Abstract
A pipe connecting element serves to connect pipes, which consist essentially of a continuous inner pipe and connected with it, extending radially outwards, projections, which serve to stiffen the pipe. To make such a pipe connecting element suitable to the light construction concept of double walled pipes or corrugated pipes on the one hand and achieve high load capacity in the direction of the pipe axis and good hydraulic properties on the other, the pipe connecting element consists of connected with each other sections, which are constructed by a core pipe and a jacket pipe. Adjacent sections are connected on their butt joint surfaces in such a manner that the core pipes and the jacket pipes each of these adjacent sections are connected with each other. Additionally, the core pipe and the jacket pipe of each section are firmly connected with each other.
