Abstract

1,184,550. Heat-insulated pipes. PARK SECTIONAL INSULATING CO. Ltd. 29 Sept., 1967 [8 Dec., 1966], No. 55053/66. Addition to 1,095,872. Heading F2P. [Also in Division F4] In a flue section 10 wherein an outer sleeve 15 surrounds an inner tubular liner 11, the space therebetween is filled with insulation comprising a layer 12 of sodium silicate crystallized into a cellular structure, a sheet of asbestos 13 and a fibrous mat 14 of e.g. mineral or glass wool, both being impregnated with sodium silicate. In forming the flue section 10 sodium silicate is sprayed on to the inner liner 11 and heated causing the sodium silicate to crystallize and form the layer 12. The impregnated asbestos sheet 13 and fibrous mat 14 are applied over the layer 12 together with the outer sleeve 15. The complete section is then heated to cure the sodium silicate. Each flue section has its inner liner projecting beyond the outer sleeve to form a spigot 16 which slots into a socket portion 17 of the adjacent flue section. The inner liner 11 is made from stainless steel, asbestos cement coated with vinyl, or glazed vitrified clay piping.
