Downtime is an extreme cost factor in any piece of equipment, so maintenance work must be kept to a minimum. After years of use, flat gaskets often stick to flanges. So, when it comes to their replacement it takes additional time and effort to do so. And, there is also the risk of damaging the flange when removing the residues.
SGL Carbon offers high-quality sealing solutions also in reduced adhesion. SIGRAFLEX MF flat gaskets meet the very highest demands in terms of separation behavior and mechanical strength.
SIGRAFLEX MF, a three-component sealing sheet made from flexible natural graphite, stainless steel and PTFE, guarantees minimum leakage and total cost of ownership at maximum safety.
SIGRAFLEX MF, technical data sheet
The sealing sheet SIGRAFLEX EMAIL was specially developed for use in PTFE envelope gaskets.
SIGRAFLEX EMAIL is a multilayer, adhesive-free sealing sheet made from flexible SIGRAFLEX Z foil reinforced with two 0.05 mm thick stainless-steel foils. The sheet meets the highest demands for mechanical strength at elevated temperatures.
Flat gaskets made from SIGRAFLEX BSSC graphite sealing sheets are particularly suitable for flanges, connectors and joints in the chemical and petrochemical industries, refineries, power plants including nuclear power plants and pulp and paper mills.
SIGRAFLEX BSSC is a bonded sealing sheet made of SIGRAFLEX flexible graphite B grade foil reinforced with a stainless steel foil. The sheet can be used for one-piece gaskets up to an outer diameter of 1524 mm (60”), for larger diameters e.g. as two-layer structures with segmented sections.
Our SIGRAFLEX sealing materials made from expanded flexible graphite have proven their long-term stability and strength under extreme operating conditions over the course of many years.
