Choke and Kill Manifold


Choke and Kill Manifold is used to control well kick and pressure. In case of well kick or blowout, Choke Manifold may control downhole pressure by valves open/close. Heavy slurry may be pumped into well by Kill Manifold to reach pressure balance. Besides, Choke Manifold can be applied to well cleanup and blow-off.  


Choke Manifold
  • Control pressure to prevent overflow and blowout.
  • Reduce wellhead casing pressure by relief function of choke valve.
  • Full-bore and two-way metal seal
  • Choke bean features hard alloy inside, delivering high resistance to erosion and corrosion.
  • The relief valve helps to reduce casing pressure and protect BOP. 
  • Configuration type: single-wing, double-wing, multiple-wing or riser manifold
  • Control type: manual, hydraulic, RTU 


Kill Manifold

  • Kill manifold is mainly used to kill well, prevent fire and assist in fire extinction.
