Title: Thermoplastic pipe socket with sealing ring - formed by heated arbor, moulding sleeve, ring inserter and finishing ring
IPC: F16L47/00
Filed: 1978-12-12
Abstract: An end section of a thermoplastic pipe is heated until it becomes elastically deformable and it is then opened out by means of a forming arbor. A sealing ring is fitted in the expanded mouth of the pipe and the end is further formed, so that a coupling section with an annular groove enclosing the sealing ring results. The coupling section is cooled and the arbor is withdrawn leaving the sealing ring in the groove. The heated end section of the pipe is opened first of all into a socket with a diameter which increases in steps towards its free end. the pre-formed socket is partially cooled until it is no longer deformable, whilst the widened end section is maintained at a temperature at which t is still elastically deformable. The sealing ring is then inserted into the end section which is moulded around the ring to the final form. On cooling the end section to a point at which it is not deformable, the arbor is withdrawn. Used to produce a pipe coupling with a sealing ring which can be duplicated continuously. The annular ring has a high degree of accuracy of form and measurement, and the sealing ring has the optimal characteristics for ensuring a seal both radially and axially.
