Title: PROCESS FOR PRODUCING A HIGH-PRESSURE PIPE CONNECTION
Abstract:
Process for producing a high-pressure pipe connection. A process for producing a steel-free high-pressure pipe connection and pipe union is characterised, according to the invention, by the following process steps: (a) arranging a substantially sleeve-shaped heating device (3) having a plastic base body and integrated heat conductors on a support mandrel; (b) arranging in a substantially coaxial manner a substantially sleeve-shaped insert (2) made of a fibre-reinforced plastic material and coated inside and outside with an adhesive on the outside of the heating device (3), at a distance therefrom; (c) spray-coating the insert (2) previously mounted in step (b) with plastics, at the same time as a fusion-welded connection is formed with the fibre-reinforced plastic material of which the insert (2) is made and with the plastic base body of the heating device (3); and (d) removing the support mandrel.
