  • 176900 Nord Stream Pipeline Vyborg (RU) - Greifswald (GER)

176900 Nord Stream Pipeline Vyborg (RU) - Greifswald (GER)

Industry: Pipeline
Project / Location: North Stream Pipeline Vyborg (RU) - Greifswald (GER)
Country: Russia
Customer: Gazprom UHDE
Year: 2011

Nord-Stream is the name of the 1224 km long natural gas pipeline through the Baltic Sea from Vyborg in Russia to Lubmin near Greifswald in Germany. The "Gas-In-Unit" from Uhde, equipped with two Thielmann waterbath heaters, was successfully commissioned in September 2011 and September 2012 (pipeline strings 1 + 2).

The Russian Prime Minister Mr. Putin and the Chairman of the Supervisory Board of Nord Stream AG and former German Chancellor Gerhard Schröder inspected the commissioning of the gas-in unit and the waterbath heaters.

Thielmann Energietechnik GmbH delivered two 4 MW water bath heaters designed for 220 bar (approx. 35 t per heater without skid) in just five months. When the pipeline is first filled, the gas temperature drops due to the resulting pressure reduction (Joule-Thomson effect) when the "gas tap" is opened. The heaters counteract this effect by warming up the gas and support the pressure build-up during the "gas-in" process in the "new" pipeline.
