The advantages o the XPress System
1 The XPress System
VSH Fittings continuously strives to be a leading orce within the
plumbing and heating industry and thereore provides the optimal
level o support to installers throughout the industry. An excellent
example o this is the XPress product range, which is comprised o
three pipe systems: stainless steel press ttings and tubes, carbon
steel press ttings and tubes (with and without a polypropylene
coating) and copper press ttings. All these ttings are manuacturedto incorporate the M prole.
XPress System products are manuactured using unique and modern
machinery. A completely automated actory guarantees high quality
and sae products. All welded products undergo a leak test which
avoids any problems with installation procedures at a later date.
The concept o the XPress system is to oer a complete solution to
installers and with the added advantage o oering a greater level o
fexibility overall. The XPress System consists o ttings, tools andtubes and under circumstances it is possible to utilise tubes rom
other manuacturers*. Furthermore the Xpress ttings can be used in
conjunction with various brands o press tools**.
The XPress System oers a comprehensive and high quality range o
ttings, with the added benet o an unusual level o fexibility when
selecting material and tools.

Advantages o the improved
M-prole: TheO-ringbeadispressed
perpendicularly into the tube.This results in a seamlesstransition between tting andtube which prevents dust or dirtrom entering into the O-ringbead o the tting.
TheO-ringbeadcreatesan
extra mechanical connectionbetween tting and tube.
Whenpressedpressureis
applied to the O-ring bead romthree angles which results in anextremely secure connectionand a strong deormation o theO-ring bead.
Duetothepositioningofthe
O-ring at the beginning o thetting the O-ring is highly visibleto the installer. This results ina saer installation process asany damage or misplacement isimmediately recognisable.
Advantages o XPress
Oneofthemostimportant
advantages o the XPressSystem, is the connection opipeline components withoutusing a heat source. As aresult o this there is no needor expensive insurancepolicies. The danger o redamage is also excluded.
Comparedwithothercold
connection techniques, theuse o XPress dispenses theneed or complicatedclamping techniques, longpreparation and drying timeswhich all lead to longerinstallation times.
Thequalityoftheconnection
is determined by the tool andnot the operator. Thisguarantees constant qualityand the connection can bevisually checked.
Thesimpleandfast
connection technology andthe short preparation time orthe tube result in urther cost
savings. As the connection isonly realized with the use opress tools, the need topurchase and store othermaterials such as gases,adhesives, threadingmachines, etc. becomessuperfuous.
XPress pressttings have theollowing technical advantages: Excellentowpropertiesdue
to laser-welded ttings. Nochancesofleakagedueto

2.2.1 XPress Stainless steel tubes
The XPress stainless steel tubes are thin-walled precision steel
tubes. The outer and inner suraces o the tubes are blank, ree o
discoloration and are supplied ree o manuacturing residue that
could otherwise cause corrosion. Entry o dirt during transportation or
storage is prevented by caps at both ends o the tube and utilising the
correct packaging or distribution.
This chapter gives you all technical parameters, predominantly applying
to construction technicalities o the XPress stainless steel tubes.
Heat insulation
The ollowing regulations apply to the insulation o potable water
tubing systems:
- Cold water lines should be protected against the occurrence o
condensed water and overheating in accordance with DIN 1988,
Part 2. For installations in the Netherlands the VEWIN work sheets
should be ollowed.
- Hot water lines should be insulated to prevent heat loss in
accordance with the Energy Conservation Law (EnEG) and the
Heating Installation Decree (HeizAnIV) (Germany). For installations in
the Netherlands the VEWIN work sheets should be ollowed.
The soluble chloride content in the insulation materials used should
not exceed 0,05% by weight in accordance with DIN 1988, Part 7.
Important: AS-quality insulation materials (compare also AGI Q 135)
contain signicantly less chlorides than the maximum allowable
content.

