Choke Stem – Precision Flow Control Component

Description :

A choke stem is a core part of an adjustable choke valve, used to control fluid flow by moving in and out of the choke seat or bean. By adjusting its position, operators can precisely regulate the flow rate of oil, gas, or other fluids under high-pressure conditions. It is critical to well control, production optimization, and flowback operations.

Key Features:

  • Material Options:
    • Hardened stainless steel (SS 410)
    • Inconel or Monel for high corrosion resistance
    • Tungsten carbide-tipped for superior wear resistance
  • Design Options:
    • Solid stem
    • Tapered, needle-point,
    • Precision-ground for smooth movement and sealing
  • Size Range:
    • Typically 1″ to 3″ diameters
    • Custom lengths and threads per API 6A or OEM specs
  • Pressure Ratings:
    • Suitable for high-temperature and sour service (NACE MR0175)

Applications:

  • Adjustable choke valves (manual or hydraulic)
  • Wellhead flow control
  • Well testing and flowback units
  • Managed Pressure Drilling (MPD)
  • Sand management systems

Benefits:

  • Accurate control of flow rate and pressure
  • High erosion and corrosion resistance
  • Interchangeable with various OEM choke assemblies
  • Enhanced service life in erosive or abrasive fluids
