  • FLEXSTAR-projektin biokaasulaitos, Veigy-Foncenex, Ranska, 2023 (englanti)

    Project
    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. 

    Execution
    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.

CALPEX PUR-KING

  • CALPEX-projekti Riehen, Fondation Beyeler, Sveitsi, 2023 (englanti)

    Project
    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.

    Execution
    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.

  • CALPEX-projekti Attiswil Sveitsi 2018

    Projekti

    Attiswilin kunnassa Bernin lähellä 3 kerrostaloa yhdistetään yhdeksi lämpöverkoksi. Raaka-aineen keskitettyyn lämmitysjärjestelmään toimittavat itse kuntayhteisön jäsenet – he käyttävät lähimetsien puuta.


    Haaste

    Talon lähestyvien harjannostajaisten takia CALPEX-putki pitää asentaa nollakelillä. CALPEX-putken esilämmittämisen kaltaisilla lisätoimenpiteillä asennus saatiin suoritettua ongelmitta. Alpiq AG:n tiiminvetäjä Rolf Steffen on CALPEX-putken onnistuneen asennuksen jäljiltä erittäin tyytyväinen. ”Projekti osoitti, kuinka hyvin yhteistyö putkiasentajien, Meier Tobler -yhtiön ja Brugg Rohrsystem AG:n välillä toimi projektivaiheesta toteutukseen asti. Juuri tällaista kunnon tiimityön pitääkin mielestäni olla.”

CASAFLEX

  • CASAFLEX/PREMANT-hankkeen kaukolämpöverkko Carona, Ticino, Sveitsi, 2023 (englanti)

    Project
    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.

    Execution
    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.

  • CASAFLEX/PREMANT-projekti lämmitysverkko Sachseln, Sveitsi, 2023 (englanti)

    Project 
    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.  

    Execution 
    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.

  • CASAFLEX/PREMANT-hanke Klausenstrasse, Bürglen, Sveitsi 2023 (englanti)

    Project 
    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.  

    Realisation 
    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.

  • CASAFLEX/PREMANT-hankkeen lämmitysverkko, Rothenthurm, Sveitsi, 2023 (englanti)

    Project 
    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. 

    Realisation 
    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. 

     


FLEXWELL-FHK

  • FLEXWELL-FHK -hanke Moosstrasse, Lengnau, Sveitsi, 2023 (englanti)

    Project 
    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. 

    Execution
    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.

  • FLEXWELL-FHK-hanke Nürenbergstrasse, Zürich, Sveitsi, 2023 (englanti)

    Project 
    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. 

    Execution 
    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.

  • FLEXWELL-FHK-projekti Verkehrshaus Lucerne, Sveitsi, maaliskuu 2022 (englanti)

    Project
    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.

    Execution
    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

  • PREMANT-projekti Itämeren rannikolla, Heiligendamm, Saksa, 2017

    Kaukolämpöä Itämeren rannalle
    Itämeren rannalla kohoavat näyttävät valkoiset rakennukset ovat tuoneet Heiligendammille epiteetin ”Valkoinen kaupunki meren rannalla”. Valkoisten rakennusten muodostama ”helminauha” on saanut lämpönsä vuodesta 2017 vasta-asennetun kaukolämpöputken toimittamana. Täällä kulkee vanhoja ja uusia kaukolämmön syöttöputkia, joihin on investoitu yhteensä 1,1 miljoonaa euroa. Lähellä Molli-kylpyläradan kiskoja muovivaippaputki DN 200 liitettiin valmiiksi paikalla olleeseen DN 250 -muovivaippaputkeen. German Pipe toimitti ja asensi PREMANT-putkia ja muotokappaleita noin 250 metrin pituudelta.


    Kuten tavallista, linjat ristesivät muutaman muun syöttöjohdon kanssa. Staattisen mitoituksen perusteella paineen arvoksi tuli 16 bar. Kühlungsborner-kadulla U- ja Z-laajennukset saatiin sijoiteltua suhteellisen mukavasti. 1 x 2 m:n kulmapaloilla asennusmuhveja ei tarvittu. PREMANT ja FLEXWELL Kylpylärakennuksen ja Grand Hotelin välillä tilanne muuttui. Työmaata rajaavat rakennukset ja tiet olivat lähempänä, ja käytettäviä menetelmiä piti rukata. Täällä jopa 110 °C:n lämpöinen vesi kulkee jopa neljän metrin syvyydessä. BRUGGin FHK-kaukolämpöputki mahdollisti tämän osuuden valmistuksen vaakaporauksella teitä, puistoalueita ja niittyjä kääntämättä. Tässä kohdin siirtymä PREMANTista FLEXWELLiin on olennaista. 16 barin sisäpaine aiheuttaa päissä noin 45 kN:n venytysvoiman. Jotta järjestelmä kestäisi tämän kuorman, liittyville PREMANT-putkille ja -muotokappaleille suoritettiin staattinen mittaus.

    Osan voimasta kumoaa vaippakitka, jonka suuruus on noin 4 kN/m. Suurin osa vastavoimasta perustuu kuitenkin muovivaippaputken kulmakappaleiden sivuttaiseen puristumiseen maaperää vasten. Apua tässä on myös FLEXWELL-kaukolämpöputken teräsvaipasta, joka luo ja siirtää osan vastavoimasta. Rakennusvaiheet 3 ja 4 kulkivat vuonna 2013 täydellisesti kunnostetusta Villa Perlestä asuntohotellin taakse. Maahan asennettiin vain liitoskohtien ja luistiventtiilien katkaisemat 600 lisämetriä FLEXWELL 200/310 -putkea. Liitäntä valmiiseen muovivaippaputkeen valmistettiin suluilla. Myöhemmän vaihtokytkennän mahdollistamiseksi 20m²:n alueelle asennettiin peräti 6 palloventtiiliä. ”Heiligendammin kaukolämpöverkon päivitys, rakennusvaiheet 1–4” – (projektin virallinen nimi) osoittaa, kuinka optimaalinen linja voidaan luoda taitavasti suunnitellulla jäykkien ja joustavien putkistojen yhdistelyllä. Staattiset laskelmat laati German Pipe. Virtauslämpötila: 110 °C Nimellispaine: PN 16

Teräsvaippaputkisto

  • Teräsvaippaputkistoprojekti höyryputkena, Luterbach, Sveitsi

    Tehtävä:
    Jätteenpolttolaitoksen ja paperitehtaan välille rakennettiin höyryputki. 836 metrin pituisen välikappaleen maanpäällinen asentaminen ei tullut maisemallisista syistä kyseeseen. Käytettävissä ollutta maanpäällistä putkea ei voinut asentaa maaperään. Tarvittiin ratkaisua. Vaatimus: 220 °C:n käyttölämpötila DN 500, siirtomäärä 45 tonnia tunnissa
     
    Ratkaisu:
    Asennettiin teräsvaippaputki. Lauhteen paluuputkena toimii Flexwell DN 100 teräksen materiaalinumerolla 1.4404. 836 metrin pätkä koottiin enimmäkseen 12 metrin osista. Erikoisosia tarvittiin suunnanmuutoksiin. Joustava lauhdeputki DN 100 saatiin asennettua yhtenä kappaleena kaivojen välille.
