Sea outfall project in Stockholm, Sweden

Sea Outfall project in diameter DN/ID3400mm and DN/ID1400mm
for a power plant in Stockholm, Sweden

For a power plant in the capitol of Sweden a sea-outfall pipe was planned originally in concrete. The construction-site is located directly at the ferry-harbour in Stockholm.

Because of the impressive product-properties and the professional design the German Henze GmbH convinced the client to use a helical extruded polyethylene pipe with the diameter DN/ID 3400 mm. As part of the overall project also a provisional pipeline DN/ID 1400 mm was necessary for crossing a brackish water basin.

The DN/ID 3400 mm pipes are designed with a strong solid wall part and a reinforced profiled wall structure, so that the total wall thickness reached 180 mm and the outer diameter was ca. 3760 mm. The profiled wall is specially designed for filling with concrete during installation at site. The additional ballast ensures that the pipe-system can be launched and submerged in a safe and easy way. Also the DN/ID 1400 mm pipes are designed similar to a wall structure - with a strong solid wall part and a reinforced profiled wall structure.  

The complete project covers around 135 m of DN/ID 3400 mm pipe and furthermore 100 m of DN/ID 1400 mm.
