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 多層高強(qiáng)度密封板由天然石墨與不銹鋼箔加強(qiáng)為極端條件制成
