SIGRAFLEX HOCHDRUCK PRO
TA Luft-compliant multilayer high-strength sealing sheet made from
natural graphite with stainless steel foil reinforcement for extreme conditions
SIGRAFLEX HOCHDRUCK PRO is a multilayer high-strength-
graphite sealing sheet comprising thin layers of high-purity
graphite 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 special
adhesive-free process. As a result, the sheets have outstanding
mechanical properties. The sealing sheet is impregnated to
reduce leakage and improve handling.
SIGRAFLEX HOCHDRUCK PRO allows end users in the process
industry to cover almost their entire gasket requirements with
a reliable and safe product.
Applications
● For difficult and mechanically highly stressed sealed joints
(in tongue-and-groove and flanges with special dimensions,
process equipment, heat exchangers, etc.); also suitable for
all common pipework and vessel flange designs
● 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
● Operating temperatures range from – 250°C up to 550°C
depending on chemical resistance. Life time might be limited
at high temperatures. Consult the manufacturer when
application temperatures exceed 450 °C. Please refer to our
technical guideline regarding thermal stability.
● Chemical, petrochemical, refinery and nuclear industries
● Steam pipework and boilers in power generation plants
● Heat transfer oils and heating equipment
● Inspection glasses, pumps, fittings and valves
● Existing plants
Properties
● Reduction in fugitive emissions due to high leak-tightness
● Complies with the TA Luft leakage requirements for all
sheet thicknesses
● Outstanding maximum permissible gasket stress
● High operational reliability, increased plant availability
● Excellent oxidation resistance
● Very high blow-out resistance and mechanical strength
● Very high fault tolerance during assembly and operation
● Good chemical resistance
● Long-term stability of compressibility and recovery,
even under fluctuating temperatures
● Good scratch resistance and antistick properties due
to special impregnation
● No measurable cold or warm flow characteristics up
to the maximum permissible gasket stress
● No aging or embrittlement (no adhesives or binders)
● Ease of processing
● Asbestos-free (no associated health risks)
Sigraflex hochdruck prota luft-compliant 多层高强度密封板由天然石墨与不锈钢箔加强为***条件制成
Sigraflex hochdruck pro是一种多层高强度石墨密封板,由薄层高纯石墨箔和0.05毫米厚的不锈钢箔组成。
根据所需的板材厚度,几层石墨和不锈钢箔通过特殊的无粘合剂工艺连接在一起。因此,这些薄片具有优异的机械性能。这种密封片经过浸渍,以减少泄漏和提高手感。sigraflex hochdruck pro使加工业的最终用户能够用一种可靠和安全的垫片来满足他们几乎所有的要求。
应用
适用于难度大、机械强度高的密封接头(特殊尺寸的舌槽和法兰、工艺设备、热交换器等) ;也适用于所有常见的管道和容器法兰设计
适用于直径1500毫米以下的单片垫片设计;适用于直径1500毫米以上的双层结构,例如适用于从真空至250巴的腐蚀介质操作压力;
根据耐化学腐蚀性能,操作温度范围从-250°c到550°c不等。 在高温下,生命的时间可能是有限的。 当使用温度超过450°c时请咨询制造商,请参阅我们关于热稳定性的技术指南。
