Applications:
power generation, refineries, heat genereation, steel works, glass production, pulp and paper, shipyards, chemical industry, gaskets used in non-pressurized air installations, coal dust system, exhaus installations, furnace and boiler chamber covers, burners, in all places where the temperature is high, but without pressure; used also to contain oxidizing media, such as nitric acid, sulphur trioxide etc. in pressure installa-tions; gaskets have very good chemical and fire resistance.

SPETOTERM® TUI 810 is a soft, easily formed material, manufactured from flogop plates bonded with special silicone filler, firbre-free material, main applications: exhaust systems, sealing of heat furnaces, for strongly oxidising fluid media and heat shields; material can be punched, cut with knife or special cutters; often delivered as full face gasket, standard thickness 1mm, also available in thicknesses 2.0, 3.0 mm; standard sizes of the sheet 1000x1000mm; for dimensions above 1000mm recommended form of delivery is the gasket on the steel core TUI 810I , soft elements of the gaskets may then be made from segments, recommended service temperature up to 750°C.

SPETOTERM® TUI 70I gasket family is manufactured from the same materials as for TUI 70 series, but have the ste-el core; such gasket has better mechanical stability in service, and importantly during assembly; steel core allows for the production of the gaskets with dimensions exceeding those of sheet, depending on the material used the fol-lowing styles are available: TUI 70I N85 (up to 850o C), TUI 70IN110 (up to 1100o C), TUI 70IB120, TUI 70IG120 (up to 1200 oC) the difference between TUI 70IB120 and TUI 70IG120 lies in conformability of the layers; in the lat-ter case, layers are much harder which results in thicker gasket after assembly, typically, metal core is manufactu-red from carbon steel.

SPETOTERM® TUI 830 is the standard material used in manufacture of gaskets with perforated stainless steel core; mica flakes bonded with special binding agent show almost absolute inertness in contact with strongly oxidising media such as HNO3 lub H2SO4 even at elevated temperatures; stainless steel reinforcement improves mechanical strength of the material, however, its application is limited to approximately 650oC, in order to achieve better seal-ability inner steel or silver eyelet is recommended (TUI 831).

SPETOTERM® TUI 810 I gasket is manufactured in the similar way to TUI 810I, but corrugated ring is used as the metal core, which improves recovery, ensures better forming when the flanges are misaligned or uneven, corruga-ted ring also creates beneficial effect of higher loads in the areas of the corrugation peaks, which improves sealabi-lity, thickness of corrugated insert 1,5mm, also in this case, metal ring facilitates manufacture of segment gasket of dimensions over 1000mm.

SPETOTERM® TUI 810 J gasket is manufactured in the similar way to TUI 810I, but corrugated ring is used as the metal core, which improves recovery, ensures better forming when the flanges are misaligned or uneven, corruga-ted ring also creates beneficial effect of higher loads in the areas of the corrugation peaks, which improves sealabi-lity, thickness of corrugated insert 1,5mm, also in this case, metal ring facilitates manufacture of segment gasket of dimensions over 1000mm.

SPETOTERM® TUI 50 is the square braided packing, used to seal the furnace doors, installations containing melted metals in steel works, fire-safe zones in the pipelines, thermal dilatations, ship hauls; the packing may be also im-pregnated with graphite or PTFE; depending on material used the following styles can be distinguished: TUI 50S glass fibre up to 450°C; TUI 50S75 high temperature glass fibre up to 750, TUI 50C ceramic fibre up to 1000° C (1200°C), TUI 50CR- ceramic fibre with wire reinforcement up to 1000oC (1200°C); due to ecological consideration, the sealing is manufactured from special glass fibre S75. |
