Interpipe, a leading global producer of steel pipes and railway products, supplied 186 tons of steel casing pipes for a unique geothermally-heated mega-greenhouse project covering 18 ha in the East Styrian Basin, Austria.
The project encompasses drilling of the two deviated deep wells of 3,278.5 m and 3,300 m in the East Styrian Basin southeast of Bad Blumau, aimed at exploitation of thermal waters with a temperature of 125 degrees C. By relying on renewable energy, the facility aims to reduce import dependence and strengthen Austria’s domestic food supply.
To meet the conditions of the geo-pressured well, Interpipe manufactured intermediate casing pipes made from L80 steel grade. It demonstrated sufficient strength to withstand burst, collapse, and tensile stresses at this depth, maintaining stable mechanical properties at the target temperature.
Bartlomiej Kania, OCTG Sales Manager for Continental Europe at Interpipe, said: “Geothermal energy is becoming a key pillar of Europe’s energy transition, unlocking a significant technical potential of steel pipe manufacturers. Interpipe provides a comprehensive portfolio of OCTG seamless products, including proprietary premium connections specifically designed for geothermal applications. These include the UPJ-SP connection, compatible with API Buttress, and the UPJ-QR, “easy-to-run” connection. Both are available in a wide range of diameters to meet the requirements of the European geothermal market”. (Interpipe)
