Pipe Relining – small and precise
The pipe relining procedure (pipe run, long pipe and short pipe relining) can be used in the sector of gas, water and wastewater pipelines as well as in industrial pipelines for almost any kind of damage, wherever a reduction of the cross section of the existing pipeline is possible. Against a new pipe, the pipe relining creates a new fully functional pipeline in the cross section of the existing pipe.
For the relining of pipe runs, the pipes are first welded together to a run and then they are inserted as a whole, whereas in the long pipe relining the pipes are welded in the insertion pit and successively installed and in the short pipe relining, (only pressureless sector) short pipe modules are entered one by one through the existing shafts into the pipeline to be rehabilitated.
After the insertion of the inliner, the remaining ring gap can be backfilled. This filling material provides a fixing of the inliner as well as a defined embedding, a uniform transmission of the outer loads and the prevention of dangerous gas bubbles.
The new pipeline has a sufficient static bearing capacity, good hydraulic properties, tightness, pressure strength and resistance to corrosion.
