End-User Feedback Sand dropout causes flow restrictions, and pump cavitation is common. Traditional welded pipe manifolds create turbulence causing excessive abrasion on internal walls. Leaks along the weld seams are a regular nuisance. Acidizing well treatments attack weld seems. CO2 transfers at -30°F temperatures and can cause performance issues. Repairs consist of re-welding and/or using rubber washers with screws. Within the fracturing operation, there are multiple scenarios where down-time and pump failure can be avoided. Fig. 1 Fig. 2 Dixon innovation was demonstrated when developing the one-piece suction manifold that feeds slurry into high-pressure pumps. The manifold design was the result of hydraulic fracturing companies experiencing pump cavitation due to proppant dropout causing destructive flow restrictions. End-user input is invaluable, and the feedback has helped guide us to an economical solution. Dixon Solution The Dixon design combines unique flow geometry with one-piece iron manufacturing technology to increase flow, and eliminate 7-18 leak-prone weld seams. The 3-port and 5-port suction manifolds have been lab and field-tested, and the flow profile simulation demonstrates the differences between the welded pipe and Dixon manifolds.
