Ceramic fiber tubes are manufactured using high-purity alumina-silicate fibers, which are known for their exceptional thermal and mechanical properties. These fibers are spun into tubes through a specialized process that ensures uniform density and structure. The tubes are available in various diameters and lengths to meet specific application requirements. They are designed to withstand extreme temperatures while maintaining their structural integrity and providing effective insulation.They are widely used in industries such as metallurgy, petrochemicals, aerospace, and automotive, where high-temperature insulation and protection are critical.
