Tube introduction
Tube is generally thin wall 0.51 mm to 6 mm thick,
specified by the actual O.D. and W.T. but may be
specified by any two of OD, I.D. or W.T. Tube is
produced as either seamless (hot finished or cold
finished), or welded.
The term “tube” is also applied to non-cylindrical
sections, i.e., square (SHS) or rectangular tubing (RHS)
and oval - outside dimensions denoted by width and
breadth (or height). Tolerances are generally tighter
than both hollow bar and pipe depending on applicable
product specification.
The tube O.D. (or width/breadth) is constant,
irrespective of W.T.
The I.D. of a tube will depend on the W.T. of the tube.
The W.T. remains as specified regardless of the O.D.
as a nominated thickness, or commonly a specific
“wire gauge”, e.g. 16 swg = 1.63 mm av according to
International Standard Wire Gauge, or 16 bwg = 1.65
mm av according to Birmingham Wire Gauge tables.
If in doubt, always specify at least 2 dimensions
required - O.D. , W.T. or I.D. to ensure correct supply.

Ovality
Ovality is the difference between max. and min. O.D. measured at
any one cross section. The average of the max and min O.D. readings
should be within the O.D. tolerances. Over 127.0 mm O.D. with
wall thickness ≤ 3 % of O.D., ovality tol. is max.1.5 % of O.D.

Make the right choice
chemical compositions tailored to specific applications,
customers, markets or country requirements.
Compared to a complete plant, the cost of
a heat exchanger is relatively low. However,
reliability can have a significant impact on
operating costs.
Our tubes are suitable for all types of heat exchangers:
coolers, condensers, evaporators, preheaters, reheaters,
reboilers, steam generators and air coolers.
For this reason, it’s vital that fabricators and end users
have access to seamless tubes developed and produced
for specific service conditions. This requires that
suppliers provide a range of tube grades and flexibility
in production processes that meet specific requirements.
That’s why many choose Sandvik stainless steel
tubes. Our extensive experience in the production of
special stainless steels and tubes, our flexibility in raw
material sourcing, our willingness and ability to find
materials solutions result in special steel grades with
Extreme conditions can be handled by developing
competitive and innovative solutions through close
cooperation with our customers. Together, we can
achieve lower operating costs and increase long-term
operating reliability.
Sandvik’s assets are many: Product delivery and
advanced communication systems. Strategic production
locations worldwide. Sophisticated plant programming
capabilities that ensure reliable and efficient product
supply. Advanced logistics that provide global
distribution.
A wide range of complementary products
The Sandvik heat exchanger tubes supply
package includes standard stainless steel
and special grade complementary
products. These are: welded tubes,
sheet and plate, tube fittings for
butt welding and socket
welding, threaded joints
and flanges.

Grades, standards and size range
Sandvik has an extensive manufacturing program for
seamless heat exchanger tubes covering most types of
standard austenitic, duplex (austenitic-ferritic) and high
alloy austenitic stainless steels as well as titanium and
zirconium.
Our main size range, produced in imperial and metric
dimensions ranges from 12 mm up to 40 mm outside
diameter. Special sizes can be made to order. Tubes
are supplied in straight lengths up to 30 meters, or
as U-bends. In the table below, you can find the most
common standards and grades for heat exchangers.

