A Q U AWA R M T H E O R I G I N A L
Benefits of Aquawarm’s
flexible pipes
The unique design of the Aquawarm system provides the maximum of
flexibility. All materials have been selected so as to simplify as far as possible
the handling, laying and installation of the pipes: the soft copper pipes, the
flexible glass wool insulation and the corrugated outer casing ensure that the
culvert pipe is very easy to bend.
The pipes are laid in a sinusoidal pattern, but the precision with which this
is done is not an absolutely critical factor. The system is so flexible that the
pipes can be laid with margins, if this proves necessary. When reality is not
straight as an arrow, then Aquawarm really does itself justice.
Single pipes with standard insulation,
OD 15 – 28 mm, are normally supplied in 25-m coils. All other single
pipes with an OD of up to and including
70 mm are supplied in 12-m lengths.
Sizes 88.9 and 108 mm are supplied
in 9-m lengths. All twin pipes are
supplied in 12-m lengths. Sizes up
to 2 x 22 mm can also be supplied
as 25-m coils.
Pipes of smaller sizes can be
delivered as straight lengths and
must therefore be bent into a
sinusoidal pattern at the site.
Aquawarm has its own design department, which is never further away
than a telephone call. Phone us
directly if you have any questions!
Aquawarm pipes are available in sizes
from OD 15 to 108 mm. You can obtain
them with standard or extra insulation.
Practical and widely used variants are
the twin pipes (dim Ø 2 x 15 – 2 x 54
mm) and twin pipes for domestic hot
water and hot water circulation (dim
Ø 22 + 15 – 70 + 35 mm).
Twin pipes of sizes 2 x 15, 2 x 18 and
2 x 22 mm are delivered in straight
lengths and must therefore be bent in
curves with an arc length of 2 m and
an arc height of 200 mm at the site.
The Aquawarm system is designed for
an operating temperature of up to 120
oC (250 oF) and an operating pressure
of 16 bar.
Simple to lay, simple to install
The materials used in Aquawarm
pipes are in themselves soft and flexible, which also makes the complete
system soft and flexible. The design
allows you to lay the pipes in the
most suitable way. For example, they
can be bent around stones and wells.
Aquawarm does not need any
special training or special equipment
for the laying of the pipes. A single
contractor can handle the complete
work.
Assistance from Aquawarm
Aquawarm is happy to provide
assistance in your planning work.
We are naturally also prepared to
participate, if necessary, in your
project, providing training and help
with the assembly, jointing and connection work.
Pliable pipes, broad range
Aquawarm has, of course, a complete range of pipe sizes, lengths,
different insulation thicknesses, twin
pipes, pipe fittings, joints, bends, etc.
The built-in flexibility of the
Aquawarm system in combination
with the laying of the pipes in a
sinusoidal pattern ensures that the
heat expansion is absorbed inside
the pipes. This simplifies the planning work, without it being necessary to calculate fixed-point restraints or expansion loops, as well as
installation without the need for any
preheating.
Plats för en bild
The flexible design ensures that not
only will movements be taken up
inside the culvert pipes, but also that
the pipes can be laid around stones,
trees and wells.

Expansion allowance/sinusoidal laying
Pipes of all sizes ≤ 42 mm can normally be bent to
90° at site. When pipes are bent with the radii listed
in Table 1, bending springs (length 2 m) must be
used. If tighter radii are required, use prefabricated
bends. If larger radii are required, the use of bending
springs is not necessary (see Table 2).
Amplitude (=arc height) 20 cm
Node
Node
Pipe bending on site
Node
The sinusoidal pattern of Aquawarm’s pipes absorbs
the expansion of the copper pipes, which ensures
that lateral movements occur instead of axial movements. The expansion of the copper pipes is distributed over the arcs, and the largest lateral movement
occurs at the middle of the arc.
The mechanical stresses are also largest at these
points. If possible, joints should be located in places
where the stresses are lowest, i.e., at the nodes.
Single pipes of sizes Ø 15-28 mm are normally
supplied in coils. The pipes must therefore first be
straightened and then bent into a sinusoidal pattern
at site. Twin pipes of sizes 15-22 mm are supplied
in straight lengths and coils. No special tools are
needed for the sinusoidal bending of pipes of sizes
Ø 15-28 mm. This can normally be done by hand,
since the copper pipe is soft annealed and the
outer casing is corrugated.
