ICP Ceramic Tubes, manufactured from specially formulated ceramic bodies, are white and free of iron sulfide. Com-positions are available for special applications and tubes can be manufactured from ICP mullite, fireclay or fused silica. Any fractional length, or tubes longer than 12" (304 mm), can be produced upon request. The tubes are non-eroding, and assure a smooth slag-free passage of metal to mold cavity without contamination and without reaction with metal. Ends are precision-made for a sure fit. The tubes are available in a wide range of sizes: standard plain end, mitered and male-female ends.
