Selection table bellows with flanges
General
Our rubber bellows are made from various elastomers and provide the flexible element in
pipework that is indispensable in todays technically advanced plant and machinery installations. By using the best quality proven rubber compounds and a construction based on many
years of experience, our rubber bellows are produced to a high quality standard to guarantee
maximum safety and performance.
The rubber bellows provide:
 Compensation of thermal or mechanical movement of pipework in axial, lateral or angular
directions.
 Absorption and isolation of vibration combined with damping of pipework borne sound transmission.
 Reduction of pressure pulses in pipework.
 Flexible joint faces which provide built-in sealing within the bellows construction.
 Compensation for pipework misalignment on flexible mounted installations.
Our rubber bellows are available in standard constructions, type 1A, 1B, 1C and 1S, each
available in different rubber qualities, so that the correct rubber bellows can be selected for
every kind of medium and temperature. Next to that the high pressure bellows are available on
request.

Average installed insulation is about 25 dB, a figure which is further improved by compressed
installation. The standard flange range is made of carbon steel S235JR, drilled according to
DIN PN10/16 and electrolytic galvanized.
RB / SELECTION TABLE / AUG 2012
BELLOWS WITH FLANGES
The maximum working pressure is 16 Bar ( 10 Bar* ) with a test pressure of 25 Bar and even
a burst pressure of over 60 Bar ( 30 Bar* ) .
( * for bellows larger than NB 150)
SELECTION TABLE
Rubber bellows with flanges have a special flow-assisting convoluted shape of the bellows
which minimize detrimental turbulence of the medium and pressure loss.
High tensile strength texture cord plies combined with proven synthetic rubber mixes guarantee maximum reliability and an extended working life.
The rubber bellows are produced with a vulcanized steel ring to guarantee a perfect sealing of
the profiled sealing rings in the special chamber of the swivel flanges.

BELLOWS WITH HOSE CLAMPS
SELECTION TABLE
Selection table bellows with hose clamps
General
Our rubber bellows are made from various elastomers and provide the flexible element in
pipework that is indispensable in todays technically advanced plant and machinery installations. By using the best quality proven rubber compounds and a construction based on many
years of experience, our rubber bellows are produced to a high quality standard to guarantee
maximum safety and performance.
The rubber bellows provide:
 Compensation of thermal or mechanical movement of pipework in axial, lateral or angular
directions.
 Absorption and isolation of vibration combined with damping of pipework borne sound transmission.
 Reduction of pressure pulses in pipework.
 Compensation for pipework misalignment on flexible mounted installations.
Our rubber bellows are available in standard constructions, type 3K, 3K2 and 4K, each available in different rubber qualities, so that the correct rubber bellows can be selected for every
kind of medium and temperature.

TABLE
As an addition to the flanged bellow range our 3K and 3K2 rubber expansion joints have been
designed especially to provide small, low weight expansion joints which are both very flexible
and simple to install.
The 3K ranges accommodate misalignment, axial and lateral pipe work movements and dramatically reduce the transmission of noise, vibration and shock.
High tensile strength texture cord plies combined with proven synthetic rubber mixes guarantee maximum reliability and an extended working life.
The burst pressure safety factor is 5 times the working pressure of 4 Bar.
The minimum work pressure is 70 kPa ( abs ) and can be lowered by fitting a vacuum support ring. Average installed insulation is about 25 dB, a figure which is further improved by
compressed installation. The maximum working pressures are guaranteed by using the recommended power clamps in galvanized or stainless steel.

The bellows are manufactured in brown synthetic rubber, with a black inner liner, reinforced
with synthetic fabric to achieve a high mechanical strength. They are suitable for use with
cooling water, fuel and lubrication oil pipework systems up to 220°C.
The burst pressure safety factor is 3 times the working pressure of 4 bar.
The minimum workpressure ( absolute ) is 80 to 90 kPa, depending on compensator size
and can be lowered by fitting vacuum support rings. The mentioned pressures are guaranteed
by using the recommended ( stainless steel ) clamps according to the table above.

RB / 4K SILICONE / AUG 2012
Because silicone rubber is permeable to hydrocarbons, fluorosilicone liners are often used in
automotive applications to prevent oil seepage through the hose wall. This seepage could
otherwise swell and damage the hose and also leave a sticky deposit on the outside of the
hose that attracts dirt. We recommend and use fluorosilicone rubber ( FMVQ ) for liners because of its stable physical properties throughout the operating temperature range of -55°C to
+250°C. Unlike fluorocarbon ( F KM or FPM ) liner materials fluorosilicone does not echibit
thermoplastic tendencies, this allows the dynamic properties of the fluorosilicone liner to more
closely follow those of the hose outer resulting in a product that does not become brittle at low
temperatures or excessively soft at high temperature. Fluorosilicone lined turbocharger and
intercooler hoses are often specified for use on engines that have to meet Euro 3 and 4 emission levels and therefore have crankcase oil mist recirculated through the induction system.
As an addition to the 3K range, the 4K multiple bellows with support rings have been designed
especially to provide small, low weight bellows which combine flexibility and high medium
temperature with simple installation. The 4K ranges accommodate misalignment, axial and
lateral pipework movements and reduce the transmission of noise, vibration and shock.
The bellows are manufactured in brown synthetic rubber, with a black inner liner, reinforced
with synthetic fabric to achieve a high mechanical strength. They are suitable for use with
cooling water, fuel and lubrication oil pipework systems up to 220°C.
The burst pressure safety factor is 3 times the working pressure of 4 bar. The minimum workpressure ( absolute ) is 80 to 90 kPa, depending on bellow size and can be lowered by fitting
vacuum support rings.

