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 Sprinkler carbon steel tubes

The XPress Sprinkler carbon steel tubes or wet sprinkler systems

are thin-walled precision steel tubes. The tubes are made rom cold

rolled steel that is galvanized using the Sendzimir process. During this

process zinc is brought onto the metal strip, running through a zinc

bath, covering both sides simultaneously. The tube is protected both

on the inside and outside with a zinc layer, with a minimum thickness o

20 m. Ater welding the welding seam is zinc plated additionally. With

the Sendzimir process a good adhesion o the zinc layer and corrosion

resistance are achieved.

2.2.3 Copper Tubing

Copper tubes

Copper tubes that may be used or the XPress copper system or

water applications must comply with the norm EN 1057 R220/R250/

R290. Copper tubes that may be used or the XPress system or gas

applications must comply with the norm EN 1057 R250/R290. EN

1057 is the norm or seamless copper and copper alloyed tubes orpotable water-, gas- and heating installations. Distinction is made

between sot, medium hard and hard alloy tubes indicated by R220,

R250 and R290. The higher the gure, the harder the metal. The

values reer to the tubes tensile strength (220 N/mm2, 250 N/mm2 and

290 N/mm2).


Uninsulated copper tubes certied according EN 1057/DVGW are

considered as incombustible tubes according to German class A

building materials DIN 4102 Part 1.

Heat insulation

For regulations on heat installation, please see the manuacturers

guidelines. To avoid outside corrosion, please note when using

insulating material that the materials contain no elements o ammonia

or nitrate (page 86).

In order to minimize the risk o outside corrosion, insulation material

should as much as possible be used in conjunction with a moisture

barrier. Materials such as Densopaste or a synthetic coating between

the outside o the copper tube and insulation material are possibilities.For installations in the Netherlands the VEWIN work sheets should be

ollowed.

Applications

- All potable water installations in accordance with the German PotableWater Decree (TrinkwV) and EU guideline 98, DIN 50930 Part 6 and incompliance with DIN 1988.

XPress stainless steel GAS and copper GAS fttings in the dimen-

sions 15-54 mm or gas installations must be pressed using

Novopress pressing jaws/pressing slings. Approvals or other

suppliers o press tools, jaws and slings such as Rems can be

suitable or local approvals such as Gastec and KVGB.

When using XPress stainless and carbon or sprinkler installations,

please make sure to ollow up the guidelines or installation andapproved tools, which can be ound in the VSH XPress Sprinkler

system catalogue which is available on request or can be down-

loaded rom our website www.vsh-fttings.com.

Threaded ttings

The XPress product range also includes components with inner- and

outer threads or connection with other threaded parts o a tube

network (e.g. valves, ttings). Inner- and outer threads are

manuactured according to DIN 2999/ISO 7/1 or carbon and stainless

steel ttings. Inner threads are manuactured according to BS 2779/ISO 228/1 and outer threads are manuactured according to DIN

2999/ISO 7/1 or copper press ttings.

Hemp or other sealants without chloride are suitable or the threads o

stainless steel press ttings. Tefon thread sealing band may not be

used in conjunction with stainless steel due to the water soluble

chloride ions it contains. With threaded couplings, we recommend to

carry out the sealing beore the pressing, in order not to stress the

press connection.

Screw ttings (copper)

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.

Suitabillity o O-rings

The standard ttings or water and the central heating are provided

with EPDM O-rings. The type o O-ring which has to be used depends

on the application and the medium. For this reason the gas press t-

tings are provided with (H)NBR O-rings. For special applications, such

as oil-containing media or high temperatures, the Viton/FPM

O-ring has to be installed.

Should you have the need or applications which are not mentioned in

the table, always contact us to enquire whether the medium is suitable

or use in combination with the type o press tting you are using.

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

2.3 .3 Alternative applications or the fttings

The choice o ttings and tubes depends on the assembly situation,

the medium and the operating conditions. For approval o the use o

XPress ttings or other applications such as water, compressed air

and gas please contact your local agent or VSH. Always make sure that

installations comply with local regulations.

2.3 .4 Electrical heat tracingXPress stainless steel, carbon steel and copper may be used in

conjunction with electrical heat tracing. In the case o XPress stainless

steel, electrical heat tracing may be used i the inside o the tube is

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.

Figure 6: Marking the depth

Figure 7: Check tting/tube

Figure 8: Assembly tting/tube

2.5


24/149

46


47

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]

T = temperature dierence [C]

= linear expansion coecient, which is:

or stainless 1.4401 tubing = 0,0160 mm/m

or stainless 1.4521/1.4520 tubing = 0,0104 mm/m

or carbon steel tubing = 0,0108 mm/m

or copper tubing = 0,0170 mm/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.

discipline literature. For the normal installation calculations, appropriate

problem.
