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
