  • Projekt bioplynové stanice FLEXSTAR, Veigy-Foncenex, Francie, 2023 (anglicky)

    In the French twin municipality of Veigy-Foncenex, a reliable pipe system was to be laid for a biogas plant near Lake Geneva. The biogas site was founded five years ago, and a new building was added in 2023. A local heating pipeline with our FLEXSTAR UNO pipes was installed to ensure a flawless energy supply for the new part of the building. 

    Two rings of FLEXSTAR UNO, each 200 metres long, were supplied and laid for this construction project. The aim was to connect the pre-pit of the biogas plant with the boiler room. The construction work took a total of two months, whereby the actual laying of the pipes was completed within two days.  

    The most important construction stages were the construction of a new building and the laying of the pipes under the floor slab. In the first stage, the pipes were laid in the new building before the concrete slab was poured. The next stage involved laying the trench to the boiler room. Thanks to the good weather and the easy handling of the FLEXSTAR pipes, the installation was simple and uncomplicated. Now the biogas plant can supply the region even better with renewable energy in the future.

  • Projekt CALPEX Riehen, Fondation Beyeler, Švýcarsko, 2023 (anglicky)

    In the canton of Basel-Stadt, an efficient pipe was laid in the village of Riehen for the Fondation Beyeler, the internationally renowned museum of modern and contemporary art. Our best-insulated CALPEX pipe was used to supply the new museum building with district heating and cooling in the future.

    Construction work began in November 2023 and extended over three stages. A total CALPEX pipe length of approx. 800 metres was installed in the project. The aim of the work was to connect the new museum building with the pavilion and connect it to an existing district heating network. A special feature of the project was the production of a special part. This was a ventilation system, which was agreed with the customer before construction work began and installed accordingly. During the construction work, the customised part had to be slightly adjusted on site by the regional welder.

    One of the biggest challenges in the CALPEX project, in addition to the complex construction of the customised product, was the terrain next to the new museum building. In order to protect the large old trees, the pipes had to be laid carefully in the trench - which our fitters mastered in exemplary fashion.

  • Projekt CALPEX, Attiswill, Švýcarsko 2018


    V obci Attiswill v Bernu byly v topné síti propojeny tři bytové domy. Členové obce dodávají suroviny pro samotný systém ústředního vytápění – dřevo z nedalekého komunitního lesa.


    Vzhledem k tomu, ceremoniál k dokončení budovy byl na spadnutí, potrubí CALPEX muselo být položeno při teplotách kolem bodu mrazu. Další opatření, jako je předehřívání potrubí CALPEX, pomohlo zajistit, aby potrubí mohlo být instalováno bez problémů. Rolf Steffen, vedoucí týmu společnosti Alpiq AGje velmi spokojen. "Projekt ukázal, jak spolupráce mezi montážníkem, Meierem Toblerem a společností Brugg Rohrsystem AG fungovala od fáze plánování až po fázi realizace. Přesně takhle si představuji týmovou práci."

  • Projekt CASAFLEX/PREMANT síť dálkového vytápění Carona, Ticino, Švýcarsko, 2023 (anglicky)

    In Carona, a small village in the popular Swiss canton of Ticino, an extensive district heating pipeline was laid from the heating plant to the centre of the village. Our reliable PREMANT UNO and CASAFLEX DUO pipes were used to optimise the supply of heat energy to the residents.

    The main heating network for Carona was built twelve years ago. Over the years, it has been repeatedly extended and expanded. In the course of these expansions, the largest construction phase was completed in 2019. We laid an extensive district heating pipeline from the heating centre to the village centre. Our rigid PREMANT UNO pipe was used for the straight pipeline. The flexible and bendable CASAFLEX DUO pipe, on the other hand, was mainly used in the centre of the village.

    The biggest challenge on site was the limited space in the old town centre. As the streets were not passable by lorry, our fitters parked the lorry outside the village centre and then pulled the CASAFLEX pipe over the winding streets to the trench. The laying of the pipes themselves has been a complete success so far.