2.2.2 XPress carbon steel tubes
XPress carbon steel tubes are thin-walled precision tubes. The
XPress carbon steel tubes are protected against external corrosion
by a coating o zinc-plating and passivating chrome. The zinc layer is
applied thermally which results in a good adhesion between the zinc
layer and the tubes.
The XPress carbon steel tubes or sprinkler applications are maderom cold rolled steel which is galvanized using the Sendzimir
process. This chapter gives you all technical parameters, predominantly
applying to construction technicalities, o the XPress carbon steel
tubes.
Heat insulation
The ollowing regulations apply to the insulation o XPress carbon
steel tubing systems:
- Cold water lines should be protected against the occurrence o
condensed water and overheating in accordance with DIN 1988,
Part 2.
- Hot water lines should be insulated to prevent heat loss in
accordance with the Energy Conservation Law (EnEG) and the
Heating Installation Decree (HeizAnIV) (Germany).
Fire characteristics
XPress carbon steel tubes are considered as non-combustible tubes
according to German class A building materials DIN 4102 Part 1.
XPress carbon steel tubes with polypropylene coating are consideredas combustible tubes according to German class B2 building
materials DIN 4102 Part 1 i.e. burning without causing drops.
Metallic tubes with a synthetic coating up to 2 mm are considered a
non-fammable product in accordance with German building
regulations.

Threaded transition tt ings o red brass (gun metal)
Threaded transition ttings are generally manuactured rom red
brass. Here, distinction is made between strand casting (straight
part) and mould casting (bends, T-pieces and wall plates). Tests have
shown that press ttings o mould castings (sand castings) are less
suitable or gas installations or the ollowing reasons: mould casting
joints can never be as leakproo (homogenous) as with strand casting
or copper. There is always a danger o cavities (air locks that occurwhen pouring) despite 100% impermeability testing. The mechanical
load o the pressing heightens these dangers additionally as they can
open the cavities. Thereore, or saety reasons, we have decided not
to include any mould casting parts in copper gas press ttings.

XPress Leak Before Pressed function
XPress carbon steel, XPress stainless steel and XPress copper are deliv-
ered with a Leak Beore Pressed unction (LBP). Fittings with a Leak Be-
ore Pressed unction have the advantage that non pressed connections
will leak water during pressure testing. This means an incomplete press
connection is easily identied. As a result o this, the unction o the LBP
press tting system gives an irreutable result. Naturally, when mounted
correctly, the press ttings will be water- and air tight when pressed.
The LBP unction on XPress carbon and stainless steel in the
dimensions 12-54 mm is incooperated in the EPDM and Viton FPM
O-rings.

XPress copper with LBP unction
The mechanical properties o copper dier rom carbon steel and
stainless steel. Copper is a soter material which makes it possible to
create a LBP unction in the material itsel (O-ring bead) instead o the
O-ring. The LBP unction on the XPress copper is created by a triangle
shaped O-ring bead which will leak beore pressing. The unction o this
design is the same as the unction o the LBP O-ring or carbon and
stainless steel, which is to localize any orgotten pressings and preventmistakes with installation procedures.
Working principle o the XPress copper LBP uction
The triangle shaped O-ring bead will leave space between the tube and
the tting at 3 points in the O-ring bead. Through these gaps water will
fow when the tting is not pressed. The advantage with this design is
that there is still enough contact between the tube and the O-ring which
assures that the tube will stay in its place when inserted.
When pressed the shape o the O-ring bead will change and becomesround again (due to the mechanical properties o copper it is very easy
to reorm the bead rom a triangle shape to a perect round shape
again).
Ater pressing this results in a water- and
air-tight connection.
Working principle o the XPress LBP O-ring or carbon and
stainless steel
The design o the XPress LBP O-ring is based upon the creation o
a leak path within the O-ring itsel. This is made possible by adding
material to the O-ring and not taking any material out. This results in an
exceptionally strong O-ring without any weaknesses.
At strategic points small
grooves have been created on the
surace o the O-ring by adding
additional material. This means
there is a slight rise in the surace
o the O-ring and thereore water will fow through these grooves when
the tting is not pressed. When the pressure is increased this will result
in an escalation in the leakage. When pressed the O-ring is deormed
and as a result the rubber rom the raised suraces lls the grooves. This
creates a ully water- and air-tight connection.
Advantages
Easy to recognize non pressed
connections because oguaranteed water leakage duringpressure test
Extra saety because leakagedue to non pressing,(installation) mistakes areprevented
Ater pressing the ttings areguaranteed water and airtight
Extra material or leak unctionresults in a strong O-ring

