Yes, that’s possible! RTi is THE specialist for trenchless rehabilitation and inspection of pressure pipelines – and has been for over 30 years!
TIMELY REHABILITATION AVOIDS UNNECESSARY COSTS
It is not uncommon for pipes to burst, especially if they are older. Especially in the case of pressure pipelines, this can have devastating effects.
According to the Federal Ministry of Agriculture, Regions and Tourism’s Water Management Measures Report, about one third of the public drinking water pipelines in Austria – that is about 26,000 km – are older than 50 years. Maintaining this aging infrastructure is a major challenge for operators.
Timely rehabilitation is essential to avoid fractures and the associated costs. The solution? Trenchless pipe rehabilitation technologies
AN EXCELLENT ALTERNATIVE TO OPEN CONSTRUCTION – HIGHLY EFFICIENT AND ENVIRONMENTALLY FRIENDLY
There are a variety of different procedures and methods that can be used to rehabilitate pipelines that don’t require excavation. These trenchless technologies are an excellent alternative to traditional open trench construction.
What makes these environmentally friendly and highly efficient method so special is the fact that work can be carried out with little or almost no earthworks involved. On average, about 100 m of pipeline can be rehabilitated in one day. This results in enormous time savings compared to conventional replacement by means of excavation.
Reduced noise and dust pollution, protection of the above-ground and underground infrastructure, greatly reduced transport volumes and the associated reduction in CO2 emissions are additional advantages that distinguish trenchless pipe rehabilitation. In addition to the environmental benefits, these methods are usually a lot more cost-efficient than the open construction method.
RTi – THE SPECIALIST FOR PRESSURE PIPES
For over 30 years, RTi Austria has been involved in the trenchless rehabilitation of all types of pipeline networks. In addition to the rehabilitation open conventional channels, the Austrian pipe rehabilitation specialist has been particularly able to demonstrate its skills and knowledge in difficult industrial and pressure pipeline projects spanning the last few decades.
The many years of experience of the RTi team and the numerous projects that have been carried out make the company an absolute specialist in pressure line pipe.
RTi not only scores points in trenchless pipe rehabilitation, but also in the inspection of pressure pipes. RTi carries out well inspections up to a depth of 300 m and leak tests with pressures up to 200 bar.
TRENCHLESS PIPE REHABILITATION IN PRACTICE
RTi uses various technologies to rehabilitate pipelines, with pipe lining being its main rehabilitation technology.
In the pipe lining process, a liner impregnated with special resins is pulled or inverted into the old pipe. The resin is then cured thermally or using UV light.
In addition to a strong presence in Austria and Germany, RTi repeatedly focuses on international projects. The processes are regularly used for dimensions ranging from DN 150 – 1200 mm in Italy, Norway, the Czech Republic, Slovakia, Romania, Poland and Germany, among others.