Single pipes of sizes ≥ 35 mm and twin pipes of sizes
≥ 28 mm are pre-bent into a sinusoidal pattern at
the factory and therefore only need to be laid in the
trench. Ready-bent Aquawarm pipes supplied from
the factory are shaped so that the joints will always
be located at the nodes. The pipes should be cut at
the nodes. In the case of the three largest sizes, 70108 mm, it is important that branches are located
at the node points. The larger the size of the pipes,
the greater will be the stresses (applies at the design
temperature 120 °C and the operating pressure
1.6 MPa).

Wall penetration
Care must be taken at wall penetration to ensure
that the moisture barrier at the outer wall is supplemented after the embedding. A rubber sealing ring
should be fitted over the outer casing end for a horizontal entry through a underground wall or a junction pit wall. The wall penetration with transition
pieces are already equipped with such a sealing ring
prior to shipment. Mount the sealing ring so that it
will be entirely cast in the concrete.
19
Penetration through a floor structure or foundation
slab in the vertical plane is best made by bending
the Aquawarm pipe to the desired radius (see Table
1 regarding the minimum radius) or by using prefabricated bends. When holes are made with a diamond
drill, the hole diameter should comply with Table 3.
Sizing and cleaning
Prior to the brazing, the copper pipe ends must be
carefully calibrated with a sizing tool in order to
ensure optimum capillary action. Then clean the
ends with Scotch Brite or the like.

Table 3
Exposing the pipe ends
The pipes are shipped with a short piece of the outer
casing projecting beyond the copper pipe ends as
transport protection. First expose the copper pipe
end (length 15 cm for PEH ≤ 128 mm and for PEH
≥ 163 mm). Then check that the pipe ends have not
been deformed and fit the shrink sleeve.
If the pipes have been cut, fit the cut end with a centering plug and end cap (inner seal). Shrink on the
end seal and shrink sleeve with a gentle propane gas
flame (see also under ”Joining of the outer casing”).
Cut pipes that are not immediately fitted with end
caps must be protected against moisture and dirt.
This can be done by using special rubber covers.
Brazing
Copper pipes are joined by means of capillary
brazing with hard solder. Capillary tube fittings are
normally used. The capillary action can also be
obtained by expanding one of the pipe ends, using
an expander tool. Prefabricated fittings should not be
expanded, since the copper pipe has not been
soft annealed. Hard brazing is carried out with an
overlap of the joint surface of at least three times
the thinnest wall thickness.
Use silver phosphorus copper brazing alloy, e.g.
AGA Fosco 715 or the like. This brazing alloy is
self-fluxing, which is very advantageous during the
installation work. Brazing alloy with at least 5%
silver is recommended for primary installations.
Brazing alloy with at least 2% silver is permissible
for secondary installations.
Use a brush nozzle to avoid overheating. A nozzle
with a capacity of 500 l/min is used for sizes 15-42
mm, 750 l/min for sizes 54-88.9 mm and 1000 l/min
for 108 mm.
Transition from copper pipe to steel pipe
Use a transition piece for the transition between
copper and steel pipes. Braze the copper end of the
transition piece to the Aquawarm pipe and weld the
bevelled steel end to the steel pipe.
20
Pressure-testing
Before applying pressure to the pipeline, the
completed pipework should be entirely filled with
water and properly vented. Fill the water slowly
and, if possible, from the lowest point of the
pipeline system.
The test-pressure must be at least 30% higher
than the normal working pressure.
If the edges of the sleeve have been damaged,
any notches etc must be cut away. When the sleeve
shrinks, the notch will otherwise grow and this may
lead to cracking of the sleeve.
When shrinking on the end caps (inner seals), first
heat the larger end as described above and then the
smaller one against the copper pipe.
Handling
Use a crane or other lifting device to unload and
lift the pipes, together with broad straps or strops
included in the delivery. Don’t use chains or wires.
A lifting beam is recommended to ensure a uniform
load along the entire pipe.
Individual pipes may be manually unloaded. The
pipe must then be lifted, not pulled, off the truck to
ensure that the outer casing is not damaged by sharp
edges.
