SELF-SUPPORTING VERTICAL PIPE STRUCTURE OF CERAMIC MATERIAL

摘要

A self-supporting vertical pipe structure which is suspended by its upper end, for example a central discharge pipe of a cyclone, consisting of fireproof units engaging each other is characteristic in that the units (3-9) are I-shaped. This structure has a tensile strength which is three times that of the known structures and moreover there are numerous other advantages by the structure, among other things it is possible with two unit sizes to build up pipes of many different diameters.
