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.

摘要： An articulated branch assembly comprising pipe member and appropriately arranged combinations of fluid carrying swivels, ball joints, or rubber hose is fixed to the outboard end of a conventional marine cargo loading arm. The branch assembly is used for bunkering vessels while the arm is supported off the cargo manifold adjacent to the bunker manifold. Fitting marine cargo arms with the bunkering assembly and supporting the arm off the cargo manifold permits, for a large percentage of vessels, simultaneous bunkering and cargo transfer through the other cargo arms in the bank. The branch assembly also: eliminates in many cases the need for a separate bunker arm(s), avoids overstressing of the smaller, weaker bunker manifolds, and makes the bunker manifolds more accessible without resorting to long lengths of hose or auxiliary bunkering saddles.
