Pump Cavitation Got You Down? One-Piece Suction Manifolds
- 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.
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.
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.