Silicone elastomer hoses of various shapes that use a peroxide vulcanising system, high temperature stable iron oxide pigmentation, meta-aramid fabric reinforcement and a silicone or
fluorosilicone liner when necessary.
Typical applications are automotive turbocharger outlet, hot side intercooler hoses and EGR
connectors. They are also used in many industrial high temperature applications where they
are suitable for use at working temperatures of up to 220°C and intermittent exposure up to
250°C.
Fluorosilicone lined hoses are generally specified for use on engines that have to meet Euro 3
and 4 emission levels and have crankcase oil mist recirculation. The fluorosilicone liner prevents oil permeation through the hose wall and subsequent hose failure.
Please see separate data sheets for silicone and fluorosilicone physical properties.
Reinforcement plies are heavy duty knitted or woven meta-aramid ( otherwise known as
Nomex® or Conex® ) fabric depending on the hose type, diameter and expected severity of
the service conditions.
As an addition to the 3K range, the 4K multiple bellows with support rings have been designed
especially to provide small, low weight bellows which combine flexibility and high medium
temperature with simple installation.
The 4K ranges accommodate misalignment, axial and lateral pipework movements and reduce the transmission of noise, vibration and shock.
The bellows are manufactured in brown synthetic rubber, reinforced with synthetic fabric to
achieve a high mechanical strength. They are suitable for use with cooling water, fuel and
lubrication oil pipework systems up to 220°C.
The burst pressure safety factor is 3 times the working pressure of 4 bar. The minimum workpressure ( absolute ) is 80 to 90 kPa, depending on bellow size and can be lowered by fitting
vacuum support rings.
EXAMPLE

RB / 4K SiLICONE / AUG 2012
Silicone elastomer hoses of various shapes with polyester fabric reinforcement having an
upper temperature capability of 170°C.
For higher temperature rated hoses please refer to the aramid reinforced hose data sheet.
Reinforcement is from two to five plies of medium duty knitted polyester fabric depending on
the chosen diameter and expected severity of the service conditions.
A “ rubber only ” liner is used to prevent the leakage which could otherwise occur due to
exposed fabric on the inside of the hose. Hoses are available in our standard colours of Blue,
Black, Red or Yellow and special colours can be supplied depending on quantity. Surface
finish is shiny gloss for straight lengths and cut pieces, with a choice of gloss or semi-matt
cloth finish for elbows and reducers.
Typical applications are vehicle cooling systems, cold side intercooler air hoses and general
industrial use within the temperature range of -55°C to +170°C. Helical wire reinforcement can
also be incorporated if required for resistance to collapse under vacuum and for resistance to
kinking at tight bend radii. Polyester reinforced silicone hoses are constructed to meet the
general requirements of SAE J20R1 or R4 HT CLASS A. Hoses with integral helical wire reinforcement meet the general requirements of SAE J20R2 or R5 HT CLASS A.
As an addition to the 3K range, the 4K multiple bellows with support rings have been designed
especially to provide small, low weight bellows which combine flexibility and high medium
temperature with simple installation.
The 4K ranges accommodate misalignment, axial and lateral pipework movements and reduce the transmission of noise, vibration and shock.
The bellows are manufactured in blue synthetic rubber, with a black rubber liner, reinforced
with synthetic fabric to achieve a high mechanical strength. They are suitable for use with
cooling water and air pipework systems up to 170°C.
The burst pressure safety factor is 3 times the working pressure of 4 bar. The minimum workpressure ( absolute ) is 80 to 90 kPa, depending on bellow size and can be lowered by fitting
vacuum support rings.

SILICONE
General WRAS
A specially developed silicone material, which is used as a liner in hoses that will carry drinking water.
This rubber compound retains all the desirable properties of silicone elastomers in terms of
temperature range and durability but in addition is non-tainting, toxicologically inert and will not
support bacterial growth.
This material is recognized by the Water Regulations Advisory Scheme ( WRAS ) and carries their certificate number 0412511.
This material can be incorporated into standard silicone hoses or for more demanding applications. For instance in the Rail Transport sector, a flame retardant - low smoke low toxicity
outer may be used.
As an addition to the 3K range, the 4K multiple bellows with support rings have been designed
especially to provide small, low weight bellows which combine flexibility and high medium
temperature with simple installation.
The 4K ranges accommodate misalignment, axial and lateral pipework movements and reduce the transmission of noise, vibration and shock.
The bellows are manufactured in white synthetic rubber, reinforced with synthetic fabric to
achieve a high mechanical strength. They are suitable for use with drinking water. The burst
pressure safety factor is 3 times the working pressure of 4 bar. The minimum workpressure
( a bsolute ) is 80 to 90 kPa, depending on bellow size and can be lowered by fitting vacuum
support rings.

