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通用浸漬密封板由天然石墨與切線不銹鋼加強(qiáng)

Sigraflex萬能密封板是由柔性石墨箔與一個或兩個纏結(jié)的不銹鋼增強(qiáng)材料制成的無粘性石墨密封板。 為了減少泄漏和提高操作性，在密封板上加了密封條。
