The product
When laying gas and water pipes in accordance with DVGW Worksheet GW 320-1 (Edition 02/2009) "Renewal of gas and water pipes by pipe insertion or pipe insertion with annular space", a distinction is made between three methods: pipe string relining, long pipe relining and short pipe relining. According to the technical framework conditions of the respective process, pipes made of PE, GFK, PVC, steel or other materials such as cast iron are brought into the line to be rehabilitated. The selection of the process depends on the local conditions and the desired properties of the new pipeline.
The field of application
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.
