction applications. These tubular
components are produced in copper
hard drawn straight lengths. Control
Tube is a small bore annealed tube
used in applications such as heat loop
and pressure control for refrigeration
manufacturing. Control tube is available
in straight lengths, level wound coils
and bunch coils.
