Translation of "Rohrsanierung" in English

Pipe reconstruction from the inside is the most cost-effective alternative to expensive and complex re-installation.

We lead you safely into the high-tech world of trenchless pipe rehabilitation.

We have made a name for ourselves throughout Europe with trenchless pipe rehabilitation.

The reduction process was originally developed for the rehabilitation of pressure pipelines in the wastewater, drinking water and gas sectors.

Long-term rehabilitation of ovoid pipes has thus certainly become one of the special challenges in sewer rehabilitation.

The reduction process was developed for the rehabilitation of pressure pipelines in the wastewater, drinking water and gas sectors.

Eventually, a highly schematic and simplified representation provides all relevant information which is required by the operator for performing for example a pipe repair.

In particular, it is very advantageous for pipe rehabilitation if at least one inner barrier layer against the passage of gases and/or chemical substances is provided, whereas the barrier layer preferably contains ethylene vinyl alcohol (EVOH) or polyamide (PA) or cyclic olefin copolymers (COC) or a combination of these, preferentially each with up to 100% by weight made of such compounds.

The lighting device and use according to the invention, for example in the field of duct and pipe relining, offer the advantage of high radiation intensities having high homogeneity of the radiation distribution and at the same time good bendability of small pipes even in 90° bends.

If the multilayer film is used for pipe renovation, the polyamide layer is bonded to a fibrous nonwoven by heating, and this is then saturated with a hardenable resin.

The internally situated tube of this type of insertion tube, or a corresponding multilayer film, preferably in the form of a tube, used for pipe renovation and as disclosed by way of example in EP-A-0 342 897, is subject to stringent mechanical requirements, in order that it can withstand loads arising during its handling, for example those occurring during introduction into the pipe requiring renovation, during the inflation of the respective film within the pipe, or—after successful renovation—during removal from the pipe.

It was therefore an object of the present invention to provide a multilayer film, in particular in the form of a tubular film, which is suitable as internally situated tube of an insertion tube for the renovation of subterranean pipes, preferably subterranean sewer pipes, since it has not only the necessary permeability to UV radiation but also mechanical properties that are sufficiently good for it to withstand the high loads that arise during pipe renovation.

With the following links, we want to recommend to you some interesting websites of companies with whom we work together and to refer you to websites where you can find further valuable information about sewer rehabilitation!

The Japanese group SEKISUI Chemical has restructured its pipeline renewal business in Europe by way of a management buy-out.

To do so, the operator decided for a pipe rehabilitation in pipe-lining technique after taking all conditions into consideration and also in light of the urgency of the project.

Application technician Sven Menzel at sewer maintenance company GM-San UG has tested the “new” robot and has gained some early experience of working with it in sewer maintenance work.

We will gladly advise you on issues of No-Dig pipe rehabilitation and present our solutions for defective pipes inside buildings.

Due to the ongoing consolidation and diversification of the group of companies, it is structured in three holding companies in accordance with their different service areas (construction, project development, pipe rehabilitation, technology, building materials and services) and the the resulting allocation of the individual companies.

With the REHAU systems for trenchless pipe renovation and new installations, you have a professional solution at hand for a variety of application areas and installation types.

In recent years, a lot of old water pipe renovation fever, and gas pipe was to scrap (good case).

In underground pipe renewal, the winch may be used for pulling and positioning measuring instruments or cameras or for pulling heavy winch ropes into pipes.