  • Projekt CASAFLEX/PREMANT topná síť Sachseln, Švýcarsko, 2023 (anglicky)

    In the diverse Swiss municipality of Sachseln, a district heating pipeline was laid near Lake Sarnersee for the local heating network. Our efficient CASAFLEX and PREMANT DUO pipes were used for the Flüelistrasse to ensure that the residents are supplied with sustainable energy in the future.  

    Construction work began in March 2023 and is still ongoing, as the construction project is part of a larger heating network. As a pipe constructor, we have already realised several projects for the customer together with the engineering office. The aim of this project was to connect Flüelistrasse to an existing district heating network. The energy released for the district heating pipeline is obtained from the combustion of wood chips. 

    As the Flüelistrasse connects the village of Sachseln with Flüeli-Ranft and the pilgrimage site there, it was important to minimise damage to the road. Our CASAFLEX and PREMANT DUO pipes have two inner pipes of the same size for the flow and return of thermal energy. As only one pipe was required per line instead of two, our fitters were efficient when laying the pipes. The biggest challenge in the construction project was installing the pipe at the Salzbrunnen bridge. Because the pipeline could not be installed above or below the bridge, it was necessary to attach it to the side of the Salzbrunnen bridge with special fastenings.

  • Projekt CASAFLEX/PREMANT Klausenstrasse, Bürglen, Švýcarsko, 2023 (anglicky)

    In the popular sports and recreation centre in Bürglen, a reliable and robust local heating pipeline from BRUGG Pipes was laid for Klausenstrasse for the local community. Our perfectly matched CASAFLEX and PREMANT pipes were used in this project to provide residents with a reliable supply of sustainable energy in the future.  

    Construction work began in March 2023 and lasted until July 2023. The aim was to lay a local heating pipeline for the school building and the surrounding residential buildings. The flexible CASAFLEX and the rigid PREMANT pipe system were used in several construction stages. In total, the fitters installed a route length of 400 metres during this construction phase. Approx. 1,700 metres are planned for the final expansion. 

    Important steps in this project included parking the lorry with the material, pulling and aligning the pipe in the trench and fitting the couplings. Our resistant PREMANT pipes were used for the transport line and the flexible CASAFLEX pipes were used for the house connections. A considerable challenge in the project was laying the pipeline from the power station up the steep mountainside to the main road. Despite the demanding gradient on site, our fitters mastered the individual construction stages with aplomb.

  • Projekt tepelné sítě CASAFLEX/PREMANT, Rothenthurm, Švýcarsko, 2023 (anglicky)

    In the foothills of the Swiss Alps, the municipality of Rothenthurm has decided to install a district heating pipeline. Many public and private buildings in the town are to be heated sustainably with a central heat source. Our compatible CASAFLEX and PREMANT pipes were used to provide the residents with an optimum energy supply in the future. 

    The construction project started in summer 2019 and involved laying a total length of up to six kilometres. Not only existing buildings, but also new flats will be connected to the heating network. Our rigid PREMANT pipes were used for long and straight sections. Flexible CASAFLEX pipes were used for the house connections.  

    In the first construction phase, the district heating pipeline was built from the new heating centre to the primary school building. The energy for the heating centre is supplied by an enormous wood boiler, in which heat is generated by burning wood chips and transported to the buildings through our pipes.  

    When carrying out the project, the trench along the roads had to be cleared in such a way that it caused as little disruption to road traffic as possible. Another challenge for the workers on the project was the electrical and water pipes already laid in the ground. The altitude of the construction site posed an additional challenge in winter, as the construction pits had to be kept clear of snow. 



  • Projekt FLEXWELL-FHK Tepelná síť Worblental, Bern, Švýcarsko, 2024 (anglicky)

    We have successfully completed the expansion of the district heating network for our customer EBL (Genossenschaft Elektra Baselland) in the Swiss capital of Bern. With our extremely heavy-duty FLEXWELL DHC district heating pipeline, we have completed a crucial construction phase. Namely the connection between the municipality of Ittigen and the city of Bern. Our pipes were laid under the River Aare to supply the Worblental heating network with sustainable heat in the future.

    The project began immediately after Easter with the delivery of two of our FLEXWELL DHC pipes in the largest available dimension DN 150, which weighed an impressive 7.5 tons per pipe. With a casing diameter of 310 millimetres, a pipe length of 226 meters each was transported to Bern on two drums. Thanks to the use of a special transport with extra width, the pipes were also transported over narrow stretches of land.

