Abstract

859,954. Pipe joints. BRITISH INSULATED CALLENDER'S (SUBMARINE CABLES) Ltd. Dec. 8, 1958 [Dec. 9, 1957], No. 38201/57. Class 99(1). A pipe joint comprises an internal or external sleeve 3, coupling pipes 1, 2 wherein the contacting surface of the substantially rigid plastic pipe or sleeve is provided with a series of closely spaced annular grooves 5, 6, whose side walls are inclined to the pipe or sleeve axis, so that the bottom of each groove lies nearer the adjoining end of the pipe or sleeve than the open end of the groove, the grooves providing tongues whose tip diameter is an interference fit on the neighbouring surface of the joint. The rigid plastic may be high density polyethene or high impact polyvinyl chloride and a layer of soft rubber may be secured to either of the contacting surfaces. The ratio of the groove depth (measured in an inclined direction) to the axial length of the tongue may be greater than one. The product of the axial length of the tongues multiplied by the number of tongues can be equal to or greater that the wall thickness of the member in which the grooves are formed. A sealing ring, e.g. of neoprene may be applied between the abutting end faces of the pipes.