guaranteed not to permanently exceed 60C. For thermal disinection
or example, short-term temperatures (max. 1 hour a day) o 70C are
permitted. Due to impermissible pressure increase as a result o heating
in sealed tubes it is not allowed to heat sealed o tubes.
2.3 .5 Equipotential bonding in houses
All metallic pipework systems using equipotent ial bonding must complywith equipotential bonding requirements. Ater all plumbing has been
completed, always ensure continuity checks are conducted by a
qualied electrician in accordance with the regulations. XPress stainless
steel and blank copper tubes according to EN 1057/R250-R290 in
combination with the respective ttings are electrical conductive tube
systems and thereore must be included in the equipotential bonding.
XPress carbon steel with and without polypropylene coating is not an
electrical conductive system and does not need to be included in the
equipotential bonding.
2.4 Press toolsPress tools consist o a press machine and the corresponding press
jaws- or slings. The press machine can be either bat tery- or
electrically powered. Figure 1 shows a battery powered version. For
each tube diameter used, the respective press jaws- and slings
should be used or a perect tight connection. Figure 3 shows a
section o the press prole beore and ater pressing.
All XPress ttings with a diameter
rom 12 mm to 108 mm can be
pressed using the suitable press
machines listed in the product range.
The respective jaws or slings with
M-profle should be used according to the diameter that has to be
installed. For diameters o 35 to 108 mms there is a possibility, that in
addition to the press sling, a special adaptor may also be required.
Note: GAS press fttings may only be pressed with the press jaws/
slings stated in the certifcate and the table. This also appl ies or
sprinkler installations.
VSH guarantees an excellent press connection,
provided the tools are used correctly. The tools

2.4.6 Maintenance and correct usage o press tools
Correct pressing with the XPress systems will be guaranteed when
the press tools stated in the tables 15-19 are used correctly. Regular
maintenance and lubrication o the press jaws, slings and tools is
necessary. Please observe the manuacturers instructions or use
and maintenance.
When jointing XPress copper & XPress copper GAS ttings in sizes
above 35 mm, it is essential that the grooves in the press jaw/sling
are lubricated with Dri-slide lubricant! The jaws/slings should be
lubricated in this way ater every 50 joints or sizes 42 mm to 76 mm
and ater every 5 joints or size 108 mm. Care should be taken to avoid
contact between lubricant and O-rings.
Badly maintained and/or damaged pressjaws are a potential risk.
Damaged jaws can damage the ttings, leaving metal particles behind
in the jaw as a result. I the same jaw is then used to press a stainlesssteel tting, these metal particles will be pressed into the tting, which
could lead to pitting and urther corrosion. Thereore always make
sure to properly clean your press jaws and slings when switching
between materials. Other press tools not mentioned in the chapters
2.4.1 up to 2.4.5 can be approved on request.

2.5 Installation guidelines
2.5.1 Cut the tube to length
Ater measuring, the tubes can be cut to length using a tube cutter
(see g. 4), a ne-toothed handsaw or a
mechanical saw with electrical motor suitable
or the tube material. The tube should always
be cut completely. Never partially cut thetube and break it o as this could cause
corrosion.
Do not use oil cooled saws, abrasive
wheels or fame cutting
XPress carbon steel tubes with polypropylene coating and
coated copper tubes (Wicu)
To ensure a sae connection o the press tting, it is essential to
remove the tubes synthetic coat up to the insertion depth beoreassembling the press tting using a jacket stripping unit. With
Wicu tubes the rigidity o the press connection is only achieved by
maintaining the insertion depth and by using an insert stiener.
2.5.2 Deburring the tube
The tube ends must be careully deburred
inside and out ater being cut to length. This
is in order to avoid damage to the O-ring
when inserting the tube into the presstting.
Deburring the inside o tubes prevents pitting
and corrosion. Deburring in- and outside
can either be carried out using a hand
deburrer suitable or the material or an
electrical tube deburrer. Burrs
sticking to the tube must be removed.
Figure 4: Cutting the tube
Figure 5: Deburring the tube
2.5.3 Calibration
Always ensure the tube ends are radial and even rounded. Especially
with white copper tubes according to DIN EN 1057/R220 (1mm), e.g.
Wicu tubes, the tube ends must be calibrated beore pressing.
2.5.4 Marking insertion depth
The necessary insertion depth (see table 21)
must be marked on the tube or the presstting (the latter or ttings with tube ends) in
order to guarantee a sae and proper joint.
Mark the insertion depth with a suitable
insertion depth marker as supplied by VSH.
Reliable pressing with the corresponding
tensile strengths can only be achieved by a
proper installation. The pressing operation
behind the bead is o crucial importance or
the tensile strength. The marking on the tube
must remain visible (but close to the tting)ater the connection is pressed to identiy any
movement beore or ater pressing.
2.5.6 Check the ftting and tube
Beore assembly, the tting must be checked
to ensure the correct position and presence o
the O-rings. The tube, tting and O-ring
should be examined or oreign material (e.g.
dirt, burrs), which should be removed i
present.
2.5.7 Assembly o ftting and tube
Insert the tube into the press tting up to the
marked insertion depth while being rotated
slightly and pushed in an axial direction at the
same time.

