Standard-Metallwerke, Germany, is a
specialist in drawing precision and
premium tubes in aluminium, copper
and brass, with business units for
automotive, aerospace, HVAC/R,
industry and solar applications.
One of the company’s recent success
stories from intensive engineering work
is the S-Cooler, a wire-loop finned
cooler, which enables a perfect cooling
solution at 360° incident airflow.
Coaxial tubes as a tube-in-tube system
are another innovative development.
This solution allows a heat exchange
between two independent running
liquid media to be used in the field of
air conditioning and cooling devices,
including automotive applications.
Adapted to market requirements,
the company’s finned tubes feature
a maximum efficient heat exchange
solution. The individually adapted size
of ribs support high performance for
various applications.
Aluminium tubes are predominantly
used for these product applications,
due to the demand for lightweight
systems, and to support a high
requirement of stability.
The company’s PA12 coated S-Cot
tubes provide protection against
corrosion, insulation and mechanical
impact protection,making themsuitable
for use in severe environments. The
company has also developed a long-
life alloy based on a unique chemical
composition for drawn tubes. S-Life
is designed to provide high corrosion
resistance and outstanding SWAAT-
test results.

Heat exchanger tubes
Sandvik Materials Technology maintains an extensive manufacturing programme
for straight heat exchanger tubes to ensure availability on short lead times.
Based on popular sizes and material grades, the seamless heat exchanger
tube programme covers standard austenitic, duplex and high alloy austenitic
stainless steels in addition to titanium and zirconium.
Sandvik’s main size range, produced in imperial and metric dimensions, covers
19.05 to 25.4mm, in wall thicknesses from 1.65 to 2.11mm. Available grades
include 304L, 316L, 321, 316Ti, Sanicro 228, Sandvik SAF 2205 and Sandvik
SAF 2507. Standard straight length for heat exchanger tubes is 6m.
“Maintaining an ongoing manufacturing
programme for heat exchanger tubes
provides us with the ability to supply
customers on short lead times where
a small number of tubes are required,”
commented Phil Cherrie of Sandvik.
“These are often needed at short notice
for maintenance work or to carry out
repairs to existing heat exchangers
where plant downtime can be a
significant issue.”
The company offers a comprehensive
range of heat exchanger tubes sizes
and material grades, as part of its
extensive manufacturing programme,
to suit all types of applications from
sea water coolers to oil refineries and
from chemical to power generation
applications. In addition to straight heat
exchanger tubes Sandvik can supply
both straight and U-tubes as a project
package.
Other products in the Sandvik heat exchanger tube supply package include
standard stainless steel and special grade complementary products, welded
tubes, sheet and plate, tube fittings for butt welding and socket welding,
threaded joints and flanges.
