Abstract
A method is described for producing a pipe end socket () made of thermoplastic material with a sealing ring () which engages in a form-fitting manner on the inside of the socket in a circumferential bead () and which comprises a sealing part () and a supporting part (), with the sealing ring () being introduced into a preformed bead region and is then tightly held in a form-fitting manner in the circumferential bead () by a final forming of the preformed bead region. In order to provide advantageous process conditions it is proposed that the pipe end socket () with the circumferential bead () is preformed at a deformation temperature corresponding at least to the softening temperature with an overdimension which allows an insertion of the sealing ring (), and after the cooling below the softening temperature and after inserting the sealing ring () said pipe end socket with the circumferential bead is pressed into the final shape by taking into account a cooling-induced shrinkage.
