Abstract

1327441 Making pipe couplings RAYCHEM CORP 20 Aug 1970 [25 Aug 1969] 40138/70 Heading B3A [Also in Divisions B1 C2 and F2] A method of making a tubular coupling of a memory metal (as defined in the Specification) comprises deforming a hollow article made of memory metal at below the critical temperature. Secondary deformation may be given either by deforming below the critical temperature with a force greater than that necessary to impart maximum thermally recoverable deformation, or alternatively by heating to the critical temperature at least and restraining complete recovery by allowing the article to contract about an object having a dimension greater than that to which the article would have otherwise contracted. This object may be a keeper of the same material, of resilient material, of copper-beryllium and/or of a material having a netative coefficient of expansion. The article may be in the form of a coupling for pipes, and of such dimensions that upon heating to at least the critical temperature the coupling will contract and grip the ends of the pipes to be joined. (see Division F2). Such a coupling (see e.g. Fig. 1) may be made from stock by drilling a hole therein, turning and cutting off the blank. The tapered end portion 26 is formed on a lathe. The lathe taper attachment is then reset to make the radial cut 30. By repeating, a second taper and tooth (32) are formed. The process is repeated from the other end, and finally the central portion 24 is bored. Thereafter taper portions 14 and 16 may be formed on the outside. Before use the surfaces should be polished and de-burred, and the coupling should be annealed.
