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 re 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 e

●Asbestos-free (no associated health risks)
