Choke Valve        
  
Pressure control equipment (choke valve) used to restrict and regulate the flow of well fluids to maintain a desired pressure and flow rate. Chokes typically have hardened internal replaceable parts specifically designed to resist erosion caused by high pressure, high velocity or abrasive fluids typically used as part of a Choke Manifold or Xmas Tree.

Choke Manifold   
A complete assembly of valves, Fittings, Flanges and Chokes configured to control and regulate the flow of fluid from a well bore.

Casing Spool        
A piece of well control equipment (flanged, welded or hub clamp) attached to the top of surface casing, allowing the attachment of Blowout Preventers during the drilling, phase and later used to hang and suspend a secondary string of casing set inside hung on a set of casing slips.