The marking or the insertion depth must still be visible. In case o ttings
without a stop the ttings should be inserted at least as ar as the marked
insertion depth. Rough and careless insertion o the tube into the press
tting may result in damage to the O-ring and is thereore not permitted.
When assembly is more dicult due to permitted tolerances in sizes, a
lubricant as water or soap may be used.
Under no circumstances may oils, fats or grease be used as lubricants.
To optimise the installation time, it is normal practice to assemble a
number o connections rst and, then press the various tube connections
one ater the other. Marking the distance (A) provides a check that the
tube has not been pushed out o the tting during the pressing process.
Beore starting the nal pressing process o
the various tube connections, it is also
important to check some o the minimum
required work space distances (see table 20).
Table 21 shown below gives the minimum required working space
so that the pressing o the ttings can be carried out correctly using
the appropriate press tools. These distances relate to the general
installation congurations that are schematically depicted in
gures 9-11.

Local regulations should always be observed.
Note:1. Gas tubes and ttings should be marked yellow to avoid conusion.2. Tubes are to be protected against mechanical damage when
mounted above screed.3. Carry out tests according to G1 Gas Guidelines (e.g. check covered
tubes).4. When mounted under screed (above the reinorcement) place in
concrete slots.
2.5.9 Bending
It may be necessary to bend a tube in order to carry out the
installation. Normal hand-, hydraulic or electrically-operated bending
tools with the corresponding bending ormers o tools can be used
or this. The manuacturer will determine the suitability o the bending
tool. XPress stainless steel, carbon steel tubes and copper tubes
according to DIN EN 1057 are cold pliable.
The tube may not be bent when warm due to the danger ocorrosion.
The minimum bend radius is as ollows:
Stainless steel tube (15-28 mm) rmin = 3,5 x d
Copper tubes (12-54 mm) according to rmin = 3,5 x d
EN 1057 and DVGW-GW 392
Carbon steel tubes (12-28 mm) rmin = 3,5 x d
A smaller bend radius is not permitted.
2.5.8 Pressing
Beore starting to press, the press jaws and slings must be checked or
dirt, which must be removed i present. Furthermore, it must be ensured
that the press machine is in good condition and that the instructions or
operating the device, maintenance and the manuacturers instructions
have been ollowed. Also make sure that you use the correct press jaws
and slings or the application and that these are corresponding to the
ttings which are used. In order to create a proper pressed connection,the groove o the press tool must enclose the press tting O-ring bead.
Once the pressing has started, always complete the press cycle and
under no circumstances interrupt the process. The approved
machines, press jaws and press slings are shown on pages 40 - 43 or
canbefoundlistedinthedocumentXPresstoolschedule,whichis
available on our internet site www.vsh-ttings.com at products >
press ttings > tool schedule.
Pressing gas installations
XPress stainless steel GAS and XPress copper GAS are suitable orgases o the second and the third gas amily (natural- and liquid
gases) according to DVGW Worksheet G 260 and are installed within
buildings (with HTC) and outside buildings (without HTC) as above.
A mixture o XPress stainless steel GAS and XPress copper GAS is
not permitted or new installations. Connections to gas ttings and
gas parts o brass, red bronze, ductile grey cast iron and aluminium
diecasting can be installed with gas threads/press ttings or fanges.
In case o repairs, make sure the tubes correspond with the DIN-EN/
DVGW standards, have a perect and undamaged outer surace and
have not been painted.

