Copper condenser tubes
With over 40 years’ experience, and a
history going back over 75 years, AMI
Dutchmetals based in Apeldoorn, The
Netherlands, is a European supplier of
condenser tubes in copper and copper
nickel alloys.
AMI Dutchmetals, in conjunction with
several Asian tube manufacturers, has
implemented quality systems to ensure
that only the best quality tubes are
produced.
The company has formed a partnership
with Huayu Non-Ferrous Metal Industries
of Zhangjiagang, China, a medium-
sized, privately owned manufacturer
that specialises in producing titanium
tubes. Huayu also produces seamless
and welded titanium tubes, as well as
pure nickel and nickel alloy seamless
tubes, following the introduction and
commissioning of new production
lines last year. AMI Dutchmetals is the
exclusive European representative for
all Huayu Non-Ferrous Metal Industries
tube products.
The mill benefits from full TUV
certification, possessing ISO 9001,
ISO 14001 and PED accreditation. In
addition to dedicated production and
QAC staff, the mill has an extensive
maintenance team. The company
welcomes independent third-party
inspections, which are carried out on a
regular basis by all known classification
institutions.

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
Qaem Copper Industries Company,
a producer of seamless copper
tube including LWC (plain and inner
grooved), straight and pancake, has
developed thin-walled copper tubes.
These thin-walled tubes are produced
in LWC form, both in plain and inner
grooved type.
The tubes are lightweight and have good
heat transfer compared to thicker-walled
tubes. The copper tubes are clean,
since they are annealed in a furnace
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.
that has been equipped with a copper
tube purging (CTP) system. This system
provides a protective atmosphere
through level-wound copper tube coils
during the annealing process.
To ensure product quality in the
domestic and foreign market, the
company’s test facilities have been
equipped with modern equipment
such as German eddy current testing,
German optical emission spectrometer,
English tensile tester and Japanese
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.