VACUUM
SUPPORT RING
Vacuum support ring
General
Vacuum support rings allow for higher vacuum in the bellows according to the table.
The stainless steel ring ( AISI 316Ti ) can be installed before delivery but also afterwards for
rubber bellows with flanges at nominal bores up to 300 mm.
Larger sizes as well as nylon vacuum support rings need to be installed at the factory.
Note: Using vacuum support rings will limit the movement range by 50% in all directions.

FLAME GUARD
Type Flame guard
General
Flame guards protect the rubber bellows for overheating from the outside.
These covers are made of various layers of fabric materials consisting of high temperature
glass fiber and are resistant against oil, chemicals and ageing.
Flame tests have proven a rubber bellows to withstand 800°C heat and flames for 30 minutes.
The covers can be installed easily after installation of the rubber bellows and can be removed
the same way and will not interfere with the function of the rubber bellows.

Rubber Bellows
Installation instruction
Precautions prior to installation
- Install the rubber bellows at a visible and easy accessible position for inspection and replacement.
INSTALLATION
INSTRUCTION
- The bellows diameter should match with the size of the pipe inside/outside diameter and in
case of rubber bellows with clamps only very small differences are acceptable to secure a
good sealing.
- Check all data of the bellows like type of fluid, temperature and pressure, compared with the
system where it will be used for, before starting installation.
- For a safe operation it is important to use correct counter flanges. The sealing face of the
flange needs to be machined smooth and must cover the rubber sealing face for at least 60%
of the rubber bellows. We recommend to use welding neck flanges as those assure a proper
sealing of the bellows.
- In case of an enlarged inner diameter of the flange loose rings of at least 4 mm need to be
applied to secure a correct sealing.
- In case there will be vacuum in the system the use of a vacuum ring is recommended and
can be installed in the bellows easily before installation if it is not included already.
- Rubber bellows produce reaction forces as a result of the pressure in the pipe work and
these forces can be absorbed by using adequate fixed points.
- Use bellows with extension limiters if there are no fixed points.

RB / INSTAL. INSTR. / AUG 2012
the pipes from damage they are to be properly anchored in order to take care of these reactions forces ( Fr ) . The reaction force of the bellows can be calculated by the formula as follows.
Fr = A x P x 0,01
Fr = reaction force in kN
A = effective cross sectional area in cm2 – see relevant table of bellows
P= ( actual pressure in Bar or kp/cm2 ) x 0.01
- The distance from the bellow to the first fixed point or pipe guide should not be larger
than 4x pipe diameter ( L1 )
- The distance between pipe guides and fixed points in horizontal pipe work should not
be bigger than 14x pipe diameter ( L 2 )
- The distance between pipe guides and fixed points in vertical pipe work should not
be bigger than 20x pipe diameter ( L 3 )
- Use bellows with extension limiters if there are no fixed points.

INSTALLATION
INSTRUCTION
Installation
- During installation the rubber bellows might be compressed or stretched slightly to eliminate
misalignments of the system however the allowable maximum values of the movements will
change accordingly.
- If the rubber bellows needs to be stretched to install, please pay attention to the collar of the
sealing ring of the bellows being kept in position and will not tear out of the groove of the
flange.
- Load the rubber bellows to compression necessary for installation between the flanges to the
allowable maximum according to the tables ( values depend on type of bellows )
- If possible install the bellows in such a way that the production date is visible in order to
make a better review for replacement.
- It is recommended to insert the bolts from the rubber bellows side of the flanges however if
this is not possible the loose threaded end must not interfere with the maximum movements of
the bellows.
- Do not use sharp tools which may damage the rubber.
- Install the bolts crosswise.
- Apply the torque crosswise ( 3 steps ) by tightening the bolts by hand.
- Fasten all bolts crosswise with 50 Nm.
- Final torque to be applied crosswise according to the table.

Precautions after installation
- In case of works the rubber bellows needs to be protected against heat, flames and sparks
and in the event of these works protection of the bellows has to be made.
- Permanent radiation heat needs to be avoided or use a flame protection guard.
- Do not exceed maximum permissible temperature according to the tables to secure long life
time of the product.
- If a test pressure will be applied on the system the maximum value is the maximum working
pressure x 1,5.
- Do not paint the surface of the rubber and keep the part clean in order to allow adequate
inspections.
- Bellows do not need maintenance however are subject to wear and need to be inspected
every year at leakage, cracks and other deviations.
