  • a particular advantage is also the absolute corrosion resistance of the pipe system.
  • an existing main pipe acts as a kind of anchor point or as an abutment for an optimal contact pressure of the branching element to be welded.
  • defined conditions can be provided or favorable force introductions can be ensured.

  • the object of the invention is also achieved by a tensioning and lifting device according to the features of claim 11.
  • An advantage of the design according to the invention is that such a tensioning and lifting device can be used several times and thus an optimized cost-to-power ratio can be created. But also by the multiple functionality of the clamping and lifting device, in particular in its function as a lifting tool and in its additional function as a clamping tool against a main pipe, the economy of the overall system can be favored. Above all, through the use of at least one tensioning strap, a process-reliable and intuitively operated tensioning device can be provided beyond that to the respective assembly personnel. Among other things, by the formation of a pressure distribution plate undesirable deformations of the thermoplastic, softened in the course of a welding process branch element, in particular of its Aufsetzsattel, can be further avoided or refrained.
  • the tensioning and lifting device enables the creation of a high quality and at the same time buildable connection between a branch element and a main pipe.

  • this can result in an oblique-angled or quasi-one-sided elevation of a branching element fastened to the tensioning and lifting device, without the risk of a mechanical coupling failing.
  • an inclined attachment of the branch element to a horizontally or approximately horizontally extending main tube can thus be carried out in a simple manner, as is frequently required, in particular, in the case of already existing channel systems or pipe systems.

In particular, a relatively low mass of the individual components can thereby be ensured despite relatively high deformation stabilities.
  • the measures according to claim 17 are also advantageous, as this provides several components which can be joined together to form the corresponding tensioning and lifting device. This facilitates the handling of the individual components and, moreover, a particularly warp-resistant or bending-resistant construction can be created.

  • the object of the invention is further achieved by a tubular branching element according to the features of claim 18. Due to the stated construction, a process-reliable, thermoplastic welding of the branch element with respect to a thermoplastic main pipe can be achieved. In particular, thereby defined contact forces can be generated, which are essential for a high-quality thermoplastic compound of said components. In addition, any overstressing or deformation of the branch pipe piece in its softened state, in particular during the welding process, can be obstructed by the corresponding shaping of the branching element. The same applies in this context for the main pipe. Also, the extension of the branch pipe piece to a far-reaching branch pipe can be made in a simple manner by the known extension or coupling methods.
  • relatively heavy-weight deflection elements can also be reliably offset, in particular raised, and positioned on a corresponding main tube.
  • the corresponding mechanical coupling can be easily and reliably constructed without the risk of incorrect implementation.
  • the production of the corresponding recesses or depressions is rational and economically feasible.
  • a corresponding positive coupling means can be constructed particularly economically and efficiently.
  • Asymmetric pressure loads, which could affect the assembly process are excluded by the measure according to claim 22.