Tube
Titanium and zirconium tubing
Ex. mill stock or production
In environments where not even the best stainless steels meet the corrosion resistance
requirements, titanium and zirconium can be used.
The manufacture of seamless titanium and zirconium
heat exchanger tubes at Sandviken, Sweden, is carried
out through a completely integrated process. It
starts with melting of raw materials in high vacuum
furnaces and ends with the finished seamless tubes. The
manufacturing process is specially designed to work
with non-ferrous metals like titanium and zirconium.
The Sandvik group has been the world’s largest
independent manufacturer of seamless zirconium and
titanium tubing for over 40 years, supplying to a wide
range of industries including chemical, petrochemical,
aerospace and nuclear.
Titanium
Titanium has a unique set of properties that makes
it suitable for a variety of applications. It has a high
environmental resistance, relying primarily on a very
thin, tenacious and highly protective surface oxide film.
Titanium is highly resistant to wet chlorine
chemicals, practically all salt solutions,
seawater, a range of acids, organic and
inorganic chemicals and gases. The same
oxide film provides a high resistance
to erosion in high velocity process
streams. The corrosion and erosion
resistance makes titanium a
preferred heat transfer material
for shell/tube heat exchangers,
since it permits the use of thin
heat transfer walls and high fluid
flow rates. In addition, titanium
has only half the weight of steel. It is non-magnetic and
is characterized by a high melting point, high strengthto-weight ratio and a low modulus of elasticity.
Available Sandvik ASTM/ASME defined grades:
1, 2, 3, 4, 9, 11, 12, 16, 17, 26, 28.
Other grades can be offered on request.
•
The range of dimensions cover outside diameters from 8
mm up to 40 mm and 16 meters with certain OD/L and
OD/Wt limitations
•
All tubing can be supplied as straight lengths or as
U-tubes.
•
Non-destructive testing facilities include ultrasonic testing,
Eddy Current testing and hydropressure testing.
•
Tubes are normally supplied as cold pilgered, vacuum
annealed and cleaned with the OD in the as polished
condition.
Zirconium
Zirconium is highly resistant to a wide range of acids
and bases, both organic and inorganic, which makes
it an interesting and exceptional long life alternative
to other materials in highly demanding applications.
The seamless tube zirconium grade, produced for heat
exchanger applications, is Sandvik Zirconium 702*,
which offers the process industry a high quality and
competitive product concept.
* As per ASTM/ASME B, SB523 or equivalent.

U-bent tubes for heat exchangers
Ex. mill production
Sandvik is one of the world’s leading suppliers of U-bent tubes. U-bends are manufactured from
Sandvik precision straight tubes and are produced by the cold-pilgering method with a bright
annealed surface. Production is strictly controlled, step-by-step, in order to fulfill all the technical
demands from our customers.

and the tubes are internally cleaned with air.
• Furnace is computer controlled and all data is recorded.
• Before packing, both ends are capped with plastic caps.
• We use an argon protective atmosphere inside the tubes.
Packing
• We can provide all types of annealing: solution, stress relieving or
stabilization
• In strong, open or closed, wooden boxes depending on destination - max. 8,000 kg.
Technical parameters
• Ends of tubes protected by plastic caps.

Bending radii from 1.5xOD up to 1250 mm. Minimum bending radii for
OD´s over 28 mm after agreement.
Leg length min. 1,000 mm
• Vertical separators for each radius.
• Chloride free plastic separators between each row, every 2 meters.
• Each bundle is covered with plastic.
• Customers can provide a packing drawing or Sandvik can prepare
a packing plan.
Leg length max. 12,000 mm
Heat treatment for radii up to 1,000 mm
• Packing lists, covered with plastic, are placed on each wooden
box for easy identification of order details – including exact list of

Tube
Cold bending
Wall thinning and minimum bending radius
Seamless hydraulic tube and the minimum radius permitted for these tubes.
Calculation of reduction in wall thickness due to bending to be considered along with bursting pressure.
Cold bending - wall thinning and minimum radius
Different techniques do exist and the results may vary depending on the method used.
The reduction of wall thickness can be estimated by the following formula:
tmin =
tt + 2R
2R + OD)
Where…
tmin is the thinnest wall in the bent section
tt is the thinnest tube thickness allowed according to tolerances
R is the radius
OD is outer diameter
The smallest possible bending radius to avoid the risk for cracking can be estimated by following formula:
Rmin = OD x 100
2 x A5
Where A5 is the minimum elongation value.
Austenitic stainless steel often has a minimum value of 35-45%, while duplex (ferritic austentic) is often a
minimum 25% and ferritic stainless steel is often down to minimum 15%.
Cold bending without a mandrel allows the tube section to become oval, which often means a smaller radius can
be bent than that which the formula indicates. A tight radius increases the ovality, which in turn reduces the crosssection. That results in an increased pressure drop, which may affect the process.
