Structural Composition and Introduction of Each Component of High Pressure Manifold The entire discharge high-pressure manifold of the drilling pump is a modular assembly structure. Its main components are: high-pressure seamless straight pipes, high-pressure cast elbows, high-pressure tees, reducing nipples, high-pressure unions, flange assemblies, high-pressure gate valves, air chamber mounting base, safety valve mounting base, pressure gauge seat, and vibration-damping
