• Very good chemical resistance against most liquids and
chemicals
• Temperature range from approx. –60 °C to 200 °C
[depending on inner ring material]
• No contamination of food, pharmaceutical or medical
products
09 Textiles

• Physiologically harmless, can be sterilised

• Sufficient elastic behaviour
• FEP O-rings can be replaced with standard O-ring seals
without limitation

• No changes to the groove dimensions are necessary

• The O-rings are less flexible than elastomer O-rings due
to the FEP coating. They can only be stretched minimally and
have a lower elasticity or a higher permanent deformation

MATERIALS
Because RTJ-gaskets are used in extreme operating condi-
tions, it is of utmost importance to select the most suitable,
metallic material. In addition to pressure and temperature,

06 Blind Gaskets
the resistance towards the conveyed media has to be con-
sidered. The hardness of the gaskets should usually be lower
than that of the flange material in order to prevent mechani-
cal damage to the flange.
The maximum values for the hardness are specified for the
different materials as per ASME B 16.20 / API 6A.

BOILER GASKETS.
Hand, head & manhole gaskets for oval sealing covers.
DESCRIPTION
Boilers are pressure equipment at risk of overheating in the
sense of the pressure equipment guideline 97/23/EG and may
only be sold if the manufacturer has provided proof that the
necessary safety requirements of this guideline were adhered to
by means of a conformity assessment procedure. The manufac-
turer applies the CE-label and issues an EU-conformity declaration.
Harmonised product standards for boilers are:
• DIN EN 12952-1 up to 17: Water tube boiler
• DIN EN 12953-1 up to 14: Shell boilers
• DIN EN 14222: Stainless steel shell boilers
Different norms and regulations may also be applied. However,
the manufacturer has to prove that he has fulfilled the necessary
safety requirements of the pressure equipment guideline. Boiler
Boilers or boiler plants have great risk potential due to the high
stored energy and the high inner pressure. They are therefore
plants which require monitoring as per the operational safety
directive. Based on these regulations:
• boilers have to be checked by an approved inspection authority
prior to commissioning
• approval for operation has to be obtained from the relevant
authorities
Lid
• in certain intervals checks have to be repeated [inner and

specified there.
The tests are carried out by VdTÜV. If the test results are posi-
tive, then the component approval mark is awarded which has
to be applied to the tested gasket. VdTÜV information leaflets
are important with regards to the adherence to the pressure
equipment guideline and the fulfilment of the AD 2000-policy.
Boilers are fitted with access openings which are used to access
the interior for revision work. The selection of the design is done
in consideration of the condition of the clamping system. Boilers
are equipped with oval sealing covers and interior lid. The lid is
clamped using nuts and brackets and has a self-sealing effect in
the event of overpressure.
The following IDT-boiler gaskets were specifically developed for
use in oval sealing covers and meet all test requirements of the
VdTÜV.

PTFE-PROTECTION & SEALING RING.

For manhole openings with sealing cover.
DESCRIPTION PROPERTIES
Normally a glass lined or enameled protection ring following • Almost universal resistance against chemicals and solvents
DIN 28153 is used to reduce the impact and shock stress of • Blow-out resistant sealing system
the manhole connector. This operational practice has shown,
• Avoids expensive repairs or re-coating of the of the entire boiler
however, that the glass lined protection ring is so severely sub-
jected to the impact and shock stresses due to regular opening, • Avoids use of expensive glass lined intermediate rings and
closing and filling cycles that is has to be replaced frequently at seals don't have to be replaced as frequently
high cost. Chipping of the enamel layer, especially on the inside • Has a long service life even in batch operation and during
of the manhole, filling and sampling connector can even cause frequent opening and closing
expensive repairs or require a new glass lined layer for the entire • Conductive [discharge of electrostatic load], body made from
container. In addition to these repair costs, there are also high conductive Dyneon™ TFM TM
losses due to production interruption of the plant operation. Fur-
thermore, this design also provides the risk that the upper seal
may slightly buckle when the vacuum is applied and therefore APPLICATIONS
becomes untight.
• Operating pressure max. 10 bar
The IDT-PTFE manhole protection and sealing ring was deve­loped
• Operating temperature approx. 200 °C
to have an intermediate ring made from chemically resistant
PTFE protecting the glass lined connector inside wall against • Flange sensitive to stress
impact and shock stresses. The protection ring is equipped • Aggressive and toxic media in gaseous and liquid states
with an apron that reaches inside the connector. We recommend • Pharmaceutical and chemical industry
the use of conductive PTFE to prevent electrostatic charges.
• Batch operation [temperature and pressure changes]
The manhole protection ring is fitted with an O-ring seal on both
sides to achieve gas tightness. This O-ring seal consists of elastic
FPM material with or without PTFE-jacketing and has a con-
centric Kammprofile serrated gasket on the top and bottom to
create a liquid seal.
These two features allow safe sealing at low surface pressure.
A stainless steel sleeve ensures bursting safety for interior pres-
sure as per the requirements of the pressure equipment guide-
line. The calculatory proof has been provided by IDT and is TÜV
confirmed [suitability and design].
The height of the sleeve is approx. 70 % of the thickness of the
base body, the thickness is greater than 2.5 mm. The sleeve can
be fitted on the outside with retaining brackets in order to fix the
manhole ring to the container connector and to prevent possible
leakages by slipping. These brackets also ensure electrostatic
discharge and possible spark discharge is safely avoided.
The following distinction is made with regards to the opening and
closing mechanism and the allocation of the connector:
• Sealing cover only hinged [oval manhole] flat or convex or
concave with a centrally located connector
• Sealing cover hinged or with pivoting device [oval and round
manhole]
• Hinged, convex with an eccentrically located connector
• Pivotable, convex with an eccentrically located connector
• Pivotable, convex with two symmetrically located connectors

