The steel bifurcation pipe with a design internal water pressure of 6.83 MPa and HD value of 4084 m2 in the CCS Hydropower Station Project in Ecuador is designed according to the American standard ASME 79, and the Japanese steel material is adopted.Based on the preliminary design of bifurcation profile, a three-dimensional finite element mod-el of the bifurcation pipe is built and a structure analysis is carried out.In addition, numerical simulations of the typical hydraulic conditions are performed.Accordingly, optimization suggestions on the profile design and operation of units are proposed.
