Numerical Calculation of the A6 Bifurcation in C3 Pipeline in HPP ,,Perućica"

Journal Title: Machine Design - Year 2018, Vol 10, Issue 1

Abstract

This paper presents the results of numerical calculation of A6 bifurcation of C3 pipeline at HPP “Perućica”, which was carried out during the summer of 2007 and spring of 2008, by the team of experts led by Dr. Milorad Miso Buric, a full professor of the Faculty of Mechanical Engineering in Podgorica and The head of the Centre for transport machines and metal constructions (CETIM). The calculations were obtained at the critical points of the internal wall of the bifurcation showing that the tension is greater than the boundary of the large elongations for Nioval 47 steel, so it was concluded that there had been cracks in these positions. Indeed, when the protective paint was removed from these places, a large number of cracks were discovered. These cracks were then tested by the Institute of Black Metallurgy from Niksic and The Institute performed its analysis. The aforementioned expert team gave a written recommendation to the management of HPP "Perućica" to perform a reconstruction of the bifurcation, emphasizing that the situation was very critical. In April 2016, Lahmeyer International GmbH, Germany, in its Study of measures and works during the Phase II of the reconstruction for HPP “Perucica”, explicitly required that the reconstruction of the A6 bifurcation be carried out, and that additional surveys include other parts of the pipeline.
