A BRUGG GROUP COMPANY
Project
BRUGG Pipes is laying EIGERFLEX LONGLINE UNO 50/111 in Switzerland – 474 meters in one piece.
The above-ground installation of this innovative pipe system provides an efficient and reliable solution that has been specifically tailored to the requirements of the project. The aim was to create a continuous cold water pipe that reliably protects the medium from frost thanks to integrated heating technology.
Implementation
The project involved the above-ground installation of EIGERFLEX LONGLINE over an impressive length of almost 500 meters. The flexible and robust design of the pipe system made it easy to handle and install, even in challenging terrain.
Thanks to its excellent insulating properties and integrated frost protection heating technology, the pipe provides a safe and sustainable solution for the cold water supply at altitudes of up to 1,000 meters.
The work was planned with precision and executed with the utmost care to meet the customer's high quality standards. Despite challenging conditions on site, the installation was completed smoothly and on schedule. The EIGERFLEX solution provides a long-lasting, reliable and economical infrastructure that performs well even under extreme conditions.
Project
Close to Austria's oldest glacier ski area, a wastewater pipeline was to be installed from the mountain station to the middle valley station of the gondola lift on the Kitzsteinhorn and integrated into an existing pipeline from the middle to the valley station. Our high-quality EIGERFLEX LONGLINE pipes were used to provide optimum frost protection for the water.
Realization
Two EIGERFLEX LONGLINE pipes, each 390 m long, from BRUGG Pipes were used at an altitude of up to 3,000 meters. This demanding installation was carried out in close cooperation with our proven distribution partner KE KELIT and its customers.
The challenges that the workers had to face at this altitude were not limited to the technical implementation, but also included the logistical feat of transporting the material and vehicles over narrow mountain roads to the installation site at an altitude of over 3,000 meters. As the trench was not located directly in the glacier area, but in rocky scree, it first had to be cleared by blasting and drilling. The entire project was heavily dependent on weather conditions and it was essential to keep the trench clear of snow to ensure a flawless technical installation. The construction work was carried out in two phases and lasted from June to October 2023.
Project
In the Pinzgau region of the state of Salzburg, two cable lifts recently opened on the Kitzsteinhorn at 3203 metres above sea level. Our pre-insulated EIGERFLEX pipe system is used as a frost-proof drinking water and sewage pipe to connect the intermediate station 200 metres below to supply the top station (2650 metres above sea level).
Challenge
A 1250-metre-long trench was dug in the rocky terrain to lay the EIGERFLEX pipe system. In order to guarantee operation during ski season, frost resistance must be ensured at any price in this rough climate. We met this requirement by applying single-phase fixed resistor heating tapes, which enable heating circuit lengths of up to 1000 m. It was possible to implement the two pipe systems with just two power inputs each, much to the delight of those responsible for the project.
