Strategic Alliance OGCS - AXON Pressure Products 

Type 30 Choke

The AXON Type 30 Choke is available in a positive and adjustable (manual) design. The positive choke has a fixed size orifice and is used primarily in production applications. The adjustable choke has a manually operated needle or stem, which provides variable flow rates. Moreover, a visual indicator provides an indication of approximate orifice size for flow rate calculations. 

Features:

 

  • Positive and Adjustable designs available in 1", 2" or 3" maximum orifices.
  • Inlet and outlet sizes up to 4-1/16" bore in a 90° body configuration.
  • 2,000 to 15,000 psi maximum working pressures.
  • Adjustable design uses a visual indicator showing orifice size.

Type 31 Drilling Choke

Available in manual or hydraulic designs, the AXON Type 31 Drilling Choke has a standard cylindrical orifice gate and seat design. The gate and seat are solid tungsten carbide, which are reversible for two complete seal and wear areas. In addition, body configurations, gate and seat designs are interchangeable between the manual and hydraulic choke, allowing flexibility in choke and kill manifold designs. 

Features:

 

  • Designed and manufactured to API Specification 6A and ISO 10423 for Wellhead and Xmas tree equipment
  • 5,000 to 20,000 psi (34.5 to 138.0 MPa) maximum working pressures
  • Forged materials rated for H2S service per NACE MR0175.
  • Choke control consoles are designed to API Specification 16C for Choke and Kill Systems.

Type 32 Drilling Choke

The AXON Type 32 drilling choke utilizes two flat tungsten carbide discs with a half round cut out in each disc, available in manual and hydraulic configurations. One disc remains stationary while the other rotates, providing a variable orifice according to requirements. In addition, the lapped matting surfaces of the discs provide a positive seal when the choke is closed. Moreover, the choke control panels are available in single or dual choke operation. 

Features:

 

  • 5,000 to 15,000 psi (34.5 to 103.5 MPa) maximum working pressures.
  • Forged materials rated for H2S service per NACE MR0175.
  • Choke control panels are designed to API Specification 16C for Choke and Kill Systems.

Chokemaster™ Drilling Choke

Available in manual, hydraulic and electric servo motor actuation, AXON’s Chokemaster™ Drilling Choke features a modular design that can be customized to specific rig requirements, as well as adapted when these requirements evolve. This ability to configure a basic valve platform with à la carte operation selections, in addition to maintaining complete spares interoperability within the equipment fleet, allows for ultimate flexibility.  

Features:

 

  • Inlet and outlet sizes 3-1/8”, 3-1/16”, or 4-1/16” bore in a 90° body configuration.
  • 5,000 to 20,000 psi (34.5 to 138.0 MPa) maximum working pressures
  • Orifice sizes available in 1.75”, 2”, and 3” nominal diameters.
  • Base valve assembly interchangeable between all manual and remote actuation options.
  • Reversible gate and seat provides double wear surfaces.
  • Optional davit arm allows for quick, one-person change out of trim.