2.5.10 Mixed metal system
XPress stainless steel ttings and tubes can easily be combined with
controls and ttings o stainless steel and non-errous metals.
Connection with galvanized carbon steel or less noble ttings or
components can lead to contact corrosion. This can be prevented
using synthetic or non-errous metal ttings or spacers o at least 50
mm long (DIN 1988, part 7). For more inormation on corrosion, see
2.8, page 76. Table 22 shows the possible mix combinations.
We recommend using red bronze or brass ttings or the transition
rom copper to steel. Combinations should be avoided in the case o
gasinstallations(see2.5.8Pressinggasinstallations).
2.6 General application guidelines
2.6.1 Heat expansion compensation
The level o thermal expansion within tubing systems depends on the
type o materials used. This linear expansion needs to be taken into
account during the installation. This can be done by allowing or
sucient expansion space. Small length changes can be
accommodated by an adequate space or expansion as well as by theelastic properties o the tubing system itsel. Larger length changes
require compensation by other means; e.g. installation o expansion
compensation devices or placement o clips and
saddles.
Expansion compensators which can be used
are by pipe leg (gure 12), U-bend (gure 14)
or compensators.
The compensation size can be determinedbeorehand by calculating the length changes.
The equation to calculate the length changes is as ollows:
l = l x x T
l = overall linear expansion in [mm]
l = length o the trajectory in question [m]

Tables 23a, 23b, 23c and 23d show the expansion o the various
pipelines depending on the length o the tube and the rise in
temperature.
Calculation o the expansion compensation length
In case o greater expansion, expansion compensators or, incomplicated cases -shaped compensating loops will need to be
tted and calculated. The ormula with which the expansion equalizer
in mm is calculated is as ollows:
Bd = k x (de x l)
Bd = expansion compensation length
k = material constant
= 45 or XPress stainless and carbon steel tube
= 35 or copper tubede = outside diameter o the tube [mm]
l = linear expansion that needs to be compensated [mm]

Without the requirement or the mathematical calculation, we would
get the same result through interpolation o the data in table 20. With
the expansion or the respective section o the pipeline, we need to
calculate the length o the expansion compensator required or its
compensation see gures 12 and 13. Using the nomogram in
graph 1, we get ca. 830 mm. The analytical calculation shows:
Bd = 45 x (22 x 15,36) = 827,2 mm
In case o an -shaped expansion connection, the calculated value o
the expansion equalizer also visible rom gure 14 is to be halved as it
is actually two expansion sections. The value [Bd] is not exactly
divided by two, but should be divided by a actor o 1,8:
Lb = (45/1,8) x (22 x 15,36) = 459,6 mm
or otherwise:
Lb = Bd/1,8 = 827,2/1,8 = 459,6 mm
Graph 2 shows a value or Lb o ca. 460 mm.
As can be seen in gure 12-14, a correct compensation o the
expansion depends also on the placement o xing devices such as
saddles and clips. Never plan or or place tube saddles as a mounting
device close to a tube connection. Clips should be positioned such
that they do not behave as a xed restraint. When there are straight
segments o tube, without expansion compensation, use only one
saddle to prevent possible deormation. Position it as close to the
middle o the straight segment as possible: in this way, any expansion
will be distributed in both directions and the length o the expansionequalizer required will be halved. It is recommended that tube saddles
with a rubber inlay are used as this mufes any possible noise and
vibration and provides a better distribution o the stresses.

The Nomogram in graph 1 enables the ast and accurate
establishment o the expansion bend length [Bd] considering the
respective tube types and the expansion to be compensated [l].
Graph 2 shows the values [Lb] or the installation situation illustrated in
gure 14.
The ollowing is an example o an analytical calculation: A tube
network with a length o 16 m consisting o stainless steel tubing with
a diameter o 22 mm subject to a temperature dierence o 60 K.
When using the equation or calculating the expansion, the result is:
l = 16 x 0,0160 x 60 = 15,36 mm

2.6.2 Flow loss
Every fuid that fows through a tubing system experiences continuous
and local fow resistances that are apparent rom the pressure drop in
the system. There is a dierence between the continuous and the
local pressure drop. The continuous pressure drop is mainly caused
by the fow resistance in straight tube sections which in turn essentially
results rom the riction between the fuid and the tube wall.
Local pressure drops, on the contrary, are those fow resistances thatare caused by turbulence, or instance where there is a change o
internal tube diameter, a tube branch, in an elbow, etc.
Continuous pressure drop
To calculate the total pressure drop resulting rom the fow o fuids in a
straight section o the tubing system, rst determine the pressure drop
over a unit o length and then multiply the total length with this value.
This value can be determined analytically using the Hazen-Williams
ormula.

For those who wish to make these calculations, we reer to the relevant

problem.
