As part of the Sutjeska Hydroelectric Power Plant Project in Bosnia and Herzegovina, the installation of GRP pipes with a diameter of DN1200 and pressure classes ranging from PN6 to PN32 is progressing rapidly.
A total of 3 km of GRP pipelines will be installed in the project, where SUPERLIT’s high-strength and long-lasting pipes have been chosen to ensure top performance and reliability.
🌱 Once completed, this eco-friendly power plant will significantly contribute to the region’s energy supply and support sustainable development.
💧 With their DN1200 diameter, high-pressure resistance (PN6-PN32), and exceptional stiffness ratings (SN5000 and above), SUPERLIT GRP pipes continue to deliver outstanding performance in demanding hydropower applications.
🌍 Having left its mark on projects across five continents, SUPERLIT proudly continues to invest in the future with reliable and sustainable infrastructure solutions.
SUPERLIT is the only pipe manufacturer in Turkey capable of producing glassfiber reinforced polyester (GRP) pipes using three different technologies: 'Continuous Filament Winding', 'Centrifugal Casting', and 'Helical Filament Winding'.
