Flange seals for the complete sealing of flanges

Flange seals are flat seals (2D-objects) being installed between the mounting surface and the flange to be mounted. Just due to their assistance a complete sealing is possible. They are part of the static sealing elements and at Steinbach AG they are available from different materials and in most diverse sizes. Consequently this kind of sealing comprises much more than the classical 2D-O-rings.

Benefits and advantages of flange seals

Flange seals are used wherever gaseous, pasty or liquid media are transported in pipes. They are subject to the relevant standard DIN and contribute significantly to the safety of the plant and to the environmental protection. A more and more challenging environment, for example higher operating pressures and flow rates in the plants and the more and more aggressive media and higher operating temperatures require a careful selection of the qualities and materials of flange seals. The seals are low-wear and depending on the area of application they are cold-resistant, high-temperature resistant, food compatible and chemically resistant.

Summary of the benefits of flange seals:

  • low-wear seals
  • flexibly usable
  • easy to install
  • available in different sealing materials
  • temperature resistant, chemically resistant and food compatible depending on the material

Available materials for flange seals

Gasket paper and elastomers like caoutchouc, sponge rubber and silicones are often used materials for flange seals.

Caoutchouc:

Among others, ethylene propylene diene rubber (EPDM), fluorinated rubber (FKM), ethylene vinyl acetate rubber (EVM) and acrylonitile betadiene rubber (NBR) are used for flange seals. In addition to a high thermal resilience EPDM disposes of a very good chemical resistance to polar media and therefore is preferably used for O-rings getting into contact with steam, water, acids, alkalis and  coolants, for example in the food industry, in the equipment and machine tool industry as well as in mechanical engineering and in vehicle construction. FKM equally is chemically and thermally stable. NBR disposes of good mechanical qualities and is resistant to mineral oil-based lubricating oils and greases.

Sponge rubber:

Sponge rubber is a rubber with mainly closed pores. The elastic foam disposes of a very high abrasion resistance and depending on the material mix it is resistant to temperatures, ageing and oil as well as flame retardant.

Silicones:

Silicones in general are hydrophobic, heat-resistant, dielectric and normally are physiologically compatible. Flange seals made of silicone are used for example in the pharmaceutical and vehicle industry.

Gasket paper:

Gasket paper is very resilient and durable as well as simply and precisely applicable, for example in car manufacturing and in machines of most different kinds.
