 Properties/applications |
 Excellent heat resistance, continuous
temperatures up to approx. 800℃,
short-term
temperatures up to approx.
900℃.
Non combustible
Good resistance to media
(depending on the metal used)
Good gas-tightness at medium loads.
No aging at high temperatures.
Can be used for very high operating
pressures, in which case the use
of maximum
screw torques is
recommended.
High compressibility and good
adaptability ; also suitable for use
in existing
plants.
High compressive strength
Asbestos-free, physically harmless,
disposable at domestic refuse dumps.
Fulfills the requirements of the Fire
Safe Test.
Troublefree handling for storage, transport, installation and removal ; mechanical
strength assured
by metal reinforcements.
No special requirement applicable to flange sealing surfaces, flange type
C is sufficient
(see installation recommendation).
High quality, reinforced seal complying with accident prevention regulations,
high blow-out resistance.
Especially suitable for use in hot air and incineration plants, also exhaust
systems for internal
combustion engines. |
