Pipeline design, the choice of what kind of pipe diameter is involves the terminal investment, operation cost and maintenance cost, prehensive analysis and study is needed to make a more correct choice. So choose pipe diameter usually can do more economic and reasonable, so called economic pipe diameter, the diameter corresponding to the diameter of the puting velocity is called economic velocity. Terminal design, calculation of pipe diameter by economic velocity. : first of all, according to the viscosity of the oil of the economic flow velocity, and then according to the business flow, obtains each crane oil pipe, tubing, suction pipe, the diameter of the discharge pipe. Second, according to the water hammer pressure of pipeline, pipe allowable stress, weld coefficient calculated each crane oil pipe, tubing, suction and discharge pipe of the pipe wall thickness. Finally, according to the business flow and flow velocity, viscosity, and oil pipeline39。s relative roughness e (e = mm) in this design, can according to the size of the Reynolds number, the oil flow in pipeline, calculated the hydraulic friction coefficient. Using darcy formula, can respectively calculate the crane each oil pipe, tubing, suction and discharge pipe of the friction loss, friction loss and the partial sum total can get all kinds of oil pipeline hydraulic friction loss ∑ h. Finally, according to the oil library process design manual tubing design and calculation result set.