Joining the outer casing of PEH
Storage
After approved pressure-testing, the copper pipe is insulated and joined with the PEH outer casing at all joints.
Place the pipes on a level surface without any sharp
objects. Use pieces of wood with a minimum width
of 6” as support to the extent that is necessary to
allow the removal of the lifting strops.
After removing any dirt from the outer casing, the
corrugated inner sleeve is cut to the right length and
slipped over the copper pipe. Then wrap tape around
the sleeve where it joins the casing in order to center
it.
Then remove the protective wrapping from the outer
shrink sleeve and centre the sleeve over the joint.
First, gently heat the entire sleeve with a propane
gas flame. Don’t use a welding torch.
Store pipe fittings with the copper pipe ends facing
downwards.
Other parts are normally shipped in cardboard
boxes, which should be stored in a place protected
against rain and snow.
Then start to shrink the sleeve in the centre and continue with this around the sleeve towards its ends. Keep
the propane gas flame moving all the time.
To avoid overheating of the outer casing, turn the
propane gas flame towards the middle of the shrink
sleeve before the complete shrinking process takes place.
When the shrinking process has finished, the shrink
sleeve should grip firmly against the corrugated outer
casing. The mastic on the inside of the sleeve should
seep out around the ends of the sleeve, and the outline of the joint should become visible. Check the
shrinkage by pressing the warm sleeve with the finger.
The fingerprint should disappear as soon as the finger
has been lifted off.
21
Brazing and shrinking
1. Strip both pipe ends.
2. Fit the shrink sleeve (leave the protective wrapping on the sleeve).
3. Calibrate the pipe ends. Use a wooden or plastic hammer.
5. Join together the copper pipes by means of brazing.
Use capillary pipe fittings or an expanding tool. Braze
with a brush nozzle and use a silver phosphorus copper
brazing alloy with 5% silver according to the standards,
e.g., AGA Fosco 715 or JMM Silfos-5, which are selffluxing.
4. Clean the pipe and pipe fittings, using Scotch Brite
or the like.
6. When this has been done, pressure-test the system
and inspect it before fitting the insulation and the outer
shrink sleeve.
7. Insulate the copper pipe by adjusting and fitting a corrugated inner sleeve.
22
8. Remove carefully any mud and dirt from the casing.
Fit the corrugated inner sleeve and secure with tape
where it joins the outer casing.
9. Remove the wrapping from the inside of the shrink sleeve
and slide the sleeve into position. Ensure that the outer-sleeve
is fitted in the centre of the joint.
10. Shrink the sleeve using a long, soft propane gas flame, which is
kept moving all the time. Take care not to damage the outer casing
(don’t use a welding torch). First lightly heat the entire sleeve. Then
shrink the sleeve from the middle. Begin from below. Then continue
along the sleeve to its ends. To avoid overheating of the outer casing,
turn the propane gas flame towards the middle of the shrink sleeve
before the complete shrinking process takes place.
11. When the shrinking procedure has been finished, the shrink sleeve should grip the
corrugated outer casing firmly. The mastic on the inside of the sleeve should have melted
and seep out around the ends of the sleeve. It should be possible to see the outline
of the joint. Press with a finger on the warm sleeve; the pressure mark should disappear
as soon as you have removed your finger. When the joint has cooled down, it will have
attained its full mechanical strength.
Cutting of pipes at site
If the pipes are cut at site, fit a centering plug and end cap on the bare pipe end. Shrink on the end cap with a gentle
propane gas flame in the same way as for the shrink sleeve (see above). N.B. First shrink the part of the end cap that
is intended to seal against the outer casing. Then shrink the end cap on to the copper pipe.

Aquawarm is the original among flexible
district heating and domestic hot water
pipe systems.
The system consists of soft copper
pipes insulated with freon-free (CFCfree) glass wool and then enclosed in
an outer casing of corrugated polyethylene.
Aquawarm pipes are laid in a sinusoidal pattern, which allows heat expansion of the copper pipes inside the
insulation, while the outer casing in the
ground does not move.
This makes the entire system flexible,
easy to install, reliable, environmentally
friendly and economical.
Why choose anything else than the
original?
