SIGRAFLEX APX2 HOCHDRUCK
Multilayer high-strength sealing sheet made from natural graphite with
stainless steel foil reinforcement for high-temperature applications
SIGRAFLEX APX2 HOCHDRUCK is a multilayer high-strength
graphite sealing sheet–designed for high-temperature
applications.
The sheet is comprised of 0.5 mm thick layers of highly
oxidation resistant SIGRAFLEX APX2 flexible graphite and
0.05 mm thick layers of stainless steel foil, manufactured
with SIGRAFLEX HOCHDRUCK technology.
SIGRAFLEX APX2 HOCHDRUCK was developed for end users
in the process industry to cover a broad range of demanding
gasket requirements with a reliable and safe product.
SIGRAFLEX APX2 HOCHDRUCK is specifically designed for
high temperature flat gasket applications.
Applications
●Operating temperatures range from–250°C up to 580°C
depending on chemical resistance. Life time might be limited
at high temperatures. Consult the manufacturer when
application temperatures exceed 480°C. Please refer to our
technical guideline regarding thermal stability.
●All common pipework and vessel flange designs as well as
difficult and highly stressed sealed joints.
●For one-piece gasket designs up to an outside diameter of
1500 mm; for diameters above 1500 mm, for example
two-layer structures with segmented sections and staggered
joints are recommended.
●For operating pressures from vacuum up to 250 bar
●For corrosive media
●Steam pipework and boilers in power generation plants
●Heat transfer oils and heating equipment
●Inspection glasses, pumps, fittings and valves
●Nuclear power generation plants
●Pulp and paper mills
●Existing plants
Properties
SIGRAFLEX APX2 HOCHDRUCK combines the outstanding
characteristics of both SIGRAFLEX APX2 graphite foil and
reinforced sheets manufactured with SIGRAFLEX HOCHDRUCK
technology:
●Increased gasket life and improved operational safety due
to very high oxidation resistance
●Reliable product characteristics for high plant security and
availability
●Outstanding maximum permissible gasket stress
●Very high blow-out resistance and mechanical strength
●Very adaptable sealing material during gasket assembly
●Good chemical resistance
●Long-term stability of assembly load and gasket stress
●No measurable cold or warm flow characteristics up to the
maximum permissible gasket stress
●No aging or embrittlement (no adhesives or binders)
●Very easy to cut into required sealing shapes, even with
conventional cutting equipment/tools
●Asbestos-free (no associated health risks)