BLIND GASKETS.

DESCRIPTION
Blind gaskets are used when locking a pipe for maintenance tasks or to perform pressure tests. The materials, permissible temperatures
and pressure level will generally be specified in a pipe class. Where that is not the case, the required thickness of the blind gasket must
be calculated in accordance with AD 2000 B5 or DIN EN 12952.

APPLICATIONS
Power plants, waste incineration plants, dust removal and filter
systems, cement industry, steel industry, drying technology,
chemical industry, conveyor technology, fan construction,
ventilation technology, marine engineering, etc.

MATERIAL
The multitude of possible material combinations allows the deve­
lopment of optimised solutions, which are generally influenced
by prevalent mechanical, chemical, and thermal conditions. The
structure of the expansion joint is generally based on the following
material groups:
Insulation material
Insulation material - in an appropriate thickness and quality -
will prevent thermal as well as mechanical damage to the actual
sealing foil. The most frequently used insulation material fabrics
are glass fiber, silicate fibers, and ceramic fibers.
Sealing foil
The sealing foil is the actual sealing component of an expan­
sion joint. It is generally sandwiched between two layers of fabric.
The most frequently used sealing foils are made of elastomeres,
PTFE, or stainless steel.

MODELS
Tube expansion joint I Attached to te pipe
Suitable for round or oval cross-sections. Mounting strips

03 Engineering
must be used for rectangular cross-sections, and the duct
walls must be drilled. For a vacuum system it is important AR
to note that the expansion joint bellows will pull inward and
constrict the flow diameter.
In these cases, support rings must be installed. Max. ope­rating
temperatures must not exceed 350 °C, as the fixing point will
take on the temperature of the medium. The attachment of

04 Gaskets
the joint is implemented using multi-part hose clamps for
sizes between Ø 700 mm and 800 mm.
For larger diameters, flange connections are recommended
due to their higher sealing capacity.

05 Dimension Tables
AR
Tube expansion joint I Attached to extracted mounting flange
This installation model covers all cross-section shapes and
sizes. Rectangular connection points will require adequate

06 Blind Gaskets
hose diameters, and a drilling of the duct is not required. Due
to the good temperature reduction properties in the attach­
ment area, an implementation without pre-insulation will be
suitable for temperatures between 400 and 500 °C, and with
pre-insulation for temperatures between 600 and 700 °C.
With relevant structural measures in place, i.e. inner brickwork
lining, temperatures up to 1000 °C will be manageable.

08 Stuffing Boxes
Suitable for use for large dimensions or pre-existing pipeline AR
flanges, higher pressures, and high technical tightness require­
ments. Due to the inferior heat radiation in the attachment area,
operating temperatures should not surpass 450 to 500 °C. With
the use of larger flanges, the expansion joint can be placed
further outward [away from the flow of the medium], and
additionally protected by another insulation or retrofitted

FLANGE SPREADER.

02 Service
DESCRIPTION
Handling of the 9370 flange spreader is simple: Once two
counter-positioned connection bolts have been removed from

03 Engineering
the flange, the flange spreaders can be driven into the newly
vacant holes.
All remaining connection bolts are subsequently removed
or loosened and the flange connection is opened using the
pressure bolt in the flange spreader.
A rigid spacer should be inserted between the flange sheets

04 Gaskets
for additional safety. The gasket can now be replaced. The
system allows the flanges to be spread open enough to allow
inspection. Any damage of the flange contact surface is pre-
vented. Not only gaskets, but also measuring targets, blind
gaskets, and other items be replaced easily.

05 Dimension Tables
AREAS OF APPLICATION FOR DIN FLANGES
Flange spreaders can also be used with other flange types.
We recommend using two flange spreaders concurrently, as
a flange connection should always be spread parallel.
