A line of ceramic fibre rope products, which maintain their integrity when exposed to temperatures up to 1260C, is available from Agis Manufacturing Company, specialist in high temperature sealing products. Agis ceramic fibre rope is a soft, pliable material designed for gasketing, packing and sealing applications in the chemical, petrochemical, foundry, metalworking, heat treating and other industries where extreme high temperatures and/or corrosive service conditions are common. Recommended applications include furnace linings, gas turbine muffler seals, expansion joint seals, insulation for laboratory ovens, gasketing for pollution control equipment and vacuum degassing equipment; super heater seals; gasketing and seals for doors on industrial boilers, wood burning stoves, coke ovens and furnaces, among other applications.
Agis ceramic fibre rope is manufactured by twisting or braiding long-staple, high-strength alumina and silica fibres together with an organic carrier.
The carrier, which comprises about 20% of the fibre, is included to facilitate carding.
At low temperatures, the carrier burns out without affecting the properties of the ceramic fibre.
Agis ceramic fibre rope is lightweight, low in thermal conductivity, immune to thermal shock, resistant to flame erosion, chemically stable, highly resilient at working temperatures, and maintains its tensile strength even after prolonged exposure to high temperatures The product is available: in a normal, three-play twisted form, which is suitable for most applications; in high density twisted form for applications requiring greater abrasion resistance; and in square or round braided configurations, where greater density and increased resiliency are required.
Options include: encasement in wire mesh for additional abrasion resistance or with graphite coating for increased lubricity.
