Abstract

This paper deals with the common practice of selecting pipeline valve diameters smaller than that of the pipeline itself. The most economic design in such a case dependent on both the valve diameter selected and the design of the reducers connecting the valve to the pipeline. The head loss through valves and reducers is discussed together with the capitalization of energy cost. Assuming a power penalty of R3 000/kW over the life of a pipeline, diagrams are presented from which the most economical valve installation may be designed. Three valve types are covered. A design example Illustrates the proposed procedure.