    The construction site was managed thanks to the use of heavy machinery and six experienced fitters. A special mobile crane with a lifting capacity of 130 tons was used to unload the pipes. Another 60-tonne pneumatic crane lifted the drums into the pipe-laying trolley. Two of the FLEXWELL DHC district heating pipes were pulled from the starting trench on Arastrasse in Ittigen into the empty pipes and laid from there under the river up to Tiefenaustrasse in Bern using cable winches.

  • Projekt FLEXWELL-DHC Moosstrasse, Lengnau, Švýcarsko, 2023 (anglicky)

    The Burgergemeinde and the municipality of Lengnau in the Swiss canton of Bern are focussing on ecological and economical heating with their joint heating network called WärmeLengnau - with the aim of producing heat sustainably. Our durable FLEXWELL DHC steel casing pipe system was used in Moosstrasse to ensure that the town is optimally supplied with heat energy. 

    Since 2020, many new district heating pipes from BRUGG Pipes have already been reliably laid for the construction projects of the heating network in Lengnau. In September 2023, a district heating pipe was installed in Moosstrasse as part of these construction projects. The aim was to connect the flexible steel casing pipe to an existing heating centre in the shortest possible time so that public traffic was affected as little as possible. 

    The short time frame was a considerable challenge for our fitters on site, especially as a total of two FLEXWELL DHC pipes, each 134 metres long, were to be laid. Due to the time constraints, our workers had to unwind the pipes from the reel, straighten them, pull them into the trench and align them particularly quickly and efficiently. As the trench was very close to the road, it was also important to work extremely carefully within the cordoned-off areas when laying the pipes. Another challenge was finding the space for the bogie and ensuring access for the lorry with the drum. Despite the challenges, the installation went smoothly thanks to the hard work of our fitters.

  • Projekt FLEXWELL-DHC Nürenbergstrasse, Curych, Švýcarsko, 2023 (anglicky)

    In Zurich, the city with the highest population in Switzerland, a flexible and resistant district heating pipe from BRUGG Pipes was laid for Nürenbergstrasse under narrow conditions. Our FLEXWELL DHC steel casing pipe system was used to provide the residents of the building block with an optimum and sustainable supply of heat. 

    The construction project began in September 2023. The aim was to connect the flexible steel casing pipe to an existing pipeline and connect it to the building. The construction work took just three days, with the most important steps being the challenging pulling of the pipe into the trench and the pipe laying itself. Two FLEXWELL DHC pipes were used for this project. As the trench was close to a garden plot, it was important to lay the pipe extremely carefully. 

    At the construction site, there was hardly any parking space on Nürenbergstrasse for the lorry carrying the material, which is why the workers parked the lorry on the other road and then pulled the pipe across a green area to the trench. Another challenge was that no tractor unit could be used for digging. The fitters on site therefore worked increasingly with deflection pulleys to align the pipes underground and master the narrow bends - which they did perfectly.

  • Projekt FLEXWELL-DHC Muzeum dopravy v Luzernu, Švýcarsko, 2022 (anglicky)

    Insulated pipe systems at the Swiss Museum of Transport
    At Switzerland’s largest and most famous museum – the Swiss Museum of Transport located directly on Lake Lucerne – BRUGG Pipes collaborated on an amazing project together with Energie Wasser Luzern (ewl) in March 2022. The district heating and cooling lines connect the new energy centre of the new “House of Energy” multi-purpose building to the existing exhibition buildings through the outdoor area.

    Use of lake water as a modern and ecological source of heating and cooling in Lucerne.
    The system is located in the outdoor area of the museum, which is also open to visitors, so fast and efficient execution of the project was of utmost importance and central for all involved parties. Thanks to detailed project planning and coordination, the project went smoothly and was completed on schedule. Installation was carried out by our own installation team to the complete satisfaction of the customer.

