PROCESS FOR SOCKET-JOINING THERMOPLASTICS-COVERED HEATING PIPES USING A WELDING MIRROR

摘要

The invention relates to a process for producing a sleeve joint of plastic-coated pipelines, especially for remote heating, two PE half- pipe shells of the same diameter, wall thickness and tolerance as the PE coated pipe are welded to one another and to the coated pipes using hot-element butt-welding. This is possible since the dimensional conformity is ensured by the half shells of the welding machine and the bevel running in the same direction at an angle of 60 DEG allows the seam pressure to be applied that is required for welding. The seam pressure is one of the welding parameters which is specified for hot- element butt-welding and is applied to both the workpieces.
