Hamburg Eurogate - district heating connection pipe
Design & build contract for the expansion of the Eurogate thermal network, including specialized DN 1200 pipe jacking and high-pressure district heating integration under live operational conditions.
Main services
The expansion of the thermal energy network at Hamburg Eurogate represents a major utility project designed to enhance the region's heating capacity. The main services for this development focus on the high-precision laying and manufacturing of a district heating connection pipe, utilizing plastic-coated pipe (PMR) DN 200–300 with a robust nominal pressure rating of 25 bar.
Requirements
Executing a project of this scale requires a massive logistical and civil engineering effort to meet all site requirements. The scope of work involves a significant earthmoving operation, including the excavation and backfilling of 3,000 m³ of soil, alongside the professional restoration of 2,000 m³ of paved and asphalt surfaces.
A critical component of the underground installation is the 60-meter pipe jacking DN 1200, a trenchless technology that allows for large-diameter casing installation without surface disruption. The core mechanical work involves the expert welding and laying of 2,100 meters of plastic-coated pipe (DN 200-300 / 344-450). To ensure network control and regional integration, the project includes the manufacture of one DN 300 valve station and the successful completion of 4 building connections to the local grid.
Technical services
A standout technical feature of the Hamburg Eurogate project is the specialized drilling (stop-line) and connection of the new infrastructure to an operational district heating pipe (DN 300, PN 25).
- By utilizing "stop-line" technology, our engineering team can perform complex branch connections on a live system, ensuring that existing heat consumers experience no service interruptions while the new DN 300 connection is integrated.