    A special feature of this project was that the lake water in the immediate vicinity was used as an energy source and distributed with a heat pump. The lake has large heat and cold reserves that can be used ecologically. This is an inexpensive and renewable source of energy with low investment costs and low maintenance. Thanks to the energy from the lake, the use of fossil fuels can be greatly reduced, thereby minimising CO2 emissions. Since the energy is produced locally, long transport routes are not necessary and the added value stays in the region

  • Projekt PREMANT DN 350, Sion, Švýcarsko (německy)

    Project CH-Sion  - 21 km PREMANT DN 350 Pipe





  • PREMANT project, Pláž Baltského moře, Heiligendamm, Německo 2017

    Dálkové vytápění na pláži Baltského moře

    Nápadné bílé budovy podél pláže Baltského moře jsou to, co dává Heiligendamm svou přezdívku "bílé město u moře". "Řetězec perel" bílých budov dodává od roku 2017 nově položená linka dálkového vytápění. Běží zde staré i nové vedení dálkového vytápění, do kterého bylo investováno celkem 1,1 milionu eur. Trubka PSP DN 200 byla připojena ke stávajícímu předizolovanému potrubí DN 250 v blízkosti kolejí úzkorozchodné železnice Molli. Německé trubky PREMANT trubky a prefabrikovamé díly byly dodány a položeny na délku kolem 250 m.

    Jako obvykle, bylo nutné přejít některé další sítě. Z hlediska statiky byla trubka projektována pro 16 bar. Bylo poměrně snadné umístit vypočítané U a Z kompenzátory podél Kühlungsborner Straße. Vyrobeno z 1 x 2 m kolen, nebyly vyžadovány žádné spojky. PREMANT a FLEXWELL

    Tato situace se změnila mezi lázeňskou budovou a Grand Hotelem. Plochy mezi přilehlými budovami a cestami byly úzké a byla vyžadována jiná metoda. Voda, která je až 110 °C, zde teče v hloubce až 4 m. S kabelem dálkového vytápění BRUGG DHC by tato část mohla být dokončena pomocí směrového vrtání a bez nutnosti vykopávat cesty, parkovací plochy a trávníky. Přechod z PREMANT na FLEXWELL je zde klíčový. V důsledku vnitřního tlaku 16 bar je expanzní síla na koncích cca 45 kN. Pro absorpci tohoto napětí byly staticky měřeny následné trubky PREMANT a prefabrikované díly.

    Část síly je absorbována povrchovým třením, které činí přibližně 4 kN/m. Většina napětí je však dosažena bočním stlačením kolen PSP proti zemi. Ocelové pouzdro kabelu dálkového vytápění FLEXWELL je také užitečné, protože aplikuje nebo přenáší část napětí. Třetí a čtvrtá etapa výstavby vedla z Vily Perle, která byla kompletně zrekonstruována v roce 2013, až po hotel Residenz. Dalších 600 m trubek FLEXWELL 200/310 bylo pohřbeno, přerušeno pouze spojovacími body a křižovatkami. Potrubí bylo odstaveno, aby se navázalo spojení se stávajícím potrubím PSP. Pro umožnění následného opětovného připojení je k dispozici šest kulových ventilů na ploše pouhých 20 m². "FWN-Aufrüstung Heiligendamm – 1. bis 4. PROJEKT BA " (Modernizace dálkového vytápění Heiligendamm – fáze výstavby 1 až 4) ukazuje, jak lze vytvořit optimální linku díky chytrému plánovacímu řešení kombinace tuhých a flexibilních potrubních systémů. Německý kanál zkompiloval statické výpočty. Teplota průtoku: 110°C

Potrubní system ocel v oceli

  • Projek systému „Ocel v oceli“ jako parní potrubí v Luterbachu, Švýcarsko


    Mezi spalovnou a papírnou byla instalována parní trubka. Z vizuálních důvodů nemohlo být potrubí o délce 836 m umístěno nad zem a nadzemní potrubí nemohlo být položeno do země. Bylo zapotřebí řešení. Požadavek: 220°C provozní teplota DN 500, výkon 45 tun/hod


    Byla položena trubky „ocel v oceli“. Flexwell DN 100 z oceli 1.4404 byl použit pro vratku kondenzátu. Pro úsek 836 m byly z větší části použity 12 m díly. Pro změny směru byly vyžadovány speciální díly. Ohebná kondenzátová trubka DN 100 mohla být položena v jednom kuse mezi šachtami.
