Pressure piping of hydro-power plants - Eurocode-conformal regulations in the Austrian National Annex of the EN 1993-4-3.

By implementation of the Eurocodes the part EN 1993-4-3 "Pipelines" has also been published. Its real status within the wide field of existing pipeline-standards for various applications needs closer explanation. In the ÖNORM B 1993-4, i.e. the Austrian National Annex of the above Eurocode, such a commentary is g iven as well as additional rules for pressure piping of hydro-power plants which so far were not covered by specific standardization. Although, presently restricted in application to power plants of limited magnitudes of internal pressure and pipe diameter the general concept and the background may be taken from this paper.
