Product Definition and Core Functions of High Pressure Manifold The high-pressure drilling fluid pressurized by the drilling pump must rely on the high-pressure manifold for delivery. The high-pressure manifold is an integrated piping assembly composed of pressure-bearing pipe components such as high-pressure straight pipes, high-pressure elbows, tees, reducing couplings, flanges, unions (由壬), valves, and pulsation dampener short nipples. Core functions: 1. High-Pressure
