Manifold blocks are recently used to connect hydraulic components in a hydraulic system that has flow channel inside. They are useful in reducing the size and weight of hydraulic systems. This paper deals with solid manifold block and laminated manifold block as trip equipment with which the turbine of a thermal power or a nuclear power plant is equipped. They are different from machining. We investigate pressure drops of their pipe flow with computational fluid dynamics (CFD) and compare the two types. We devised the new technique of having included CFD in pipeline network calculation. The final purpose is to design a laminated manifold block as trip equipment with which reduction in size and weight or reduction in pressure drops is realized. The conclusions from the aforementioned results are as follows. First, Branch/junction model can be calculated by the new technique of having included CFD in pipeline network calculation. Second, we achieved designing of a laminated manifold block as trip equipment with which reduction in size and weight or reduction in pressure drops is realized.
