Work Detail

General Construction Work For Pipelines – Connection Wv Fr West To Geothermal Energy Wv Tel-Aviv-Yafo. The District Heating Pipeline Along Tel-Aviv-Yafo-Allee Is Crucial For Connecting The Freiburg West Heating Network To The Future Geothermal Heat Supply. In This Construction Phase, The Existing District Heating Pipeline From The Intersection Of Tel-Aviv-Yafo-Allee / Adelheit-Steinmann-Straße Will Be Continued. The District Heating Pipeline Runs Along Tel-Aviv-Yafo-Allee To Opfinger Straße. In The Area Of ​​The Vag Premises, The District Heating Pipe Bends Onto The Vag Premises And Ends In The Area Of ​​The Access To The Vag On Opfinger Straße. A Total Of 730 M Of District Heating Pipe Must Be Built As A Single Pipe. The Main Part Of The Pipeline Is Made Of Dn300 As A Single Plastic Jacket Pipe (Kmr). The Majority Of The Pipeline Is Manufactured Using Insulation Series 3. The Nordic Leak Warning System Is Used. The Branch To The Vag Is Made Of Kmr Dn200.
