SIGRAFLEX HOCHDRUCK
Sealing Sheet Made from Natural Graphite
with High-Integrity Stainless Steel Foil Reinforcement
for Extreme Conditions
SIGRAFLEX HOCHDRUCK
Our Contribution to Environmental Protection
SIGRAFLEX HOCHDRUCK
is a multilayer high-strength graphite sealing sheet
comprising 0.5 mm thick layers of high-purity graph -
ite foil and 0.05 mm thick stainless steel foils.
Depending on the sheet thickness required, several
layers of graphite and stainless steel foil are joined
together in a patented adhesive-free process. As a
result, the sheets have outstanding mechanical prop -
erties. The sealing sheet is impregnated to reduce
leakage and improve handling.
SIGRAFLEX HOCHDRUCK allows end users in the
process industry to cover almost their entire gasket
application range with a reliable and safe product.
Applications
For difficult and mechanically highly stressed
sealed joints (in tongue-and-groove and
special-dimension flanges, process equipment,
heat exchangers); also suitable for all common
pipework and vessel flange designs
Recommended for one-piece gaskets up to
1500 mm outside diameter; for diameters over
1500 mm as two-layer structures with segment ed sections and staggered joints, for instance
For high internal pressures of up to 250 bar
For corrosive media
Suitable for a broad range of temperatures
from -250°C to approx. 550°C; for appli cations at more than 450°C, users should
request our advice

Assembly instructions
For assembly, use dry and undamaged gaskets only.
Wet graphite gaskets must not be fitted unless first
dried completely. The sealing faces must be clean,
dry and free from grease. Do not use release agents!
Position the gasket centrically and avoid mechan -
ical stresses during assembly. An assembly aid
can be used if necessary. To facilitate assembly in
difficult posi tions, the gasket may be fixed by using
a commer cially available adhesive. However, the
adhesive should be applied sparingly at a few
points only.
Align the flanges as plane-parallel as possible. First
hand-tighten the bolts and then tighten the bolts in
a crosswise order to about 50% of the maximum
torque value, in the second stage to about 80% and
to the full value in the third stage. All bolts must be
tightened to the specified bolt load, so the torque
must be checked repeatedly. Our detailed assembly
instructions are available on request.

装配指南，只使用干的和未损坏的垫圈。湿的石墨垫圈必须首先完全干燥。密封面必须清洁，干燥，无油脂。不要使用脱模剂!将垫圈固定在中心位置，避免在组装过程中产生机械应力。 如果有必要，可以使用集合助手。 为了便于在困难的位置组装，垫圈可以使用一种通用的粘合剂来固定。 但是，粘合剂只能在少数几个点上使用，要尽可能使法兰平行排列。 ***手资料-紧固螺栓，然后横向紧固螺栓约50%的扭矩值，在***阶段约80%和充分值在第三阶段。 所有螺栓必须按规定的螺栓负荷紧固，因此必须反复检查扭矩。 我们详细的装配说明可以根据要求提供。
