API-Compliant High Pressure Manifold For Oil Drilling Circulation Systems

High Pressure Manifold

The high-pressure manifold specifically refers to the high-pressure piping system on the discharge end of the drilling pump. It is the core pressure-bearing delivery equipment in the circulating system of an oil drilling rig, receiving the high-pressure drilling fluid output from the fluid end of the drilling pump. Serving as the high-pressure fluid passage connecting the drilling pump, air chamber (pulsation dampener), safety valve, kelly hose, swivel, and drill string, it is also commonly called the drilling high-pressure mud manifold in the industry. The entire assembly is subjected over the long term to high-pressure pulsating loads and erosion by drilling fluid containing solid particles, making it a pressure-bearing component with an extremely high risk level in drilling operations. Its reliability is directly related to drilling safety — once a washout or burst occurs, it can easily lead to major safety accidents.

Features
