Abstract
546,247. Pipe joints. PRODORTTE, Ltd., and BURTON, W. A. Jan. 2, 1941, No. 85. [Class 99 (i)] [Also in Group V] A spigot-and-socket joint for pipes for conveying acid effluents or other hot chemicals is sealed by a packing of hemp, asbestos &c. behind which is poured, rammed, or trowelled, a resilient cement. The resilient cement is composed of'a rubber latex, silicate of soda, and a cement powder, and may be as described in Specification 433,741, [Group V]. Several examples of compositions containing these constituents are described, as well as examples of the cement powder, which is composed of colloidal sulphur, zinc oxide, casein, rubber accelerators, sodium silicofluoride, calcium silicofluoride, borax, and silica ; or the cement powder may be merely a mixture of sodium silicofluoride and silicon. The outside of the pipe at the joint and the inside of the socket may be coated with sodium silicate or other adhesive solution. The packing-material may be soaked in a slurry of acid-resisting cement, for example as described in the above-mentioned Specification.
