API 16C High-Pressure Choke and Kill Manifold System

  • Severe fluid erosion, solid particles, and extreme cyclic pressures during well control operations often cause rapid wear on choke valves, downstream piping, and control systems.
  • Built in strict accordance with API Spec 16C and NACE MR0175, we supply complete API 16C Choke & Kill Manifold skids alongside rapid-replacement critical components, including tungsten-carbide drilling choke valves, anti-erosion downstream nipples, and remote control consoles.
  • Ideal for onshore/offshore well control, managed pressure drilling (MPD), underbalanced drilling, and fast-turnaround MRO replacement parts.

Main Advantage & Solution

  • Rapid washouts and erosion on downstream piping during high-pressure pressure drops 10,000 – 25,000Psi).
    Solution: Downstream Anti-Erosion Nipples feature tungsten carbide inlays and flow-regulations to protect downstream manifolds, extending service life by over 3x.
  • Severe corrosion of control components on coastal or offshore rigs.
    Solution: Complete stainless steel console housing and integrated internal hydraulic routing ensure maintenance-free service in salt-spray conditions.

Application Scenarios

  • Well Control & Blowout Prevention: Real-time pressure balancing and fluid kill operations during kick events.
  • Managed Pressure Drilling (MPD) & Underbalanced Drilling: Fine-tuned pressure throttling for precision wellbore pressure management.
  • Rig MRO & Field Replacement: Direct-fit replacement chokes, erosion nipples, and control cabinets for existing drilling rig upgrades.
