Excerpt

In this paper the development and experiences made with the application of high strength steels for penstocks and steel lined shafts for stored and pumping stored hydropower plants is discussed. The evaluation of failure cases showed that high strength steels have to be treated very carefully to assure safe fabrication and service conditions. The results out of those experiences have been introduced in qualification programs which leaded to measures to be applied to allow safe design, manufacturing and service behaviour under static as well as dynamic loading conditions of the conduits. …
