In Dresden we are currently laying for DREWAG – Stadtwerke Dresden GmbH District heating pipes DN 250 for supplying the district of Mickten.
Special challenges are the laying under the traffic junction of Leipziger Strasse, as above ground there is still car, tram and pedestrian traffic and the tight schedule associated with this. Ludwig Pfeiffer is responsible for lifting and welding (4h! per day) the pipes. Via a construction pit, 10m long pipes are lifted in piece by piece and pulled into the steel protective pipe via a rail system.
After the non-destructive weld seam inspection and the successful pressure test by DREWAG, the district heating pipeline can be insulated. In the late afternoon, the next pipeline sections are then lifted into the excavation pit.
The reason for the construction site is to connect even more areas from the districts of Mickten and Kaditz to the district heating network of DREWAG. Our experienced and motivated colleagues on site kept to the tight schedule and did an excellent job. We thank them for their commitment and dedication.
In the next construction phase, Ludwig Pfeiffer pipelines will be laid and connected in the underground district heating structure. DREWAG is investing over EUR 3 million in the electricity and district heating line.
