摘要： A system for suppressing cavitation in fluid pipeline passages such as fluid loading arms, particularly of the marine type, comprising extended turning vanes in the elbows of the loading arm, preferably in the upstream direction from the elbow tangent point, and also including the capability for adjusting the attack angle of the vane relative to the pipe axis. The combined effect of the extended vane and the negative attack angle improves cavitation performance to a greater extent than each of these expedients when used separately. This system obtains increased flow rates without significantly increasing the system back pressure and the adjustability of the attack angle will allow for optimization relative to changes in products and flow conditions.
