SIGRAFLEX UNIVERSAL

Impregnated sealing sheet made from natural graphite

with tanged stainless steel reinforcement

SIGRAFLEX UNIVERSAL is an adhesive-free graphite sealing-

 sheet made from flexible graphite foil with one or two tanged

 stainless steel reinforcements. The sealing sheet is impreg-

nated to reduce leakage and improve handling.

Applications

●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 100 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.

●Gaskets for the chemical, petrochemical and refinery

 industries

●Steam pipework in power generation plants and

 heating equipment

●Existing plants

Properties

●High operational reliability, increased plant availability

●Excellent oxidation resistance

●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)

●Asbestos-free (no associated health risks)

Sigraflex通用浸渍密封板由天然石墨与切线不锈钢加强

Sigraflex万能密封板是由柔性石墨箔与一个或两个缠结的不锈钢增强材料制成的无粘性石墨密封板。 为了减少泄漏和提高操作性，在密封板上加了密封条。

应用●适用于所有普通管道和容器法兰设计●适用于外径达1500毫米的单件垫片设计;对于直径超过1500毫米的结构，例如，对于真空度达100巴以下的工作压力，建议采用分段和交错连接的双层结构●适用于腐蚀性介质的工作温度范围为-250°c至550°c，具体取决于耐化学腐蚀性。 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。*化学、石油化学和炼油工业用垫圈●发电厂的蒸汽管道和加热设备●现有工厂
